[SOLVED] weird display after migration to plasma 6

I just did today the migration to plasma 6 and it looks like the a regular (although big) update.

I was asked to replace some packages in the process (said yes to all of them) but after reboot, my system reached the graphical user interface but the display is clearly wrong.
Low resolution, huge mouse pointer, black desktop without any background, and some aplications do not open. Some others do but fonts are huge.

Here is the the journal output:

I guess I need to remove old config files from plasma 5.

Any help would be appreciated.

Thanks @Scimmia. After doing

sudo modprobe nvidia_drm modeset=1

and reboot, it seems that the value was not set properly as I got "N" when executing

# cat /sys/module/nvidia_drm/parameters/mod

How this value can be persistent?

Re: [SOLVED] weird display after migration to plasma 6

You need to set it on the kernel command line

For NVIDIA driver version < 545 or when not also using fbdev=1, the nvidia_drm.modeset=1 option must be set through kernel parameters, in order to disable simpledrm [1] (for more information, refer to FS#73720).

Thanks again @Scimmia.

I modified the kernel parameters by adding `nvidia_drm.modeset=1` to GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub, regenerated grub.cfg and rebooted into a nice looking plasma 6 DE.

I'll mark it as solved.
