[SOLVED]python3 app doesn't autostart in mate

[dancer_69]

I've created a python3 application which I use for a long time without problems. I already created an autostart entry which run without problems in cinnamon and also in xfce, plasma which I have tested before, in arch linux. I just installed mate yesterday, and even there is an entry for this application in autostart applications, it doesn't start when I login to mate desktop. I tried different things:
-use a script:

Code: Select all

#!/bin/bash
python3 /home/user/pysnoozeshutdown/main.py

-add a delay:

Code: Select all

#!/bin/bash
sleep 20
python3 /home/user/pysnoozeshutdown/main.py

-specify python3 path:

Code: Select all

#!/bin/bash
sleep 20
/usr/bin/python3 /home/user/pysnoozeshutdown/main.py

-add the command directly without script:

Code: Select all

/usr/bin/python3 /home/user/pysnoozeshutdown/main.py

Both the script execution and the direct command from terminal work fine and the application runs.
I alse have check the autostart folder in .config and the .desktop file is there and its contents change when I change something from autostart applications setting.
Is there something special that mate needs? Because there is no problem in cinnamon, plasma, xfce desktop environments.

Again, I found the problem minutes after created the thread
I opended the .desktop file and there wasn't an entry for Name and Description, but only Name[el] and Description[el](my native language translated entries). I didn't think that this was a problem because as I wrote above this file worked on cinnamon(which originaly created).
I checked the .xsession-errors file and I found an error parsing this .desktop file. So I remove the [el] from Name and then the application autostarted without problem.
