Bug Description
While typing, the Dash Home appeared. Hitting Esc in an attempt to dismiss the Dash Home caused the screen to go black and the mouse cursor to only move on the screen every few seconds. After hitting Ctrl+Alt+F1 to try to gain access to the console, these messages were observed and looping every five or so seconds, followed by a flash of random colours:
[drm] nouveau 0000:01:00.0: GPU lockup - switching to software fbcon
[drm] nouveau 0000:01:00.0: Failed to idle channel 1.
[drm] nouveau 0000:01:00.0: Failed to idle channel 2.
