    Openchrome Driver Freezes My Computer!

    hi there.....

    i have bought new motherboard ECS P4900-M2 with an inbuilt VGA card through Chrome 9, and has successfully installed Fedora Core 9 operating system.

    And now the problem arises here as when GUI starts with the help of openchrome driver from fedora core 9 operating system, I am unable to use it because it makes my computer freeze or hang.

    after I made change it into vesa GUI interface, it stared running smothly.

    I don't know what is the problem or the lacking part in this............

    Please help me to fix this ............

    add the following line to device section:

    The Device section of your xorg.conf should look to something like that :
    Section "Device"
    Identifier "Videocard0"
    Driver "openchrome"
    Option "AccelMethod" "EXA"
    EndSection

    if it still doesn't work, try with :
    Section "Device"
    Identifier "Videocard0"
    Driver "openchrome"
    Option "NoAccel"
    EndSection

    Adding the following line to the Device section of the xorg.conf fix the
    issue:

    Option "AccelMethod" "EXA"

    Option "AccelMethod" "EXA"
    Option "ExaNoComposite" "True"
    Option "MigrationHeuristic" "greedy"
    Option "ExaScratchSize" "8192"
    Option "MaxDRIMem" "16384"

    I believe some non-EXA problems are avoided with;
    Option "SWCursor" "true"
    Option "NoXVDMA" "true"

    From some tests I also have still active this;
    Section "Extensions"
    Option "Composite" "enable"
    EndSection
