Linux won't boot after new video card

Hi. I just bought a new video card AMD RX6600 and my linux installation won't boot. I previsouly used the integrated graphics in the CPU (AMD Ryzen 5 3400G).

The steps are in order:

1. Press the power button
2. Choose 'archlinux' from the GRUB screen. Note: the windows installation is working fine.
3. Type in cryptroot password
4. After some text, all I get is a black screen with a flashing "_"

I never get to see the lightdm greeter. I took off the video card so I can boot in arch again.

Can anyone point me in the right direction?

Re: Linux won't boot after new video card

Check whether you can switch TTYs and if you can post

sudo journalctl -b
cat /var/log/Xorg.0.log

if you can't reboot and add to your kernel parameters, which should boot you to a terminal and post the same outputs but add -1 to the journal command. … n_services

Some other general suggestions, enable early KMS for amdgpu: … _KMS_start
