Linux 3.2: After resume screen only turned on after switching terminals

Dear Linux folks,

resuming from suspend to RAM the monitor was indicating by a blinking LED that it did not receive any signal. This is the first time this happened. Resuming from suspend to RAM had worked without problems before (and probably will work again the next tries).

Logging in from SSH worked fine though. Switching terminal to tty1 nothing changed but going back to tty7, where X was supposed to run), and the monitor detected a signal and showed the screensaver.

Switching to tty1 still does not work though, that means the monitor indicates that it gets no signal.

The motherboard is an ASRock A780FullHD [1] and the OS is Debian Sid/unstable.

I attach the output of `dmesg` and `/var/log/Xorg.0.log`.

Thanks,

Paul
