Linux on the ARM Chromebook: Not quite yet
Installing ubuntu on the Chromebook was really simple, and the result works in principle, but it's not usable. Too many missing packages, some random crashes (while using Unity), and the Chromebook doesn't sleep properly.
KDE (kubuntu-desktop) seems to work better than Unity/Gnome, but not well enough for production use, not even by a twenty-year linux veteran such as myself. I don't want to spend much time hacking on it now, so I'll try again in a few months.
