Hi, replaced my gpu, and I cant see the lightdm login page when I boot on manjaro now. I think the right driver is installed, I was able to do ctrl alt f+number to access a terminal and I did the command I saw was recommended on the wiki for mhwd (sudo mhwd -a pci nonfree 0300) but it said the right driver was installed, I could not start lightdm but just starting “sway” (the i3 wayland window manager) worked, I moved my x configuration files (etc/x11/) and left it empty and then I was able to start lightdm from one of the tty after rebooting though it is in qwerty mode and I use an azerty keyboard, I was able to log in normally and the system seems to behave mostly fine, pulseaudio is not working. I have no idea what log is needed. Thanks for the help. system info
Hi @gtrjrkjrfkdk,
You’ve definitely got mixed up drivers there. Please provide the output for:
mhwd --listinstalled
And
mhwd --list
Tip:
To provide terminal output, copy the text you wish to share, and paste it here, surrounded by three (3) backticks, a.k.a grave accents. Like this:
```
pasted text
```
This will just cause it to be rendered like this:
Portaest sed
elementum
cursus nisl nisi
hendrerit ac quis
sit
adipiscing
tortor sit leo commodo.
Instead of like this:
Portaest sed elementum cursus nisl nisi hendrerit ac quis sit adipiscing tortor sit leo commodo.
Thereby improving legibility and making it much easier for those trying to be of assistance.

I dont know if its relevant but I had to install a specific nvidia driver recently as I had issues with xrander Xrandr can no longer find my second monitor - #2 by megavolt
That’s definitely not the right driver for your new card. Remove it and reboot.
sudo mhwd -r pci video-nvidia-470xx

Well, to start with, if you’re replacing the nvidia with an AMD, as your title says, then the nvidia drivers’ll do you no good. So you can remove them:
mhwd --remove pci video-nvidia-470xx
Followed by rebooting.
I removed video-nvidia-470xx rebooted and still the same issue, black screen, my monitor shows a message saying there’s no signal and I start lightdm with a terminal I accessed by doing ctrl alt f number

OK, let’s try removing and reinstalling the driver, then.
To remove it:
mhwd --remove pci video-linux
And then, as per the Wiki, install the free drivers again:
mhwd --auto pci free 0300
Then reboot again, and see.
* mhwd --remove pci video-linux

I rebooted, then maybe it was a blip but I got a black screen when grub should have come up, rebooted again, grub reappeared, and no change from previous situation, black screen.
In that case, let’s check the logs. In a terminal, run and provide the output of:

Can you try putting those files back?

Or else, try reinstalling lightdm:

I put the files back, lightdm does not start after grub, and also I cant start lightdm from one of the ctrl alt f+number terminal but sway works (sort of).
Well, I honestly have no idea further then, except possibly forcing to overwrite conflicts on reinstall:
pamac reinstall --overwrite lightdm
that command is not working for me
pamac reinstall --overwrite lightdm
Reinstall packages
pamac reinstall <package(s),group(s)>
options:
--overwrite <glob> : overwrite conflicting files, multiple patterns can be specified by separating them with a comma
--download-only, -w : download all packages but do not install/upgrade anything
--as-deps : mark all packages installed as a dependency
--as-explicit : mark all packages explicitly installed
--no-confirm : bypass any and all confirmation messages
Hmmm, the only other thing I can think of is:
pamac reinstall lightdm --overwrite /etc/*
If that doesn’t work, I have NO idea further.
