Had the same problem on a Dell PowerEdge R730 with Ubuntu 16.04LTS. Installing module mgag200 as suggested by Ivo Straka's (approach n. 1) worked for me.
But as Giorgio Signorini comment #61, after installed mgag200 module and set xorg driver to mgag200 and restart X. In /var/log/xorg.0.log, there will have somes errors like "Could not load driver maga200", and finally fall back to xserver-xorg-video-mga if installed. Actually, in xf86-video-mga 1.6.5(https://cgit.freedesktop.org/xorg/driver/xf86-video-mga/) has added support for g200e, while in ubuntu 16.04 only with 1.6.4 version(https://launchpad.net/ubuntu/+source/xserver-xorg-video-mga), and 1.6.5 only for Zesty(https://launchpad.net/ubuntu/+source/xserver- xorg-video-mga/+publishinghistory). This is because of dependency problem, or not？ Since I'm new to linux, maybe who could build xf86-video-mga 1.6.5 in ubuntu 16.04 or give some ideas about how to build? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1316035 Title: matrox g200eR2 is unclaimed in 14.04 Status in xorg-server package in Ubuntu: Confirmed Bug description: On a certified Dell PowerEdge T620 server (http://www.ubuntu.com/certification/hardware/201207-11426/) The matrox video card is not recognised: lspci | grep VGA 0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd.
