Status in “xorg-server” package in Ubuntu:
New
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. G200eR2
lshw -C display
*-display UNCLAIMED
description: VGA compatible controller
product: G200eR2
vendor: Matrox Electronics Systems Ltd.
physical id: 0
bus info: pci@0000:0a:00.0
version: 00
width: 32 bits
clock: 33MHz
capabilities: pm vga_controller bus_master cap_list
configuration: latency=64 maxlatency=32 mingnt=16
resources: memory:d8000000-d8ffffff memory:deffc000-deffffff
memory:de000000-de7fffff
Thus xserver is not hardver accelerated.
Also /dev/dri and /dev/dri/card0 is missing.
kernel module mga is not loaded, although if i manually load by modprobe it
works fine
modprobe mga
lsmod | grep mga
mga 40811 0
drm 302817 1 mga
