Hi, Just installed NixOS with Plasma 6 as the desktop environment. The bootable usb drive worked no problem. Now when I start the NixOS it boots straight to the tty.
Installed on a Lenovo Laptop with a 4500U “APU”. I’m assuming this is from a gpu driver issue.
I ran journalctl --boot -e
and scrolled to the top to find the first error which is:
date nixos kernel: [drm] psp gfx command LOAD_TA(0X1) failed and response status is (0x7)
date nixos kernel: [drm] psp gfx command INVOKE_CMD(0x3) failed and response status is (0x4)
date nixos kernel: amdgpu 0000:04:00.0 amdgpu: Secure display: Generic Failuer.
date nixos kernel: amdgpu 0000:04:00.0 amdgpu: SECUREDISPLAY: query securedisplay TA failed. ret 0x0
date nixos kernel: amdgpu 0000:04:00.0 amdgpu: SMU is initialized successfully!
the next error is when loading sddm, couldn’t setup default cursor, then another error with sddm is something about locale “c” character encoding. Then some error with qt.dbus.integration. So many other errors. Final error is:
date nixos kwin_wayland[1022]: kwin_wayland_drm: Atomic modeset commit failed! Permission denied
date nixos kwin_wayland[1022]: kwin_wayland_drm: Setting dpms mode failed!
I’m then presented with the login at a tty.
Any help would be much appreciated.
Thanks.
