i got a dell inspiron N5110 with an intel integrated graphic chip, and an nvidia GeForce GT 525M card. there is no option in BIOS to disable on or the other.
I installed BT5 R3 64 bit.
None, but none of the solutions here and on some other forums worked for me. I tried like 10 guides, found in BT forums and on some other forums, but each time the startx fails, with the same error "no screen found", so i ended up reinstalling BT for like 10 times in the last 3 days. i tried with the generic nvidia drivers, with the latest drivers downloaded from nvidia, with both 64 and 32 bits. nada
After a clean re-installation the x server starts, but i get like 800x600 resolution.
Is there someone out there that have the same hardware, and that successfully made this thing work?

Thanks in advance for any idea that would work
