при установке дров nvidia вот такой касяк You appear to be compiling the NVIDIA kernel module with a compiler different from the one that was used to compile the running kernel. This may be perfectly fine, but there are cases where this can lead to unexpected behaviour and system crashes.

If you know what you are doing and want to override this check, you can do so by setting IGNORE_CC_MISMATCH.

In any other case, set the CC environment variable to the name of the compiler that was used to compile the kernel.

*** Failed cc sanity check. Bailing out! *** make: *** [gcc-check] Ошибка 1
