After fighting Nvidia optimus too long, I've decided to give up and try to just get 3d working, using any way. I've tried out Fedora 15, which actually worked for my computer -- nice 3d graphics, recognised my intel card and used the driver. I'm trying to install the intel graphics on a 11.04 alienware M11x. First step I figured would be disabling nvidia, but using sudo echo "blacklist nouveau" > /etc/modprobe.d/blacklist-nvidia.conf says permission is denied (Yes, I definitely used sudo). Any suggestions how to do this?
System: Alienware M11x R3
[8gb ram, Intel Core i5-2537M 1.4GHz (2.3GHz Turbo Mode, 3MB Cache), NVIDIA GeForce GT540 graphics with 1.0GB Video Memory and Optimus]
You cannot disable the Nvidia card by default, it's hardwired to the Intel CPU. You had 3D issues because the card could not be used, but the drivers were still loaded, preventing the Mesa OpenGL module from being loaded. This breaks graphical effects, 3D capabilities and such. Uninstalling the nvidia driver reverts this behavior.
Your sudo echo command failed because of Redirect the output using `sudo`
Optimus is not supported by nVidia for Linux. For a longer explanation and possible workarounds, see Is a NVIDIA GeForce with Optimus Technology supported by Ubuntu?
