NVIDIA have released another new driver – 390.48, and details are here: http://www.nvidia.com/Download/driverResults.aspx/132530/en-us

Surprisingly, this version is still not able to function with Kernel 4.16 (tested with 4.16-rc7):

I am still using the patched version of 384.111 (see http://rglinuxtech.com/?p=2227 ), and I should mention that this also works OK with Kernel 4.15..

Barring unforeseen issues, Kernel 4.16 ‘Final’ should be released in 4 days time from now…
