Matrox G400 and RH9
Jim Wiggs
I recently had to do a full reinstall on a dual PII box, and
decided to install RH9. The box has a G400 w/16 MB RAM on it,
and dual monitors which were previously working fine under RH 7.3
using the drivers from Matrox. We installed the latest Matrox
drivers after putting RH9 on the box, and encountered lots of
problems. GL-based screensavers would kill X; Mozilla 1.2.1,
1.3, 1.4, and Firebird 0.6.1 all froze within a few minutes of
starting. Eventually, we could not start them at all. We pulled
the Matrox drivers off and went back to single-monitor mode, and
the problems went away. However, I refuse to go without the
second monitor on the box.
Extensive searches of Google and Google Groups turned up
information that you could run XFree86 4.X with dual heads on a
Matrox card without using the Matrox drivers, but I have not been
able to get it to work. The best I've managed is to get X to
start one head with what should be a dual-monitor XF86Config file,
but without crashing the box. The Xinerama "On" setting in the
ServerFlags section does not seem to be turning xinerama on, and
the output in /var/log/XFree86.0.log complains that we need
mga_hal.o from Matrox to do dual-head. Can anyone help out here?
I'm looking for a step-by-step if it's available, but if not, any
clues would be appreciated. Current XF86Config file is appended
below.
thanks,
Jim Wiggs
