No special procedure required during installation

This laptop is operating under Kernel version 2.6.24-16

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. After installing the driver and adding those lines to the xorg.conf, the basic desktop effects should work, but due to the high screen resolution and slow video card, the full effects (especially the desktop cube-switch) will be extremely choppy.

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.
