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:
startx
worked 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.
Uncheck the option to change wallpaper on start in Variety, if it is checked. Check if this fixes the problem.
Edit the file ~/.config/variety/scripts/set_wallpaper - this is the script that runs on every wallpaper change. Comment out all lines that are not applicable for your system - e.g. sections for XFCE, Lubuntu, etc.
But what you see might be some side effect of the wallpaper being changed in some unfortunate moment during startup, e.g. compiz loading the CPU/GPU, causing some race condition in a completely different process, etc.
If the suggestions above make a difference, please make sure to report back. Thanks.
