On CentOS 7, what’s the best way to start a GUI program as root without a terminal? I mean, from a launcher or similar where you can’t provide terminal input to “sudo”. I’m talking about applications that aren’t configured to switch to root out-of-the box, of course.
I just tried gksu-polkit from EPEL, and it kind of did the job but:
1. It consumed *a lot* of resources – CPU usage was reported at a
constant 100 %, more or less.
2. The process did not go away after I closed the application.
Which means it’s practically unusable, unless someone can provide a way to fix these problems.
