Re: Can't log in to the GNOME flashback/fallback (no effects) session
all I can say it that, due to another problem I have been working on, I have been logging on and off of all 3 options (Ubuntu (default), GNOME Flashback, GNOME Flashback (No Effects)), all day without any issues.
Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.
