I cant run any application, this shows me in terminal when I want to start some application:

chromium
No protocol specified

(chromium:1542): Gtk-WARNING **: cannot open display: :0.0

When I put this in terminal:

 xhost +local:root
No protocol specified
xhost:  unable to open display ":0.0"

A bit of a long shot, but what do you have in /etc/hostname? If that file doesn't exist, then it's not so much of a long shot ... create it.

Another wild guess: https://bbs.archlinux.org/viewtopic.php … 7#p1250667 - make sure you're not out of space.

Thanks a lot, this was the case.

Please remember to mark the thread as solved https://bbs.archlinux.org/viewtopic.php?id=130309 (you need to shorten the title a bit).

I have the same problem, but adding a hostname file in etc doesn't fix anything.

Changing my host name fixed it for me. Instructions here: https://bbs.archlinux.org/viewtopic.php?id=153070

Is your system up to date?
Are the error messages exactly the same? Are you trying to start an Xserver app from tty?
