There were only two small issues :
1. For some reasons, the ethernet module was not loaded. I had to load it by hand, but did not have to specify this in any conf (ie:
/etc/modules). Now the module autoloads perfectly.
sudo modprobe sky2
2. The sound was working but once I unppluged the speakers, I notice that the internal speakers weren’t working. I had to edit
/etc/modprobe.d/alsa-base.conf (as root) and replaced this line :
options snd-hda-intel power_save=10 power_save_controller=N
options snd-hda-intel model=hp-dv5 enable_msi=1
Now, everything seems to work fine (keep fingers crossed).
