Now I'm the idiot. I may have had an ADHD moment and been distracted, but I have a similar problem, and using "pcmanfm --desktop-pref" in CL doesn't do much for me. Brings up the appropriate menu, but with a number of debug mssgs in CL, and when I try to apply any change, I get this mssg in CL:
(pcmanfm:1804): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.O96VBW': No such file or directory
I have recently returned to Unix/Linux after a couple of decades, so I am sort of rebooting my knowledge base. I can say, I think, that this ain't what I want to see, so any suggestions/comments would be helpful, and if you want to chuckle first, that's just fine, since that's what I did.
Also, if this should be posted, or reposted, in another forum section, let me know where and I'll get it done.
