Bug Description
[Problem] USB external disk read/writes which the systems reports by turning the monitor to text only, but X continues to work. The main laptop screen will suddenly switch to "black screen with text (the error message), a blinking cursor and a working mouse pointer", while the external monitor continues to work ok. Please also refer to video, as it is slightly difficult to explain in writing only: http://
The X.org log gets flooded with the below when it occurs:
(WW) intel(0): first get vblank counter failed: Invalid argument
WORKAROUND: Disconnect the external monitor.
