Comment 62 for bug 291467

Still having the same problem but there's one behaviour which seems odd to me. Disabling services in Preferences/Sessions makes the appropriate changes to my /usr/share/gnome/autostart scripts, but every time I boot the default sessions are being written to ~/.config/autostart - including two more references for PulseAudio.

Aside from the fact that the only way I can get Bluetooth drivers to stop loading is to uninstall them, is there a chance that the double entries for starting desktop services are conflicting, and if so, how would one turn them off?
