My Linux Fedora 12 system became very slow. Xorg uses  100% of CPU,  so that system also boots very slow. Please help!

    Sreenivas,

    did Artur’s suggestion fix your problem?

  • Artur Wrona

    Add the below option to /etc/X11/xorg.conf under the Device section.

    ———————–
    Option “UseEvents” “on”
    ———————–

    Below shows how this change will look under the Device section.

    Section “Device”
    Identifier “Videocard0”
    Driver “nvidia”
    VendorName “NVIDIA Corporation”
    BoardName “GeForce FX 5200”
    Option “RenderAccel” “on”
    Option “UseEvents” “on”
    EndSection

    It will change the way drivers are communicating with kernel when waiting for other hardware. Usually solves problem with high CPU usage on nVidia cards, but might result in little unstable work. If your Xorg will start crashing, just delete this line.
