My 2.6.36-rc8 .config-uration and miscellaneous info
I haven't been running NVIDIA GPU on this computer for almost a year, but I do
remember that this option wasn't necessary last time I ran this video
accelerator.
Without this option my GPU doesn't get assigned any interrupts and I'm met with
this message upon trying to run X server:
(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): PCI:5:0:0. Please see Chapter 8: Common Problems in the
(EE) NVIDIA(0): README for additional information.
(EE) NVIDIA(0): Failed to initialize the NVIDIA graphics device!
/proc/interrupts inspection reveals that indeed NVIDIA is not listed there.
