This will follow the steps involved in setting up ArchLinux on a Compal CL56/CL56P Laptop. This is a very common base laptop system that is rebranded by a lot of different companies. This is specifically going to be about the steps needed for a Velocity Micro B51 Campus Edition working fully. There is a linux-laptop.net page: [1] for the CL56, as well as another page here: [2] also for the CL56.

This will follow all the special things I have had to do and anything new that I come across as it happens. Out of the 'box' as it were Arch works decently.

  • Wireless (Intel Pro Wireless 2200BG)
    • The ipw2200 driver to make it work is included in the kernel, the card supports managed, ad-hoc and monitor modes.
    • The wifi switch needs the acerhk module: its source is available at [3], but a PKGBUILD is available on the AUR.
    • After compiling the module, it needs to be added to the MODULES array in /etc/rc.conf. The AUR build includes a daemon that activates the module, to have it started at boot time add it to the DAEMONS array in /etc/rc.conf.
  • SD (Secure Digital) card reader/writer
    • It is physically located just underneath the CardBus slot.
    • MMC read/write support works with mmc_block driver.
    • Add mnt/mmc directory and the following line to /etc/fstab
/dev/mmcblk0p1 /mnt/mmc vfat rw,user,auto,exec,sync 0 0 
  • Sound
    • After loading the snd_intel8x0 module the card works without problems.
  • ATI Radeon
    • just follow Ati Radeon & Kernel 2.6
    • use X.org and just download the proper driver from ATI homepage
    • performance is is about 2100 fps with glxgears and 410 fps with fgl_glxgears if drivers are installed correctly
  • VGA Dual Monitor Head Output/S-Video output
    • works, just use the configuration application included with ATI drivers
  • PCMCIA
    • works with standard kernel, just add the following line to /etc/rc.local
cardmgr
  • Infrared
    • add irda ircomm ircomm-tty to /etc/rc.conf MODULES list.
    • for using GPRS over IR add the following line to /etc/rc.local
mknod /dev/ppp c 108 0

and use pppconfig to configure the connection settings (use /dev/ttyS0 as the port)

Power Saving Tips

Load the OnDemand Governor at boot time, add the following to /etc/rc.sysinit

status "Setting CpuFreq Governor to OnDemand"
echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
