I have had both Ubuntu and Mer working in the past on my N810. Currently, running a version of Mer on it with E17. I haven't tried the Ubuntu install in a few weeks though, so something may be broken since then. Anyway, if you really want to try it, and don't mind a little work, you can install Mer and then manually remove conflicting packages between Mer and Ubuntu and then install whatever part of ubuntu you want...It's not the quickest method, but it works.


If you still have Jaunty installed on your system, you should try to chroot into it and then remove the ubuntu-splash packages...The problem could be that your system is trying to use the wrong bootloader splash.
