An update.

So, mesa received a 25.0.0 update on feb.09th and I've been waiting since for it to be included in arch packages but nothing yet. Today I got impatient and built both mesa-git and lib32-mesa-git packages (currently on 25.1.0._devel versions) using yay.

So far, I've tested it scenarios which usually crashed the system and there were none. Let's hope V25 resolved the issue.

can anyone tell me the proper way to downgrade those two packages? That, and/or the proper way to go about downgrading them.

There are two methods that I know of.

1.) Using older downloaded packages.
Check if you have mesa and lib32-mesa packages in your pacman cache: (If you still have these then lucky you.)

Code: [Select]

find /var/cache/pacman/pkg -iname "*mesa*"  2> /dev/null 

then follow: https://wiki.archlinux.org/title/Downgrading_packages

2.) Manual Compilation.

Note: freedesktop is currently on the process of server migration, might have issues on downloading the files. I did check and it worked fine as of posting this reply. Just a heads up.

I don't know about proper, but I did the downgrade on packages like this by cloning:

https://aur.archlinux.org/packages/mesa-git
https://aur.archlinux.org/packages/lib32-mesa-git

editing the PKGBUILD file's pkgver= (check the available versions on gitlab: https://gitlab.freedesktop.org/mesa/mesa):

Code: [Select]

pkgver=pkgver=25.0.0_devel.200052.bed748d5f6d.d41d8cd

to 

pkgver=24.2.7 (this is an example, choose the version you want on the gitlab site specified above)

To avoid problems you may want to set the PKGBUILD files as immutable: (I've had the issue where it would compile mesa as the latest version unless I did this.)

Code: [Select]

chattr +i PKGBUILD
to undo: 
chattr -i PKGBUILD

You may need to edit the dependency requirements too. Such as using an older dependency or add some missing ones.


Hope this works out for you. Cheers.

I didn't think the kernel needed downgrading) were what I followed the last time I tried to downgrade.

Downgrading the kernel isn't necessary(I assume you meant instruction 1.2 in the arch wiki (which is for when you have issues when you have updated the kernel)).

Step 1.1 is good enough for mesa / lib32-mesa.

Still If you want to try older kernel versions, you can just either just do step 1(from my earlier response, not the arch wiki steps), or use an lts kernel.

My problem, however, is finding my games failing to start after such a downgrade.

Partially downgrading mesa won't cut it; it's too important a component to not break stuff. You should downgrade the entire system to the last days of mesa-24.2.7 (just replace https://archive.archlinux.org/ with https://archive.artixlinux.org/).

After testing I can confirm that everything runs fine, in my instance of the problem, at least (AMD Ryzen related). Solved?
