I think I'll have to register with the people who have a N800 that exhibits same symptoms :/ - as my faithful companion has become ill.

My N800 was bought may-june 2008 through Amazon, but through the US, so I'm not covered by warranty repairs, being in Europe and it seems like the LCD supplies have dried out and I don't have the cash for getting a new one currently.

Yesterday, I came to my office, where my N800 was charging through a AC-3E - which it had difficulties with earlier in the day. Previously, I had the issues of the dark spots on right side of screen as well. At that point my tablet was vertically scrolling on the charging menu. Later that evening, it continued doing the same.

I tried booting Mer, and the rotating happened as well in our splash screen, which is basically apply a fb image and apply a manual update of the framebuffer. And this means, contrary to my initial beliefs, that it is not a userland problem of Maemo (that is, X server isn't to blame) - so it is either the hardware or kernel issue.

It currently does not do this all the time (yet..) but it certainly limits the usability when it -does- happen.

You can see what happens on http://www.youtube.com/watch?v=hcm5TYGwTwU

For what it's worth, I should be able to continue developing Mer, as I have a N800 in my office, but without a properly working personal N800, it will be difficult to do proper N800 development in my free time - but I hope I can rely on the testers in the project to test things.

A plus is also the fact that we began with making Mer, it was with the goal to make Mer portable - and hence I still have the X86 version of Mer (which is pretty similar to the one running on tablet), so I can still work on the portable part of it, and try my best with the 770 if I need to test something..
