Comment 1 Jamey Sharp 2006-12-19 16:40:15 UTC

I believe this is a duplicate of bug #8581. If upgrading to libXi 1.1.0 doesn't
fix the problem for you, please re-open this bug.

*** This bug has been marked as a duplicate of 8581 ***

Comment 2 Stefan Dirsch 2006-12-19 20:17:42 UTC

Thanks. I'll verify with libXi 1.0.2 + git patches:

- Don't call XInput_find_display in _XiGetExtensionVersion, while the Display 
  lock is held. (2006-10-15 09:03:57)
- Bug #8663: _XiCheckExtInit must drop the Display lock in all error cases.
  (2006-11-19 10:04:26)

The patch

- Don't call XInput_find_display in _XiCheckExtInit, while the Display lock
  is held. (2006-10-15 06:26:21)

is already included in libXi 1.0.2.

Yes, this fixes the issue. :-)
