Can't open gnome-terminal, natulius, gedit, clocks [duplicate]

I've had some problems after recent nvidia driver update to Ubuntu 17.10 (ubuntu on xorg) (Login loop after nvidia driver update) But I was able to fix the login loop by reinstalling nvidia drivers downloaded from nvidia driver page.

But problems with gnome-terminal, nautilus and gedit still here. I can't open any of them by clicking on icons (dash, dock). I can open gedit and nautilus from UXTerm but gnome-terminal shows this error:

Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: Timeout was reached

But

dbus-launch gnome-terminal

Works.

All those are running in the new user account I created.

I've tried reinstalling all of them, running

localectl set-locale LANG="en_US.UTF-8"

But none of them worked. Any way to fix this thing?

It seems your locale setting have not been saved. To fix this you can set them via the GUI dialog in settings which is actually pretty easy.

After that the applications should be back to normal.
