how to run an "on-click" command as root #791

Closed udaemon closed 4 years ago

udaemon commented 4 years ago

Hi, I was not able to figure out how to run a command as root when a module is clicked. to be precise, I want to start cpupower-gui when I click the icon of the cpu module, but neither "on-click": "sudo cpupower-gui" nor "on-click": "swaymsg exec sudo cpupower-gui" work. I shall mention that I even need to add the option -E or -EH to sudo: "on-click": "swaymsg exec sudo -EH cpupower-gui".

cpupower-gui needs to be granted root privileges in order to apply any changes.

any hint is very welcome. thank you!

Is your sudo passwordless, or did you remember to make an exception for these commands in /etc/sudoers? I would guess if you look at htop you would see sudo cpupower-gui pending there waiting for you to enter password...

thanks, maximbaz, that could be the right hint: while i have put a sudoers exception for cpupower I haven't for cpupower-gui... will try when I'm back home from travelling.

to provide a final report on my question: it took me a while to understand that this is rather a polkit-issue, i. e. to grant certain permissions on another level than within the terminal-root-realm. and with the help of this comment I was able to solve my issue resp. answer my question.

i had the same situation, i followed the same comment but did "on-click": "pkexec cpupower-gui" instead of "on-click": "sudo cpupower-gui". in case anyone reads this thread in the future
