i'm using an N810 often. But I miss some applications on it. So I try to install mojo from handhelds.org. But I don't know how and couldn't find a step by step. Installing in qemu I found, but on the real hardware nothing.
Or how can I set up the wlan after intalling deblet-sid-gnome?
You could get involved in our new Mer - maemo reconstructed progect, it is supose to be the successor of Deblet and will be based on mojo's ubuntu port. It will also possibly use xserver-xorg and also use some stuff from maemo and deblet. we are still in our pre-build stage, but there are instructions on how to bootstrap and set up a basic bootable ubuntu system.
Further information regarding Mer and the basic instructions for bootable ubuntu can be found here. If your intrested in getting involved, pm Stskeeps and he will get you started.
