Tips and Hints
Slackware
- We recommend running Studioware on a stock vanilla Slackware Installation.
Mate
- MATE-1.6.2 build script replaces the following Studioware packages on 14.1:
- atkmm-2.22.7-i486-1_msb > atkmm-2.22.4-i686-2se.txz [libraries]
- cairomm-1.10.0-i486-1_msb > cairomm-1.9.8-i686-2se.txz [libraries]
- glibmm-2.36.2-i486-1_msb > glibmm-2.32.1-i686-1se.txz [libraries]
- gtkmm-2.24.4-i486-1_msb > gtkmm-2.24.0-i686-2se.txz [libraries]
- gtksourceview-2.10.5-i486-1_msb > gtksourceview-3.7.2-i686-1se.txz [libraries]
- mm-common-0.9.6-noarch-1_msb > mm-common-0.9.5-i686-2se.txz [libraries]
- pangomm-2.34.0-i486-1_msb > pangomm-2.28.1-i686-2se.txz [libraries]
- libsigc++-2.2.11-i486-1_msb > libsigc++-2.2.10-i686-1se.txz [development]
Please be sure to use the Studioware packages instead.
FYI: Mate 1.6.2 seems to run fine with the Studioware-14.1 packages listed above.
Extra Options for sepkg/studiopkg/multilib
- /etc/sepkg/sepkg.conf can take any of the normal SlackBuild variables to change the default build locations etc.:
- TMP=/home/tmp/se
- OUTPUT=/home/tmp
- In a multilib install set where you need to build/install 32bit packages, or in a 32bit chroot on a multilib host:
- ARCH=i686 in /etc/sepkg/sepkg.conf
- ARCH=“” in /etc/studiopkg/studiopkg.conf
Java
- Either jdk or openjdk is a buildtime requirement when using sepkg to build the audio or full queue. jdk can be found in the extra/ directory on any of the slackware mirrors, or alienBob has packages for openjdk here: http://www.slackware.com/~alien/slackbuilds/openjdk/
RT Scheduling and Locked Memory
- Having problems with ulimit and locked memory?
- Put the line 'ulimit -l unlimited' (or whichever value you need) in /sbin/initscript.sample and copy it to /etc/initscript. Do not remove the exec line!
- Reboot required.
- Having problems with applications (ardour3 for example) failing to start jack with realtime scheduling?
- Add the line 'ulimit -r 65' to /etc/initscript as described above.
- Reboot required.
Kernel/Lilo
- Using the threadirqs kernel option (Please see http://wiki.linuxaudio.org/wiki/system_configuration#the_kernel)
- This is only needed for kernels that are not tweaked for lowlatency performance.
- Stock Slackware kernels can take advantage of adding 'append=“ threadirqs”' including the quotes to /etc/lilo.conf.
- To check any kernel config run the following command: 'grep -e CONFIG_IRQ_FORCED_THREADING -e CONFIG_PREEMPT=y /boot/[your kernel config]'.
- To check your current running kernel run this command: 'zgrep -e CONFIG_IRQ_FORCED_THREADING -e CONFIG_PREEMPT=y /proc/config.gz'.
- Add the 'threadirqs' boot option by editing /etc/lilo.conf and adding 'append=“ threadirqs”' including the quotes.
- Run Lilo 'lilo'.
- Reboot required.
Asoundrc
A carefully crafted ~/.asoundrc may be needed in some cases.
- Using an alsa only application through JACK
- You can try these guides for starters:
- Jack and Loopback device as Alsa-to-Jack: http://alsa.opensrc.org/Jack_and_Loopback_device_as_Alsa-to-Jack_bridge
- Using snd-aloop with JACK: http://gamesplusone.com/alsa_to_jack.html
