Hi all,

I would like to know how can I set kdesudo environment PATH and LD_LIBRARY_PATH.
Thank you.

What do you mean by kdesudo environment ?

I mean everything you see when you do:
kdesudo printenv

I believe it follows the standard sudo configuration for this, as it simply provides a GUI for interacting with sudo.

Unfortunately, it doesn't have the same configuration, if you try sudo env, and then kdesudo env, you can see that i.e. PATH are not the same.
So my question is: where is the environment file for kdesudo? I tried /root/.profile , /root/.bashrc, /etc/environment, etc... but nothing.
Maybe the only solution is using ldconfig instead of LD_LIBRARY_PATH, and launching my GUI application putting the complete address after kdesudo.

Since kdesudo has root privilages, it is possible that it "cleans" the environment to protect the system aganist exploits by malicious users / software from crossing the user permissions barrier.

However, since kdesudo is a modified version of kdesu, I cannot confirm the above. You would need to ask the Kubuntu developer who created it.
