Comment 3 for bug 1663922

Happens to me since about a month. IDK if xorg or some other desktop subsystem, but the screen suddenly turns unresponsive except for a very laggy mouse cursor. Most of the time it happens with firefox after seeing some video (inside firefox, like in youtube, or outside, like using videos or vlc); the video end, we go to firefox, ans out of nowhere the screen's static and the mouse looks like the machine is slow as hell.

The session's still up, as i can enter via ssh from another device. But i can't change tty with alt+ctrl+Fx, as the desktop doesn't take commands anymore.

Will try to find some log somewhere and post it here.
