External monitors not recognised

Hardware Support
1

I'm looking to move to zorin as my daily driver from windows and am pretty noob to linux desktop.

Anyway, I have a problem with zorin recognising my 2 external monitors (BenQ GW2765 & ViewSonic VP2365wb) connected to my Dell XPS 15 9500 laptop via Plugable DisplayLink UD-6950H HDMI/USB3 Hub.

Graphics card is NVIDIA TU117M [GeForce GTX 1650 Ti Mobile] / Mesa Intel UHD Graphics (CML GT2)

Here's the output of dpkg -l | grep -i nvidia:

Any ideas for how I can get my monitors to be recognised?

Hello,

Have you tried newer version of Nvidia driver?

Also give us output of:

sudo apt install inxi
inxi -Ga

I've tried all of the drivers for the 535 chip as listed in Software & Updates > Additional Drivers:

Thanks for your help.

Screen-1 must be one of your of the monitor you have attached and Monitor-1 is the laptop screen? And it should see another one as well? Does this setup work in Windows or other OS'? (to rule out faulty sticks and wires)

5

Also, have you try swithcing between Xorg(X11) and Wayland to see if it makes a differences?

6

Yep, works perfectly in windows and always has done (set to dual boot).

Other devices attached to the hub work fine - keyboard, trackpad, sound etc.

I think Screen-1 and Monitor-1 are both referring to the laptop screen. Its native resolution is 1920 x 1200 and I have it set to 1680x1050.

The other 2 displays have native resolutions of 2560x1440 (BenQ) and 1920x1080 (ViewSonic).

I've not tried switching between Xorg & Wayland, tbh I only have a very vague understanding of exactly what they do. How would I go about doing that?

Log out. Click on the username and a cog should appear somewhere on the screen. Here you can choose sessions.

It was set to 'Zorin Desktop' and I switched it to 'Zorin Desktop no Wayland'.

Unfortunately this didn't make any difference.

I also tried a few different drivers on Wayland to see if that made a difference (545 driver & x.org open as well as the recommend 535).

Here's the inxi output on wayland with recommended 535 driver:

An update on this - I've got one of the monitors to work now when plugged into a different USB C dock. So it seems that it's an issue with the Plugable dock.

Maybe I need some different drivers for it?

11

I found an official driver for ubuntu, but it doesn't seem to have made any difference. Maybe needs porting?

Another update!

I've got my main monitor working when plugged into displayport instead of hdmi on the plugable, and I can plug my other monitor (which doesn't have displayport) into the other usb hub so I think I'm sorted now.

Not sure why HDMI isn't working on the displayport but at least I've got somewhere with it.

Thanks everyone for your help!
