[/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 1920x1200 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]
