Debian 10 + USB-C display

Postby jp.19810522 » 2019-07-15 08:51

I am trying to make it work an display connected through a docking hub https://www.visiontek.com/dual-4k-usb-dock.html (usb-c).

I installed evdi
Code: Select all
root@debian:~# apt search evdi
Sorting... Done
Full Text Search... Done
evdi-dkms/stable,now 1.6.0+dfsg-1 all [installed]
  Extensible Virtual Display Interface driver kernel module

libevdi0/stable,now 1.6.0+dfsg-1 amd64 [installed]
  Extensible Virtual Display Interface driver client library


Module is loading
Code: Select all
root@debian:~# lsmod | grep evdi
evdi                   65536  0
drm_kms_helper        200704  3 evdi,nvidia_drm,i915
drm                   483328  16 drm_kms_helper,evdi,nvidia_drm,i915


I am using X11
Code: Select all
jp@debian:~$ echo $XDG_SESSION_TYPE
x11


but I got only one provider
Code: Select all
jp@debian:~$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x47 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 3 outputs: 5 associated providers: 0 name:modesetting


and not monitor plugged in
Code: Select all
jp@debian:~ xrandr
eDP-1 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 346mm x 194mm
...
DP-1 disconnected (normal left inverted right x axis y axis)
DP-2 disconnected (normal left inverted right x axis y axis)
HDMI-1 disconnected (normal left inverted right x axis y axis)
HDMI-2 disconnected (normal left inverted right x axis y axis)


Any tip for making this work ?

Do you have DisplayLink driver?
On page, which you have linked, there is written:
VisionTek: VT4000 Universal Dual 4K USB Dock wrote:DisplayLink Drivers required for proper functionality: DisplayLink.com

thank you for response. I tried https://github.com/AdnanHodzic/displaylink-debian but ... GUI didn't start after the installation. Any experience on this ?
