Public bug reported:
Box is connected to new LG LED TV over HDMI. After resuming from
standby, the screen is completely scrambled. Like it is broken in
diagonal lines.
If the color on the screen are changed, it is visible on the screen, but
not the shapes. Like bad sync.
Switching between HDMI ports is very fast on this TV, so maybe there is some
caching envolved.
It happens only if the TV was turned off (put on standby) during time Ubuntu
was on suspend!
The proprietary driver doesn't have this problem (has another one, so
can't use it).
I have found a quick workaround for this problem by switching screens
(Ctrl+Alt+F1 -> Ctrl+Alt+F7). This corrects the display.
