[solved] Tearing Problem / Refresh Rate

Hey,

i have a huge tearing problem. Watching movies is a real torture.

I think it's the refresh rate. The recommended refresh rate for my display is 60Hz (@1920x1080p). But i can only choose 50Hz in the XFCE settings (link).

Anyone can say how to change this to 60Hz? If any configs or hardware specifications are needed, please let me know.

What video card do you have? If it's a nvidia card check what the refresh rate is in nvidia-settings (maybe similar thing for ATi). Check to see if your xorg.conf settings are correct for your monitor.

It's a nvidia 8800 GTS.

If I choose Resolution: Auto in nvidia-settings I can only use Refresh Rate: 50Hz in XFCE settings.
If I choose Resolution: 1920x1080 60Hz in nvidia-settings I can use Refresh Rate: 50Hz or 122Hz in XFCE settings.

Here the monitor part of xorg.conf:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "AOC 2795E"
    HorizSync       30.0 - 83.0
    VertRefresh     55.0 - 75.0
    Option         "DPMS"
EndSection

Sync to VBlank is always enabled in nvidia-settings.

But tearing anyway...

You have to disable composite extension in Xorg.

Add, this, to the end of the /etc/X11/xorg.conf.

Section "Extensions"
        Option  "Composite" "Disable"
EndSection

And ofcourse reboot the system.
