Ok, so I edited Grub in
/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet apparmor=1 security=apparmor udev.log_priority=3 amdgpu.dc=1"
and
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES=(piix ide_disk reiserfs)
MODULES=(amdgpu)
Then successfully regenerated the image with:
sudo mkinitcpio -P
but that didn’t help yet @Olli
