Just a far-fetched idea, but what if your display has a different name? Run the command w and look at the FROM column, see https://askubuntu.com/questions/230835/list-existing-x-display-names.

@kenneth.christiansen -- are you using a different shell than the default? Does this still reproduce if you restart?

No, regular shell. It is normally fixed after reboot but then later appears again (like after having been inactive for some time)

I switched from bash to zsh and also got this error. Once I manually set DISPLAY=:0 then I could start GUI apps.

if you're not using the default shell, see issue 828877 . that's not this bug.

Partly fixed, need to move socket to a new location which will also affect ARC++.
