Black Screen Ryzen 2500u Vega 8

Hello, I'm trying to install plasma KDE on an HP EliteBook with Ryzen 2500u + vega8. Doing all the upgrades and installing the Amdgpu driver the system won't boot on graphics. If I set nomodeset, it comes on, but it has flickerings, hangs, and the main-> you can't change the screen resolution (1024 instead of 1980). I followed the below wiki

https://wiki.archlinux.org/title/HP_EliteBook_745_G5
At the initial installation and after installing the amdgpu driver, I had 3D acceleration (running games on Steam). With nomodeset I cannot play (obviously I have no acceleration)
I am out of ideas...How can I proceed?

What exactly did you "installing the amdgpu driver" ? You generally shouldn't need to install anything here. If you installed amdgpu-pro that will have been a mistake and you need to remove that.

I installed  xf86-video-amdgpu,  vulkan-radeon,  lib32-vulkan-radeon,  libva-mesa-driver, lib32-libva-mesa-driver, mesa-vdpau and  lib32-mesa-vdpau packages. After restart i have no graphics (black screen). Also ctrl+alt+f1 or 2 or 3 (TTYs) not working.

After such a failed boot, boot with nomodeset, login as root to a tty console .

run

# journalclt -b -1 | curl -F 'file=@-' 0x0.st

.

It will upload the journal of the previous boot and output  a link to the upload.
Please post that link .

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Now I noticed that after 3-4 reboots (alt+ctrl+del) and random selections fallback and normal mode, the system loads graphics correctly. It is very strange. Maybe it is a Dracut incompatibility?
