Ubuntu 7.04, Feisty
Ubuntu 7.04 (Feisty) Just Works on the X22.
DRI
By default in the section of your screen, the DefaultDepth is 24 but X22 don't have enough video memory to enable this setting, change it to 16 and DRI will be ok. You just double your FPS under glxgears :D
Power saving
Reporting by powertop, gnome is not so good for battery life and ibm_acpi neither, maybe you have to choose between comfort and some shortcuts ...

Ubuntu 5.10, Breezy
Ubuntu 5.10 (Breezy) has problems with suspend to disk (hibernate) and suspend to ram (sleep) on the X22.
Suspend
However, Software Suspend 2 works well, and is fast enough to be a useful replacement for sleep. The following howto explains the installation process: http://ubuntuforums.org/showthread.php?t=75443
NOTE: during kernel configuration, in device drivers -> ata be sure to say N to 'generic/default IDE chipset support', and Y to 'Intel PIIXn chipsets support'. This will allow for much faster suspend.
To enable suspend by pressing FnF12 (instead of the power button recommended in the howto), edit /etc/acpi/events/ibm-hibernatebtn and change the action line to read
action=/usr/sbin/hibernate
Ubuntu 5.04, Hoary
Ubuntu 5.04 (Hoary) Just Works on the X22.
ACPI
However, ACPI suspend to ram is disabled by default. To enable it, edit /etc/default/acpi-support and uncomment the line
ACPI_SLEEP=true
This will allow suspend by pressing FnF4
By default, closing the lid blanks the screen, but does not suspend. To suspend on lid close, edit
/etc/acpi/events/lidbtn and change the action line to read
action=/etc/acpi/sleep.sh
