Display problem or something

Grooveyphreak · 05-27-2005, 02:10 AM

Okay after about 3 or 4 times trying to install two versions of linux with moderate luck i finally sort of figured it out i had to install RH9 in lowres mode and cannot move the resolution from 640X860 i think which is odd due to the fact that winxp can go as high as the intergrated graphics can i'm sure this may be just a driver problem but kudzu detects all my display stuff monitor card etc. but when i change the resolution to 800X600 my monitor comes up with this out of frequency range message and i can't get into graphical mode so how do i change back to 640X860 in text mode. i'm very new to linux so please help me with this.

You might need to post some system specs for someone to be able to assist.

Also you should have a look in the /etc/X11 directory and see if you have either an XFree86.conf or an Xorg.conf file which would look a bit like this

Code:

Section "Files"
    # Multiple FontPath entries are allowed (they are concatenated together)
    # By default, Mandrake 6.0 and later now use a font server independent of
    # the X server to render fonts.
    FontPath "unix/:-1"
EndSection

Section "ServerFlags"
    #DontZap # disable <Crtl><Alt><BS> (server abort)
    #DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)
    AllowMouseOpenFail # allows the server to start up even if the mouse does not work
EndSection

Section "Module"
    Load "dbe" # Double-Buffering Extension
    Load "v4l" # Video for Linux
    Load "extmod"
    Load "type1"
    Load "freetype"
    Load "glx" # 3D layer
EndSection

Section "InputDevice"
    Identifier "Keyboard1"
    Driver "keyboard"
    Option "XkbModel" "pc105"
    Option "XkbLayout" "gb"
    Option "XkbOptions" "compose:rwin"
EndSection

Section "InputDevice"
    Identifier "Mouse1"
    Driver "mouse"
    Option "Protocol" "ExplorerPS/2"
    Option "Device" "/dev/mouse"
    Option "ZAxisMapping" "6 7"
EndSection

Section "Monitor"
    Identifier "monitor1"
    VendorName "Generic"
    ModelName "1280x1024 @ 74 Hz"
    HorizSync 31.5-79.0
    VertRefresh 50-90
EndSection

Section "Device"
    Identifier "device1"
    VendorName "nVidia Corp."
    BoardName "NVIDIA GeForce4 (generic)"
    Driver "nvidia"
    Option "DPMS"
EndSection

Section "Screen"
    Identifier "screen1"
    Device "device1"
    Monitor "monitor1"
    DefaultColorDepth 24
    
    Subsection "Display"
        Depth 8
        Virtual 1280 1024
    EndSubsection
    
    Subsection "Display"
        Depth 15
        Virtual 1280 1024
    EndSubsection
    
    Subsection "Display"
        Depth 16
        Virtual 1280 1024
    EndSubsection
    
    Subsection "Display"
        Depth 24
        Virtual 1280 1024
    EndSubsection
EndSection

Section "ServerLayout"
    Identifier "layout1"
    InputDevice "Keyboard1" "CoreKeyboard"
    InputDevice "Mouse1" "CorePointer"
    Screen "screen1"
EndSection

When you know which you have (which tells you which X server your system is using), you should then look at the /var/log/xorg.0.log (or /var/log/XFree86.0.log or something vvv similar to that), you'll probably have to be root to look at it (I won't post and example, it's often rather long), but you should be looking for lines that start with (EE), those are the errors that might give you/someone an idea of what is going wrong with your system.

Sorry I can't be of more help, but I don't know a lot about linux really, I've just got a bit of an idea where to start looking for display problems!
