Monitor / xorg problems

Gortex · 04-17-2008, 09:29 PM

I just went to staples and purchased a 22" wide screen monitor for my pc. I brought it home and tried to get it to accept 1650 x 1050 resolution in ubunto 7.10. Windows accepts this just fine and the monitor works as it should. In ubunto though It wont accept it, in fact now I can not log in because what is being displayed on the log in is a bunch of grabge lines more then likely some refresh rate or resolution that is not intended for the monitor. any help on getting linux to display properly ?

ubunto 7.10
Radeon 9800 ST
Envision G2219w1

Okay I got xorg up and running, but I still can not get any of the wide screen resolutions to work

.
I end up with about two maybe three inches cut off on the left side of my moniter.
Linux is running really slow now as well, I cant turn on any of the desktop effects
and open a simple pdf takes about two minutes.

First, what driver is specified in /etc/X11/xorg.conf? (Look for an entry similar to this:

Code:

Section "Device"
    Identifier "device1"
    VendorName "ATI Technologies Inc."
    BoardName "ATI Radeon"
    Driver "radeon"
EndSection

I have found that I sometimes need to use a modeline to get wide-screen monitors to work correctly. Use the "gtf" command to generate the modeline, then put it in the "Display" section. Make sure that the mode entry in the "Screen" section has the same name as the modeline.
