Does Linux support this? I am trying to connect my laptop to a monitor via USB C. The laptop has two Thunderbolt ports and the monitor has support for USB C DP alt mode. I have tested the same setup on my work laptop (windows 11) and it works fine but my laptop running arch does not work. My laptop detects the monitor correctly so it shows up in the KDE plasma display configuration but the monitor is not getting any input. As far as I could tell this is supported in the kernel. Am I wrong? Am I missing some important package?
yeah displaylink is sort of a streaming feature, but evdi is a kernel module that makes the kernel aware of multiple monitors over usb (among other things), it’s required for display plug-n-play over usb in my experience.
It is not required for the displayport alternate mode of usb-c.
It is an alternative with limited performance that is built on top of usb and does not require hardware support on the PC side.
