Comment 10 for bug 196617

Have installed ATI 8.4 drivers, and running Xinerama-based dual head on ATI Radeon Mobility X1300, hardy beta 5, AMD 64.

I now have the "log noise" problem; keeps repeating:

...
(EE) fglrx(1): [DRI] Unlocking inconsistency:
        Context 9124404 trying to unlock lock held by context 2
(EE) fglrx(1): [DRI] Locking deadlock.
        Already locked with context 9124404,
        trying to lock with context 2.
...

And: OpenGL blocks. For instance, if I run glxinfo, it stops after printing the first line of output:
jorgen@brain:~$ glxinfo
name of display: :0.0

The screensaver setup utility also stops on launch. (I have an OpenGL screensaver selected.)
