    Fedora help on screen resolution


    I have FC 4 on a Gateway PC with an 17" monitor I tried to change my
    screen res from GUI and now when FC boots it turn my monitor off.
    I was able to get back to root. Is there a file that I need to config
    to get my monitor working again ? Thanks

    hi dylan1234,

    Welcome to the LinuxForums.

    log in as root in command line mode and execute 'system-config-display' command. configure resolution and video driver. if your Monitor is not listed in Monitor's list, select 'Generic' Monitor.

    Graphics is configured by /etc/X11/xorg,conf file, you can edit that file manually too but try 'system-config-display' command first.

    whats the output of startx command?
    if startx throws error too, edit xorg.conf file manually.
    Code:
    nano /etc/X11/xorg.conf
    set Video Driver to "vesa"
    Code:
    Section "Device"
    	Identifier  "Videocard0"
    	Driver      "vesa"
    EndSection
    in case, it doesn't work, post the Screen and Monitor sections here.

    The ' start X ' command turned off the monitor quickly and then it stopped after :

    (==) Using configfile: " /etc/X11/xorg.conf"

    I used CTRL-Z and ended it.

    I did run ' nano /etc/X11/xorg.conf ' and found the following:

    Section "Monitor"
    identifier "Monitor 0"
    vendor name "Montior Vendor"
    model name "GWY7658"
    display size 330 240
    horizSync 30.0 - 70.0
    vert refresh 50.0 - 120.0
    option "dpms"
    end section

    Section "Device"
    identifier "Videocard 0"
    driver "NV"
    vendor name "videocard vendor"
    boardname "Riva Tntz"
    end section

    * These are the two sections I found for the monitor. If I change the
    driver would I just need to select X for exit and would the settings be saved
    and then try to reboot ? When this first happened my GUI screen was half the size of my monitor screen. I went to the tool bar and selected display and choose another setting larger and it re-booted and now it turns off the monitor when booting up.

    - Thanks

    change "NV" driver to "vesa", save file ( press Ctrl+X, y and Enter key to save file ) and execute 'system-config-display' command. execute 'startx' to check GUI. no need to reboot.

    I also have this computer setup as a dual boot for FC4 and Win2000 with Oracle10g installed on both. When I set this up I had help and we had trouble with finding a driver for FC 4 and the monitor GATEWAY2000 CrystalScan 17"
    It is an older model monitor and I may be getting a new monitor for this in the future.

    It was working good but my Oracle EM interface is very large compared to on the Win2000. Do I need to find the a driver for FC 4 and this monitor so my EM is the normal size ?

    -Thanks

    do you know correct HorizSync and VertiRefresh rates supported by that Monitor?
    Refresh rates make a lot of difference. set correct rates in Monitor Section of xorg.conf file.
    "vesa" is a generic driver and it works for all types of Graphics Cards and Monitors.
