Regarding the Qt based solution for file-browser
0)
I 'ssh -X' to my dev station from my pc. All the activity is happening in
my dev station.
1)
when I run my note-book with jupyter, I press a button and it expectedly
which launches a pop-up file-browser dialog.
2)
But when I run jupyter-hub and use python 2.7 kernel to run my notebook,
I press the button and the kernel dies with the error message "Cannot
connect to X-server".
Attached is the log for running jupyter-hub. Only the starting log is
shown, which shows how I may have started it.
-thanks
