Fresh install of Ubuntu 22.04 with visual stuttering on both wayland and Xorg (disabled wayland on /etc/gdm3/custom.conf and rebooted). Here is a recording showing the stuttering on the gnome terminal, and here is a recording showing the stuttering when moving the gnome terminal window. Please note the spike in CPU usage on the latter example.

If I go to the "text mode" with ctrl + alt + f3, there is no stuttering. Also, on Ubuntu 21.10 I had no such issue.

I have a i7 9770k and RTX 2070.

What should I do?

  • Please confirm you have the recommended Nvidia drivers installed and running before anything else. – ChanganAuto Apr 25 '22 at 15:49
  • Sorry. It is installed: https://pasteboard.co/ScF0TczkpOa9.png – Frederico Schardong Apr 25 '22 at 15:53
  • Have you disabled Secure Boot in UEFI? You can do that unless dual-booting with Windows 11 in which case you need to use MOKutil to sign the Nvidia proprietary drivers. – ChanganAuto Apr 25 '22 at 15:57
  • `mokutil --sb-state` says `SecureBoot disabled`, even tough my UEFI has Secure Boot enabled. I am planning on using Windows 11, so I guess mokutil is the way to go. Is this something all nvidia owners have to do? – Frederico Schardong Apr 25 '22 at 16:18
  • @FredericoSchardong don't have answers for you, but I have the same stuttering. On Ubuntu 22.04 with I9-10885H and GTX1650. Did you manage to find any improvement? – Janne Mattila Jun 02 '22 at 12:30

    @JanneMattila no luck so far. I haven't tried the `mokutil` tool yet, though. I am back to Ubuntu 19.10 and waiting for an update from Canonical to fix this. – Frederico Schardong Jun 02 '22 at 13:03
  • @JanneMattila I gave Ubuntu 22.04 a try yesterday. After updating to the latest drivers, everything is much better now. It is not flawless, but pretty usable. – Frederico Schardong Jun 09 '22 at 12:13

    @FredericoSchardong that's nice! I improved my own UI experience by toggling "Force (Full) Composition Pipeline", which removed some screen tearing that I was experiencing: https://wiki.archlinux.org/title/NVIDIA/Troubleshooting#Avoid_screen_tearing – Janne Mattila Jun 09 '22 at 13:22

I had this issue Turned out it was the driver In terminal

ubuntu-drivers devices

This told me what model my GPU is and generated a list the top of that list is the preferred driver.
So I did an update and an upgrade then

sudo ubuntu-drivers autoinstall

then I installed the driver from the top of that list and rebooted

sudo apt install nvidia-driver-450

Had stuttering / choppy audio on mij Ubuntu 23.04. Took me a long time to discover a potential solution. I disabled the use of Waylan, rebooted and it seems to have disappeared.

My config Windows 10 with Virtualbox 7.0.8 as host. Client is Ubuntu 23.04. Everything completely patched and up-to-date. The post which brought the solution: How do I use X instead of wayland on 22.04?
