Okay. I thought it might have something to do with PCManFM.
I know you don't want to hear this. But, it will probably save you some grief in the long run. Please understand, I am not casting any aspersions on someone who is no longer here. I think Melodie meant well, but she failed to follow the tried and true PCLinuxOS "formula" in her quest to slim down the desktop environment. She removed vital python packages.
If it were me, I would start over and install Leiche's 2012.01 LXDE Mini edition
. Believe me, you won't use any more resources than you would with the "pure" Openbox desktop. And, man, is it fast
! No exaggeration. You'll have the advantage of using a fully supported desktop environment. Openbox is in limbo, right now. The Openbox CDs are no longer listed on the main site
Just remember to install the apt-sources-list
package before updating and installing packages.
EDIT: Melodie has informed me she did not
add any custom packages. I believe her.
