For The display is blank & The display flickers I faced the same issue but now every thing works fine. The main issue was with gdm, not the NVIDIA driver. Installing lightdm and setting it to the default desktop manager was what fixed this for me. sudo apt-get install lightdm choose lightdm as the default when prompted. I'm using the NVIDIA ...

Through Ubuntu 15.10, Ubuntu's handling of Secure Boot stopped at GRUB -- that is, Ubuntu's version of Shim would launch Ubuntu's version of GRUB, which would launch any Linux kernel, whether or not it was signed. This was a very low bar of support for Secure Boot. For comparison, Fedora's GRUB would launch only signed Linux kernels, and Fedora's kernels, ...

I was able to get 15.10 installed by doing this: Modify /etc/grub.d/10_linux so that any subsequent updates don't overwrite the grub.cfg file and thus your modifications. sudo -H gedit /etc/grub.d/10_linux Look for line 177. It should start with linux ${rel_dirname}/${basename}.efi.signed root=${linux_root_device_thisversion} After ro, ...

Thanks to the collective effort of the community, I have managed to get it working. First, get to a Terminal (by pressing ctrl-alt-f1 if you can't log in, or through recovery mode). Install nVidia drivers version 364 (package nvidia-364). sudo apt-get install nvidia-364 If the package is not found, add the ppa that contains it: sudo add-apt-repository ...

Usually the answer to this is by resetting dconf entries for unity: dconf reset -f /org/compiz/ setsid compiz This seems to be due to bug #1569357 on launchpad. Usually they also give a few remediations for the bug in the launchpad entry, and it only seems to happen with sddm (the simple desktop display manager) - it does not happen with lightdm. Using ...

I upgraded from Ubuntu GNOME 15.10 to 16.04 and was faced with a black screen. Using systemctl status and digging through logs, I found that the proprietary NVidia drivers were broken. Purging nvidia-* and reinstalling gdm got me to low-graphics mode, but reinstalling the NVidia drivers brought back the black screen. As it turns out, Secure Boot had been ...

I solved this problem. This problem was caused due to secure boot and EFI_SECURE_BOOT_SIG_ENFORCE in linux kernel 4.4.0-20 and later. I installed the nvidia-364 drivers and entered the key when asked. Then i rebooted the system. when blue screen of mok management appeared i pressed any key to changed it. Then it asked for password characters. then it let ...

I had the same problem since yesterday evening. I suspect it was caused by a recent kernel update. Check your kernel version: uname -r For me, the nvidia driver does not work with version 4.4.0-21, but it does with a older kernel from Ubuntu 16.04, 4.4.0-18. Here is how you can test this: If you have the nvidia drivers still installed, make sure dkms ...

It is very difficult to type in a constantly switching console, but not impossible. I found out that the constant switching was caused by gdm3, so I stopped stopped it: sudo /etc/init.d/gdm3 stop I could probably have done it by ssh-ing to my desktop as well, which would probably have spared me the difficulty of having to type in a constantly switching ...
