Re: GeForce 6600 / Dual Screen / Ubuntu
In your bug report, I see:
(EE) NVIDIA(0): The NVIDIA kernel module does not appear to be receiving
(EE) NVIDIA(0): interrupts generated by the NVIDIA graphics device.
(EE) NVIDIA(0): Please see the FREQUENTLY ASKED QUESTIONS section in the
(EE) NVIDIA(0): README for additional information.
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device!
(EE) NVIDIA(0): *** Aborting ***
I'd suggest you take a look at the README for further guidance. If upgrading the kernel is what triggered this problem, then you likely are hitting a kernel bug.
