Configuring Ubuntu 11.04 to run with the highest VGA resolution on i915

After the i915 configuration my screens did not use the 1920x1080 resolution that my monitor is capable of. Neither did it select VGA1 as input :(

# xrandr

reports LVDS1 at 1280x1024 as default display, editing my xorg.conf didn't seem ti fix the issue? Guess I edited it wrong!

There's two tweaks that need to be created, firstly I disabled LVDS1 and forced VGA1 as the default video device at boot Append:

video=LVDS-1:d video=VGA-1:e

to your kernel boot parameters in /etc/default/grub


Mine looks like this now:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash video=LVDS-1:d video=VGA-1:e acpi=force elevator=noop i8042.noloop=1 usbhid.quirks=0xeef:0x1:0x40"

Next, force gdm to use the resolution at login, by adding:

xrandr --output VGA1 --mode1920x1080 --rate 60

to  /etc/gdm/Init/Default

The xrandr command does ofcource depend on your monitor and graphics device. You cn alwasy type xrandr to see it's capabilities. See man xrandr for details.
