I just upgraded my X server at work. Oh my god. I had a working configuration with multi-head (without Xinerama).
I was happy. Oh yes I remember yesterday everything was so fine. And now it screwed everything up.
I've got 3 LCD screens and 2 Matrox G450 PCI cards. After restarting X.Org 7.3, all I've got was two screens (connected on the first card) in clone mode. Very useful.... After 1 hour of googling I managed to use xrandr to setup a Xinerama display on this 2 screens....
I don't want Xinerama and I want my other Matrox card back. I don't know why but reading Brice Goglin post around, I understand that the old behaviour is no more available. GREAT, now I'm stuck with Xinerama that a lot of window managers don't handle correctly and I still don't know why my other Matrox card doesn't work.
Is X.Org 7.3 a piece of shit or what?
