# Problem installing Nvidia drivers on 840m (12.04)

Just got an MSI GP70 2PE Laptop. The laptop has an Nvidia 840m and I need to utilize the GPU for my work. I've tried following the instructions (posted here: http://ubuntuhandbook.org/index.php/2014/06/nvidia-driver-337-25), but when I get to the login screen there is a crash report prompt and I am unable to do anything else (I can CTRL+ALT+F1 and get a working terminal, but that's it). I've also tried skipping over the install of nvidia331-updates-dev and just using the .run file downloaded from Nvidia, but that causes the same issue. Any ideas on what could be happening?

Note that a fresh install of Ubuntu works fine. However, when I do boot into that, just before the login screen appears I see a two line message starting something about 'nouveau unknown chipset'.

Also, under the Addition Drivers dialog it simply states "No proprietary drivers in use".

Here is a copy of my Xorg.0.log: http://textuploader.com/okaq

• Welcome to AU! I find those instructions a bit shoddy. Did you try to install the Nvidia driver through jockey (dubbed “Additional drivers”)? Can you include the content of /var/log/Xorg.0.log in your question please? – David Foerster Oct 1 '14 at 0:51
• Sorry for the mess of a message above. Just to clarify, when I open Additional Drivers there are no drivers listed to choose from, simply a line saying "No proprietary drivers are in use on this system". – Rob_S Oct 1 '14 at 11:48
• So besides the Nvidia GPU you have integrated graphics from Intel. Unfortunately I don't know how to deal with dual graphics adapters. What I can however see, is that there's no kernel module for the Nvidia driver. Can you provide the output of LC_MESSAGES=C dpkg --list nvidia-\* please? It should tell us more about what driver packages are installed. – David Foerster Oct 1 '14 at 13:44
