I do have a server with Matrox G200eW3 (on-board) on Debian Bookworm, but graphic display fails. There is a small _ in the top left corner, but that's all. Still the terminals (ctrl-alt 2/3/4/5) are working. When I put in Nvidea PCI Graphic all is fine.

On another server with same Matrox GPU the lsmod
for mgag200
shows used 1 and I have a graphic desktop display.
Removing the mgag200
with rmmod
also the terminals are gone, still I can connect with ssh.
modprobe mgag200
does not report any error, still the used count of lsmod
stays zero and there is no graphic desktop.
Don't know what's failing me ...
thx for any hints!
