Boot goes to X-Windows login screen instead of Xfce

My default desktop environment is Xfce 4.7 (older machine). Monday I came back to work to discover a 17 GB log file in /var/log that ate up my root partition and gave me trouble running. I deleted it, which solved the problem EXCEPT that now when I boot, instead of the Xfce login prompt, I get an X-Windows login prompt. This takes me to a terminal (which apparently reads my .zshrc file), from which I can start an Xfce session by running xfce4-session. How can I get back to booting into the Xfce login screen?

Thanks, and also I probably won’t be able to get back to you until tomorrow.

Don’t suppose you peeked at that 17 gig log to see what was throwing all those errors?? Note you can use less command to look at huge files. See man less.

Yeah, I should have posted it in the original. Anyway, this is the tail (all the errors were the same):

I wasn’t very successful in searching for what this could mean or how it’s connected to my problem.
