Description Jakub Hrozek 2007-09-26 09:19:20 EDT
Description of problem:
I have a ThinkPad R61 with an Intel X3100 driver. After start, rhgb, gdm and 
de itself are not rendered on the whole screen as 1024x768 resolution is 
selected (native is 1440x960). You can move the mouse pointer over whole 
screen, but panels, windows etc are rendered in upper-left hand corner only.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. grab a thinkpad with a 3100 intel card (R61 and T61 are affected for sure)
2. start system with rhgb or boot into runlevel 5
3. DE/gdm not rendered correctly
Actual results:
wrong resulution selected

Expected results:
the correct resulution selected

Additional info:
There is a workaround proposed by someone of fedoraforum.org. The root cause 
is TV output being on, as one can see with xrandr -q. Disabling the TV output 
with the following lines does the trick for me:

Section "Monitor"
        Identifier   "TVOutput"
        Option       "Disable" "true"

and also adding this to the videocard "Device" section:
Option      "monitor-TV" "TVOutput"
