i have gnome-tweak tool running on a install of Debian 8 with gdm3 installed, how do i allow this application to run with full permissions? When i run "sudo gnome-tweak-tool" the program runs as expected, but when i try to run some programs from the applications menu or just using the app name without sudo from terminal, there are problems. With gnome-tweak-tool it runs but it's not possible to change anything, and it opens with a theme different to the system theme. I don't have this problem on Ubuntu gnome, could someone please explain why that would be, what am i missing, how do i fix it without adding sudo or gksu to the exec line of every .desktop file?

This is what i expect to happen:

Here's what's actually happening without running with sudo from terminal:

There was a problem with gnome install.

I ran these commands in the terminal;

sudo apt-get --reinstall install gdm3 -y
sudo apt-get --reinstall install gnome -y
sudo apt-get --reinstall install gnome-shell -y 

Now gnome-tweak-tool works fine when launched from the applications menu.
