When I press the alt key. When I press the super key. running dmesg after this unwanted logout happens I get following information: compiz[10616]: segfault at 0 ip 00007fbca309feeb sp 00007fff5f59a4d0 error 4 in i965_dri.so[7fbca2af6000+7e4000] This is caused by a mesa upgrade, which added a patch for bug #1727401. The crasher is reproduced on: - gen4 / gen5 Intel - if using modesetting X driver, like when xserver-xorg-video-intel is not installed, or the HWE stack is installed (xserver-xorg-core-hwe-16.04 defaults to modesetting) [Test case] Log in to Unity, open the dash or try to log out etc. Compiz shouldn't crash. [Regression potential] The backported patches need to be tested, here for regressions and on 1727401 that they fix the original bug (again). Best to test on a wide array of Intel HW: gen4 (965GM/GM45/G45) gen5 (Ironlake) gen6 (Sandy Bridge) gen7 (Bay Trail, Ivy Bridge, Haswell) gen8 (Braswell, Broadwell) gen9 (Apollo Lake, Skylake, Gemini Lake, Kaby Lake, Coffee Lake) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1735594/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
