In other distros like ubuntu and debian when I want to access root pcmanfm I type in gksu pcmanfm when I press altF2. When I try this in Tumbleweed I get this error:
Failed to execute child process “gksu” (No such file or directory)
What do I need to do to get this to work?
Hi
Try, gnomesu, kdesu or xdg-su instead… eg;
xdg-su -c pcmanfm
Create an alias to one if gksu is what your use too.
Hi
Is see there is a gksu package in the GNOME:Apps repository as well…
https://software.opensuse.org/package/gksu
Thank you so much!! Is there that great a risk if I install gksu from the Gnome Apps repository? Seeing as I am still new to Opensuse I want to make sure I am not venturing into dangerous territory. 
Hi
No, just download the rpm and install. I would suggest creating a directory your user can access and then via YaST repositories, create a local directory (check the plain rpm box) as a repository, then when you get the odd rpm to install, pop them in there, do a zypper ref and zypper in <some_package>.
