Thanks. It sounds like your gnome-shell process has crashed or frozen. When that happens you might be able to interact with apps still as those run through Xorg which has probably not crashed... Next time it happens, please:
1. Wait 10 seconds. 2. Reboot. 3. Run: journalctl -b-1 > prevboot.txt 4. Attach the resulting text file here. 5. Also check for any crashes using these steps: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1946258 Title: Panels unclickable after screen area capture Status in gnome-shell package in Ubuntu: Incomplete Bug description: When I try to capture screen area using gnome tool, mouse pointer changes to a cross and it is impossible to click on left or top panels. Closing gnome screen capture toll does not help. I am only able to do Alt-Tab, Ctrl+Alt+T and Ctrl+Alt+Del. Logoff and Logon help to fix the problem. It appears more often when Remmina is active.
