Hello!
I'm new to Guix system, yesterday I installed it for the first time. I
installed it with i3 and Mate.
I would like to use my second monitor, but its DisplayPort connection is
not recognized by xrandr. xrandr only shows my own laptop's screen.
If I connect my second monitor through VGA, xrandr does detect that VGA
connection.
The DisplayPort connection worked fine with Trisquel, I could use my
second monitor, so I guess it's not an issue on software Freedom.
Any suggestion on how to make Guix detect my DisplayPort-connected monitor?
Thank you!

I wish I knew how to help...What's the main difference between HDMI and
display port? Does display port allow one to send video and audio down
the wire?

I don't now if DisplayPort sends audio.

I guess there must be a way if it works in Trisquel.

DiaplayPort is a (mostly) display interface standard that is unrelated to HDMI:

Amuza, does Linux register connections to your DisplayPort interface? You can check the output of dmesg.
What kind of CPU architecture are you using? Maybe some kernel config flag needs to be changed.

Thank you.
dmesg shows nothing at all when connecting to the DisplayPort port of my
docking station.
However, when connecting to the mini DisplayPort port of the laptop
itself, it shows this message repeatedly:

With Trisquel it worked good on both ports (normal DisplayPort of the
docking station and mini-DisplayPort of the laptop itself).

CPU architecture is x86_64
It is a Lenovo T430.
Please let me know if you need any other info to help me.
