xfree86 config

crasspm · 03-24-2003, 03:55 AM

I'm very new to Linux. I'm running Red Hat 8, and while in my KDE desktop environment, I altered screen resolution to something my monitor can't handle (it can't display at anything over 1024x768). Upon restarting, I found I couldn't get to my desktop anymore, I can only access console mode. How can I change my resolution back within the console?

Thanks,
Peter

You can change this in the XF86Config file. iirc the file X on redhat uses is /etc/X11/XF86Config-4 (try locate if it isn't there).

search for something like:

Code:

    Subsection "Display"
        Depth       16
        Modes        "1280x1024" "1024x768" "800x600" "640x480"
        ViewPort    0 0
    EndSubsection

and change the Modes line to something your monitor can accomplish.

NOTE:
You can specify more than one mode as seen above, X will use the first one to start. Usually you can switch resoluction with <ctrl>+<alt>+KP_+ and <ctrl>+<alt>+KP_-

KP_* are the keys on the number block (is this the right term in english?.

[edit] added the note.
