Ubuntu 16.04 nvidia drivers don't work

I also installed Ubuntu 16.04, clean install on a new hd and everything worked fine until I switched to NVIDIA driver. After rebooting I couldn't get past the login screen. The solution that worked for me was to disable secure boot.

While stuck in login loop, I switched to console Ctl+Alt+F1, rebooted and disabled secure boot in UEFI. Now everything works with nvidia driver installed.

I had this problem too. I just run this in a console (press Ctrl + Alt + F1, in login page to show first virtual tty):

sudo apt-get purge nvidia*

After this, rebooted and then i could login. After that, I installed intel drivers first, and then nvidia-361.

These were the steps I followed:

1. sudo apt-get purge nvidia*
2. reboot (now I had noveau display driver working)
3. sudo apt-get install intel-microcode
4. sudo apt-get install intel-gpu-tools
5. Reboot (for testing, everything was working fine)
6. sudo apt-get install nvidia-361 (I think nvidia-current is better long term option).
7. Reboot

Now I have these (sorry they are in spanish):

Additional drivers

I also have an issue with 16.04 and Nvidia 361.42 driver. You can use prime-select intel or Nouveau driver as temporary workaround. I have had endless issues with the official Nvidia Ubuntu drivers over the years, it's very hit and miss. I thought the introduction of Steam OS and the growing number of Linux users/gamers might encourage them to better support Linux :/

Found the solution (this time for real),
i decided to be an ubuntu expert , so i went to google and typed :

debug ubuntu

then it gave me the page Debug and i selected unity .
in some part i needed to do :

$ unity --advanced-debug

(gdb) set logging file unity.log
(gdb) set logging on
(gdb) b _exit
Function "_exit" not defined.
Make breakpoint pending on future shared library load? (y or [n])
[Answer yes (y)]

(gdb) run

[ and when compiz/unity crash, do...]

(gdb) bt full

[ then CTRL-D or re-run compiz to continue working ]

(gdb) run

after running this i noticed the error :
compiz (core) - Error: Plugin 'opengl' not loaded.

i searched for this error on google and it gave me this thread Unity missing? Can't see top or side panels , the answer here works .

I think I have found the solution. I have had terrible trouble with installing 16.04 on my main machine. Nvidia drivers crash and you can't log in and you have to resort to sudo apt-get purge nvidia-*. Chrome was crashing.

I have had no trouble with my secondary machine which has a traditional bios. It is only my main machine with UEFI firmware. The most frustrating thing is that I had been running 16.04 from a daily build for some months and it was rock solid.

I have noticed that the installer asks for a password if you download drivers as you install. The solution is to TURN OFF SECURE BOOT. Installing Ubuntu (from the UEFI option in the Bios Menu) then proceeds faultlessly and the system seems stable. 16.04 is not perfect e.g. to install Chrome you have to use gdebi, but at least it is now useable.

For me the solution after lots of searching was to disable UEFI in the BIOS. My machine runs only Linux so disabling UEFI was not a big deal.

I was having problems with VirtualBox and NVIDIA and could not get either to work with Ubuntu 16. I was seaching for "ubuntu 16 UEFI Virtual Box Fail kernel build" and came across a link regarding Virtualbox that made me wonder about UEFI and disabling it.

After disabling UEFI I reinstalled Ubuntu 16. During the install the dialog box that had the "Secure boot" entry was devoid of that content.

I'm happy to report that Ubuntu 16 is running and I'm having no problems with either NVIDIA or VirtualBox! Both are working as expected.

Thanks to those that shared their knowledge so I could move forward.

Ubuntu 16.04 comes with xserver Xorg 1.18 and the configuration is a little bit different than previously. In a dual GPU setup, from Arch Linux wiki, the /etc/X11/xorg.conf should be like this:

Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "nvidia"
    Driver "nvidia"
    BusID "PCI:1:0:0"
    Option "AllowEmptyInitialConfiguration"
EndSection

Replace PCI:1:0:0 for your nvidia Bus ID. You can check it with:

$ lspci | grep -E "VGA|3D"

It works for my HP laptop with dual GPU: Intel (Skylake) and NVIDIA 940m. Remember it's possible to switch between them with prime-select command (as root) or nvidia-settings official application and reboot your computer.

I had a similar problem, but my issue in particular was caused by the ESET NOD32 Antivirus.

The driver installation, both from the ubuntu repos and the manual NVIDIA driver installation was getting stuck building the DKMS modules.

I found instructions on how to uninstall ESET and after uninstalling, I set my run-level to 3:

sudo systemctl enable multi-user.target
sudo systemctl set-default multi-user.target

Blacklist nouveau:

Edit /etc/modprobe.d/blacklist.conf as super user and add:

blacklist nouveau

Then purge NVIDIA and reboot:

sudo apt purge nvidia*
sudo reboot

Once in run level 3, I manually installed the latest NVIDIA driver, set the run level back to 5 and rebooted.

sudo sh ./NVIDIA...
sudo systemctl enable graphical.target
sudo systemctl set-default graphical.target
reboot

Things were finally working, so I re-installed the Antivirus. Will have to wait for a kernel update to ensure that the NVIDIA driver gets rebuilt then.
