Title: zenity hangs & .desktop files dont have the desired effect

Environment: Ubuntu Oneiric x64, gnome-shell, zfsonlinux

Motivation: Automagically save state of all VM's (and config) while virtualbox doesnt get in the way.

Approach: Use a bash script to do that (snapshot filesystem before starting virtualbox GUI and after it is closed).

Additional Detail: This basically is a One-User-System, and i allowed sudo for zfs commands to myself.



Problem(s):

+ The (zenity)-notification sometimes stays invisible and hangs the script. Thus the "workaround" function. [edit:] This one is better done using the first answer below. I changed the script to reflect that and had no hang since.

- Although the script seems to work (its only used by myself, no multi-user requirement), i was unable have it in the launcher. [edit:] No solution until now.



Failed tries:



Problem 2:

- create .desktop-file, validate it with desktop-file-validate, install with desktop-file-install, reboot => still not there although i installed to the recommended directories. I also used the suggestion from below to no effect.



Problem 1:
