Hello Daniel, I apologize for the huge delay, but I have been experiencing a number of show stopping issues that I have yet to recover from.
As written above: After all the issues that I had with Ubuntu 23.04, I decided to "downgrade" to Ubuntu 22.04.2, which was working just fine at first, see comment above. I was using the recommended and "tested" Nvidia driver 525, which was the one that the Ubuntu additional drivers tool suggested. Recently Nvidia released the proprietary Nvidia driver version 535, which was made available via Ubuntu 22.04.2. So I ran the Ubuntu system updates utility like I usually would, in the hopes of Ubuntu picking up the newest Nvidia driver automatically, like it has always done in the past. Ubuntu did find and suggest to install the new Nvidia driver, but... Just like on Ubuntu 23.04, Ubuntu 22.04.2 also mentioned something about a "partial upgrade", see attached screenshots below. Trying to click on "continue" instead didn't offer any updates, so I went back to the "partial upgrade" option, because my system wasn't getting any updates whatsoever ever since this "issue" appeared out of nowhere. In the middle of the "partial upgrade" my 22.04.2 system went black, meaning all of my screens turned off randomly, and the computer would not react to any user input whatsoever. After being forced to perform a hard reboot, the computer did not want to boot, spitting out several "journal errors" during the boot process. I would like to mention that this was a fresh install of 22.04.2 - not a single ppa etc. was added manually - just a handful of native apps installed as Snap via the official Ubuntu Software Center (including Steam, also installed via the Ubuntu Software Center). I hardly used the system, because I was still in the process of transferring over the data that I had to recover from my busted 23.04 install. A few notes here: - this happened totally randomly - previous system updates were completed without any issues whatsoever - there were no issues whatsoever before the new Nvidia driver 535 - the partial upgrade option mentioned a bunch of Nvidia 535 modules to be installed - and the old 530 driver to be removed - and it also mentioned a ton of other things to be updated as well, including the kernel and a bunch of Ubuntu desktop files Digging around I found out that both this and the low latency kernel subject is a common and repeating issue: - https://askubuntu.com/questions/1443779/why-doesnt-this-software- updater-warning-tell-me-what-is-going-to-be-installed - https://www.reddit.com/r/Kubuntu/comments/14ndb7a/why_do_i_keep_getting_these_oracle_and_lowlatency/ - https://askubuntu.com/questions/1334791/not-all-updates-can-be- installed-in-software-updater - https://askubuntu.com/questions/725481/ubuntu-software-updater-not- all-updates-can-be-installed - https://www.google.com/search?channel=fs&client=ubuntu- sn&q=ubuntu+nvidia+partial+upgrade Verdict: Now I have to recover my freshly installed 22.04.2 system again, just like I did with 23.04 a few days ago. Since I don't have the time to troubleshoot this yet again, I am now forced to go for a clean install again, but I will be using a different distro this time around as it seems that even Ubuntu LTS has become highly unstable / unusable for Nvidia users. This is extremely aggravating to say the least. This entire ordeal will set me back another one or two weeks at the very least. Been an Ubuntu user for decades now, and recently switched from AMD to Nvidia gpu, and it's been nothing but trouble thus far, sadly. Using an AMD gpu was flawless for the most part, but on Nvidia it's one headache after another on Ubuntu. -- 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
