When using displaylink-debian inside a VirtualBox VM the display wont work.
Information about the display:
Used Chip is a Displaylink DL-165 with a USB 2.0 connection.
There are two dispays over a single USB cable connected. Furthermore both displays support touch, but this works independently from the displays.

System is a Kubuntu 23.04 VM running on a Windows 10 system. EFI and secure boot are disabled for the VM. TPM is also disabled. All USB-Devices are properly passed to the VM.

Observing and testing some things resulted in the following observations:

  1. After installing drivers via displaylink-debian xrandr --listproviders retuns two more providers as expected for a dual display device
vincent@VM-Kubuntu-23:~/Downloads/displaylink-debian$ xrandr --listproviders 
Providers: number : 6
Provider 0: id: 0x648 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting
Provider 1: id: 0x626 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting

Provider 5: id: 0x87 cap: 0x2, Sink Output crtcs: 1 outputs: 1 associated providers: 0 name:modesetting
  1. Running xrandr --setprovideroutputsource 1 0 results in the following errors (for all combinations of providers):
vincent@VM-Kubuntu-23:~/Downloads/displaylink-debian$ xrandr --setprovideroutputsource 1 0
X Error of failed request:  BadValue (integer parameter out of range for operation)

  1. Observing syslog when connecting the display or restarting the system results in the following output:

Especially the lines with the following error seem to be connected to the issue:

kernel: [ 1591.513859] udl 2-2:1.0: [drm] *ERROR* fbdev: Failed to setup generic emulation (ret=-22)

These lines are also displayed initially during boot.

  1. I observed that both displays worked for a very short moment, after initially installing displaylink-debian.
    When the installation finished I confirmed the reboot via the request in the script. After the system shutdown the Kubuntu logo was shortly shown during the startup process on both displays until the error mentioned in 3. was shown on the main display.

  2. When looking at the common issues / post install guide I wonder why I have four providers listed with xrandr --listproviders but no one can be easily identified as main provider.

  3. Disconnecting the display, unloading the udl kernel module with rmmod udl, loading udlfb via modprobe udlfb and reconnecting the displays results in both screens turning green, signalizing that from hardware and framebuffer side everything is working fine.
