Gateway T-6345U and Ubuntu Lucid

on

Well We are now around to Ubutu Lucid Lynx (10.04) and it looks like nothing has changed support wise, so to get the backlight to adjust, just add:

[bash]nomodeset acpi_backlight=vendor[/bash]

to the “GRUB_CMDLINE_LINUX_DEFAULT” section, right after “quiet splash” and before the closing quotation mark. Now run

[bash]sudo update-grub[/bash]

and you will be good to go! Reboot and try out your freshly brewed screen backlight adjustments!
