Public bug reported:
Hello,
I can boot with a dual screen : one on the DVI port and the second on
the HDMI port.
Then, if I unplug the HDMI screen, everything goes normal : the last
screen is the unique screen and the display act as expected.
But, if I try to plug again the HDMI screen, the display become black
and I can't do anything. I have to switch off the electricity to the
computer (unpluging the HDMI screen does not work).
Here last syslog lines :
