    originally posted this in the Acer forum, but it's probably better off here.

    original thread:
    http://forum.notebookreview.com/showthread.php?t=92527

    If I run 2D apps (like pinball, or some educational games for my kids) in fullscreen mode:

    1. the app will appear fine until I switch back to normal windows, then display is corrupted. for instance pressing F4 to switch to fullscreen in pinball then pressing it again to swtich back to windowed mode.
    OR
    2. the display is corrupted straight away.

    the display is cross-crossed like blue/black tartan!!

    The only way to rectify this is to close the lid, go into sleep mode and open the lid again and press space bar to wake it up again and all is fine again.

    I've tried ATI drivers (modded with dh_mod), Omega drivers no effect. Is this a lcd issue rather than vga drivers? I've tried switching to "no acceleration" in the vga drivers. this had no effect either. I've tried updating Directx too with the oct 2006 redist package.

    BTW, 3D apps like Half-life2 DeathMatch run fine.

    any ideas?

    many thanks in advance.

    specs:

    Acer Aspire 5024WLMi
    ATI x700 mobility 128MB (currently latest omega driver, based on Cat 6.9)
    512MB RAM
    Windows XP Home spk2
    directx 9.0c (Oct '06).

    have tried re-installing the chipset drivers for your laptop`s motherboard, specificaly the agp ones, these are separate from the ati drivers.

    good luck.

    IIRC Acer don't provide any AGP drivers as such.

    The Mobo chipset as reported by CPU-Z (1.32):

    Manufacturer: Acer
    Model: Aspire 5020
    Chipset: ATI RS482
    Southbridge: ATI SB400

    Graphic Interface
    version: PCI-Express
    Link Width: x16

    PCI-Express not AGP. I guess I should find the ATI chipset drivers???

    Problem resolved by restoring the original install from Acer CDs. that'll teach me not to meddle with GFX drivers.
