[kernel 3.13 rc1] could not find /var/lib/dkms/nvidia-331/331.20/build/.nv-kernel.o.cmd for /var/lib/dkms/nvidia-331/331.20/build/nv-kernel.o

[dino99]

Installing the newest 3.13 kernel (from Canonical kernel team) on Trusty i386 seems to build well with nvidia-331 driver at first glance.
But then X fails to start. It has been reported here: https://devtalk.nvidia.com/default/topic/644906/linux/331-20-on-3-13-rc1-kernel/
and a workaround is also proposed:
/var/lib/dkms/nvidia-331/331.20/source$ sudo gedit nv-acpi.c (comment out line 303 -> 311).

Looking at the make.log, we can see the main errors logged at the beginning of the file, then at the end:

NVIDIA: calling KBUILD...

Status changed to 'Confirmed' because the bug affects multiple users.

New test feedback:

as the nvidia driver was not usable previously, i was using 'nouveau' .
So i've tried to use nvidia again after the latest upgrades from 'main' archive:
- there has been some transitioning hardtime, witch have needed to use 'recovery' mode and also reboot
- but now with kernel 3.13.0.8 and nvidia 331-38, X is working as expected (at last, seen a lot of users complaints also across forums)

That said, i cant tell if the reported issue still need to be investigated, or simply marked this bug as 'fixed'

This is now fixed in 14.04
