 |
|
i have an ati radeon 4870 and am using ati-drivers-8.582.
i want to run at my 24" LCD's native resolution of 1920x1200.
below is my xorg.conf file and it specifies a single resolution of 1920x1200. but for some reason i can only run at 1400x1050 as shown by the xrandr output. where did it get the 1400x1050 res anyways? i didn't even specify that anywhere.

don't set this:
Option "UseEdidDpi" "false"
Option "DPI" "96 x 96"
and don't set any Modes.

Does it work yet?
Try this
| Code: | xrandr --addmode DFP1 1920x1200
xrandr --output DFP1 --mode 1920x1200 |
It did the trick for me with intel 945 and a 22" screen. |
