Debian 11 Bullseye Wavlink WL-UG35001H

[imerelli247]

I have Debian 11, Kernel 5.10 on HP-17 laptop and USB-to-HDMI card WL-UG35001H. None of the Ubuntu drivers worked (any version). Finally, this displaylink-debian 6.01 driver installed, with some adjustment during installation. Here how it worked for me:

1. Install evdi-dkms from Debian repository;

2. Reboot;

3. Run "sudo displaylink-debian.sh", no error should be reported. If any package is missing, install it and run it again. I ran Uninstall option after each unsuccessful installation. linux-headers-amd64 was installed before;

4. Reboot;

5. In /etc/X11/xorg.conf.d/20-displaylink.conf replace existing text with:
   Section "Device"
   Identifier "DisplayLink"
   Driver "modesetting"
   Option "PageFlip" "false"
   EndSection

6. Reboot or run "systemctl restart displaylink-driver.service";

7. Run "xrandr --setprovideroffloadsink 4 0" . The options 1 0, 2 0, 3 0 did not connect;

if display did not come up, run "systemctl restart displaylink-driver.service" again. Use commands in Post Installation Guide to verify installation and set monitor after step 4.
