I have had a hard time getting acceleration and direct rendering working on Matrox G550 on current software. This old hardware seems to be very poorly supported any more. The source for my information is https://bbs.archlinux.org/viewtopic.php?id=137666. I started a new topic for Matrox G550 and possibly other Matrox cards that have the same issues.
I will first list what I have observed and learned.
xorg-server 1.13 does not support XAA acceleration. EXA acceleration support is very faulty. Almost all acceleration options have to be turned off for EXA. Otherwise the server crashes on startup.
Option "AccelMethod" "EXA"
Option "EXANoComposite" "True"
# Option "EXANoUploadToScreen" "True"
Option "EXANoDownloadFromScreen" "True"You do not get DRI with this setup -> Video output is horribly jerky.
GLX worked before my last system update. Now glxgears is also not hardware accelerated. I did not try to find out what broke it this time because the direct rendering issue is still a bigger problem.
My guess is that XAA support is not going to return to xorg-server. I also guess that nobody is going to fix the problems with EXA for such old hardware. My solution for now and possibly for ever is to freeze xorg-server 1.12 and some other packages needed for DRI and acceleration. I would not mind being proven wrong in my presumptions. Frozen packages tend to become a problem sooner or later.
I have installed:
xorg-server-1.12.4-1
from /var/cache/pacman/pkg
xf86-video-mga-1.5.0-1
This is from abs. I compiled it with modified PKGBUILD:
./configure --prefix=/usr --enable-drimga-dri-7.11.2-3
This is from current repo. Not frozen for now.
xf86-video-vesa-2.3.2-1
from /var/cache/pacman/pkg
xf86-input-evdev-2.7.3-1
from /var/cache/pacman/pkg
/etc/pacman.conf contains:
IgnorePkg = xf86-input-evdev xf86-video-mga xf86-video-vesa xorg-serverThis is also the relevant part of my /var/log/pacman.log. I had to clean it up quite a lot because I made several attempts with different package versions before I realised that I had not yet reinstalled lxdm which had some ill effect on starting the graphical environment.
