Public bug reported:
Screen freezes when I watch video in VLC media player or viewing media
on browser like Firefox. Moving mouse is of no use and Ctrl + Alt + T
short cut does not launch terminal. But I Could hear the audio even
after screen freeze.
If I press Ctrl + Alt + F1 and wait for several minutes switches to
console. I then kill the 100% cpu process (like VLC or Firefox) then
switching to GUI (CTRL-ALT-F7) brings back the screen and I am able to
work as usual or sometimes returns to login screen.
