Slackware -current CHANGES_AND_HINTS.txt

This file documents the instructions for upgrading to Slackware -next, the packages added, removed, renamed, and/or split during the development cycle from Slackware 13.37 through -next, and some potential “gotchas” that users can avoid by arming themselves with a little knowledge.

*** INSTRUCTIONS FOR UPGRADING FROM 13.37 ***

Follow the instructions detailed in the UPGRADE.TXT located in this

directory.  

Note that upgrading from a Slackware version earlier than 13.37 is NOT

supported at all and will most likely not work.

* OTHER NOTABLE CHANGES AND HINTS *

Use one of the provided generic kernels for daily use. Do not report

bugs until/unless you have reproduced them using one of the stock 
generic kernels.  You will need to create an initrd in order to boot
the generic kernels - see /boot/README.initrd for instructions.
The huge kernels are primarily intended as "installer" and "emergency" 
kernels in case you forget to make an initrd.  For most systems, you 
should use the generic SMP kernel if it will run, even if your system is 
not SMP-capable.  Some newer hardware needs the local APIC enabled in the 
SMP kernel, and theoretically there should not be a performance penalty 
with using the SMP-capable kernel on a uniprocessor machine, as the SMP 
kernel tests for this and makes necessary adjustments.  Furthermore, the 
kernel sources shipped with Slackware are configured for SMP usage, so you 
won't have to modify those to build external modules (such as NVidia or 
ATI proprietary drivers) if you use the SMP kernel.
If you decide to use one of the non-SMP kernels, you will need to follow the
instructions in /extra/linux-3.2.21-nosmp-sdk/README.TXT to modify your
kernel sources for non-SMP usage.  Note that this only applies if you are
using the Slackware-provided non-SMP kernel - if you build a custom kernel,
the symlinks at /lib/modules/$(uname -r)/{build,source} will point to the
correct kernel source so long as you don't (re)move it.

As with 13.37, the system udev rules now reside in /lib/udev/rules.d/ instead

of /etc/udev/rules.d/ in older versions.  There should never be a reason 
to edit anything in /lib/udev/rules.d/, so if you think you have a case 
where this is required, either you're wrong or it needs to be addressed in 
the upstream source.  However, you can override default rules by placing 
one with an identical name inside /etc/udev/rules.d/  The rules files in 
/etc/udev/rules.d/ are still intended to (maybe) be edited as needed by 
local system administrators, and as such, the rules for optical and network 
devices will still be placed there.

Speaking of udev, pay particular attention to 70-persistent-net.rules and

70-persistent-cd.rules in /etc/udev/rules.d/ -- these two are automatically
generated by the system.  If you remove, add, and/or replace some hardware
(specifically network cards and/or optical drives) in a machine, you will
probably need to edit one or both of the rules files mentioned above.

If you are upgrading (as opposed to a new install), there are some stale files

in /etc/modprobe.d/ that you will need to remove:   blacklist.conf, 
bluetooth.conf, isapnp.conf, psmouse.conf, and usb-controller.conf
See /etc/modprobe.d/README for a more detailed explanation.

Both printing and scanning require that your user account be a member of the

"lp" group (membership in the "scanner" group is no longer needed); we had
 to configure sane to use the "lp" group or else multifunction devices 
 (e.g. print/scan/copy units) would only do one or the other (depending on
 whether the group ownership was "lp" or "scanner").

Xorg no longer uses /etc/X11/xorg.conf by default (and in most cases, there

is absolutely no need for it).   You can still create an xorg.conf file if 
you wish, or you can create some minimal xorg.conf snippets with only the 
specific contents that you wish to override (as an example, to use a binary
video driver) as separate files in the /etc/X11/xorg.conf.d/ directory.
/usr/share/X11/xorg.conf.d/ is the "packaged" configuration directory; all
files ending with ".conf" in this directory are used by the X server 
unless there is an identically-named file in the local sysadmin directory.
The local sysadmin config directory is /etc/X11/xorg.conf.d/ - all files
ending with ".conf" in this directory are parsed.  
There are several default config files in /usr/share/X11/xorg.conf.d/:
  * 10-evdev.conf
      a "catchall" file for input devices using the evdev driver; this 
      should work for most hardware in the absence of a better driver
  * 50-synaptics.conf
      overrides the earlier 10-evdev.conf file and uses the synaptics 
      driver for all touchpads
  * 50-wacom.conf
      overrides the earlier 10-evdev.conf file and uses the wacom driver 
      for Wacom tablets
  * 90-keyboard-layout.conf
      this sample ("normal" en layout) keeps the "old" default of 
      allowing Zap'ing the Xserver.
If you need to modify any of these defaults, then copy the relevant file
from /usr/share/X11/xorg.conf.d/ to /etc/X11/xorg.conf.d/ and edit the
copy.
Regardless of your chipset (though it seems more common with intel), if KDE
crashes on startup, try disabling the Composite extension (which will also
disable all of the fancy desktop effects).  Place the following content in
a file at /etc/X11/xorg.conf.d/disable-composite.conf:
  Section "Extensions"
    Option "Composite" "Disable"
  EndSection

Now that KMS (Kernel Mode Setting) for graphics cards has (mostly) stabilized,

it is enabled by default for intel, ati, and nvidia graphics chipsets.  It
is possible to disable it use "nomodeset" as a kernel append in lilo.conf,
but Xorg will not work at all on intel (and some ati) chips if you do that.

If you want to change the resolution of the KMS console, that can be done
with something like this as a kernel append in lilo.conf:
  append="video=1024x768"
Speaking of lilo.conf and KMS, make sure you use either vga=normal or 
vga=extended -- some of the framebuffers don't like KMS very much...

If you see some log messages like this:

  mdadm: sending ioctl 1261 to a partition!
They're completely harmless - do not be alarmed.  Here's why: 
http://lists.debian.org/debian-kernel/2012/03/msg00446.html

The version of logrotate in Slackware 14.0 added an “su” option to define

user/group for rotation.  Logrotate now skips directories which are world 
writable or writable by a group which is not "root" unless the "su" 
directive is used.  This has ramifications for third party packages that
installed e.g. /var/log/somedir owned by a non-root user and/or group.

If you are using a KVM switch, you might experience problems with the mouse

when switching from one system to another.  If so, you probably need to be
using the imps protocol for the psmouse driver, and that's a simple fix:
Copy /lib/modprobe.d/psmouse.conf to /etc/modprobe.d/psmouse.conf, then
uncomment the following line in /etc/modprobe.d/psmouse.conf:
  #options psmouse proto=imps
Next, unload and reload the psmouse module (do this as root):
  modprobe -r psmouse ; modprobe psmouse

If you have set up an encrypted root partition, you will need to have access

to your keyboard in order to type the passphrase.  This may require you to 
add the uhci-hcd and usbhid modules to your initrd image if you have a USB 
keyboard.  Also note that if you are using a non-US keyboard, you can use the
'-l' parameter to the 'mkinitrd' command in order to add support for this
keyboard to your initrd.

If you have permission errors when attempting to burn a cdrom or dvd image,

such as the following:
  /usr/bin/cdrecord: Operation not permitted. Cannot send SCSI cmd via ioctl
then cdrecord almost certainly needs root privileges to work correctly.
One potential solution is to make the cdrecord and cdrdao binaries suid root,
but this has possible security implications.  The safest way to do that is 
to make those binaries suid root, owned by a specific group, and executable
by only root and members of that group.  For most people, the example below
will be sufficient (but adjust as desired depending on your specific needs):
  chown root:cdrom /usr/bin/cdrecord /usr/bin/cdrdao
  chmod 4750 /usr/bin/cdrecord /usr/bin/cdrdao
If you don't want all members of the 'cdrom' group to be able to execute the
two suid binaries, then create a special group (such as 'burning' which is
recommended by k3b), use it instead of 'cdrom' in the line above, and add
to it only the users you wish to have access to cdrecord and cdrdao.

Input methods for complex characters (CJK, which is shorthand for Chinese,

Japanese, Korean) and other non-latin character sets have been added. These
input methods use the SCIM (Smart Common Input Method) platform.
The environment variables for SCIM support are set in /etc/profile.d/scim.sh
The requirements for getting SCIM input methods to work in your X session
are as follows:
(1) Use a UTF-8 locale. Look in /etc/profile.d/lang.sh for setting your
    language to (for instance) en_US.UTF-8. As a word of warning: maybe you
    should leave root with a non-UTF-8 locale because you don't want root's
    commands to be misinterpreted. You can add the following line to your
    ~/.profile file to enable UTF-8 just for yourself:
      export LANG=en_US.UTF-8
(2) Make the scim profile scripts executable. These will setup your
    environment correctly for the use of scim with X applications. Run:
      chmod +x /etc/profile.d/scim.*
(3) Start the scim daemon as soon as your X session starts. The scim daemon
    must be active before any of your X applications. In KDE, you can add a
    shell script to the ~/.kde/Autostart folder that runs the command
    "scim -d". In XFCE you can add "scim -d" to the Autostarted Applications.
    If you boot your computer in runlevel 4 (the graphical XDM/KDM login)
    you can simply add the line "scim -d" to your ~/.xprofile file.
    This gives you a Desktop Environment independent way of starting scim.
When scim is running, you will see a small keyboard icon in your system tray.
Right-click it to enter SCIM Setup. In 'Global Setup' select your keyboard
layout, and you are ready to start entering just about any language
characters you wish! Press the magical key combo <Control><Space>
in order to activate or deactivate SCIM input. The SCIM taskbar in the
desktop's corner allows you to select a language. As you type, SCIM will show
an overview of applicable character glyphs (if you are inputting complex
characters like Japanese).

If you have an older machine (with a BIOS released prior to 2001) and it will

not power off on shutdown, try adding this to your kernel's lilo stanza:
  append = "acpi=force"

If you have a Thinkpad T400 or T500, you probably want to append “pci=reboot” to the kernel boot parameters. For more information about this issue, see
