Nouveau bus: MMIO write of fault at xxxxdx [ privring ]

[violet nest]

I have been waiting on this screen for a long time, i dont know if i should let it keep going and it will fix or is it a lost case, i have been suggested to update the driver but how can i do that if this screen keeps going on

[finite flame]

Is this a newer computer?

Is Mint installed or running from USB?

[violet nest]

Its a old one, i dont have my new laptop rn to create a new usb boot otherwise i would have just started a new system

[violet nest]

Mint is installed in it, its been running smoothly for a month before this

[finite flame]

Can you power it off and use grub menu/advanced options to boot an older kernel?

[violet nest]

I will try it right now i dont know how to do it but i am sure yutube will help in doing that, thanks for helping really appreciate it even if it don't work (also sorry for the late replys i am in a online class )

I am in grub but i dont know where to go from here now i searched and all command they give dont work and it show cant find command sudo

[dense river]

please take and upload a picture

[dense river]

type normal

then press arrow down to enter advanced options and select the 3rd option

[violet nest]

I typed it and when i pressed enter it loaded a bit then took me back to the error screen

[dense river]

can you get to the menu that says "start linuxmint" and stuff, then press e. find the linux line, after the words quiet splash, add rd.driver.blacklist=nouveau and press f10

[violet nest]

I will try it right now, tried it once to get in that but did not work as it loads me in linux mint instantly without the option to choose which system to load but i will still keep trying

[violet nest]

Like this?

[woeful gulch]

am facing this same issue too

[violet nest]

Good to know i am not struggling alone lol 🤣 😭

[woeful gulch]

[violet nest]

Note: still did not work i pressed f10 and after the loading its back to the same error screen like before

[wind musk]

Not to barge in but you might have the same issue I did with a recent update to libpciaccess0. My web travels have indicated this affects both NVIDIA and AMD GPUs

I am crossposting this here from someone else who found a quicker way to sort this out.

1. Check if the old version is still on your system:
   apt-cache madison libpciaccess0

2. Downgrade it:
   sudo apt install libpciaccess0=0.17-3build1

3. Prevent it from being auto-updated until it's fixed:
   sudo apt-mark hold libpciaccess0.

If you have a timeshift recovery and can get to a TTY to login, run timeshift --restore and follow the prompts after logging in via tty and restore to before the update, then run step 3 alone above\

[violet nest]

Thanks for the suggestion, yes i have a time shift recovery but i am not able to get into TTY as i can only acccess grub that not helping much or it just starts to boot into mint instantly and the error screen with the fault start to appear

[wind musk]

Do you have a bootable mint USB? That would be my other suggestion as I think you can access time shift backups from that

[violet nest]

Yes i read about that, thats the only problem i dont have a boot usb otherwise i would have just started from scratch as i have all my files backup externally, i was planning to visit my neaby cafe with computer to make a live usb there, but dont know how that will go

[wind musk]

Other idea is maybe set nomodeset in grub before booting the kernel. I can't remember what part of grub that's in (I think the option to edit the command line)

I've only heard nomodeset might help. Never got a chance to test it myself

[violet nest]

Well will test is out now, i never used grub as much and its commands are breaking my mind but i will try

[wind musk]

Gimme one sec and I'll post a guide

Ok so basically you're going to press E on the grub entry you want to edit before boot.

From there there should be something that says

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

Change the "quiet splash" to "nomodeset"

This will boot it without the splash/mint logo and will set the nomodeset parameters for your boot. This may cause a slightly ugly resolution and might cause lack of suspend options.

This is only temporary and will revert on next boot

If this allows you to boot into Mint I would run the commands I posted earlier to downgrade libpciaccess0.

I am heading to bed but I can try to help more if needed toomorow

[violet nest]

it worked it worked hurrya, thanks a lot to everyone for giving me step by step instructions for everything i would have not been able to solve it if it was not for you guys helping me out

[violet nest]

also thanks for the guide, i would have just spend hours finding how to do it and still would have not find the right one 🤝

[violet nest]

i hope you were able to solve it by now if not maybe try the instructions others gave here and that might help

[wind musk]

Yeah no problem!

[woeful gulch]

thank you cinnamon

i used timeshift as well and used the commands u said
now its working!

[woeful gulch]

yeah thanks to the community, was able to solve the issue

[wind musk]

Awesome! Glad to hear this

I do have further good news. Looks like Ubuntu has been working on this to fix it up

https://bugs.launchpad.net/ubuntu/+source/libpciaccess/+bug/2115574

It looks like a new package of libpciaccess is going into their proposed repo so I can download this later after I make another time shift backup and if it works I can report back.

[soft echo]

Sorry, How would i upgrade to new version of libpciaccess ver 24.04.2? I tried timeshift + above and nothing is working for me 😦 how would i download from noble-proposed or plucky-proposed im confused

I can log in via nomodeset fine, just trying to find a permanent solution

[wind musk]

I am planning on looking into this tonight

[soft echo]

Thanks! Hope i can fix this haha

[soft echo]

Thanks for the help. It wasn't working before but I updated some things after your first solution and it started working again. I still get the nouveau write off error message, but it stops after a few seconds and puts me back to the welcome screen instead of black. So still a success? I rebooted a couple times to be sure and its working again thanks!

[wind musk]

So I did try installing the proposed update directly from Ubuntu's website (Since I use the Ubuntu based version of Mint). It resulted in me having to use timeshift again as it caused a weird broken package issue (This is most likely my fault lol)

I've read on this page that it will be ubuntu's proposed repo for at least 7 days, and then if it is confirmed to fix the bug (Which the top of the site implies?) it will be released to updates. So I think that would imply we get the fixed version in a week or so?

https://bugs.launchpad.net/ubuntu/+source/libpciaccess/+bug/2115574

Also I hope that JeremyB did not mind me helping out here. I didnt want to step on anyones toes

[woeful gulch]

Thanks a lot cinnamon for helping us out!!

[wind musk]

No problem.

I was reading that launchpad today and it looks like the fixed update to libpciaccess0 should be hitting updates soon for Ubuntu and in turn Mint.

[woeful gulch]

The devs are awesome too for resolving this quickly.

[wind musk]

Considering how widespread this could gotten, yeah.

Also of note I noticed this morning the problematic update no longer shows up even if held/blacklisted for that version in Update Manager

[woeful gulch]

oh so mint team did something in the backend i think

[wind musk]

It may also be Ubuntu pulling the update from their repos. Standard mint does draw from those same repos

[thorn talon]

So yeah I have a tip in case you need to do this in the future

You can use your (Android, not sure about iOS) phone to make a bootable USB

There are apps on Google Play for this, best is probably the unofficial port of Ventoy
