Matrox graphics cards
Posted: Sun Aug 02, 2026 1:33 pm
I have bought the PCI graphics card Matrox G200 G2+/QUADP-PL/7 32MB with 4x DVI. It is an AGP card connected via PCI.
We use the new DRM driver MGAG200 since the kernel 7.2.0-rc4 and the old DRM legacy driver for Matrox g200/g400 graphics cards since the stable long-term kernel 5.10.260.
lspci -vvv
I tested it with Void PPC on my X5000/40 today. Unfortunately, the DRM driver mgag200 can't read the PCI ROM. Maybe only an x86 ROM?
dmesg | grep -i mga
xrandr detects the ports but reports that they are not connected, even though the cables are plugged in.
I also tested it with the stable long-term kernel 5.10.261 with the old legacy DRM drivers for Matrox graphics cards.
I installed the Xorg MGA server xf86-video-mga-2.0.0_3 for the old legacy DRM driver but unfortunately I get only a black screen.
