The system unexpectedly stops working and doesn't respond to keyboard input.
The system unexpectedly stops working and doesn't respond to keyboard input.
Keyboard and mouse are not functioning. The workload involves multiple browsers, a PDF viewer, and it runs on Gnome. I've installed KDE Desktop but the issue persists, though less often. It tends to occur when the system is idle while I'm elsewhere. Sometimes I can close the terminal and exit, but logging back into the GUI helps, although it doesn't always resolve the problem (particularly with KDE).
