As a newer Ubuntu user switching from Windows a few months ago (and couldn't be happier), I have to seek help with the proprietary Nvidia drivers.
I've only been able to get the nvidia-331-updates drivers (or earlier) to work correctly with my system, but the 340 or 346 (most current I believe?) from xorg-edgers ppa leave me with either a black screen or a total freeze on the splash screen at bootup.
I am on a laptop with an Intel i7/Nvidia Geforce GTX 860M setup, so I have a feeling Optimus technology is party to blame for my problems, although I currently have everything running correctly with Bumblebee ONLY while the 331-updates or older drivers are installed.
I realize that there are many forum posts that address this or similar issues, and believe me I have read ta lot of them, but either they haven't solved my problem or my technical expertise in the Linux environment is still lacking.
From a few things I read, this may be a problem caused by a kernel update and how it relates to the drivers from this repository? Should I just deal with it and wait for updates? Any help would be greatly appreciated.
