** Description changed: [Impact] Crashes the X.org server for some people several times a day. [Test Case] 1. Start Xephyr 2. killall Xephyr Broken Behavior: Aborts with SIGSEGV and a backtrace Fixed Behavior: Exits cleanly [Regression Potential] - Will regress LP #968845 so more work needs to be done on that. - Since this is effectively a rollback to 2:1.11.4-0ubuntu10.1 - I expect no further side effects. + Reverting the patch from 10.2 will regress LP #968845, + but adding patches from the X-server git tree seems to + fix the issue. Any xserver bug reports will have to be + watched closely, especially if they mention suspend/resume. + The x server git tree will have to be watched as well, + in case any fixes/crashes related to the code are fixed there.
