Issue: In TDE in MX18 (stretch) the MX Tools apps would open in TDE.

In TDE in MX19 (buster) the MX Tools that need to run as root will not open in TDE. The behavior is click the menu item and nothing happens (e.g. do not get any prompts for password).

MX Dev: “What does TDE Buster use to escalate permissions for their apps that need it?” “We did switch them to using a wrapper called mx-pkexec to keep the tools working on Buster after Debian removed gksu and went more to policykit-based privileges.”

IMO it's "tdesu"

Nik

This isn’t huge, really just an annoyance, as I can login to Xfce to run any of the MX Tools I need...

Example Menu Command: su-to-root -X -c mx-packageinstaller

Copied mx-pkexec, su-to-root, and other called items below.

I tried the example command, it seems to need a GUI, as it borks with 'wrong password' (when the root password is correct).

Any thoughts would be really appreciated.

Best, Michael
