Brief status: Running lxdm and lxde on top of 12.04 with nemo kernel, it's stable enough, haven't seen oopses for days now. Installed only kernel and n900-configs package (fixes keymap, finally) from nemo. Feel free to experiment with other RPMs. If you don't see any images (like png, jpg, etc.), try Code: sudo apt-get install --reinstall libgdk-pixbuf2.0-0
sudo apt-get install --reinstall libgdk-pixbuf2.0-0
