Arch, Matrox and mga.

Dearest Arch forum,

I'm admitting defeat as I'm writing this post.

I've been trying for hours to have Arch work on a Dell PowerEdge T310, with only a little component refusing to work: its video card, a Matrox G200eW (WDDM 1.2).
The "mga-dri" package (as well as Xorg, lightdm and lightdm-gtk-greeter) have been installed, but somehow the "mga" module is not loaded (as in, Xorg fails to find such file).
Starting the computer using a Debian Sid installation on a usb device, everything seemd to work. I proceeded to generate a working xorg.conf file via "Xorg :0 -configure" to try out on Arch, but to no avail.

The X server is not started, still complaining it could not load the "mga" module. I've also read on the wiki about adding OldDmaInit (which is commented in the above file), but nothing at all changed. I admit I've rarely had such issues with Xorg (well, after Bumblebee at least), although it's the first time I ever have to work with a Matrox card.

xorg.conf:

The fun part is that starting tomorrow I'll be on vacation until Genuary 8th, and this is going to haunt my nights! XD
Any kind of help to solve this matter is kindly appreciated, as I really have no idea on what to do

Lone_Wolf · 2016-12-28 16:37:29

You need xf86-video-mga, but that was removed from repos, https://www.archlinux.org/news/xorg-ser … available/ .

It looks like that package was never migrated to AUR 4, but you can find the most recent version here : https://github.com/aur-archive/xf86-video-mga .

Gusar · 2016-12-28 16:39:44

The mga module mentioned in those logs is provided by the xf86-video-mga package. The problem is, Arch doesn't have this package anymore. It's not even in AUR. So you'll need to write a PKGBUILD yourself or compile the driver manually.

Edit: Lone_Wolf was faster . He even found a PKGBUILD, nice! However, the version compiled by that PKGBUILD may not work with modern versions of xorg-server anymore. It will definitely not work with xorg-server-1.19, you'll need the git version of xf86-video-mga for that.

...That explains a lot! Many, many thanks!
Now Xorg starts correctly, and it's way more responsive! I can't believe I've missed something like that, i feel so silly!
