Public bug reported:
The HDMI output to an external screen or projector
is corrupted, the GUI is not responsive and no further configuration can be
done.
By corrupted I mean that:
* the screen is blinking from black to some colors and back
* the screen is formed of stripes that, somehow, resemble the desktop, but are
misaligned and screwed up.
The system/screen status cannot be restored by disconnecting the HDMI cable,
but it seems to be not a kernel problem as I can easily restart lightdm
from a terminal (ctrl+alt+f1) to login again.
I tried with and w/o the intel drivers for both the standard kernel and the
4.0.2.
Nothing changes, the problem persists.
HDMI output works perfectly with Gnome Shell, hence I think that this is
a unity/compiz bug.
The problem was not present in July.
