Given this is failing in bo code and is a recent regression (I presume?) I wonder if this could be fallout from the 100_intel_remember_named_bo.patch patch we recently backported into libdrm.
Could you please test downgrading to the version of libdrm prior to when this patch was introduced, version 2.4.23-1ubuntu5? You can obtain i386 debs of this version from here: https://launchpad.net/ubuntu/+source/libdrm/2.4.23-1ubuntu5/+buildjob/2332340 You can go ahead and install all the debs; as a minimum you'll want libdrm-nouveau1a, libdrm2, and libkms1. You'll want to logout and log back in after installing this, for the change to take effect in your X session. Boot that and repeat the steps you take to reproduce this bug, and verify with the -1ubuntu5 version you don't see the issue. ** Changed in: mesa (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/748487 Title: compiz assert failure: compiz: nouveau_context.c:260: nouveau_update_renderbuffers: Assertion `!ret' failed. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
