After upgrading to Xubuntu 15.10 (I should write a section for this experience as well) I got aware of all my old sessions I stored to play around with different auto-start configs.
First question in mind was “Where are those sessions stored?”, second was “How to modify them or remove the ones I don’t need/like anymore?”.
Well, first I remembered about
$HOME/.cache/sessions directory – and viola – here they are listed in some cryptic file names…
Anyhow – sorting the output with
# ls -ltr you get very easy a clear picture what you should look into more deeper.
xfwm4-26aa58002-86b5..state xfwm4-2116f077f-59d9..state xfwm4-29fe00e82-36f8..state xfce4-session-
is the look and feel of my directory.
Either you delete all the files including the thumbs directory or you look inside the
[Session: Default|Whateveryournamewas] for each individual session.
