    Display problems on Dell Inspirion 1100


    I have installed Mandrake 9.1 on my dell inspiron everything works well except for the display which defaults at 640*480 even though I have specified 1024*768, and I cannot change the resolution. Here are the relevant specs:

    Dell 1024 Flat Panel Display
    Intel 845 Graphics Board

    Here is my XF86Config-4 file [I have only added one line, the one in the card sector specifing the videoram everything else is untouched]

    # File generated by XFdrake.

    # Refer to the XF86Config man page for details about the format of
    # this file.

    # 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)

    Thank you for taking the time to help. I appreciate it.

    change this
    Code:
    Subsection "Display" 
    Depth 8 
    Modes "1024x768" "800x600" "640x480" 
    EndSubsection 
    
    Subsection "Display" 
    Depth 15 
    Modes "1024x768" "800x600" "640x480" 
    EndSubsection 
    
    Subsection "Display" 
    Depth 16 
    Modes "1024x768" "800x600" "640x480" 
    EndSubsection 
    
    Subsection "Display" 
    Depth 24 
    Modes "1024x768" "800x600" "640x480" 
    EndSubsection 
    EndSection
    to this

    Code:
    Subsection "Display" 
    Depth 8 
    Modes "1024x768"
    EndSubsection 
    
    Subsection "Display" 
    Depth 15 
    Modes "1024x768"
    EndSubsection 
    
    Subsection "Display" 
    Depth 16 
    Modes "1024x768"
    EndSubsection 
    
    Subsection "Display" 
    Depth 24 
    Modes "1024x768"
    EndSubsection 
    EndSection

    also remember, that once in X you can change the resolution by pressing <Crtl><Alt><KP_+>/<KP_->

    Thank you. I did as you said but the problem remains. Is there something else that I should try?

    I believe the file /var/log/XFree86.0.log is necessary to solve this. However, it's too large to post here, so mail it to me instead and I will put it up on my HTTP server for everyone to see.
