[solved]starting gui gtk/qt applications problem

I am using xfce, after last update I cannot start qt or gtk applications, or use some system stuff like restart computer from menu.
Firefox, viber and qBittorrent are working.

These are outputs of some.

Re: [solved]starting gui gtk/qt applications problem

Have you been doing something like `sudo startx`...?

No. I am using same setting as before update.
Automatic log in, and automatic startx (without sudo) afterwards.

Re: [solved]starting gui gtk/qt applications problem

How do you login to your system?

Do you use a DM or startx?

Let's see whether my jedi senses still work ... ;-)

cat /etc/hostname

You're probably using networkmanager for network configurarion?
