This appears to be a fairly common issue but the solutions I tried have not worked. Using nvidia-340.106

Solutions I tried:

  1. compizconfig-settings-manager Force full screen redraws (buffer swap) on repaint

  2. Updating /etc/X11/xorg.conf to add (Option "FlatPanelProperties" "Dithering=Disabled")

  3. Enable triple buffering in xorg.conf

  4. Using nvidia-settings to enable Sync to Vblank, Allow Flipping, Use Conformant Texture Clamping

  5. Use KDE and GNOME

  • You can use nvidia-smi to see if nvidia is running gnome-shell on 17.04+ – Jonathan Jun 4 '18 at 23:51

I had the same issue and this is what worked for me I started following this article How to install the NVIDIA drivers on Ubuntu 18.04 Bionic Beaver Linux

In a nutshell I listed the recommended drivers using

$ ubuntu-drivers devices

then to install the recommended drivers

$ sudo ubuntu-drivers autoinstall

or you can use apt to install whicheve driver you prefer if it is not the recommended one

$ sudo apt install nvidia-390

once I rebooted my system I was good to go but if you still have problems a few other things are mentioned in the article one being disabling Noveau Nvidia driver How to disable Nouveau nvidia driver on Ubuntu 18.04 Bionic Beaver Linux To summarize you blacklist the Nvidia nouveau driver:

$ sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
$ sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"

and then you can confirm the content of the new modprobe config file:

$ cat /etc/modprobe.d/blacklist-nvidia-nouveau.conf

you should see something like

blacklist nouveau
options nouveau modeset=0

    That didn't work for me, still the same flickering. – chaNcharge Jun 11 '18 at 23:19
  • That didn't work for me either – debugging XD Jun 28 '18 at 5:19

    This worked for me. – Gaurav Gandhi Nov 29 '18 at 14:51

Basically among other things simply, read Post 5 for the none specific version.

Run this

sudo gedit /etc/modprobe.d/nvidia-drm-nomodeset.conf

Add this line

options nvidia-drm modeset=1

  • Instead of sudo gedit use sudo -H gedit which is safer. – WinEunuuchs2Unix Jun 23 '18 at 21:01
  • That doesn't seem to work for me either, so I've stuck to using the nouveau drivers. Is there a step I'm missing? – chaNcharge Sep 16 '18 at 6:37
  • Had this issue with nvidia 410. Upgrade to 415 Followed steps to blacklist nouveau. Finally the options nvidia-drm modeset=1 solved. – Andrew Lavers Jan 10 at 3:37
  • This broke my desktop, had to log in with the shell and comment the line. – octohedron Aug 5 at 17:17
  • This worked for me on the ASUS N551JK laptop. (Nvidia optimus with 850M) – Andrew Aug 9 at 1:44
