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?
Do you have the bolt and plasma-thunderbolt packages installed? I believe I had to do that to use a thunderbolt SSD enclosure/docks with my laptop. I am not sure about DP alt mode, though.
Yes those are both installed
