This laptop is operating under Kernel version 2.6.28-11

Notes:

If you install the nvidia driver, see Xorg.conf at bottom of page and add the bolded lines into your xorg.conf BEFORE REBOOTING, otherwise the laptop will only display video through the external monitor port. If you do (or did) reboot before adding those lines, switch to another virtual console (ctrl-alt-F1) and type sudo nano -w /etc/X11/xorg.conf. Add those lines to the appropriate place, then save and exit (ctrl-O,ctrl-X) then reboot. That should fix the display problems. For reasons I have not yet determined, using nvidia-xconfig causes X to crash on the next reboot. The drivers install correctly as far as I can tell, but the nvidia-xconfig package does not use the right xorg.conf settings. Hopefully this is only because it is an alpha release and the problem will be fixed in the final release.

install i8kutils then modprobe i8k to control fans and monitor temperature

the fn keys work for changing the volume and brightness/contrast with no special configuration.
