Mistakenly filled up 100% of /dev/root, can no longer start xsession as non-root user

I was installing packages from SBo when it said that I ran out of space halfway through. Running df, it said that 100% of my /dev/root has been used up. So i tried removing some of the packages I just installed but apparently that didn't bring it down by even 1% which is strange.

For some reason, I can start an x session as root but whenever I try to startx as a non-root user, it says it doesn't have enough space to make a log file;

Code:usr/bin/startx: line 188: cannot create temp file for here-document: No space left on device
usr/bin/startx: line 205: cannot create temp file for here-document: No space left on device
usr/bin/startx: line 205: cannot create temp file for here-document: No space left on devicethen later down the screen it reports:
