Triple monitor setup in linux
- by Brendan Abel
I'm hoping there are some xorg gurus out there.
I'm trying to get a three monitor setup working in linux. I have 2 lcd monitors and a tv, all different resolutions. I'm using 2 video cards; a 9800 GTX and 7900Gt.
I've seen a lot of different posts about people trying to make this work, and in every case, they either gave up, or Xinerama magically solved all their problems.
Basically, my main problem is that I cannot get Xinerama to work. Every time I turn it on in the options, my machine gets stuck in a neverending boot cycle. If I disable Xinerama, I just have three Xorg screens, but I can't drag windows from one to the other.
I can get the 2 lcds on Twinview, and the tv on a separate Xorg screen no problem. But I don't really like this solution. I'd rather have them all on separate screens and stitch them together with Xinerama.
Has anyone done this?
Here's my xorg.conf for reference.
p.s. This took me all of 30 seconds to set up in Windows XP!
p.s.s. I've seen somewhere that maybe randr can solve my problems? But I'm not quite sure how?
