It looks like your system is currently running switchable graphics; this means that your computer runs Intel graphics and Nvidia or ATI graphics at same time. This type of computers do not use generic Intel drivers, they require special drivers from the computer manufacturer. I recommend contacting your computer manufacturer for further assistance.
I just (today) got my laptop back from HP, (yes they had it that long and did not resolve it)
Going through the registry, I am seeing a hole I cannot fill for screen rotation
There is no key for it...
Example, igfxcfg.exe would be in some other locations.
Not saying Intel did this, but if I could point it as an HP problem not intel, it would help me out tremendously.
If it is intel, I could use the proper files for creating this. I am willing to do it on my own at this point, as HP has been less than helpful. They had my laptop 46 days. I have only had it 18 of the 64 days of ownership.
