[SOLVED] Black screen with only a blinking cursor - rx 6600 xt

When i first installed my rx 6600 xt using linux 5.13.10 i had a black screen with only a blinking cursor in the top left corner of my screen (tty2 works).

yay -S linux-git

to 5.14-rc7 fixed the problem. Now i decided to upgrade to official 5.14.2 but still same problem.

sudo dmesg|grep -i amdgpu

between the kernels shows no difference. Maybe a different kconfig between the builds?

System
B550, 5600x, rx6600xt
yay -S mesa-git:

local/lib32-mesa-git 21.3.0_devel.144661.fb5deb2b4a0-1

yay -S lib32-mesa-git:

local/mesa-git 21.3.0_devel.144661.fb5deb2b4a0-1

official linux-firmware:

local/linux-firmware 20210818.c46b8c3-1

Could be KMS detection race, especially if switching VTs fixes it -> https://wiki.archlinux.org/title/Kernel … _KMS_start

If that doesn't help post a journal of a faulty boot

sudo journalctl -b

and maybe a xorg log if something graphical is supposed to autostart.

Thanks:

$ sudo gedit /etc/mkinitcpio.conf
changing MODULES=""
to MODULES="amdgpu"
$ sudo mkinitcpio -P

fixed the problem
