[Solved] Display Manager (GDM and LightDM) Failing on boot

Hi All,

I'm fairly new to Arch and encountered an error today while booting the system. Apologies if this should be in Newbie Corner instead.

On loading the Display Manager I get a White Screen saying 'Oh No something has gone wrong'.

I can log into a different tty to get the logs.

dmesg
https://pastebin.com/9nBNRf62

journalctl -b
https://pastebin.com/hvGxPjXS

My suspicion is the following section in the journalctl is causing issues

To try and resolve this I've run pacman -Syu as well as fully uninstalling gnome and all dependencies (gdm included) then reinstalling as well as installing plasma instead neither of which has worked.

Thanks in advance for any help!

Edit: you're on 5.10.16-arch1-1
If you did "pacman -Syu" there's either a problem w/ your mirror, you're using some arch derivate or you ignore packages in pacman.conf?

Re: [Solved] Display Manager (GDM and LightDM) Failing on boot

Hi,

Thanks for the quick response and apologies for the delay was away from the computer yesterday!

Looks like the issue was to do with a partial upgrade as per the post you linked. I was stupidly not paying attention to the pacman -Syu logs which was erroring out due to conflicting dotnet versions (and then a dependency chain if trying to remove the conflicting package).

Uninstalling the dotnet package via:

pacman -Rcns dotnet-runtime-bin

and all dependencies then running pacman -Syu again has fixed the issue.

Thanks again for the help!
