Xorg log
Just recently updated my system from Xubuntu 12.04LTS with fglrx driver to
Xubuntu 12.10 with Xorg radeon driver. After bootup screen goes black with
monitor reporting "Input not supported". Further investigation shows KMS is
trying to default the resolution to 1400 x 1050 which is not supported by the
monitor. I can switch to the terminal and run this command to force the correct
resolution:
XAUTHORITY=/var/run/lightdm/root/\:0 xrandr --output DVI-0 --mode "1440x900" -d
:0.0
Rebooting the system results in the same scenario above.
