Monitor on Displayport

superpunk

Hi dear community!
I have a Tuxedo Aurora 15 Notebook and want to use it with a second Monitor connected on a docking station (Displayport, USB-C). Mouse and keyboard are working fine via the docking station, but I don't get the monitor running at all. I searched the discussions but found nothing of great help unfortunately. Maybe somebody can give me some instruction what I can try, sorry I've got pretty small knowledge on Solus but I love it and want to stay.
I ran inxi -G which gave me this:


  Device-1: AMD Renoir driver: amdgpu v: kernel
  Device-2: Acer BisonCam NB Pro type: USB driver: uvcvideo
  Display: x11 server: X.Org 1.20.14 driver: loaded: amdgpu,ati
    unloaded: fbdev,modesetting,vesa resolution: 1920x1080~60Hz
  OpenGL: renderer: AMD RENOIR (DRM 3.42.0 5.15.30-212.current LLVM 13.0.0)
    v: 4.6 Mesa 21.3.7

Also I ran xandr -Q:

eDP connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   1920x1080     60.01*+  40.00  
   1680x1050     60.01  
   1280x1024     60.01  
   1440x900      60.01  
   1280x800      60.01  
   1280x720      60.01  
   1024x768      60.01  
   800x600       60.01  
   640x480       60.01  
DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)

Thank you for any help!
Cheers!

superpunk Hello you need to set it up in - Settings > Displays

riffer

I see the computer has "1 x USB 3.2 Gen2 Typ C Full-Featured (Displayport 1.4 (max. 7680 × 4320@60Hz), Power Delivery DC in Charging-Function*)". Does the dock have a similar port? Does your monitor have a similar USB-C port that you can connect up directly?

superpunk

riffer Thanks for your answer. The Docking is this one: https://i-tec.pro/en/produkt/cadual4kdockpd-2/
The monitor is connected via Displayport or Hdmi, right now via Displayport but it didn't work with HDMI as well.

My monitor doesn't have a USB-C port.

craigtoyoracer I tried this as well, but it doesn't appear in the settings at all.

Isn't there anybody else who has problems with getting a display up and running via Display Link?

Bhibb

superpunk So I do have intermittent issues with my Display Link connected monitor, but it's on a desktop running through the GPU. I'm running Solus on Budgie.

Every once in a while the display will just fail until I pull out the cable and plug it back in. I would say this is the cable, but I've replaced the cable. I moved on to just accepting that maybe my power supply has hiccups and kills the connection every once in a while (talking maybe a few times a month).

But as far as your issue of not even getting it up and running, unfortunately I can't say I'm having that difficulty. Sorry! (This probably wasn't helpful, but I am having problems with my DP, so I thought I'd offer my two cents)

pomon

What resolution and frequency does your monitor have? You will probably need to add new modeline.

Bhibb

pomon My monitor is a 3440 x 1440 (21:9) at 99.98 Hz. Not sure what a new modeline is, but I'll look it up!

try:

xrandr  --addmode DisplayPort-0 3440x1440_99.00
xrandr --output DisplayPort-0 --mode  3440x1440_99.00 # or do not perform this command, just go to the monitor settings and see if the monitor is visible

The monitor should be connected to DisplayPort 0

Bhibb

pomon When I try this, xrandr doesn't recognize -hsync. I checked the --help and saw that there are valid flags that look like this, but they're not in the right place, probably.

xrandr: unrecognized option '-hsync'
Try 'xrandr --help' for more information.

Bhibb Remove from the first entry Modeline/
xrandr --newmode "3440x1440_99.00" 720.25 3440 3728 4104 4768 1440 1443 1453 1527 -hsync +vsyn

Bhibb

pomon Perfect, that made the first command work. Your second for adding couldn't find DisplayPort-0

xrandr: cannot find output "DisplayPort-0"

pomon

You've sure you connected the monitor to DisplayPort-0? Xrandr you have:

DisplayPort-0 disconnected (normal left inverted right x axis y axis)
DisplayPort-1 disconnected (normal left inverted right x axis y axis)

Check the port DisplayPort-1

Bhibb Well, which output is the monitor?

Bhibb

pomon The monitor looks to be DP-4, currently.
