[Nearly SOLVED] Permissions in Thunar

[AustinTexas]

You should not be making that change in /etc/sudoers
/etc/sudoers gets modified occasionally (upgrades - depending on how you do your upgrade) and you will lose your edits.
You will notice that the last line of the /etc/sudoers file is:
#includedir /etc/sudoers.d
The proper way to add "user  ALL=NOPASSWD: /usr/bin/thunar" is to open leafpad as root:

Code:

gksudo leafpad

Add your line to the new text document, save as /etc/sudoers.d/personal (You can name the file anything you like.)
In order to function correctly, the file has to have the correct permissions, so enter the command:

Code:

sudo chmod 0440 /etc/sudoers.d/personal

Also, if you mess up, you just delete your personal file, and sudoers remains intact.
Find the instructions here:

Code:

sudo cat /etc/sudoers.d/README
