Matrox chips only have one overlay and it is limited to the first head as I recall. This is a hardware limitation. You might be able to get it working with two matrox cards since each one would have an overlay to work with, but I've never tried it. Alex ---------------------- Hi, all. When I try to fire up both Xinerama and Overlay on my G450 32 MB, it dies with "Incompatible screens. Root window depths differ" [I'll post the whole log below.] I can get either Xinerama -or- Overlay to work just fine. Lastly, according to this link: http://calmarc3.cchem.berkeley.edu/archives/bum/02/archive/0058.html they do appear to be mutually exclusive. Is this true? Might it be fixed in 4.3? Would it work if I used two different G400's, instead of just one G450? Thanks, Ken D'Ambrosio Sr. SysAdmin Xanoptix, Inc. __________________________________ Do you Yahoo!?
