The koala hates me

All kubuntu releases since 8.10 don't like my laptop (hp 2710p), seems that kdm doesn't behave well with my graphic card. I never had all this problem with my previous laptop, but that had a NVidia graphic card, while this one have an intel graphic card (this shows that open source drivers doesn't automatically means better drivers).

Anyway this is a serious issue for me, cause linux is my only os on my laptop and my actual kubuntu is reaching it's end of life. Let's hope to have an happy ending.
