From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows 98; Win 9x 4.90) Description of problem: I am running redhat 8.0. I have a G450 quad head card. With Xfree86 and xinerama option I can only get the first head output to work correctly. The other heads display a corrupted image. An xterm can be dragged from first display across to a second but the resulting image is corrupted on 2nd screen. I can only get the 2nd, etc to display anything if I explictly set the VideoRam option of the Device section. Are there any special options I should set. It looks as though its almost working but for some magic option I'm missing. I seem to have all the usual settings in XF86Config that appear on various web pages for xinerama. Is it important that I set option MGASDRAM instead of VideoRam? Is their a magic Xaa option? I have obtained latest mga_drv.o from matrox. Version-Release number of selected component (if applicable): standard version that came with personal redhat CD How reproducible: Always Steps to Reproduce: 1.Setup XF86Config for xinerama and 4 heads Expected Results: Should have all heads appear as single graphics logical screen Additional info:
G450 quad-head isn't supported by the mga driver from what I can see in the sources. You'll probably have to use the proprietary unsupported Matrox driver. Setting status to "NOTABUG"
