Gentoo: It's not working :(
 

Hi,

just got a new display link adapter and can't get it working.

My environment is as follows:
- Gentoo Linux with vanilla kernel 4.9.2
- compiled the kernel with the UDL kernel module
- installed evdi-1.2.64-r1 and displaylink-driver-1.2.58 from the hossie-Overlay
- Desktop environment: GDM / Mate desktop

Before starting the X server I load the drivers:
# modprobe udl
# systemctl start dlm

After starting X:
$ xrandr --setprovideroutputsource 1 0

Result:
The screen appears in the screen configuration tool, but trying to set it on fails with an error notification: "The selected configuration for displays could not be applied".
It also doesn't work when I try to set a lower resolution / refresh rate.

dmesg gives me this on loading the drivers:

sometimes it finds a second device for no reason (without reconnecting the hardware; yup I set the outputsource to 2 0 then)

And this occurs in the log while trying to enable the screen:

I appreciate any help :)
Thanks!

After upgrading to the 1.2.65 drivers it does still not work, but dmesg looks a bit different now:

So it says the Painter is connected now, which is probably a good thing?

Using the screen still fails:
$ xrandr --auto
xrandr: Configure crtc 3 failed

I have the same problem
