Hi,
Thanks for answering. I am still new to virtualGl, so i don't have it
working quite yet. I edited my xorg.conf file to look light:
Section "Device"
Identifier "Device0"
Driver "matrox"
VendorName "Matrox Electronics Systems Ltd. "
BusID "PCI:10:0:0"
EndSection
and i restart lightdm, and then i try and run vglrun <program> but i get:
[VGL] ERROR: Could not open display :0.
I also have tried BusID "VGA:10:0:0"
and here is my bus info:
0a:00.0 VGA compatible controller: Matrox Electronics Systems Ltd. G200eR2
(rev 01)
Do you know what i'm doing wrong? Thanks!
Thomas
