Install Nvidia driver from repo instead of .run.
No need to install build packages.
Coolbits 1 and 2 are unnecessary.
1 (bit 0) - Enables overclocking of older (pre-Fermi) cores on the Clock Frequencies page in nvidia-settings.
2 (bit 1) - When this bit is set, the driver will "attempt to initialize SLI when using GPUs with different amounts of video memory".
systemctl disable lightdm
or
systemctl set-default multi-user.target
to prevent lightdm from auto starting.
All major distros have adopted systemd for process management and logging so take advantage of that instead of using antiquated rc.local, screen, cron, &, >, etc.
