    Question [SOLVED] Screen artifacts when running VirtualBox


    When the VirtualBox guest OS (WinXP) is started, the other desktop screens behave strangely.
    It is difficult to describe how the issue looks like. Therefore, I have made a screenshot.


    Has anyone seen something like this before?
    Does anyone know why is this happening and how to fix it?

    Two questions.

    1. Have you installed the VirtualBox Guest Additions to the guest OS?
    2. You mention 2 different bits of hardware with different processors and video boards. Which are you running, and what video driver are you using?

    1. Yes, I have installed Guest Additions in the guest OS.
    2. VirtualBox is running on following hardware:
    • brand/model = HP Compaq DC7100
    • processor = Intel Pentium 4 Processor 541
    • video adapter = Intel 915G Express


    The guest OS has a bit of history. The guest OS (together with Guest Additions) is originally installed within the openSUSE 11.0 host on this very hardware. I've been using it for about 1/2 year without problems. Then I installed Fedora 12 on this hardware. Guest OS functioned fine within Fedora 12 host for about 8 months. Recently I installed Fedora 13 on this hardware, ever since there is a problem when I start VirtualBox.
    The guest OS operates perfectly, no problems there. However, the host OS desktop becomes messed up, can't use it in parallel with guest OS. Also after the guest OS shutdown, host OS desktop stays messed up (in fact unusable) until the host OS is rebooted.

    Ok. What I suggest is this.

    1. Update VirtualBox. If already uptodate, then uninstall/reinstall - this will not cause you to lose your VM's. They will be there after you reinstall VBox.
    2. Reinstall Guest Additions if you only updated VBox.
    3. Reboot
    4. See what happens.

    Also, are you running the open or commercial version of VBox?

    Thumbs up

    Rubberman, thanks for the suggestions.
    The issue is solved. Let me explain what I did.

    By the way, it is OSE release.

    Both VitualBox-OSE and kmod-VirtualBox-OSE were already updated.
    I have reinstalled Guest Additions (good suggestion!) as it was a very old release, but this didn't solve the issue.

    However, I remembered that about two weeks ago due to some memory problems I had to remove 1GB faulty memory from my machine. Still, I forgot to change the base memory allocation in the VirtulaBox settings (stupid mistake). As a result 760MB was allocated for the VirtualBox on a 1GM machine.

    After reducing the VirtualBox base memory to 440MB, the host desktop behaves normally again.
    So I believe this issue is solved now.
