DRM modules is kernel drm instead of libdrm. libdrm2.4.1 is OK. Maybe you can try on the latest drm module in kernel.

> Maybe you can try on the latest drm module in kernel.

I don't mind to update it, but I could not find opensuse package in which it is located - is it somewhere in X11 repository (http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_11.0/x86_64/) or is it in kernel main package (kernel-default) or is it somewhere else?

My current kernel version is 2.6.25.18-0.2-default - with latest updates available from package manager.

You can download the latest kernel from http://www.kernel.org/

Looks like the kernel delayed vblank swap bug that was fixed in the kernel back in July.  Disable vblank synchronization in driconf to confirm.

How can I do this? I have DRI section in xorg.conf file, but no vblank parameters in it or anywhere else


Section "DRI"
    Group      "video"
    Mode       0660
EndSection

Try this
set vblank_mode to 0 in your ~/.drirc, such as 

<driconf>
 <device screen="0" driver="i965">
         <application name="Default">
                 <option name="vblank_mode" value="0" />
         </application>
 </device>
</driconf>

This helped! Thanks

Bug was fixed in the kernel this summer, and we deleted the fixed offending code for 2.6.28.
