Installation Lifecycle

The Installation consists of a number of distinct stages:

  1. Acquiring all required hardware
  2. Setup of the Raspberry Pi hardware
  3. Downloading the Slackware assets
  4. Verifying the Slackware assets
  5. Writing the Slackware Installer to the Micro SD card
  6. Writing the Slackware Installation Media to the USB flash drive
  7. Booting the Slackware Installer
  8. Installing Slackware
  9. Completing the installation
  10. Booting the Slackware OS
  11. Post installation configuration and tweaks


Raspberry Pi 3 support

Using the GUI on the Raspberry Pi 3 is not recommended due to the lack of RAM - the screen will typically freeze. It is recommended that the Raspberry Pi 3 is used headless (remote access).



This hardware list is what has been recommended by the Slackware community as a good starting point for setting up a Raspberry Pi. There are a plethora of peripherals available for the Raspberry Pi which you can use with Slackware.
SD cards: Some SD cards are known to have issues on the Raspberry Pi4. Please use one of the brands provided in the hardware table below.
Please purchase the hardware from any vendor: Slackware ARM has no affiliation with The PiHut, but it is a useful one-stop-shop for RPis and accessories, and this author can attest to good service within the UK.
Item Specification/Type Required? Notes
Raspberry Pi 4 Model B 4GB and 8GB RAM models have been tested Yes This is the bare board
'Ice Tower' CPU heat sink & cooling fan A heat sink or CPU is required This has been recommended as a suitable fan for high-CPU workloads.
Power supply Official Raspberry Pi PSU Yes It's best to use the official PSU as others can cause instability over time.
Inline power switch - Optional but recommended The Raspberry Pi 4 does not have reset nor power buttons on the board. Reports from the Slackware community suggest that the power socket on the Rpi will become damaged over time from wear. This inline power switch prevents damage to the RPi.
Micro to full-size HDMI adapter - Optional Depends on your local setup and whether you wish to connect an HDMI monitor to the RPi.
Real Time Clock (RTC) Adafruit PiRTC - Precise DS3231 Optional This RTC been recommended by the Slackware community.
Battery for RTC Lithium 3volt CR1220 Optional Depends on whether you use the RTC module. This enables the RTC to maintain the time whilst the RPi is powered down.
Dupont wires Female to male Optional This is to wire in the RTC module, as the large sized CPU heat sink prevents the RTC module from connecting directly to the GPIO. These wires are also useful for connecting other peripherals to the RPi's GPIO.
SATA storage / SSD Minimum useful size: 30GB Required Will contain the Operating System. You can install to other storage, but this documentation covers this particular configuration only. The Kingston-SA400S37-240G has thoroughly proved itself in the Slackware ARM build infrastructure - most build machines use these, but any SSD or spinning hard disk should work
USB to SATA adapter - Required Many models will work, but this one has been tested on many of this author's ARM hardware.
USB to Serial adapter PL2303 chip. Other models may work, but this one has been tested. If your model has the option to set voltages, ensure 3volts is set! Optional A USB to Serial/UART adapter is recommended if you want to access the console remotely, but is unnecessary if you only plan on using an HDMI monitor. This document covers installing using an HDMI monitor - you can find information about connecting the Serial/UART adapter at the foot of this document
USB Flash Drive ('USB stick') 8GB minimum capacity Required This will contain the Slackware Installation Media for use during the installation phase only.
Micro SD Card 8GB minimum capacity, Class 10 (fast speed) Required Initially used to boot the Slackware Installer, and subsequently transformed into Slackware's /boot partition.
USB keyboard and mouse Standard peripherals Required A USB keyboard and mouse are required for this Slackware installation guide but are not required for the running of the OS. Slackware can also be installed headless (without a keyboard or monitor) over the Serial/UART or SSH (but this isn't documented).

In addition to the examples of tested hardware, here follows other storage devices and peripherals that have been tested by the Slackware community.

Type Details
Micro SD card Gigastone 32GB
Micro SD card Kingston 64GB microSDHC Canvas Select Plus
Micro SD card Kingston SDCG3
Micro SD card SanDisk 16GB
USB to SATA adapter (alternative to the one in the table above) SKL Tech
Alternatives to SSD

If you prefer to use NVME storage, these have been tested:

Notes on storage setup

The setup documented here (2.5“ SSD connected to a USB-to-Serial adapter for power and data) has proven stable for this author.

It is possible to create a 3rd partition on the Micro SD card ('MMC') which can house the Slackware OS. However, this is not recommended due to the longevity of this type of storage - particularly if it has high I/O.

Computing / Network Environment

Item Specification Notes
Host Computer: an Internet-connected computer running an existing Linux distribution Preferably a full installation of Slackware x86/64, but any distribution that can provide the required Python environment and HTTP server module. The Host Computer needs approximately 5GB free storage to download the required software assets. You must be able to obtain root access to this Host computer. This will be used to download the Slackware distribution from the Internet, write the Slackware Installation media to the USB flash drive and Micro SD card.

Hardware Setup

In this section we'll prepare the physical aspects of the Raspberry Pi4 to receive Slackware Linux.

Note that this is just one of a vast array of hardware configurations for the Raspberry Pi4. If you have a different configuration that's already working, you can skip to the 'Software and Network Environment Setup ' section
Attach the base board

Attach the base board to the RPi4 using the brass spacers. Ensure that each brass spacer is screwed into the base board, as shown.

The base board comes with the 'Ice Tower' CPU cooling pack (as mentioned within the Hardware Requirements table). Other RPi “open” case designs would connect the RPi in a similar manner (e.g., the bottom element of Micro Connectors' Acrylic Stackable Raspberry Pi case)
Screw four spacers to the top to secure the board to the platform

Attach the thermal tape to the CPU

Lay one of the pieces of thermal tape atop the CPU as shown:

Attach the heat sink brackets

Pay close attention to the positioning of the brackets, otherwise it won't sit on the board properly.
Use the symbols on the brackets for orientation
Secure the board to the platform

Only apply 3 nuts as shown. The fourth brass-coloured 'spacer' will be used to seat the RTC (Real Time Clock). If you do not have an RTC, secure this with a fourth nut.
Attach CPU fan power wires

RTC (Real Time Clock): Insert battery

RTC (Real Time Clock): Wiring

RTC (Real Time Clock): Attach to Raspberry Pi

Add all other peripherals required to install Slackware
  • Connect the storage - ensure that it's connected to a blue USB 3.0 port
  • Connect the Ethernet cable (optional - required if you want to set the date via NTP before commencing installation)
  • Connect the HDMI cable
  • Connect the USB keyboard and mouse

The basic hardware setup is complete.

Downloading the Slackware assets

In this section, we'll prepare the Linux Host Computer to receive and download the Slackware assets required for the installation.

1. Downloading the Slackware Linux AArch64 Distribution and Installation Assets

The '$' prefixes in the commands indicates the shell prompt - it's not to be typed/copied

Open a shell on the Linux Host Computer.

Prepare a directory to hold and serve the Slackware Distribution

We'll download the Slackware Linux distribution into a directory named 'slackware'.

$ cd ## this returns to the root of your home directory
$ mkdir slackware
$ cd slackware
Determine where you are within the Host Computer's Filesystem
$ pwd
Note the directory location returned - you'll need this later
Installing the Slackware ARM GPG key

The Slackware ARM GPG key will be used to verify the Bootware and Slackware Installation images.

$ curl -sSL https://www.slackware.com/infra/keys/arm/GPG-KEY | gpg --import -
Set the version of Slackware AArch64 to download

At the time of writing, the only version available is 'current'.

$ SLKVER=current
Set the distribution server

If you are using a mirror server rather than the master Slackware ARM server, set it here. The format is: <hostname>::<rsync module name>

$ SLKSRV=ftp.arm.slackware.com::slackwarearm
Download the Slackware Linux installer for the BCM2711 AArch64 platform
rsync -PavL $SLKSRV/platform/aarch64/bootware/installer/slackwareaarch64-${SLKVER}/bcm2711_rpi4.sdimg_latest.img.xz .
rsync -PavL $SLKSRV/platform/aarch64/bootware/installer/slackwareaarch64-${SLKVER}/bcm2711_rpi4.sdimg_latest.img.xz.asc .

The Slackware Installer images are approximately 300MBytes in size.

Download the Slackware tree verification tool
rsync -PavL $SLKSRV/platform/all/scripts .
Download the Slackware AArch64 tree

You will now download the Slackware distribution. This contains all of the software included within Slackware.

rsync \
   --exclude '*/source/*' \
   --delete -Prlvv \
   $SLKSRV/slackwareaarch64-${SLKVER} .

The Slackware distribution is approximately 4.5GBytes in size.

Verify the assets

Verify the digital signature of the verification tool:

gpg --verify-files scripts/slacksigchk.sh.asc

The output will be similar to this. You are looking for 'Good signature from Slackware ARM…'

gpg: assuming signed data in 'scripts/slacksigchk.sh'
gpg: Signature made Wed 24 Nov 2021 06:07:44 PM BST
gpg:                using RSA key F7ABB8691623FC33
gpg: Good signature from "Slackware ARM (Slackware ARM Linux Project) <mozes@slackware.com>" [unknown]
gpg: WARNING: This key is not certified with a trusted signature!
gpg:          There is no indication that the signature belongs to the owner.
Primary key fingerprint: 36D3 7609 2F12 9B6B 3D59  A517 F7AB B869 1623 FC33

Verify the Bootware and Slackware tree:

chmod 755 scripts/slacksigchk.sh
./scripts/slacksigchk.sh slackwareaarch64-${SLKVER}
If you see 'BAD signature' you should re-download as it may have become corrupt. If this doesn't help, drop a note to the Slackware ARM forum

Writing the Slackware assets to the Micro SD and USB stick

Elevate yourself to root

On your Host Computer, obtain root:

The # prefix indicates that you're using the root user - it's not to be typed in!
$ su -   ## Note the hyphen - it's required

Write the Slackware Installer to the Micro SD card

Check what block devices are present

Prior to inserting the Micro SD Card into the USB adapter, we need to see what's already present within the OS so that we can easily locate our Micro SD card:

# lsblk -d
sda    8:0    0 465.8G  0 disk 

As you can see, this Host Computer there is a single storage device - sda.

Insert the Micro SD card into your USB Card Reader and connect the adapter to a free USB port on the Host Computer

Run lsblk again:

# lsblk -d
sda      8:0    0 465.8G  0 disk
sdc      8:32   1    58G  0 disk
sdd      8:48   1     0B  0 disk

As you can see, sdc is 58GBytes in size. This is the Micro SD card (in this example, it's labeled as '64GB' on the exterior of Micro SD card).

If your Micro SD card has existing partitions, you will not see them surfaced in this list - use lsblk -b to view them.

You'll also observe the presence of sdd - often the USB adapter itself obtains a block device. You can ignore this as it's 0Bytes.

Write the Slackware Installer to the Micro SD card

Enter the directory into which the Slackware assets were downloaded previously:

# cd ~mozes/slackware ## Substitute with the path you noted earlier 
# xzcat bcm2711_rpi4.sdimg_latest.img.xz > /dev/sdc ## Substitute/dev/sdc with the correct block device
# sync
Remove the MicroSD card from the Host Computer

You may now disconnect the USB adapter/remove the Micro SD card from the Host Computer.

Write the Slackware Installation Media to the USB stick

Now that the Micro SD card (and adapter) has been removed from your Linux Host Computer, we can begin setting up the USB stick to receive the Slackware Installation Media.

Insert the USB stick into the Linux Host Computer

Still as root, type lsblk -d

# lsblk -d
sda    8:0    0 465.8G  0 disk 
sdb    8:16   1  28.6G  0 disk 

As you can see, the USB stick has appeared as sdb and is 28GB in size.

All data will now be erased from this USB stick!
Create an ext4 file system on the USB stick
# mkfs.ext4 -FL SLKins /dev/sdb ## Substitute /dev/sdb with the appropriate one for your Host Computer
mke2fs 1.46.4 (18-Aug-2021)
Writing superblocks and filesystem accounting information: done   
If your USB stick has existing partitions or file systems on it, you will receive warning messages - this is normal
Mount the USB stick
The mount point '/mnt/hd' is a valid mount point for Slackware, but other Linux distributions may require using a different path. If you're using /mnt/hd already, pick a different mount point.
# mount /dev/sdb /mnt/hd 
Copy the Slackware Installation Media to the USB stick
Remember to change the mount point if you're not using /mnt/hd
Your working directory should still be where you downloaded the Slackware assets into (which, following this Installation Guide, is /home/mozes/slackware)
# rsync -Pav slackwareaarch64-* /mnt/hd/ 
Umount the USB stick
# umount /mnt/hd
# sync
Logout from the root user

We no longer need to use the Host Computer, so you can logout of the root shell.

# logout

Installing Slackware

To proceed, you must have:

  • Connected the storage to the Raspberry Pi 4
  • Connected the HDMI monitor
  • Connected the keyboard (and optionally, mouse)
  • Optionally connected the Ethernet cable to set the date via NTP from the Internet
  • Inserted the Micro SD card containing the Slackware Installer
Encrypted storage

If you'd like to encrypt your storage, check the Disk Encryption Guide.

Begin installation
Disconnect any USB storage devices that aren't required for the OS installation
Power on the Raspberry Pi 4

Apply power to the Raspberry Pi and after a few seconds, you will see the following on screen:

It takes several seconds to load and boot the installer, and it may take several seconds more for any further output to appear on the HDMI monitor. The process of obtaining an IP address via DHCP can also delay the ability to interact with the Installer.

Once an IP address has been obtained, you will be presented with a prompt. Press ENTER

Set the keymap

Set the date/time

Even if you have a battery pack for the RTC (Real Time Clock), the date on your system may be incorrect. We will sync the date from a highly-available NTP server:

ntpdate clock.akamai.com
hwclock -w

Setup disk partitions

For this installation a basic partitioning scheme will be created.


Partition number Device name Size Purpose
1 /dev/sda1 4GB Swap
2 /dev/sda2 Rest of storage OS root ('/') partition
/boot will reside on the Micro SD card and is automatically configured by the Slackware Installer

Open fdisk against the /dev/sda block device. In this guide, /dev/sda will be your primary storage, and in this guide is the SSD connected to the USB adapter.

fdisk /dev/sda

Clear an existing partition table: Press 'o' to clear the partition table

Create the Swap partition:

Type 'n' for new partition:

Type 'p' for primary partition type:

Press ENTER for the 'First sector'

Type '+4G' for the 'Last Sector'/size:

Change the partition type to 'Swap'. Type 't' then hex code '82':

Create the partition for the root filesystem ('/'):

Type 'n' for new partition. Press ENTER to accept the defaults - this will create partition 2 as the maximum size available.

Type 'a' to mark the root partition (number 2) as bootable Type '2' to select partition 2.

Type 'p' to print to view the partition table.

Type 'w' to write the partition table:

fdisk will now exit.

Load the Setup menu

Setup Swap partition

Select and format the partition for the OS' root file system

Resize /boot partition to full extent

The Micro SD card that contains the /boot partition presently occupies approximately 1GB. Most MicroSD cards are several GBs in size. This option will resize the partition to its full capacity to avoid wasting storage. If you plan on manually adding partions to this later, you will want to choose 'No' here.

It's important that the Micro SD card is not used for heavy read/writes as it'll reduce its life span and will cause your system not to boot. This option exists simply to avoid wasting space on the MicroSD card.

Boot Loader Configuration

The Installer will configure the Boot Loader and the OS' /etc/fstab automatically:

On the ARM platform, the Swap and root file systems are addressed by labels (see above: 'LABEL=') where as on x86/64 it's addressed by a direct reference to the block device (e.g. /dev/sda). The Slackware Installer will label swap partitions as 'SLKswap<x>', and the root file system 'SLKroot'. Other labels in use are 'SLKboot' for the OS boot partition (/boot), and 'SLKhwm_bw' for the Hardware Model Bootware partition (/boot/platform/hwm_bw). These labels are pre-labeled on the SD card image that you deployed and won't be presented during the installation process.

The rationale behind this divergence is that on x86 the root file system is typically on a storage bus (SCSI, SATA, ATA), where the physical configuration (which port the storage is connected to) of the storage rarely changes. This can be the case on ARM, but it's generally to a lesser extent and the root file system may be connected to a hot-plug bus such as USB. This lends itself to the risk of device re-ordering across boot cycles (e.g. /dev/sda becomes /dev/sdb), causing boot failure.

Please be aware that the Slackware Installer only labels the swap and root file system. Therefore you are advised to manually label the file systems and modify the OS /etc/fstab accordingly. If you have only a single storage device and don't plan on adding more, you can use the settings that the Slackware Installer configures.

Select Source Media
  • Insert the USB stick into one of the blue USB3 ports of the Raspberry Pi.

Pick option '2 - Install from a Slackware USB stick'

Package Series Selection

You can now choose the package sets to install. The recommendation is to install everything. A full Slackware installation will occupy approximately 15GB.

If you do not plan to use the graphical window manager such as KDE, you should de-select it.

Pick the 'terse' option:

The packages will begin installing:

Configure the Console Settings

If you plan on using the UART/'Serial' console, you should select 'No' here. If you plan on exclusively using an HDMI monitor, you should pick 'Yes'.

This setting can be reset to the default by editing /boot/extlinux/extlinux.conf and removing the 'console=' setting once the OS has booted

Remove the Slackware Installer from the SD card

The Micro SD card is transformed from being the Slackware Installer into the Slackware OS's /boot partition. At this stage, if the installation has worked for you (at certain points in the Slackware installer you are past the point of no return) you can delete the Installer. However, if something has gone wrong you can reset the Raspberry Pi and reboot the installer without having to re-deploy the Slackware Installer image from your Linux Host Computer.

Generally you should say 'Yes' here.

You may be tempted to retain the Slackware Installer, but note that the Installer contains Linux Kernel modules for the Kernel that the Installer was originally shipped with. This means that as soon as you upgrade the Slackware Kernel package, the Installer will fail to boot. The option to retain the Installer is present purely because on a number of occasions, this author only realised that the installation was incorrectly performed upon completion, and needed to reinstall. Retaining the Installer avoids the requirement to re-deploy the image to the SD card.
Post Installation Configuration

The Slackware Installer will walk you through the standard Slackware setup. The on-screen instructions will suffice.

Select a Console Font

It's recommended for the Raspberry Pi that a larger console font is configured for the virtual console.

The recommended font is 'ter-732b.psf'. This is the font used within the Installer.

Continue Post Installation Configuration

Configure GUI Window Manager

This author recommends using XFCE as it's light weight versus KDE.

Continue Post Installation Configuration

Slackware Setup Complete

Disconnect the USB stick

You must now physically remove the USB stick that contains the Slackware Installation Media.

Reboot into the Slackware OS

Generally you'll want to reboot into the OS.

However, if you are planning on setting up RAID or need to customise the Operating System Initial RAM Disk, you should select 'Shell'.

The Slackware OS will be found within '/mnt'. You can use the 'os-initrd-mgr' tool (Video tutorial).

Booting the Slackware OS

Login to the Slackware OS

You may now login as 'root', using the password you set within the installer.

Post Installation Configuration

There are a few post-installation configuration tasks to complete.

Initial Time/Date Sync

If Internet access is available to the Raspberry Pi, prior to proceeding with any further setup, you may wish to set the time now as a one-off event:

Elevate yourself to root and use ntpdate:

$ su - 
# ntpdate rolex.ripe.net  # or pick your favourite NTP server
# hwclock -w # writes the date to the RTC
# logout

Add a plebeian user

You should add a plebeian (non-root) user using the 'adduser' tool.

This is documented here.

NTP (Network Time Protocol) setup

Even if your Raspberry Pi has an RTC (as documented in this guide), you may wish to configure it to set time from an Internet NTP Server. The Raspberry Pi requires continuous Internet access for this to function.

Use a graphical login manager

If you prefer to use a graphical login manager, you can configure the default runlevel as 4:

su - 
sed -i 's?id:3:?id:4:?g' /etc/inittab

Managing Slackware on the Raspberry Pi

Keeping the Slackware OS up to date

One of the preferred tools to keep your system up to date is slackpkg.

Upgrading the Kernel: in Slackware x86/64 manual steps are required after upgrading the Kernel packages. In Slackware ARM, you simply upgrade the Kernel packages and reboot.

Loading Additional Linux Kernel Modules at Boot Time

There are a number of peripherals that may require Kernel modules loading early on in the boot sequence. An example of this would be RTCs (Real Time Clocks).

To load Kernel modules during the early boot sequence, read:


As root, the easiest way is to create

mv /boot/local/load_kernel_modules.post.sample /boot/local/load_kernel_modules.post

Then add the appropriate module loading commands to: /boot/local/load_kernel_modules.post You can also add shell code here to initialise a peripheral - writing something to the peripheral's Kernel interface, for example.

Customising the Slackware Linux Kernel

If you'd like to customise the Linux Kernel, the easiest way is to follow the HOWTO guide and use the Slackware ARM Kernel build script to create new packages.

This document also covers using the Raspberry Pi Kernel fork (although this is not recommended).

Reducing Boot Time

Slackware ARM ships with a generic OS InitRD (Operating System Initial RAM Disk - the environment that prepares the machine to boot the Operating System Proper), so as to support a wide range of Hardware Models.

However, this isn't the optimal setup once the Slackware OS has been installed because the generic OS InitRD typically exceeds 250MB, which in some cases can add several seconds to the boot time whilst it's loaded from the SD card.

The os-initrd-mgr (Operating System Initial RAM Disk Manager) tool has an option to synchronize the OS InitRD's Kernel modules with only those presently loaded within the Operating System.

To do this:

$ su -c 'os-initrd-mgr --sync-loaded-kmods' -  # note the final -
To have this setting persist across Kernel upgrades, you must upgrade the a/kernel-modules package before a/kernel. If not, it'll revert to the generic OS InitRD until you next reboot. If you are using slackpkg to manage upgrades, this is handled for you.

This option isn't the default, but you can make it so by following the instructions within /etc/os-initrd-mgr.conf.sample

This way when you upgrade the Kernel packages in the order described above, it'll automatically synchronize the modules.

os-initrd-mgr has a safety check to only proceed when the running Kernel and incoming Kernel are at the same major version and patch level.

For example, when running Linux 5.17.1, upgrading to 5.17.2 will work; but an upgrade of Linux 5.17.1 → 5.18.1 will require a reboot then to run os-initrd-mgr again to re-sync.

If at any point you want to revert to the generic OS InitRD, simply reinstall the a/kernel package (and unset the setting if you configured it in /etc/os-initrd-mgr.conf).

Managing the Raspberry Pi Firmware

Do not use the 'rpi-update' script (found in other distributions) - this is unnecessary and is incompatible with Slackware.

The Raspberry Pi firmware is managed by the Slackware packages.


The Raspberry Pi boots from a FAT partition on the Micro SD card. This partition contains the closed-source proprietary boot loader, firmware and various other assets it requires. It is mounted within the Slackware OS under /boot/platform/hwm_bw (on other distributions these files reside within /boot).

These assets are provided and managed by the Slackware package 'a/hwm-bw-raspberrypi'.

Simply upgrading to the latest available Slackware packages will update this firmware.
Firmware for the EEPROM

The Slackware package 'a/hwm-bw-raspberrypi' contains the available firmware that can be programmed to the Raspberry Pi's EEPROM.

This firmware update requires manual action - see below

To update the firmware on your RPi's EEPROM; as root:

  $ rpi-eeprom-update -d

This will report if there's newer firmware available.

To update the firmware:

  $ rpi-eeprom-update -d -a

If the firmware was successfully updated, reboot:

  $ reboot
The EEPROM tool configuration file is: /etc/rpi-eeprom-update. By default we're using firmware from the “critical” (most stable and well-tested) release channel, but you can change it within that configuration file.
Raspberry Pi SoC/IP Core Firmware

The firmware for the peripherals on the Raspberry Pi Hardware Models is contained within the Slackware 'a/kernel-firmware' package.

Simply upgrading to the latest available Slackware packages will update this firmware.

Using Device Tree Overlays

Device Tree Overlays can be configured within the Raspberry Pi's Native Boot Loader configuration file: /boot/platform/hwm_bw/config.txt

Note: The Raspberry Pi's Native Boot Loader configuration is outside of the management of the Slackware OS so you need not be concerned with any automatic modifications.

Using the Serial/UART adapter

This documentation discusses using the Raspberry Pi without the UART/Serial console.

If you'd like to use one, there are two that have been tested.

USB Serial Device converter: Prolific Technology Inc / PL2303

This image below shows the PL2302 (the Serial adapter listed in the Hardware table at the head of this document) connected to the Raspberry Pi:

USB Serial Device converter: FTDI / FT232RL

This is the model shown here.

Using the USB Serial Device converter on the Linux Host Computer

Once wired up, connect the USB end of the adapter into your Linux Host Computer, and use the following command.

This assumes that there are no other similar adapters occupying /dev/ttyUSB0. If so, you will need to adjust the device name accordingly (e.g. perhaps /dev/ttyUSB1).
screen  -T screen-256color /dev/ttyUSB0 115200

Known Limitations / Bugs

Issue Work around Notes
Poor X11 performance None presently Bug reportPresently the required drivers ('VC4') is not in the mainline Linux Kernel. Will keep track upstream.
