Update started no request and went without flaws.
With 7.10 installed, the compiz desktop effects worked out of the box (until an update to xorg 7.2-5ubuntu3. Since then the nice desktop effects are gone again (Launchpad 144077)
All in all the machine is stable. I update regularly and things work pretty stable.
Some known issues:
- Thunderbird does NOT honor gnome-vfs. They say it should but it does not (Launchpad 105088)
- Having usplash enabled (kernel parameter splash) the machine hangs after a resume from suspend to RAM (Launchpad 106198, 146489)
- After resume from suspend, sound does not work (Launchpad 146491)
