Why does Xorg use 100% of CPU power in Linux Fedora 12?

sreenivas June 10, 2010

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

    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"

    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.
