Hi, I wonder how everyone else solves their multiple external monitors setups for the different Librem hardware - in particual Librem 5 and Librem laptops that don’t have DP Alt-mode via USB-C?
If you have Librem 13vN then you don’t have DP Alt-mode support via USB-C, and need another solution - like a DisplayLink device. This should work well on PureOS, etc. via displaylink-debian script (find it on github). Personally I run GuixSD on my Librem13 on a Sway desktop that runs Wayvnc serving a virtual output to VNC clients, and I forward a DisplayLink compatible device to an Ubuntu virtual machine running in headless mode that connects back to my GuixSD system with TurboVNC. I also have a second external monitor via the HDMI output. The turbovnc+wayvnc setup is very performant. This can be extended with more external monitors per virtual machine as Im not able to get multiple DisplayLink devices to work inside a single virtual machine.
For Librem 5 it appears that alhough it has DP Alt-mode mode via USB-C it only supports 1 external monitor - not 2. And reg. DisplayLink devices support it seems that there is support for Raspbian and Ubuntu Mate but when trying to use displaylink-debian for Librem 5 it fails (read bricks your device and you have to reflash unless you can fix it via SSH-ing to it):
Those solutions could possibly be built on to help provide support for dual monitor setups where DP Alt-mode (MST) is not available.
Anyone who has other creative work-arounds to share?
