Kubuntu 11.04 on the Chembook 2370VA

kubuntu-copiaMy experience with Fedora 15 was not as I had hoped. The ATI graphics driver was particularly problematic (regular minute-long hangs due to spinlock issues) so I decided to try a completely different distribution. I decided to go with Kubuntu 11.04 and performance has been excellent.


Basic installation

Just like the previous Fedora 15 installation, I ran a final backup of my data to an external USB drive, and then performed a full installation from the Kubuntu 11.04 DVD. I didn’t bother encrypting the hard drive as my laptop rarely leaves home now.
Once the installation completed, the first thing I did was to restore my data to the laptop.

Dual head set-up

I still had some issues getting my dual-head set up configured to my liking. As with FC15 I used a simply X11 script which runs automatically during boot.

cat /etc/X11/Xsession.d/45custom_xrandr
# Force the screen to a resolution my Compaq Q2159 supports -- but only if it
# is connected.
/usr/bin/xrandr | grep "$EXTERNAL_OUTPUT connected"
if [ $? -eq 0 ]; then
/usr/bin/xrandr --output $INTERNAL_OUTPUT --same-as $EXTERNAL_OUTPUT
/usr/bin/xrandr --output $INTERNAL_OUTPUT --off
/usr/bin/xrandr --output $EXTERNAL_OUTPUT --mode $MODE --rate $RATE

This script detects if my Compaq monitor is connected, and if it is, disables the screen of the laptop.

Configuration Files

I rebuilt the kernel — the configuration file is here.
