Created attachment 174361 [details] Kernel configuration file. This change happened from 4.0.0-rc6+ to 4.0.0+. Someone decide to make this symbol GPL only and blocked the compilation of NVidia proprietary drivers to the whole world. Here's the complete compilation error for which there's no workaround. -------------------------------------------------------------------------------- nvidia-installer log file '/var/log/nvidia-installer.log' creation time: Sat Apr 18 00:07:01 2015 installer version: 346.59 PATH: /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/opt/bin:/usr/src/unrealengine/Engine/Binaries/Linux:/usr/x86_64-pc-linux-gnu/gcc-bin/4.9.2:/opt/nvidia-cg-toolkit/bin nvidia-installer command line: ./nvidia-installer Using: nvidia-installer ncurses user interface -> Detected 8 CPUs online; setting concurrency level to 8. -> License accepted. -> Installing NVIDIA driver version 346.59. -> Performing CC sanity check with CC="/usr/bin/cc". -> Kernel source path: '/lib/modules/4.0.0+/source' -> Kernel output path: '/lib/modules/4.0.0+/build' -> Performing rivafb check. -> Performing nvidiafb check. -> Performing Xen check. -> Performing PREEMPT_RT check. -> Cleaning kernel module build directory. executing: 'cd ./kernel; /usr/bin/make clean'... -> Building NVIDIA kernel module: executing: 'cd ./kernel; /usr/bin/make module SYSSRC=/lib/modules/4.0.0+/source SYSOUT=/lib/modules/4.0.0+/build -j8 NV_BUILD_MODULE_INSTANCES='...
