So I stupidly upgraded from Ubuntu 7.04 (Feisty) to 7.10 (Gusty). Now I can't hibernate or suspend my laptop, so I have to power it off each time I want to go somewhere else. My Beryl effects I love have gone and been replaced with something. Thunderbird seems to fall over when starting up and RSSOWL beta 6 has stopped working now. Can I fix all of these soon? Maybe not, does anyone know how to downgrade back to 7.04?
