Hello,
I’ve tried a fresh installation on an old AMD AM1 APU machine.
Both Arch and LTS kernels, Btrfs file system, HDMI connection to monitor, KDE Plasma, Wayland.
I asked the system to log me in automatically.
When I boot for first time, post installation, I see a login window. When I log in, the screen starts to glitch, shows strange colors at the top, flicks on and off and returns me back to the login window.
Login window appears as normal.
Any idea what to try next? Thanks
What is the exact hardware? You can either boot on the live ISO or get into tty and post the info. Have an internet connection also and post the url.

Edit: I’m assuming it’s an older Athlon processor or something in that era? Have you tried logging in under X11?
Your hardware:
Graphics:
Device-1: AMD Kabini [Radeon HD 8400 / R3 Series] vendor: ASUSTeK AM1I-A
driver: radeon v: kernel alternate: amdgpu arch: GCN-2 code: Sea Islands
process: GF/TSMC 16-28nm built: 2013-17 ports: active: HDMI-A-1
empty: DVI-D-1,VGA-1 bus-ID: 00:01.0 chip-ID: 1002:9830 class-ID: 0300
Your hardware is older radeon Sea Islands. Not sure if or how it works on Wayland. EOS is also using dracut so some of the instructions in the Arch wiki refer to mkinitcpio which don’t apply. I’m not an expert on this but i will give what i can. I would make sure you have the ati driver installed.
It is xf86-video-ati and i’m pretty sure it’s installed on EOS as default. I would try first logging in with X11 which can be switched at the log in screen bottom left corner of the screen.
Then follow section 2.2.2 in the arch wiki and set the kernel paramaters for sea islands. I’m not sure if you are using grub or the default systemdboot?

If you try logging into X11 first and let us know if that works or not? You may have to get into a tty to set some of these configurations.
Edit: This is a GCN2 chip so it should be supported by amdgpu.
creating the amdgpu and radeon confs and adding the options worked. System boots into wayland and x11. Thanks!
Excellent glad it worked. That’s why i wanted the hardware info to know if the gpu was a GNC version or earlier.
