gregrwm: 1) Regarding other reports, as mentioned multiple times previously, those are useless. Hence, if you cannot reproduce a crash, then it is most helpful if you remain focused on this report, and providing previously requested information (see below), and other information requested of you in the future. Otherwise, this will never be root caused, fixed, and backported to prior releases as applicable.
2) Regarding the question previously asked of you in https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1757299/comments/6: After reproducing the problem, if you SSH in and only kill processes that are not xorg, which processes do you have to kill until your GUI begins to be responsive again? 3) Regarding your Bug Description, at the point where you "maximize the xterm running tmux, and the GUI immediately becomes unresponsive", is there an amount of time that if you wait the GUI eventually become responsive again, and if so, how long precisely? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1757299 Title: [Dell OptiPlex 755] Intermittently GUI hangs with high xorg CPU% after launching applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1757299/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
