Nvidia GeForce GT840M driver issues

[zan-public]

Hi, I have a brand new HP Envy 17t with a 2GB NVIDIA GeForce GT840M Graphics card.
Here's the rub, I can't get the nvidia driver to take over. I have installed the nvidia-340 driver from both the ppa: xorg-edgers/ppa and ppa:mamarley/nvidia (separately, purging out the driver and ppa between attempts) but still I get no glory. If I run:

nvidia-settings

I get:

(nvidia-settings:3858): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:121:0: Expected a valid selector** Message: PRIME: No offloading required. Abort
** Message: PRIME: is it supported? no


ERROR: nvidia-settings could not find the registry key file. This file should
       have been installed along with this driver at
       /usr/share/nvidia/nvidia-application-profiles-key-documentation. The
       application profiles will continue to work, but values cannot be
       preopulated or validated, and will not be listed in the help text.
       Please see the README for possible values and descriptions.

I have searched this and the only advice I can find is to install one of those two PPAs, update apt, then install the package... yea, no.
Also, I looked up my card on the nvidia site and they are specifying the 346 driver for it...

I am lost, confused, and quite frustrated. Can anyone explain what I am doing wrong?

Thank you.

Also, I did have this working for a couple of days, but then lightdm failed and wouldn't load, so I uninstalled lightdm, and switched to gdm, and thought all was well, then I noticed I lost the use of my nvidia higher functions... Can't seem to figure out what is going on.

I have a laptop with same graphics(intel hd + nvidia 840m), some time ago i managed to install 343.xx drivers, but my problem was that nvidia didnt have any vsync, plus 3d stuff was broken, so it was useless. Now, when i tried to install 346.35 newest drivers, ubuntu doesnt even boot, it gets stuck at black screen - its a general linux problem right now, xorg server is broken, linux kernel some new versions are broken (tty doesnt work), plus some other stuff, so i will just leave linux for like another year, its a minimum amount of time required for linux to get at least some things to get moving. I would suggest to do the same, because right now one problem leads to another, and there is no solution, if you are lucky to get everything to work out of the box, then its ok, but if not, then there is nothing you can do.

@startas;; Not, not and not.

If the manufactures do not provide code, then it is very demanding and difficult to reverse engineer the interfacing software. Recently Nvidia has provided assistance,

Install the required proprietary driver and then install 'nvidia-prime' to control the graphics sets.

if you have the will

you can make a way

hi, combination NVIDIA 346.35 and kernel 3.17.7 is ok for me, with all newer kernels i have the same problem like you.
i still didn't try kernel 3.19-rc6, but here's some good news: "Kernel 3.19-rc6 – Good News for NVIDIA"

Bashing-om,

I do have both of these installed and I still cannot get the nvidia driver to take over. Any thoughts?

zan-public; Well ...

Let's see if you DO have the driver loaded .

sudo lshw -C display

the configuration line in that output will list the driver installed ( if any) .
and while we are at it, see what the hardware is:

lspci -nnk | grep -iA3 vga

back to the basics

look and see

Update: A driver update for nvidia-340 came down the pipe on ppa:mamarley/nvidia today. This had no effect on the problem (Problem persists). Should I download the driver from nvidia, and install that? I really don't want to use non managed drivers...

[zan-public]

Yea, No change.

[Bashing-om]

zan-public; Yuk .

I am stuck, I do not know what else to advise, presently.

I Hate when that happens
