    unknow monitor & screen is not refreshed

    I installed Ubuntu 9.10 on an old PC, Dell dimension L550r, PIII500, 512M ram.

    There is a problem that monitor is not detected. I could logon as 'xterm' type, but the window size is only 1/4 of screen. When I logon as 'GNOME', it seems screen is not refreshed. media player window is blank, but can see a static image if minimize and restore window. Even terminal window is blank.

    Go to "System"->"Preference"->"Display", shows "monitor unknown"


    I can not find file /etc/X11/xorg.conf, is this normal?

    xrandr command output:
    Screen 0: minimum 640x400, current 1024x768, maximum 1024x768
    default connected 1024x768+0+0 0mm x0mm
    1024x768 60.0* 75.0 70
    832x624 75.0
    .....

    Any help is appreciated.

    Hi and Welcome !

    xorg.conf file is not available in Ubuntu by default and it uses generic values to configure Display.

    Which Graphics Card do you have?
    Try to create xorg.conf file manually.

    Generic contents of xorg.conf file:
    Code:
    Section "Device"
           Identifier "Configured Video Device"
           Driver    "vesa"  
    EndSection
    
    Section "Monitor"
             Identifier "Configured Monitor"
             HorizSync 31.5 - 70.0
             VertRefresh 50 - 160
     EndSection
    
    Section "Screen"
            Identifier "Default Screen"
            Monitor "Configured Monitor"
            Device "Configured Video Device"
            DefaultDepth 24
            Subsection "Display"
                 Depth 24
                 Modes "1280x1024" "1024x768" 
            EndSubsection
    EndSection

    You probably need to run X on framebuffer driver with this kind of hardware.

    Thank you for your reply. The graphics card is onboard Intel Corporation 82810E. Here is lspci output:

    After manually created the xorg.conf, I could make resolution 800x600 work, but refresh rate is still low.

    in xorg.conf, I set deriver = "vesa", is this correct? if I set to "i810" or "intel", xserver can not start and screen keeps flashing

    Section "Device"
    Identifier "Configured Video Device"
    Driver "vesa"
    EndSection

    I know the graphics card does support 1024x768 because It was 1024x768 in Windows.

    I read something about 915resolution. But, I can not install it because of this error.

    Error message:
    Package 915resolution is not available, but is referred to by another package.
    This may mean that the package is missing, has been obsoleted, or
    is only available from another source

    Is there any idea to fix the graphics card problem? Thanks!

    Have you check your Monitor's Manual? Refresh Rates play a major role in Display settings. Set supported Refresh Rates ( HorizSync and VertRefresh ) in xorg.conf file.

    AFAIk, 915resolution package is not available in sources and was removed in 9.04.

    Thank you for your reply.

    Monitor parameter is set correctly, but it does not change anything. I think it is related to graphics card driver.

    Here is the xrog.conf at use.

    Section "Device"
    Identifier "Intel Corporation 82810E DC-133 CGC [Chipset Graphics Controller]"
    Driver "vesa"
    BusID "PCI:00:01:0"
    EndSection

    Section "Monitor"
    Identifier "Configured Monitor"
    HorizSync 31.5 - 60
    VertRefresh 60 - 75
    DisplaySize 304 228
    Option "DPMS"
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Intel Corporation 82810E DC-133 CGC [Chipset Graphics Controller]"
    DefaultDepth 16
    Subsection "Display"
    Depth 16
    Modes "1024x768" "800x600" "640x480"
    EndSubsection
    EndSection
    Only "800x600", "640x480" are detected. But, in "System"->"Preference"->"Display", refresh rate is 0 Hz, and monitor is unknown.

    Do you have any idea?

    Rename existing xorg.conf file. Just copy and past contents of xorg.conf file from post #2. Do not edit any thing. Reboot machine.

    I have install 915resolution, but got this error
    Intel 800/900 Series VBIOS Hack : version 0.5.2

    Intel chipset detected. However, 915resolution was unable to determine the chipset type.

    Please report this problem to xxxx
    Any idea about this?

    Here is /var/log/Xorg.0.log if I set driver to "vesa". The best resolution is 800x600 16bit, or 1024x768 8bit. So, I think I have to update driver to get a better resolution.
