Hey there Daniel, thanks for helping out! I can confirm that what nuked my 23.04 install is bug 2023946, which I responded to a few days ago. While trying to fix the issue at hand, before I read your suggestion on how to potentially fix it, I followed a howto online, which was more or less suggesting the same thing that you asked me to try. Something went wrong while trying the potential fix and I was left with blinking cursor upon reboot again. I gave up at this point, saved my data and reverted back to 22.04.2 LTS for the machine in question. It took me an entire day to troubleshoot 23.04 and revert back to 22.04, but now everything is stable again. What I also noticed is how trying to install the proprietary Nvidia drivers during the initial install of 23.04 was causing issues, not so on 22.04.2 LTS, the latter which didn't install the proprietary Nvidia drivers at all during a fresh installation of the OS (even though the box for this was enabled / activated). I had to manually select the newest proprietary Nvidia driver for 22.04.2 after the OS was fully installed (using the preinstalled drivers tool app), and it worked like a charm. 22.04.2 is running well, no issues when resizing windows or any of the other things noticed in 23.04. The only thing that I notice on 22.04.2 LTS is that the framerate is a bit low when opening the Gnome overview initially (feels like 20-30 fps), but it gets super smooth at 60 fps when opening the overview for a second time right after the first attempt. In other words, it takes Ubuntu some time to catch up and make it smooth again, but when it does it's actually really smooth.
That said, I have a secondary machine here with 23.04 and an Nvidia gpu with proprietary drivers installed. I will be testing the suggestions that you wrote on 2023-06-16 later tonight, if I am able to bypass the issue in bug report 2023946 for the secondary machine. Will report back by tomorrow night with my findings - - - WIP. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2023776 Title: Ubuntu 23.04 + Gnome + Nvidia 525 + Vsync = low fps in Xorg sessions Status in mutter package in Ubuntu: Incomplete Bug description: Currently using Nvidia driver 525, which is the "tested" and recommended driver according to Ubuntu's additional driver tool (as of this writing). - manually resizing "files" windows = low fps and a little bit of pixelation - moving windows around = drop in fps every now and then - opening the Gnome overview = sometimes buttery smooth 60fps but sometimes stuttery low fps that takes time to "catch up" to smoothness again - resizing Chromium or Firefox window = low fps, glitchy window behaviour etc. How to fix it? Well, this is what I found works thus far: - disable both "vsync" and "allow flipping" in Nvidia-settings - now everything is buttery smooth again; all animations, apps, games and more - doing this will introduce lots of tearing on the Gnome desktop and applications though - then force full composition pipeline to get rid of the tearing by adding this start-up line to Ubuntu's start-up applications: nvidia- settings --assign CurrentMetaMode="nvidia-auto-select +0+0 {ForceFullCompositionPipeline=On}" - Use Wayland alternatively: Wayland doesn't have any of these issues at all, it's a buttery smooth fully vsynced experience ootb, but a bunch of new problems arise instead: Can't set global hotkeys for recording in OBS, OBS recording performance is pretty bad, Gnome folder windows start flickering somestimes, Gnome windows glitch out when trying to resize them manually, Steam flickering sometimes, browsers such as Firefox and Chromium have to be set to Wayland mode in order to solve stuttering video playback issues, Nvidia-settings is missing a bunch of settings and features when compared to X11... and more Hard- and Software: - Ubuntu 23.04 - Nvidia driver version 525 (tested) from Ubuntu's additional drivers tool - Core i7 7700 - 32 GB DDR4 RAM - Lenovo Nvidia RTX A2000 workstation GPU - TWO fullHD monitors connected via display port ProblemType: Bug DistroRelease: Ubuntu 23.04 Package: gnome-shell 44.1-0ubuntu1 ProcVersionSignature: Ubuntu 6.2.0-20.20-generic 6.2.6 Uname: Linux 6.2.0-20-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.26.1-0ubuntu2 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Wed Jun 14 14:58:08 2023 DisplayManager: gdm3 InstallationDate: Installed on 2023-05-20 (24 days ago) InstallationMedia: Ubuntu 23.04 "Lunar Lobster" - Release amd64 (20230418) ProcEnviron: LANG=de_DE.UTF-8 PATH=(custom, no user) SHELL=/bin/bash TERM=xterm-256color XDG_RUNTIME_DIR=<set> RelatedPackageVersions: mutter-common 44.1-0ubuntu1 SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2023776/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
