[Solved]Cosmic boot error

I removed Cosmic Desktop, but I get these errors during boot

Xfce works normally.
How do I fix the errors? Thanks

Re: [Solved]Cosmic boot error

Then how is it running?

pacman -Qs cosmic

Also nb. the snippet you posted is from 2 days ago.

Please post your complete system journal for the boot:

sudo journalctl -b | curl -s -H "Accept: application/json, */*" --upload-file - 'https://paste.c-net.org/'

Re: [Solved]Cosmic boot error

I solved the problem by manually deleting some Cosmic files that hadn't been uninstalled.
Thanks for your help.
