X11 issue on newly installed system

doghead66 · 2025-06-11 07:31:51

Recently did a fresh install but I have been having issues with X. I installed plasma kde and its working great through wayland but I can't seem to get the x11 version to start at all.
It might have something to do with the amd and nvidia card both in the workstation. I installed all the open drivers but don't have any of the closed source ones installed right now and no I am not using a display manager like SDDM (its installed but disabled).
When I try to run startplasma-x11 it returns $DISPLAY is not set or cannot connect to the X server.

if wayland works great, why do you want to get X11 working? Xwayland does not require a working X11 environment.

Next weeks Plasma update to 6.4 further splits the X11 dependencies into separate packages in preparation for droping X11 completely in some later update.

Have you done what it says in the Starting from console section here?

@BS86 if you look closely at the OPs post, you'll realize that this is not a problem w/ "plasma doesn't work on X11"
There's an obvious mistake in the OPs approach what, regardless of their motives, shifts the topic to "learn to read documentations and don't type random stuff into a shell".
Glancing over that by steering the OPs preferences is a disservice and will only result in the OP making worse mistakes on plasma/wayland.

Hey thanks for the replies although I agree I prefer Wayland and do typically use it I do have some specific software that requires an X11 environment no exceptions.
And yeah I did follow the commands to start it from console this way: https://wiki.archlinux.org/title/KDE
But when I do that method the desktop seems to be fully black with just my cursor showing. It looks like its trying to make windows since I can the frames but that's it.

software that requires an X11 environment no exceptions

for the most part is expected to run on xwayland (screenrecorder etc. probably aside)

when I do that method the desktop seems to be fully black with just my cursor showing… I can the frames but that's it.

I assume there's a "see" missing?
Please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General

When you get to the black screen with a mouse if you press ctrl + alt + t
It will be interesting if that actually opens a terminal I’ve seen that happen before when in the state you describe.

If it does open a terminal, try running:

plasmashell --replace

See if that does anything.

Otherwise can you share the journal logs from a session where this happened please?

doghead66 · 2025-06-11 20:19:01

yes there was a see missing sry I just woke up here is the log:

doghead66 · 2025-06-11 20:34:11

Tried to run plasmashell --replace in a terminal (the terminal was partially invisible) but unfortunately that did not seem to do much

Remove xf86-video-nouveau, your Ada chip isn't supported (actually all xf86-video packages aside maybe xf86-video-amdgpu)

[   104.554] (II) modeset(0): glamor X acceleration enabled on zink Vulkan 1.4(NVIDIA GeForce RTX 2060 (NVK TU106) (MESA_NVK))

Consider using the binary nvidia driver (though 575xx specifically has some serious issues right now) or see https://bbs.archlinux.org/viewtopic.php … 0#p2245680
Export either of those variables or make sure to have vulkan-nouveau installed

Wayland is running on the AMD GPU?

qdbus6 org.kde.KWin /KWin supportInformation

doghead66 · 2025-06-12 06:22:47

Removed all the xf86-video packages except xf86-video-amdgpu and yes when I run wayland it is running on the AMD GPU (its the main one I use the nvidia one I don't really use that often)
I also disabled zink and yes I have vulkan-nouveau installed but still having same issues with black screen

seth · 2025-06-12 10:53:04

What's the output of "qdbus6 org.kde.KWin /KWin supportInformation" in either context?

the terminal was partially invisible

What happens if you disable the compositor? (SHIFT+Alt+F12)

What happens if you run the X11 server on the amd gpu?
https://wiki.archlinux.org/title/PRIME#Configuration
(idk why it's even defaulting to nvidia, probably because the simpledrm inverting the cards - try to add "nvidia_drm.modeset=1" to the https://wiki.archlinux.org/title/Kernel_parameters - you should not have to use an Xorg config to steer the preferences.
Since you've one monitor attached to each GPU: you're looking at both screens in both environments, right?

There's one more thing, https://wiki.archlinux.org/title/KDE#Un … lution_set
Since xf86-video-amdgpu will rename the outputs, that might be an issue (but in that case you'd not see even a mouse cursor on one of the monitors)

doghead66 · 2025-06-13 08:06:43

Disabling the compositor (SHIFT+Alt+F12) "worked" but seems buggy I am getting visuals and can make new windows but it seems very laggy

doghead66 · 2025-06-13 08:14:40

Here is the output for the command qdbus6 org.kde.KWin /KWin supportInformation on the X session after I killed the compositor

The supportInformation make more sense w/ the compositor active, you can in doubt schedule them ("sleep 5; qdbus6 …") and toggle the compositor back on.

Have you btw. considered nvidia or nvidia-open instead of nouveau?

doghead66 · 2025-06-13 08:49:38

Ok I will try to grab that but honestly about the nvidia or nvidia-open thing I never really plan on using that gpu when I am just doing things on the system normally thats more for virtualization

doghead66 · 2025-06-13 08:57:48

Ok this one should be different:
https://pastebin.com/F9K8ebmj

doghead66 · 2025-06-13 08:59:15

I have not fully killed the nvidia gpu yet because I don't have anything setup that needs me to do that but I never really use it/want to for my actual desktop/kde

seth · 2025-06-13 09:17:39

OpenGL renderer string: zink Vulkan 1.4(AMD Radeon RX 6700 XT (RADV NAVI22) (MESA_RADV))

Please post an updated xorg log, do you still have the original issues?
What happens if you

export MESA_LOADER_DRIVER_OVERRIDE=radeonsi

Do you have https://archlinux.org/packages/extra/x8 … an-radeon/ installed?

doghead66 · 2025-06-13 09:28:24

I do have vulkan-radeon installed I will try to post an xorg log in a sec

doghead66 · 2025-06-13 09:36:42

Here this should be it:
https://pastebin.com/A8zEjSzP

doghead66 · 2025-06-13 09:39:55

as for issues with X currently I still can't seem to have the compositor running when I am using x11 kde

seth · 2025-06-13 13:15:09

It's gotten worse, you're now using zink on nouveau.

[    49.401] (II) modeset(0): glamor X acceleration enabled on zink Vulkan 1.4(NVIDIA GeForce RTX 2060 (NVK TU106) (MESA_NVK))

Because of the hybrid graphics, do NOT export MESA_LOADER_DRIVER_OVERRIDE but instead try "export NOUVEAU_USE_ZINK=0"
Also make sure to have vulkan-nouveau installed as well

Also you're currently (still) not running on the AMD GPU, https://wiki.archlinux.org/title/PRIME#Configuration - if you struggle to apply that to your system, please ask back.

doghead66 · 2025-06-16 05:55:00

I do have vulkan-nouveau installed tried using "export NOUVEAU_USE_ZINK=0" but now I can't seem to properly start the session at all.
I am a bit confused however with the prime solution would it be better to just disable the Nvidia card outright instead of having it do some of the work?

doghead66 · 2025-06-16 05:57:58

Because I pretty much never use it on my main system more just for passthroughs and what not
