I found the following solution to use idle on the raspberry pi
as sudoer (which is necessary or at least comfortable when programming the
GPIO)
1. Open a terminal
2. type cd ~/Desktop
3. type touch idle_as_root
4. type nano idle_as_root
5. type in sudo idle
6. exit nano
7. type in sudo chmod +x idle_as_root
8. Close terminal
9. Double click on the idle_as_root program on your desktop
This all works fine as long as I use X, however
I also want to use it via vnc
For vnc I did the following:
Installed script "tightvncserver" on the RPiwith the following contents:
#!/bin/bash
# /etc/init.d/tightvncserver
VNCUSER='pi'
case "$1" in
start)
# su $VNCUSER -c '/usr/bin/tightvncserver :1'
su -l $VNCUSER -c '/usr/bin/tightvncserver :1'
echo "Starting TightVNC server for $VNCUSER "
;;
stop)
pkill Xtightvnc
echo "Tightvncserver stopped"
;;
*)
echo "Usage: /etc/init.d/tightvncserver {start|stop}"
exit 1
;;
esac
exit 0
sudo chmod 755 /etc/init.d/tightvncserver
sudo update-rc.d tightvncserver defaults
when starting the script manually like this
sudo /etc/init.d/tightvncserver start
everything works as expected i.e. I can click on the idle_as_root-icon and
it works as expected.
If however I reboot the system, the service does start and I do see the
rpi-desktop but clicking the idle_as_root-icon doesn't work. Manually
trying to start it as follows show an error:
pi@raspberrypi ~ $ sudo idle
Client is not authorized to connect to ServerTraceback (most recent call
last):
File "/usr/bin/idle", line 5, in <module>
main()
File "/usr/lib/python2.7/idlelib/PyShell.py", line 1427, in main
root = Tk(className="Idle")
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1712, in __init__
self.tk = _tkinter.create(screenName, baseName, className,
interactive, wantobjects, useTk, sync, use)
_tkinter.TclError: couldn't connect to display ":1.0"
Does someone here have a solution for this problem?
thanks in advance
