Switchable Graphics Trouble

[Ctrl]

I'm having the same troubles as conbrio, a black screen in place of anything 3d (the menus, crosshair, sound and stuff loaded) i have the same switchable graphics & gpu's (ATI Mob. Radeon HD 6770m and Mobile Intel HD). Initially, the amnesia application would crash upon launch, which i fixed after a few hours of trying to find the right driver, updating it from 8.830.6.1000 to 8.830.6.2000, which it is still at. I've downloaded a bunch of the stuff on this thread, nothing worked. I have an HP dv7 entertainment notebook 6143cl. i have the hp log attached, not sure how to put it in a spoiler.

Edit: Just installed the 1.2 patch, which doesnt run.(SDL.dll is missing, already reinstalled once.) Normal version is still the same. Not exactly sure what to do at this point, maybe i'll look for intel drivers. I'm surprised it doesn't load even on low graphics though, as it recognizes the intel GPU but that is the only one.
