I try and take good notes setting things up, but all I have is "doesn't work on secondary head". My memory is that I saw a reason why it doesn't work on the secondary head but my Googling isn't finding that right now. Oh, maybe it's because I'm using Xinerama. ftp://ftp.matrox.com/pub/mga/archive/linux/2002/lnx200notes.txt After starting X, there should be a "direct rendering enabled" message in the X server startup log. Please note that DRI isn't enabled if you're using the Xinerama extension. You may want to keep two "XF86Config" files on hand -- one for DRI and the other for DualHead. Hum, that just talks about DRI, not OpenGL. On my main head I get about 200fps with glxgears. On the second head the window goes black and my machine gets very slow. BTW -- I also get: (EE) MGA: Failed to load module "mga_hal" (module does not exist, 0) My guess is I upgraded my kernel at one point and didn't move over that module. I thought that was for Matrox's PowerDesk, which I don't have installed. The HAL library is not required for basic DualHead support (without a DVI monitor)" Which is my case. -- Bill Moseley [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
