Its not a ram issue, well it doesnt look like it.
Ive got the window up, ive got it "running" xfce- an error box saying:

Unable to load a failsafe session
Unable to determine failsafe session name. Possible causes xconfd isn't running (D-Bus setup problem);
environment variable $XDG_CONFIG_DIRS is set incorrectly (must include "/etc") or xfce4-session is installed incorrectly.
