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
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
Steps to Reproduce:
1.Setup XF86Config for xinerama and 4 heads
Expected Results: Should have all heads appear as single graphics logical
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"
