Annoying Graphics issue

[joliv999]

Hi,

I recently upgraded to the latest Sierra and while everything was mostly painless, I keep on having a minor issue.

I have the latest Nvidia drivers installed, select those to be used in "System Preferences", but whenever I restart, it goes back to default OS X drivers.

While everything still seems to work fine, no hiccups or crashes, the annoying part is that every time I switch on my computer, I always get a black screen after clover boot. I press the re-set button and after the 2nd boot, everything launches fine.

In a nutshell, everything works, the only thing is that whenever I restart my computer, after the initial boot, it needs a re-boot to launch properly. EVERYTIME!!! Weird.

I've been through many related posts, tried many of the different suggestions that were provided, nothing worked.

Below my config.plist

Hope someone can give me a hint. It's probably something minor, but I don't see it. Thanks in advance.

System parameter NvidiaWeb is missing.

New Method for Enabling NVIDIA Web Drivers in Clover

Thank you for your reply. Actually tried this before with the key for "NvidiaWeb" in the config.plist. Had to remove it because it would always give me a black screen even after several restarts and reboots. Strange...

Tried almost everything... installed NvidiaWeb, un-installed again, all kinds of config.plist settings, always comes back to the same. I'm sure that this is some graphics issue or setting, but can't figure it out.

It's a little bit frustrating and annoying, having to re-boot once after each and every restart...but apart from that everything works like a charm. Perhaps I should just try to be happy with what I have...could be worse.

This is caused when your board does not have native NVRAM support.
