Error: cannot open display: :0.0 [SOLVED]

Hi,

After my last reebot I've got some problem with Xorg. Everything goes ok, kdm starts, I can log in and...
On KDE I can't start any application(some parts of KDE doesn't start too(for example krunner)).
On fluxbox I can start only few apps(2-3). And when I try to start another one:

No protocol specified
Error: cannot open display: :0.0

Thanks for all advices.

Try either :

export DISPLAY=":0.0"

or

xhost +your-username

in the terminal, that is how I solved my problem.

P.S: if xhost +your-username doesn't work try

 xhost +

Unfortunately:

export DISPLAY=":0.0"

Doesn't change anything.

xhost ...

returns:

No protocol specified
xhost:  unable to open display ":0.0"

I didn't suspect NetworkManager...
