dmesg log

On a dualhead system, the second screen (a VGA CRT with a DVI adaptor) never
shows anything, remaining in power save mode since boot until shutdown.

I disconnected the other screen, forcing this one to show the bios and boot
messages, and once while the kernel is loading, the screen goes off. The system
is reachable through ssh and seems to be working right.

When both screens are connected, xrandr shows info about both of them. I can
change resolutions on both of them, change the refresh rate on both of them,
... but no image on the screen connected to DVI.

Booting windows, dualhead works, and both screens show proper
images/resolutions/refresh.

Looking at xrandr output, it seems the connectors naming is wrong.
The screen connected to VGA is shown as connected to "DVI-I-1" and the one
connected to DVI is shown as connected to "VGA-1"
