I am trying to run mbsystem (a command-line tool for geodata processing) that for some commands uses a GUI based interface (e.g. if i type 'mbedit' in the command line, a window should open where i can manually edit geodata). For this, i needed to install XQUartz but whenever i try the GUI, the error message 'Couldn't find per display information' occurs.
Xclock, xeyes, xterm all work fine, it's just in combination with mbsystem. I spend ages googling and trying a lot of things, Logging in and out, reinstalling, changing installation order etc. didn't work.
DISPLAY is set to
/private/tmp/com.apple.launchd.Ws5cVK5Ody/org.xquartz:0, setting it to localhost:0 or just :0 still throws that error.
I'm helpless - can someone give me a hint?
