From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Is there support for USB C DP alt mode via Thunderbolt? (self.linux)

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?

This is a stupid question, but you are powering the monitor externally, right?

Yes
