In the past, Debian presented an action menu upon initial boot after install where you could confirm "login as root." When that option disappeared, I stopped defining the root user.
However I now need to be root user in gdm to use tools that work better graphically.
This is what I want to do:
1) Open the root terminal and enter my password.
2) Login as root
3) Exit the root terminal and do my thing as root.
4) Use the normal login to get back to my account.
My current work-around is to launch the apps from the root terminal. I have to do this for BOINC-Client to access the AMD gpu driver for some openCL apps.
When I try to do the same with Mathematica, I have to authenticate each time. I prefer not to do this.
The plan is to run BOINC as I am currently doing and shutting it down before I switch to root. After I switch back, I will relaunch it. It uses the same resources (the gpu) as the Mathematica project.
How can I do this?
