2º display detected but not working

Hello, I recently migrated from windows and started using Linux/Ubuntu.

Everything was going fine until I connected my notebook to a monitor/display.

Here is the config I am running:

Hardware model: SAMSUNG ELECTRONICS CO., LTD. 550XDA
Memory: 8 GB
Processor: 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz × 8
Graphics: Mesa Intel® Xe Graphics (TGL GT2)
OS: Ubuntu 22.04.1 LTS
OS Type: 64-bit
GNOME Version: 42.4
Windowing System: Wayland

As you can see the display was detected by the system:

Despite this my second screen is all black. I already tried it on another computer and it works just fine. The problem is something with this config. Maybe the graphics card? Mesa Intel® Xe Graphics (TGL GT2).

Can someone please help? I really need this setup working for my studies.

Thank you very much.

Welcome @Octavio_Garcia ,
Have you tried going back to X11?
Is Ubuntu fully updated?
You may get better drivers for the video card if you enable non-free software repository
Check your cables

Other than that, I do not know. I am not a video expert.

Neville

Sorry but what do you mean by x11?

Hi Octávio :wave:

The X Server is the user-side part of the X Window System. The X Window System (also: just “X” or “X11” or “X Version 11” - but not: X-Windows) is a collection of protocol standards and computer programs for creating a graphical user interface

(from XServer › Wiki › ubuntuusers.de ; translated from German)

Hope it helps.

Many greetings
Rosika :slightly_smiling_face:

P.S.:

I guess what Neviile meant with

is that you should try an x11 session instead of a wayland session.

suggests:

if I log out, and then click on my name to log in, and it opens the password field - then there, on the lower right, a toothed wheel appears and there I can select another session.

It should work, I think.

Thank you very much for the explanation, but unfortunately changing to Xorg (X11) didn’t solved the problem. is there anything else I can do?
