    Question 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
    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 -> even though there is no entry of this resolution in xorg.conf.....

    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; don't use CTRL-ALT-F? to get a virtual text terminal). "su" to become root, then enter "nvidia-settings." 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 available...

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

    At any rate, your monitor isn'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.

    I've got to hit the road, maybe someone else here can pitch in with the standard links to "how to do a modeline" and all that.

    Thanks for the hint :-)
    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 ?!

    Thumbs up Re: Resolution problem Opensuse 11.1 KDE4+Nvidia

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