From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Request for help, I broke some graphics (lemmy.one)

I broke some packages and I need help figuring out how to fix it.
I run Nobara and usually update via "Nobara Package Manager", however it ran into a problem:

Could not depsolve transaction; 1 problem detected:
Problem: The operation would result in removing the following protected packages: nobara-amdgpu-config

I found the solution on Nobara projects site: sudo dnf update --exclude=nobara-login --refresh && sudo dnf update --refresh
That did result in several packages begin updated, I just skimmed through the list but I remember some mesa stuff. After a reboot some apps render like in the picture - missing characters or missing text all together and flickering artefacts. I run things pretty out-of-the-box so not sure what I've done that has lead up to this, just care about gaming.

How can I troubleshoot this? Thanks in advance

I don't use Fedora/Nobara, but seems like you can see the update history with: dnf history list

I've found this guide for rollback here: https://www.baeldung.com/linux/dnf-history-rollback-vs-undo

That is helpful, I'm not sure what I'm looking for yet though. But another comment lead me into antialiasing and this line in the history seems plausible.
install -y /tmp/zenity/nobara-amdgpu-config/fedora-amdgpu-pro/packages/amdamf-pro-runtime-5.4.3-4.fc37.x86_64.rpm /tmp/zenity/nobara-amdgpu-config/fedora-amdgpu-pro/packages/amd-gpu | 2023-04-25 20:11 | I, O | 11

Undo didn't work though:

sudo dnf history undo 11
Error: The following problems occurred while running a transaction:
Cannot find rpm nevra "amd-gpu-firmware-20230404-149.fc37.noarch".

So I made a rollback to my last know stable point: sudo dnf history rollback 2
It didn't exactly workout either unfortunately:

Transaction history is incomplete, before 73.
ransaction history is incomplete, before 72.
Transaction history is incomplete, after 71.
Transaction history is incomplete, before 61.
Transaction history is incomplete, after 60.
Transaction history is incomplete, before 8.
Transaction history is incomplete, before 7.
Transaction history is incomplete, after 6.
Error: The following problems occurred while running a transaction:
Cannot find rpm nevra "ImageMagick-c++-1:6.9.12.82-1.fc37.x86_64".
... many lines more about pkgs not found

I'll do a reboot and see what actually took effect. Atleast I'm learning something, maybe I should do all my upgrades via dnf instead of the manager in the future, easier to know whats going on.
