su-to-root is a simple script to give an interactive front-end to su. It can be used in menu entry commands to ask for the root password. …
I came across this utility while tracking down a problem in an installation of Linux Mint Debian Edition, where launching synaptic from the menu as user would silently fail. Synaptic itself ran fine from the terminal as root, so I looked at the relevant .desktop files.
locate -i synaptic | grep desktop found three files. Viewing them I saw that Exec= of two of them were synaptic-pkexec while one of them was su-to-root -X -c synaptic. I changed each instance of the former to the latter. Problem solved.
