We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu since that time.
Ubuntu 14.04 (trusty) reached end-of-standard-support on April 25, 2019. Do you still see a problem related to the one that you reported when using a currently supported version of Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time. Thank you for helping make Ubuntu better. ** Changed in: xorg (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1498058 Title: Display freezes Status in xorg package in Ubuntu: Incomplete Bug description: Display freezes with the following repeating: Sep 21 18:06:40 ervin-Lenovo-G550 kernel: [ 2589.417953] nouveau E[ PGRAPH][0000:01:00.0] TRAP_MP_EXEC - TP 0 MP 0: INVALID_OPCODE at 07e6c0 warp 29, opcode ffe7f2f6 ffe7f2f6 Sep 21 18:06:40 ervin-Lenovo-G550 kernel: [ 2589.417975] nouveau E[ PGRAPH][0000:01:00.0] TRAP_MP_EXEC - TP 0 MP 1: INVALID_OPCODE at 07e6c0 warp 28, opcode ffe7f2f6 ffe7f2f6 Sep 21 18:06:40 ervin-Lenovo-G550 kernel: [ 2589.417981] nouveau E[ PGRAPH][0000:01:00.0] ch 7 [0x001f7e0000 chrome[2686]] subc 3 class 0x8597 mthd 0x1b0c data 0x1000f010 WORKAROUND: Use proprietary nvidia drivers.
