Unable to launch window apps as root in Kwin

[uggla]

I'm trying the Kwin flavour but I have problems launching any gui-applications as root. Fex. sudo leafpad gives me "No protocol specified" "leafpad: Cannot open display:"

Hi uggla! I apologize for not answering before now, but I wasn't notified of your question...I wasn't ignoring you.

Thank you Adarsh for answering.

uggla, like Adarsh, I don't have the issue, and I can't recreate it...on neither kwin nor openbox. Was this on a fresh installation, or did you happen to modify anything after installing it/them?

I'm only asking out of curiosity since you've already solved the problem.

Thanks,
MiyoLinux

The problem is the same with the latest Openbox flavour too. :(

Is it on pcmanfm or on all application? I am using it and not facing the issue

I solved it by adding the following line to ~/.bashrc

xhost +si:localuser:root
