I have a single SSD I dual-boot with Windows 7 / Ubuntu 11.10. I switch this drive daily between two computers. One is a laptop with integrated Intel graphics. The other is a desktop with an NVIDIA video card.
I want the correct driver to be used and 3D acceleration to be enabled automatically when I boot into Ubuntu on either computer. How do I achieve this?
When I boot Ubuntu with my laptop most drivers start up normally, but GM965 video driver doesn't load, therefore 3D acceleration remains off. The logs show the NVIDIA driver issuing an error about unavailability (looks like it's forcing the NVIDIA driver).
Is normal that Ubuntu 11.10 & Xorg nowadays don't have the same behavior as Windows 7? When I boot Windows 7 the right driver is loaded by PCI identification, and resolution settings are loaded via DDC from the monitor. I think Xorg can do the same thing like when you boot a live CD.
In order to diagnose I need to know how to configure video driver on modern Xorg deployments that deprecates /etc/X11/xorg.conf
Does anyone have any ideas to help me?
Thanks in advance
