I'm using gnome 3.10 on ubuntu 14.04, with gdm as my default login manager. Also, numix-gtk-theme and numix circle icon pack.
For whatever reason, sometimes my system stops detecting wifi (even if it's already connected) and I can only reconnect upon rebooting. After one of those reboots, I logged in, but was presented with the grayish gdm background, without no further actions. All I could do (and I've done this extensively since then) was Ctrl + Alt + F1 and try some stuff out.
After some research, I noticed that:
startxworked at that particular session, but it was rather slow;- reinstalling, reconfiguring, both gdm and gnome-shell would do nothing;
- the only thing that seemed to fix my problem was renaming
/.config/dconf; after rebooting, it worked. Just now, though, I had to reboot again and the same problem happened. - I just tried adding a new user. It worked within the new user, but then I don't have any of the stuff I installed there.
Any thoughts? If you need further info, let me know and I'll edit accordingly.
