Portjail will not open x11 apps

[malco_2001]

When trying to run any app that requires x11 using portjail under gnome I get this

Ex. portjail run firefox

No protocol specified
No protocol specified
Error: cannot open display: :0.0

x11 apps will launch fine using the portjail run command under KDE.

Are you running portjail from the menu icon, or through some other
terminal / shell command that you've started manually?

when in kde i ran the command portjail run firefox under konsole the kde terminal app. when under gnome I used the built in gnome-terminal app and ran the portjail run firefox command.

I found the fix Kris. If I run the command "xhost +" in a terminal as a regular user under gnome it disabled access control for X11 which then allows me to run portjail run firefox under gnome. Now that I think about it I do remember reading somewhere that gnome has certain things like xnest support disabled out of the box whereas KDE has it enabled.

I stumbled upon this after also trying jexec to execute gui apps from the portjail. After it failed I searched for jexec cannot open x11 display and found the command xhost + to work around the issue.

I also noticed fluxbox has the same problem. Portjail only seems to run commands out of the box with KDE with those 3 window managers installed. I haven't tried any of the others lxde or xfce yet... For now I will just add the command to my startup applications under gnome to work around it. Hope that helps.

Ahh, that makes sense. If you are running the "portjail" command as your
user and executing apps as your user then typically that wouldn't be
required though.
