Most of the issues in this thread seem to be users who have: Changed the way the X server works (sliderotate) Installed a new kernel or initfs Are booting from SD card Have installed powermenu ... These things change the way the tablet works. Nokia aren't going to be able to test and support these things. It's up to the people who package these add-ons to find a way of safely reverting back to the previous behaviour if they find the world they're inhabiting gone wrong. Or to disable auto-update. Or to better inform their users.
