Xorg permission-Issue - only root can start gui-programs

Hello,

today I installed a fresh Arch Linux. Base-system, xorg and i3. I can launch i3 as normal user - everything is fine. And I can e.g. start alacritty. But I cannot start any program with graphical frontend.

Examples:
firefox: Error: cannot open display: :0
thunar: (thunar:8401): Gtk-WARNING **: 15:52:34.757: cannot open display: :0
libreoffice: /usr/lib/libreoffice/program/soffice.bin X11 error: Can't open display: (...)

As root I can start the above programs though. So supposedly it's a permission-problem. Any idea how I can solve these problems?

Thanks!!

Ps.:  I noticed, that I can e.g. start qutebrowser without problems as normal user.

How are you launching i3?
What's the output of hostnamectl?

Via startx. I testet it with an emtpy .xinitrc except "exec i3".

Output of hostnamectl:

Static hostname: standrechner

      Machine ID: x
         Boot ID: y

I testet it with an emtpy .xinitrc except "exec i3".

The empty .xinitrc is likely the reason for the issue.
Check https://wiki.archlinux.org/title/Xinit#xinitrc and create a proper .xinitrc .

Sadly, that doesn't help either. Actually the first try was a copy of an old .xinitrc from another installation before trying the empty one. Creating a new one as stated above results in the same behavior...

Please post the output of the following (from alacritty in the running i3 session):

echo $DISPLAY
stat ~/.Xauthority
find $HOME ! -user $USER
