NVIDIA Proprietary Driver supports KMS now - can the DisplayLink driver support it?

What's the output of

xrandr --listproviders

What happens if you use

xrandr --setprovideroutputsource 1 0

?

Cheers,
Michal

peter@computer:~$ xrandr --listproviders
Providers: number : 3
Provider 0: id: 0x206 cap: 0x1, Source Output crtcs: 4 outputs: 2 associated providers: 1 name:NVIDIA-0
Provider 1: id: 0x46 cap: 0x2, Sink Output crtcs: 3 outputs: 4 associated providers: 1 name:modesetting
Provider 2: id: 0x46 cap: 0x2, Sink Output crtcs: 3 outputs: 4 associated providers: 1 name:modesetting

peter@computer:~$ xrandr --setprovideroutputsource 1 0
peter@computer:~$

After I insert this command, there is no signal sent to the 2 screens. There is only the laptop screen recognized in the display settings.

Looks like there's yet another provider number 2. I guess 0 and 1 are for NVIDIA optimus setup, probably 2 will be evdi. So, try with 2 and 0.

I have tried

xrandr --setprovideroutputsource 2 0

There is still none of the displays recognized.

What's the output of `xrandr` after doing the above? Do you see a DVI-*-* connector, if yes, does it look connected or not? Does `xrandr --auto` trigger any change?

Do you see a DVI-*-* connector, if yes, does it look connected or not?

"xrandr" does not report any "DVI-" text.

Does `xrandr --auto` trigger any change?

Unfortunately not.

Any further ideas? It would be a real improvement, if the "official" driver from Nvidia would be supported.

[mlukaszek]

I don't see any connector that would be related to evdi; so I'm curious what would it log from the machine boot, with verbose logging on. (try passing "initial_loglevel=6" via /etc/modprobe.d/evdi.conf)
