As far as I have seen this are the logical connection going over the port.
However, I wanted to chime in for two questions I wanted to ask for some time
already:
1) i noticed the various open xorg drivers use different naming, could we unify
this in regards to dashes and counting 0 and 1 based?
E.g. DP-0 vs DP1 on intel vs. nouveau vs. modesetting vs. amdgpu, etc?
Of course not such a big deal, but it is a bit annoying to hardcode things
based on machine types and such in my display setup shell script.
2) I also have such an MST, Dell 4k display for some three years now. IIRC only
the modesetting driver does setup the two MST halfs correctly, when using the
-intel driver I have to manually xrandr --output … --left-of the two “virtual
screens” to get an output that covers the whole display.
Any thoughts on this? Any plans to generically improve this or in the intel
driver?
Greetings,
René
