=> and 2 screen : one is the computer, the other my TV witch doesn't have the
same resolution (less).
-- Information about the crash:
I was plugin the HDMI cable to have my desktop on my TV.
Turn off, turn on, turn off turn on my tv and it crach.
More generaly, I notice that the only way to have a desktop working on tv is to
do this in the order :
1) let linux turn on
2) if I plug an HDMI cable the TV must be Off
3) when I am completly log in my computer, now put on the TV
If you don't do that the desktop is in mess ot it crash (but less those 2 last
month : a correction?)
The crash can be reproduced every time.
