** Description changed: - The problem is that my GUI stops responding after launching a few - applications, and is correlated to high CPU utilization of xorg. + 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: - launched startx, - launched an xterm via twm, - launched another xterm via the first, - launched tmux, - launched firefox-esr, bluetooth-manager, and pavucontrol, - maximized the xterm running tmux + 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 - xorg stopped responding, ctl-alt-Fn don't respond either + While the above are launching, maximize the xterm running tmux, and the + GUI immediately becomes unresponsive. For example, Ctrl+Alt+Fn don't + respond. - logged in via ssh, attached to tmux, launched htop, copied htop output, - in which you can see xorg consuming lots of cpu. + After this, I logged in via ssh, attached to tmux, launched htop, copied + htop output, which shows xorg at 94.6 CPU%.
