Python 3.4.2
Tkinter 8.6
GCC 4.9.1 on Linux
I am working on a gui program using Tkinter. The program will
have a feature to restart as root. I am testing different gui
front-ends from a terminal to raise privileges and I want to
be able to use as many as possible for obvious reasons. Gksu,
kdesudo and su-to-root all work perfectly. However, I have a
problem with pkexec. Here is the command I am using from a
terminal:
$ pkexec python3 /home/user/Python/linfo-tk/linfo-tk.py
I get this error:
Traceback (most recent call last):
File "/home/user/Python/linfo-tk/linfo-tk.py", line 455, in <module>
root = tk.Tk()
File "/usr/lib/python3.4/tkinter/__init__.py", line 1854, in __init__
self.tk = _tkinter.create(screenName, baseName, className, interactive,
wantobjects, useTk, sync, use)
_tkinter.TclError: no display name and no $DISPLAY environment variable
The display environment variable is set:
$ echo $DISPLAY
:0.0
And the program displays and works perfectly in every other way.
I would appreciate any insight.
