    Fedora Display Problems

    I think this fits (and yes I'm new to Linux )

    I installed Fedora Core onto my desktop, and the screen area is larger than what is being displayed (basically it seems to be running 1024x768 but the monitor is only displaying 640x480) so that when I move the mouse to the edge of what is show the display scrolls to the edge. I have tried changing the display and screen resolution preferences to any combination I can come up with (and if I change it all to 640x480 it does display properly).

    I have an ATI Radeon 7000 and the monitor is a CTX Flat Panel (Model PV720A).

    Any suggestions or ideas?

    If more information would be helpful please tell me what you need and, quite possible, how to get that information.

    is the monitor thing set to flat panel, and can u post ur /etc/X11/XF86config file

  3. #3
    The monitor is actually recgnized exactly as itself (or at least Fedora shows it being recognized correctly in the display section of system settings).

    I'm not at the PC atm, so I'll have to post the file shortly (a little later today).

    Thanks for the CTRL + ALT + +/- tip, but that didn't do it either.

    Here is my XF86cofig file:

    # RgbPath is the location of the RGB database. Note, this is the name of the
    # file minus the extension (like ".txt" or ".db"). There is normally
    # no need to change the default.

    # Multiple FontPath entries are allowed (they are concatenated together)
    # By default, Red Hat 6.0 and later now use a font server independent of
    # the X server to render fonts.

    # Option "XkbModel" "microsoft"
    # Then to change the language, change the Layout setting.

    # Option "XkbLayout" "de"
    # Option "XkbVariant" "nodeadkeys"

    Also, another update. When I log out the screen becomes "squirly" where the mouse only stays on the left hand side of the screen, and the screen seems tiled (almost like it is showing the four desktops) but this is at the login screen.

    Also, if I log out a second time after this, then the screen goes black and will not come up.

    the resolution thing happened to me im pretty sure it has nothing to do with the video card

    i fixed it by simply upgrading the the lastest version of xfree86 (4.4.0)and then running the setup
