this upload should fix this. Note that the patch will be removed when feisty+1 opens, so feel free to reopen this if this bug happens with feisty+1 (note that I haven't been able to reproduce this on any of my hardware combinations...)
libxcb (1.0-1.1ubuntu1) feisty; urgency=low . [ Timo Aaltonen ] * debian/patches: - 100_allow_sloppy_lock.diff from Novell, workaround to the various 'Assertion `c->xlib.lock' failed"' -bugs by setting an environment variable LIBXCB_ALLOW_SLOPPY_LOCK to any value and the check will simply be ignored. * debian/{control,rules}: - add quilt to Build-deps, and patchsys-quilt.mk to rules. - change Maintainer address. . [ Martin Pitt ] * 100_allow_sloppy_lock.diff: Reverse the patch logic for Feisty: Use sloppy locking by default for now, because we won't have time to discover and fix all broken apps. Setting LIBXCB_NO_SLOPPY_LOCK will enable the strict behaviour. This should be dropped right at the opening of Feisty+1. ** Changed in: mesa (Ubuntu) Status: Needs Info => Fix Released -- feisty: Assertion `c->xlib.lock' failed for all gl apps https://launchpad.net/bugs/88708 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
