@Dan
Thanks for the reply. I'm using Ubuntu Karmic with kubuntu-desktop installed
on top.
I bricked my first timeline on a BIOS downgrade so I'm not feeling too bold
on trying an upgrade. My BIOS (for the 4810t) is 1.10.

@Thomas
Add the following to the GRUB_CMD_LINUX_DEFAULT entry in /etc/default/grub:
nomodeset acpi_backlight=vendor

and then run sudo update-grub on the terminal.

This fixed it all in gnome for me and others.
