Comment 10 for bug 126931

Well what do you want me to backtrace exactly ?
X is not crashed or freezed. It is only the display that is not showing anything.
Reproducing it several times I have this morning for example a completly red screen.

If I switch to console mode then to X, KDM will be displayed correctly.
It seems to be a problem when switching from bootsplash to X. And it seems random so maybe time dependent.

The bt when X is in this state is the following :
