I'm currently stuck at a problem that I can't solve by myself. Recently, my OBS (Open Broadcast Software) stopped working, so I've decided to test a little bit around to get it fixed.

I've done update, upgrade, dist-upgrade and -f install and did several updates, including linux header updates which seem now to make problems.

After a reboot I've only had 1 single desktop for use, and the max resolution was 800x600. Also, my nvidia X Server-Window hasn't any more the settings that were available before (only 2 options now, both useless).

I've purged all nvidia-packets an reinstalled nvidia-304 and nvidia-352 (I wasn't sure which one I need, since I have a GTX 780 - or 740, not sure right now). Both didn't worked.

So basically, in short, here's my problem:

  • having a GTX 7xx Graphic Card
  • Using Ubuntu 14.04
  • recently updated linux headers trough apt-get dist-upgrade
  • now having bugs with the graphic engine.

How can I fix this, and how can I get appropriate Drivers back to working?

Thank you very much.

First remove all currently installed NVIDIA software.
Select the Ubuntu menu entry and press the E key.
Add nouveau.modeset=0 at the end of the linux line.
Press the F10 key to boot into the Ubuntu system.

When the login screen appears press Ctrl+Alt+F1.
Enter your user name and password and then execute :

sudo apt-get purge nvidia*  
sudo reboot

Install the latest stable drivers for GTX 7 series cards.
Select the Ubuntu menu entry and press the E key.
Add nouveau.modeset=0 at the end of the linux line.
Press the F10 key to boot into the Ubuntu system.

When the login screen appears press Ctrl+Alt+F1.
Enter your user name and password and then execute :

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install nvidia-367
sudo reboot

Note : Set a Space between the last character in the linux line and nouveau.modeset=0.
After the NVIDIA drivers are installed adding the boot parameter is not necessary anymore.
When you want to install the latest official drivers, replace nvidia-367 with nvidia-370.

  • It keeps telling me that nouveau.modeset cannot be found. What did I do wrong here? I eventually blocked nouveau in the blacklist before. Not really sure if I undid this change.. – Max Oct 30 '16 at 15:47
  • This site is telling me that specific nvidia-versions are needed for specific graphic cards: https://wiki.ubuntuusers.de/Grafikkarten/nvidia/nvidia/ – Max Oct 30 '16 at 15:51
  • @Max : Undo the settings you made before and follow exactly the description ... this method worked in most of all cases ... and the article you mentioned somehow is a bit misleading, it tells you which drivers are available in the default repositories. In case that you still receive an error - try it without adding the boot parameter. Most important is to perform the complete drivers installation from the virtual console. – cl-netbox Oct 30 '16 at 16:05
  • Okay, thanks. In dpkg I still have a lot of nvidia bundles, all with . Shall I worry about those? – Max Oct 30 '16 at 16:10
  • @Max : After completely purging the old NVIDIA drivers / software and rebooting to perform the new drivers installation, everything should be correct ... now please try it out and report back the results. :) – cl-netbox Oct 30 '16 at 16:12
  • Your solution hasn't worked. :/ Im still having the problems. Did it tree times to be sure I did nothing wrong (install, reboot, uninstall, reboot, install reboot, ...). In additional drivers I have NVIDIA binary driver - version 370.28 of nvidia-370 get used (open source) and a lot of different other versions. – Max Oct 30 '16 at 16:23
  • @Max : Then something else must have gone completely wrong, maybe a broken kernel installation ? – cl-netbox Oct 30 '16 at 16:28
  • I updated to 16.04 and trashed the old installation. Nvidia seems to have huge bugs with newer linux headers, or vice versa. Just for your information. – Max Oct 31 '16 at 12:14
  • @Max : Thanks for your feedback ! Well you know, I am using ubuntu since 2007 on different machines, two of them with NVIDIA graphics. Right now I am on 16.10 with kernel 4.8 - I ran 16.04 with kernel 4.4 for six months and never experienced any problem. All depends on a proper setup : I always perform clean installations and never upgrade a system. The first thing I do after the basic system installation is to install the latest stable NVIDIA drivers. Maybe that makes the difference - I wish you good luck to getting your issues sorted out. You may want to consider starting over from scratch ? – cl-netbox Oct 31 '16 at 13:36
  • I've started new from scratch when I've installed Ubuntu 16.04 over my now old Ubuntu 14.04. I didn't installed any nvidia drivers, and switched from nouveau to closed-source, tested 361 drivers, rebooted -> Error. Am not really sure what I'm doing wrong here. – Max Oct 31 '16 at 14:19
  • @Max : Eventually it is possible that you are facing a graphics adapter hardware failure, otherwise I have no explanation for what's going on here. One last idea : Please reinstall 16.04 once again, but before you start, format the target partition with ext4 file system to clean everything that was installed. You can use GParted for this - it is included in the installation media. When the basic installation is finished, boot the system and install the NVIDIA drivers from a virtual terminal and reboot afterwards. Hope that works ! :) – cl-netbox Oct 31 '16 at 15:48
  • Would you mind posting that solution stepwise to http://askubuntu.com/questions/843866/ubuntu-16-04-switching-from-nouveau-to-closed-source-driver-after-luks-auth-p? That would help others in the future! :) – Max Oct 31 '16 at 15:59
  • @Max : When it really does work, of course I can post this as an answer to your other question, but first you have to try it out - otherwise it wouldn't make much sense. Here you can find comprehensive information on How to prepare a disk ... including a presentation -> Prepare the disk for the installation .... – cl-netbox Oct 31 '16 at 16:09
  • Thank you so much for your help! Really appreciated, as a beginner, this is the best help I can ask for. :) – Max Oct 31 '16 at 16:15
  • @Max : You're welcome ! Let's hope that it's not a hardware issue and we can get it done. Prepare the disk and install ubuntu as shown in the slides, then install the drivers ... once finished, please report back ... :) – cl-netbox Oct 31 '16 at 16:22
  • I just solved it. Installing graphic-drivers-ppa and stick to nvidia-370 solved my problem. What could I ask for more, right now? :) – Max Oct 31 '16 at 16:22
  • Sure thing. I now need t omove over the recovery header in order to get it loading, but thats fine for me to be honest... :') – Max Oct 31 '16 at 16:29
