I did what you said but I did got some errors. But after some searching I think I got it right.
(I did see now that you already have edit your post, so I got it right)
Code:
thaiice@thaiice-MS-7721 ~ $ cd /home/thaiice/
thaiice@thaiice-MS-7721 ~ $ cd .config/
thaiice@thaiice-MS-7721 ~/.config $ sudo su
[sudo] password for thaiice:
thaiice-MS-7721 .config # chown -R amnesia:amnesia autostart/
chown: invalid user: ‘amnesia:amnesia’
thaiice-MS-7721 .config # chown -R thaiice:thaiice autostart/
thaiice-MS-7721 .config #
and then
Code:
thaiice@thaiice-MS-7721 ~ $ ls -ld .config/autostart
drwxr-xr-x 2 thaiice thaiice 4096 feb 8 22:31 .config/autostart
thaiice@thaiice-MS-7721 ~ $ ls -l .config/autostart
total 372
-rwxr-xr-x 1 thaiice thaiice 368928 feb 8 22:31 knemo

thaiice@thaiice-MS-7721 ~ $
Now when I will go to this folder I will not see the "lock" picture on the folder.
Thanks.
I would like to understand more of Linux. But I don't know of anyone else here (in this small city where I live), who are using Linux, so it is only when I have problem for my self, that I get some exercise, and that is not many times now, (Linux is already so good system

)
Now I can add the KNemo using the 'Startup Programs' (so I just remove the program from the autostart folder, still having the knemo.desktop entry there).
Code:
thaiice@thaiice-MS-7721 ~ $ ls -l .config/autostart
