Bug#442907: xserver-xorg-video-mga: Multihead doesn't work on G450
I noticed the same problem with Matrox G550 and driver
xserver-xorg-video-mga 1:1.4.7.dfsg.1-3, only the first monitor works
while Xorg.0.log does not report any problems about the second.
Trying with the driver version from the experimental
(1:1.9.99.dfsg.1-1) with the same config gives some kind of clone mode
with weird resolutions for two monitors with several graphical
glitches. I tried to change the config with grandr but it did not
give any other choice than the clone mode, but this might be fault of
grandr and not the driver. The man-page of xrandr does not look very
inviting so I did not yet try changing the settings with it, and
instead downgraded the driver and some other xorg packages to the
versions in testing to get a working set up.
Are these newer drivers likely to get fixed anytime soon or is the
"medium term" solution to stay with 1.4.6 driver? I am personally not
very motivated to try to fix or hunt for bugs in the experimental mga
driver (good reason to get rid of the POS matrox if anything), and
maybe nobody else is either for such old cards...
