[p]Interface is USB 2.0. Tested with PureOS Byzantium KDE amd64 ISO from 2022-02-22.[/p]

[p]idProduct field in lsusb is the empty string; this h-node entry uses the iProduct field as a substitute pending a resolution to [a]https://h-node.org/issues/view/en/406/1/token|h-node Issue 406[/a].[/p]

[p]Requires manual configuration:[/p]

[enum]
[*] Blacklist udlfb driver to work around [a]https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1011986|Debian Bug 1011986[/a]: echo "blacklist udlfb" | sudo tee /etc/modprobe.d/displaylink.conf[/*]
[*] sudo apt install arandr[/*]
[*] Reboot the PC.[/*]
[*] Connect display to USB device.[/*]
[*] Connect USB device to PC.[/*]
[*] xrandr --setprovideroutputsource 1 0[/*]
[*] ARandR will now show a new DVI-I-1-1 output.[/*]
[*] Activate that new output in ARandR.[/*]
[/enum]

[p]Some hardware functionality, e.g. 24-bit color depth and Huffman compression, is not supported with free drivers (but works fine with non-free drivers). I didn't test full Full 1920x1080 resolution; my test display only supports up to 1280x1024 (which resolution works fine). fine. Sometimes, hotplugging will crash X11. I only had success with X11; Wayland only gave me a black screen on the DisplayLink output (maybe there's a Wayland incantation I don't know about).[/p]

[p]This device contains non-free firmware running on an 8051/MCS-51 core. This firmware is not loaded by the host, so it doesn't violate GNU FSDG, but it may be objectionable to users who are stricter on firmware freedom than FSF is.[/p]
