hi
i took my lunch and tried the wifi pc again and xclock worked and x.py file opened with out any problems, so i’m thinking it something going on in the pc i ssh from and not to pc i’m ssh into.
actually g_network is an bash sh file that looks like this :
#!/bin/bash
cd ~/.my_tools/net_work
python network_button.py
exit 0
so i went to yet another um 16.04 wired pc , updated it. i changed it from static ip to dhcp rebooted and still the same thing .
