Current x.org versions should be able to auto-detect the VertRefresh |
| 17 |
and HorizSync settings, as well as appropriate modelines. So I would |
| 18 |
comment out all such stuff from your xorg.conf file, and see if the |
| 19 |
autodetection will work. |
| 20 |
|
| 21 |
Probably the easiest way to do this will be: |
| 22 |
|
| 23 |
mv /etc/X11/xorg.conf /etc/X11/xorg.conf.save |
| 24 |
X -configure |
| 25 |
(follow the printed instructions for testing the generated config) |
| 26 |
mv <path from X -configure> /etc/X11/xorg.conf |
| 27 |
|
| 28 |
You may have to change /dev/mouse to /dev/input/mice in the generated |
| 29 |
config before it will work. |
| 30 |
|
| 31 |
Then you can diff the generated config with your old one, and see what |
| 32 |
settings you want/need to keep. |
