terminal output
SUMMARY Clicking on the volume/audio icon in the system tray causes a black
screen. The mouse cursor remains visible and movable, but the entire desktop
shell (plasmashell) becomes unresponsive. The issue is intermittent and
typically occurs after several interactions (e.g., on the 10th click). I have
to manually run killall -9 plasmashell from a terminal to recover.
STEPS TO REPRODUCE
Log into a Plasma (Wayland) session.
Use NVIDIA Driver 580.95.05.
Click on the Audio volume icon in the system tray multiple times.
OBSERVED RESULT The screen turns black, and the Plasma shell freezes. Only the
cursor is visible.
EXPECTED RESULT The audio volume applet should open normally every time without
freezing the desktop.
