    Red face No Background

    My background has changed to all black. I've tried changing it, and my choice shows for a few minutes and then disappears and I'm back to a black screen again. My icons all show, but it is rather disappointing not to get a background.

    Can anyone help me get my background back.

    I imagine you have compiz running and a resolution above 1024x768 and have an ATI graphic card using the default /ati/radeon driver that came with the install.

    You can workaround the problem by either turning of compiz (Alt+F2 and type metacity --replace in the box) or by running at a lower resolution, or by using 16 bit colour, which is what I did.

    The easiest is obviously to not use compiz, but I still found that graphics were slow on my ATI 9200SE card unless I used the 16 bit colour option.

    here's the config part of /etc/X11/xorg.conf that I used in my machine. Try an edit to your hardware resolution etc etc and see if it works for you.
    Code:
    Section "Device"
        Identifier     "Configured Video Device"
        Driver         "ati"
        Option         "AccelMethod" "UXA"
    EndSection 
    
    Section "Monitor"
        Identifier    "Configured Monitor"
                HorizSync    30-80
                VertRefresh    50-75
    EndSection
    
    Section "Screen"
        Identifier    "Default Screen"
        Monitor        "Configured Monitor"
        Device        "Configured Video Device"
        DefaultDepth    16
        SubSection "Display"
            Modes        "1280x1024" "1280x960" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
    EndSection
    Things are better in 10.04 and even better in 10.10, but there are possible other problems there depending on hardware. For me, 10.04 is the best yet, once I have the xorg.conf sorted properly.

    I do have an ATI Card but I only run at 1024 x 768. How do I change my screen to 16 bit resolution.

    Incidentally try Ubuntu 10 from a DVD I had no problem with background. I expect the obvious thing is to upgrade.

    Hi

    How do I change my screen to 16 bit resolution.
    Code:

        Device        "Configured Video Device"
        DefaultDepth    16
        SubSection "Display"
            Modes        "1280x1024" "1280x960" "1152x864" "1024x768" "832x624" "800x600" "720x400" "640x480"

    Try this:

    Press Alt+F2, and type in gconf-editor (or run from the terminal)

    Look at my screen shot, and navigate to that subfolder
    [ desktop > gnome > background ]

    Check to see if draw_background is checked.

    If not, check it.
