Public bug reported:
Xorg suddenly stops updating the display and CTRL+ALT+F1 does not work.
The issue happens randomly and does not seem to be related to content
being rendered. This time the display hang occurred while I was typing
in gnome-terminal.
I can successfully ssh into the system from another computer and run
ubuntu-bug xorg while the display is frozen.
Disconnecting the display port cable and reconnecting does not
successfully restore the image. However, after disconnecting the cable
and reconnecting, the monitor never resumed from DPMS suspend so the
signal emitted did in fact change when I disconnected the cable.
The problem occurs both with official lowlatency Ubuntu kernel and
custom kernel built from vanilla kernel sources. I haven't found a way
to deduce if this is in reality caused by kernel, xorg or the hardware.
However, considering that this happens with many different kernel
versions, I'd assume this is caused by xorg, instead.
