Hey,
It's been a while (busy with academia) but now i have some time to try and get this working again. I'm running on a laptop with optimus, i believe that the second provider listed above is actually my nvidia card. Now i am aware that the hdmi port is connected only to the nvidia card, this would match up nicely with what i have above, i.e. i activated my nvidia card, hence activating my hdmi output, along with the outputs of the other display ports (which are connected to both cards) So it seems my problem at the moment is this: I have (what i believe to be) the latest display link drivers installed. When i plug in my usb gpu, i have a new device listed under lsusb: > Bus 002 Device 008: ID 17e9:01d7 DisplayLink And a new corresponding framebuffer device /dev/fbx appears (although interestingly it is fb1 sometimes if plugged in at boot). So my question is, why is it not appearing after calling xrandr --listproviders (which shows only my integrated and nvidia cards). Any help would be greatly appreciated. Many Thanks, Sam. _______________________________________________ xorg-devel@lists.x.org: X.Org development Archives: http://lists.x.org/archives/xorg-devel Info: http://lists.x.org/mailman/listinfo/xorg-devel
