Can't use nvidia card/driver on optimus notebook
- by Mr. Pixel
I installed (once again) the latest official nvidia driver for my GT540m on Ubuntu 11.10.
Even though everything seems OK with my xorg.conf file (I've manually added BusID "PCI:1:0:0", since lspci shows 01:00.0 for my GPU).
The problem is, when I use the xorg.conf file generated by Xorg -configure, Xorg automatically loads the Intel GPU.
So I removed everything that was not related to my nvidia card, basically leaving my xorg.conf with one screen and one device (with the nvidia driver and the above-mentioned BusID), and Xorg fails to start.
The log says something like "Devices on GT540m [newline] none"
And a few lines later, something like "NVIDIA(0) found a screen, but have no device for it".
When I don't set the BusID, it doesn't seem to detect my card either.
Thank you for any suggestion.
PS: If possible, I'd like to avoid bumblebee or any similar "hybrid graphics" solution, last time I tried I ended up reinstalling Ubuntu.
Edit: Allow me to clarify the problem.
I have a notebook with a GT540m graphics card, and an integrated intel gpu.
I want to use the graphics card with full hardware acceleration and its official driver, as I do under windows.
