Been having a problem with my Nvidia 640M not being recognized by Ubuntu after an update. Tried many things but couldn't find a solution yet. I'm relatively new to Ubuntu so I'm not sure where to look at.
I'd really appreciate help with this
Something I noticed on nvidia log:
echo >&2; echo >&2 " ERROR: Kernel configuration is invalid."; echo >&2 " include/generated/autoconf.h or include/config/auto.conf are missing.";\ echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; echo >&2 ; /bin/false)
