According to what you’ve posted there, the Nvidia modules are loaded and running. Hence the reason you cannot remove them as they’re in use.
So you performed a reformat/clean KDE Neon install, added the Nvidia Launchpad PPA, successfully installed the drivers - And you still cannot run anything intensive on the dGPU?
Yes, that’s correct. Only under X11 the nvidia card is shown to me under systeminfo.
Had this issue recently too.
TL;DR: Switch to an X11 session on the Kubuntu login screen.
Installation used:
sudo su
apt update
apt upgrade
ubuntu-drivers list
ubuntu-drivers autoinstall
prime-select nvidia
reboot
To check current GPU
glxinfo -B
Wayland is always falling back to the integrated GPU (Radeon 610M) no matter what I do, which is slow as heck.
X11 uses the Geforce 4070 dedicated GPU, no issues.
Will try again in 25.04
I have now checked again - the graphics card works under X11. I just had to set it as a priority and everything works. But unfortunately not under Wayland.
Hi, I’m having the same issue yet I’ve never installed the .run from Nvidia. My kinfo:
Operating System: KDE neon 6.3
KDE Plasma Version: 6.3.2
KDE Frameworks Version: 6.11.0
Qt Version: 6.8.2
Kernel Version: 6.11.0-19-generic (64-bit)

Processors: 8 × Intel® Xeon® CPU E3-1505M v5 @ 2.80GHz

Graphics Processor 1: Mesa Intel® HD Graphics P530
Graphics Processor 2: llvmpipe
Manufacturer: LENOVO
Product Name: 20EQS48H00
System Version: ThinkPad P50
I originally installed the Nvidia 550 driver with the ubuntu-drivers install command. kinfo showed the graphics card (M2000M) correctly until a recent update. I used the commands you mentioned:
sudo apt remove nvidia*
sudo apt purge nvidia*
sudo apt autoremove
I rebooted into a usual desktop (not a tty). kinfo then showed Graphics Processor 2: NV117. Then I did:
sudo ubuntu-drivers install nvidia:550
with llvmpipe showing back up in kinfo. I then enabled the Launchpad PPA you mentioned above and after doing the remove, purge and autoremove commands again, I installed the 560 & 570 drivers with the same llvmpipe showing in kinfo.
I also tried installing the libnvidia-egl-wayland1 package but it returns:
libnvidia-egl-wayland1 is already the newest version (1:1.1.17-0ubuntu0~gpu24.04.1)
Output of nvidia-smi:

Any help is appreciated.
I think devs need to get involved, this seems to be a KDE/Nvidia issue regarding switchable graphics solutions.
Unfortunately, I run a desktop PC with a dGPU and cannot test this issue any further. Sorry guys.
Yup, it needs to work out of the box like X11.
Most users are going to install Kubuntu, think “wow this is slow” with the default Wayland setup and move on.
