Hello everyone,

I’m writing to you because I’m having trouble with my screen. I’m on a laptop, and when I plug in an external screen it’s not detected:

I tried reinstalling the nvidia drivers and testing different ones, but nothing worked…

I’m convinced it works because I have no problem using this screen when I log on with my Windows session.

Does anyone have any tips for me? Thanks in advance for your help!

Have you tried an X11 session? (On the login screen, click the gear icon in the bottom right corner, and select “GNOME on Xorg”.)

3

It’s weird, I can’t. I enter my password and immediately return to the login screen… It won’t open the desktop in Xorg mode

4

That’s definitely not how it should be. You could check the log files in ~/.local/share/xorg and
journalctl -b0 --user-unit org.gnome.Shell@x11.service --user-unit gnome-session-manager@gnome.service

5

It felt like it was discussed 1 million times here and also on the big wide internet. In order to use the monitor output of the Nvidia graphics card on a hybrid system with Intel/Amd + Nvidia, you have to switch to the Nvidia driver. See optimus-manager or envycontrol, or create your own Xorg configuration. This is a limitation of the proprietary Nvidia driver, which is not compatible with open source drivers here, to put it bluntly.

6

See the “hybrid” mode of optimus-manager, for example; that won’t entirely switch over to the nvidia gpu, in fact, all rendering will still be done on the integrated gpu. Also, I am not sure that external monitors shouldn’t work on Wayland out of the box.

They are not using the open source drivers, are they?

7

I must correct myself. GDM still disables the wayland session when a hybrid configuration is detected. I thought this had changed since the last time I checked.

@LeoVitorino But then I wonder how you could log into the wayland session in the first place.

8

What you call hybrid is just the default setup. It runs on the iGPU, and you can switch GLX to Nvidia on demand, but you don’t have access to the monitor port of the nvidia card here.

No, it won’t work since nvidia doesn’t run with KMS by default.

nvidia → modesetting = nvidia output available :white_check_mark:
modesetting → nvidia = nvidia output unavailable :x:

The reason is simply that:

The NVIDIA DRM KMS implementation does not yet register an overlay plane: only primary and cursor planes are currently provided.
Chapter 36. Direct Rendering Manager Kernel Modesetting (DRM KMS)

9

I am pretty sure external monitors work in hybrid mode. I have used external monitors multiple times myself in the “hybrid” mode.

Hi,

11

you’ve switched to X11-session and nvidia-gpu as adviced ?
please post the output of

echo $XDG_SESSION_TYPE

and

glxinfo | grep server

you’ll need to install the package “mesa-utils” if glxinfo isn’t avaiable

12

Hi @Olli ,

I can’t switch to X11-session, Every time I try, I immediately go back to the login screen…

I confirm that I’m on a wayland session. And the output of glxinfo | grep server is :

server glx vendor string: SGI
server glx version string: 1.4
server glx extensions:

thank you for your help !

Léo

13

i’m not an expert at gnome while using plasma but as far as i know a config entry should be defined at gnome.
please try this

cat /etc/gdm/custom.conf

does it exist ?
then reuse it and search for Wayland

cat /etc/gdm/custom.conf | grep Way

what is displayed ?

14

For your first command, this is what i got :

# GDM configuration storage

[daemon]
# Uncomment the line below to force the login screen to use Xorg
#WaylandEnable=false

[security]

[xdmcp]

[chooser]

[debug]
# Uncomment the line below to turn on debugging
#Enable=true

Isn’t that weird?

15

we’ll that’s okay and as you can see you’ll have to uncomment the line

#WaylandEnable=false

to

WaylandEnable=false

you’ll need to edit with sudo rights. kate is a good choice.
after editing and succesful saving please post the output of

cat /etc/gdm/custom.conf

again. please post if you did it

16

OK, I changed it, but now I can’t start manjaro (I can’t reach the log screen) … I think I’ve to reinstall completely manjaro…

17

can you login at console with ctrl-alt-F5 ?
also turn on the second display at boot.

18

Yes I can access to the console!

19

please login at console and use

sudo systemctl restart gdm

any error messages, booting. please report what happens

20

I still have a black screen, just a “_” on the top left side

So I revert the changes and now I can go again on the connexion screen
