Right now it looks like LightningCrash is right. The log file contains an error saying that I need mga_hal for multihead, available from www.matrox.com
. I've now tried installing their driver, but it complains about my version of xorg. It seems they do not support xorg beyond version 7.0 . I am currently working with a fresh install of debian lenny running xorg version 7.2 . (I added the etch repository, and found that it contains 7.1) Their installer refuses to install, and their source (designed for 7.0) is giving me dependancy issues.
I think I may have to shelve this card until matrox updates their driver. I may have other cards available to me later today. I will probably need to do multi head through using multiple cards.
Thanks for the help, both of you.
If I don't post in this thread again, then I'll see you around on the forum!
