[SOLVED] SDDM unable to start

Nadhem · 2017-05-13 20:05:39

SDDM won't start, I tried deleting cache as well as deleting sddm.conf and reinstalling sddm but it didn't help me.I think this is the error and I can't find what it means

Auth: sddm-helper exited with 7

Please use code tags, rather than quote tags when pasting output.

What are the permissions on /var/lib/sddm?

ls -l /var/lib/sddm

drwxrwxrwx 2 sddm    sddm    4096 May 13 19:45 sddm

WorMzy · 2017-05-13 20:19:50

Sorry, that should have been

ls -la /var/lib/sddm

Thank you for using code tags, but please update your original post to use them too.

Nadhem · 2017-05-13 20:23:50

Done.
the output of

ls -la /var/lib/sddm

is

total 8
drwxrwxrwx  2 sddm sddm 4096 May 13 19:45 .
drwxr-xr-x 46 root root 4096 May 13 19:45 ..

Ok, so surprisingly enough my root partition was full.
I emptied some space and sddm is working again.
