Unable to boot Doudou (nor liveCD) with nvidia 8400gs CGNX-842LCI


I have a quadboot PC,
Windows 7 installs + works fine, Android-x86 same, Edubuntu same (unity works np), but Doudoulinux crashes the system (ctrlaltbkspace does nothing).
I installed Doudou via virtualbox initially (as all others except w7), but it just gave me “No signal detected” which is why i tried the liveCD, which also failed.
I get a black screen where the lower half is filled with vertical purple bars.
Using the same HD in another pc, edu/andr/doudou all work fine.

Ill keep this post updated if i find a fix. (gonna start with disabling xorg on boot, because it completely freezes the whole system)
