For some weird reasons, by deleting all configuration files in my home directory, the behavior reverted to what it was with Ubuntu 13.10. I cannot reproduce the crash anymore. I still need to add the correct resolution with xrandr as it is not detected correctly. Somehow there is a lurking bug in i915, but this must have been triggered by some weird settings I had in Unity. This is my best guess.
