[Mint 22.3] AMD firmware update 0ubuntu3.4 breaks graphical boot (github.com)

So I'm in this predicament too, I didn't notice the warning about this update breaking my card and I've just gone through a full reinstall - didn't have timeshift installed, so I'm kind of gutted. Getting that sorted now so it's an option going forwards.

My question is, how do I go about downgrading to the prior firmware that isn't broken? And should I update back to the newest kernel?

Sometimes I feel like I'm getting the hang of Linux, and then something like this comes up and I immediately realise how very little I know. I'd be extremely grateful for any guidance.

Yeah you caught me, I've been a little frantic trying everything for hours before finding that bug report. Got sloppy and dox'd myself.

I'm able to boot into a full normal XFCE session after ruining my day with a full reinstall. The only weirdness is that I'm locked into using the onboard graphics processing on the CPU, which limits me to one monitor at 1024x768. But the monitors are still plugged into the non-working GPU. No idea how that works...

NV48? I didn't know what that was, mine's a 9000 series AMD card. This is definitely the first time I've had any issue with it, this build has been running like a dream since I put it together a few months ago.

Someone else just replied with a reddit thread about this: https://www.reddit.com/r/linuxmint/comments/1xo6jg2/for_those_affected_by_the_very_recent_update_from/

The upshot seems to be that Ubuntu is rolling out a fix on their end, and it's due in about a week? Am I getting that right?

I'm going to finish trying the temporary fix they've described and edit this reply.

Edit: I did everything they recommended, but it's still not recognising my GPU. Not sure what to try now.

    sorry, I'm talking in silly codenames. NV48 refers to Navi48, which is the graphics processor codename for the 9070 series. I keep taking nomenclature for granted, but your fastfetch (for example) may also communicate similarly for your dgpu

    with that said, your display output from that CPU's igfx should be able to render at your native res.If you're suggesting it's rendering from your iGPU despite your external displays still being connected to the dGPU? I'm not really sure if that would be the case. it could be doing something like cross-adapter scan out, but I'm wondering if it's just render at standard vga rest from the discrete graphics instead? in any case, I'm a little worried you might be getting done over a little by dated packages given you have the most recent hardware available. I didn't realise the kernel was so far behind on Ubuntu, though 7 should generally be okay.

    I really don't like to recommended this or remotely position this as a solution, but could you please try a fedora 45 workstation live USB? You can find a spin that also uses Mint's Cinnamon desktop environment. Please let us know if that at least offers you ootb support for your hardware

    In lieu of that, I think you might actually be able to download and install PPAs which back port newer software for better contemporary hardware support,

    I'm prepping a live one right now. I don't hate the idea of distro hopping at this point, the whole rationale for Mint was "it's not owned by canonical and it just works", so I'm a little less in love as of today. I'll be off to bed in a minute but I'll write again with how it goes with fedora. Going to try KDE Plasma for a change. Wish me luck!

    i remember your post from a while back regarding the parts you'd like to use for a new build! i feel responsible in some small way to get you up and running 😅

    i've been using fedora fully as a dumb guy for a good few years now and have had a great time with it. happy to help wherever i can.

    i also have a very similar config to you (R7 9800X3D + RX 9070XT) so we should have a fairly similar experience on 45 together.

    best of luck 😊

    As of this morning I am doubly in your debt. It's incredibly sweet to be remembered and looked after, thank you! In an age where computing is the means of production, it is a radical blessing to have a community like this making it free and open and supportive.

    Even from the live session it was snappier than Mint ever was. Even the tooltips are charming. So I took the plunge! AAAAAA!

    It took literally a couple minutes to install the whole OS, and I might actually get everything working again before I normally start work even. Insane! I'm overwhelmed at how good this is, I'm actually GLAD now that Canonical broke my GPU upstream from Mint, this is exactly the push I needed to try something new.

    Again, you rule. I'm literally misty-eyed right now. Thank you.

    Edit: Gasp it even has an advanced clipboard OOTB, this is huge for me. I love it so much.

    very happy to hear 😊

    please make sure you grab the codec packs from the software store. There's a philosophical reason as to why they're not included by default, as they don't like to ship non-free sw in the base image, but these will allow for proper video playback. you should be able to find them in their own little section

    other than that, enjoy your pc, hit us up if you need a hand with anything
