I have been in the habit of having an icon for RootPCManFM in the panel for LXDE. It is there because, sometimes I wish to add new wallpapers to /usr/share/LXDE/wallpapers. Having downloaded them (as normal user), they are held in /home/jim/Downloads. But if I want to copy and paste into the above mentioned folder, I need to use PCManFM with root privileges.
When I go to /home/jim/Downloads using RootPCManFM, I get the message, Permission Denied. OK, I guess it is just warning me that I am snooping around my /home folders with, potentially damaging root privileges. I click on OK and carry on to copy the file.
Then, when I go to back out of /home/jim/Downloads with the copied file, I get Permission Denied again. Click OK and I can then carry on to paste into the relevant /usr directory.
I was just wondering if LXDE has this as a safety warning feature. The same warning doesn't appear when using KDE. By the way, in the panel, I use a different icon for the Root file manager from the black file manager icon. I chose a brown cube from Utilities to save confusion.
I am getting to like LXDE more and more as I now use it fulltime on the laptop.
