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 Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1757299 Title: [Dell OptiPlex 755] Intermittently GUI hangs with high xorg CPU% after launching applications Status in xorg package in Ubuntu: Incomplete Bug description: The problem is that after launching a few applications, the GUI may become unresponsive, although this is not consistently reproducible. When the GUI is unresponsive, it is correlated to high CPU utilization of xorg. An example reproduction scenario is launch the following in order, and quickly: startx xterm via twm another xterm via the first xterm tmux firefox-esr bluetooth-manager pavucontrol While the above are launching, maximize the xterm running tmux, and the GUI immediately becomes unresponsive. For example, Ctrl+Alt+Fn don't respond. After this, I logged in via ssh, attached to tmux, launched htop, copied htop output, which shows xorg at 94.6 CPU%.
