(I guess if it shows up in xrandr, that's a pretty good sign.) As far as I can tell, the provider stuff is set up correctly as per the link (I'm not sure as to what specifically you would like me to confirm, could you please elaborate?). On closer inspection, I think the VBIOS issue is related, *but not limited* to my DP problems; I can't seem to access the GPU with other methods, i.e using the method described in the above link or via bumblebee for example. > Lastly, the reason for the VBIOS errors is that we hit unexpected opcodes in > some scripts.
