Cannot prevent XFCE from saving session
I saved a session once, and decided I didn't want a saved session. In Session & Startup, I unchecked save session on logout and deleted all sessions. XFCE continues autosaving the session on logout, and auto-starting it on login.
I know I can hack ~/.cache/sessions/ to be read-only, but that is a workaround. I might want to save a session in the future, so this is not a solution.
BTW, I found that after deleting all sessions, ~/.cache/sessions/ still existed and contained a thumbnails folder. Doing rm -rf ~/.cache/sessions got rid of it, and now it doesn't load. But a manual step mucking around on the command line should not be required. And how was it loading a session from thumbnails? I didn't look inside the thumbnails folder before deleting it so can't offer any more insight on this odd behavior.
