           Summary: X locks up when running compiz on cloned screen with

          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

Sorry for this very vague report, I'm happy to provide any more info you might
need.

I run xserver 1.3 with the ATI driver 6.7.195, on a M22 (X300), on a thinkpad
T43.
I use XAA and AIGLX.

When running compiz on a single display (LVDS), it works fine. However when I
run it when 2 monitors are connected, it runs for a few seconds, then always
ends up locking up the system after a few operations on windows.
