Resolution problem Opensuse 11.1 KDE4+Nvidia

greets @all !

Is it possible to configure a resolution 1280x800 manually?
The used Nvidia Driver (Version 180.22) can only handle 1680x1050 or 1024x768 but never 1280x800 :frowning:
Sax2 can activate the resolution 1280x800 but the desktop fonts have less sharpness (-> because of missing NVidia parameters in xorg.conf?).
Using a mix between Nvidia and the sax2 xorg.conf, the display falls back to 1680x1050 :ā€™( ā†’ even though there is no entry of this resolution in xorg.confā€¦

We are using a GeForce 9500GT grafic card with a Samsung SyncMaster 205BW monitor.

Does somebody have an idea ?

Best regards !

Open a console (in the GUI desktop; donā€™t use CTRL-ALT-F? to get a virtual text terminal). ā€œsuā€ to become root, then enter ā€œnvidia-settings.ā€ Hopefully, this was installed with your driver. If so, it should allow you to set the resolution you want.

nvidia-config is installed, but there is no choice for resolution 1280x800 (which should be the best for our needs). Only 1280x960 or 1280x1024 is availableā€¦

OK, from what I understand: thereā€™s a problem with the driver sometimes misinterpreting EDID specs reported by the monitor. (Or, maybe the monitor reports them incorrectly; Iā€™ve seen both on the Web.)

At any rate, your monitor isnā€™t reporting that resolution to the driver in a form that it can understand. The solution is to manually add a modeline to your xorg.conf file.

Iā€™ve got to hit the road, maybe someone else here can pitch in with the standard links to ā€œhow to do a modelineā€ and all that. :slight_smile:

Thanks for the hint :slight_smile:
But all test with xorg.conf failed. We put the resolution to the file and restart X - but the Nvidia drivers fall back automatically to 1280x1024 instead of 1280x800 ?!

Solved ! After installing KDE 4.2 the systemparamters are available again and we can modify all necessary options. :wink:
