PC not booting; several "Failed to start NVIDIA Persistence Daemon" lines

[versed sierra]

i get this right after the manufacturer logo screen every time I try and start the pc

im using kubuntu rn

i would send the neofetch stats but i cant

since i cant get in the pc

[tribal quartz]

Has this started happening after an update? How did you install nvidia drivers?
This is clearly an nvidia driver issue

[versed sierra]

i had been having driver issues hes

yes*

i got my drivers through settings > driver management

i dont remember if this was after an update or not

from what i saw on google

[tribal quartz]

You could try this, but I'd also definitely recommend backing up your data as reinstalling may be the simplest option

[versed sierra]

i have nothing to really lose data wise

i just use steam and websites

ill check that page out

[tribal quartz]

If you have nothing to lose, then a reinstall may be quicker than banging your head against the wall trying to fix it if you can't find a solution tbh

[versed sierra]

the problem is that

me getting kubuntu was a reinstall that i did because of pc issues

idk if reinstalling again will help

i may just be stuck with the same problems

[tribal quartz]

What kind of issues?

[versed sierra]

idk linux mint was just being annoying

my sound kept not working

and steam wasn’t

so i got kubuntu

and it worked way better until this

btw

i was following the steps

but “root - Drop to root shell prompt” is not in the advanced options

[tribal quartz]

Try recovery mode

Perhaps moving off a Debian base would do you better since both are built ontop of it. Fedora is solid

[versed sierra]

thanks it was in there

[jaunty mica]

Krabomancer received a thank you cookie!

[versed sierra]

im trying to follow the last steps

[versed sierra]

thanks thanks thanks thanks

[jaunty mica]

You're thanking too much ó_ò

[versed sierra]

idk which to go with

does it matter

[tribal quartz]

I use GDM personally, if you chose to install GNOME then that's probably best

[versed sierra]

i went with it and

it did all this

and has stopped i think

should i just reset now and try to boot

[tribal quartz]

Worth a shot

[versed sierra]

so uh

my desktop did

not look like this

[tribal quartz]

Oh you were on KDE? you installed GNOME. You can install KDE then switch to it from the login screen

[versed sierra]

how do i do this

sorry im not too knowledgeable on these things

[tribal quartz]

I think something like
sudo apt install kde-full

[versed sierra]

done

how do i apply it to my pc

[tribal quartz]

Log out, on the screen where you log in/type your password, there's a gear in the bottom right corner. Select KDE xorg from there

[versed sierra]

so i did this and im in my pc now! but

im stuck in a resolution that looks super zoomed in and horrible

and it says it’s the only resolution supported

[peak remnant]

Well one of the wayland issues, why i don't switch to wayland

Okay just switch your session in login manager(login screen)

You're using gdm3 currently

?

[nimble blaze]

nvidia driver issue?

did u installed custom kernel or someting like that?

are u using dual gpu?

[tribal quartz]

They had an nvidia driver issue, had to go into recovery mode and use a root shell to purge drivers before reinstalling DE. I was half asleep and didn't notice/warn them about installing GNOME instead of KDE so I had to guided through installing KDE. Not sure if they got both KDE xorg and Wayland or just Wayland but I'm guessing it's a Wayland thing

[nimble blaze]

i see nvidia is really bad with wayland

[tribal quartz]

Yup, well usually so. Sometimes you can get away with it but in my experience I only got it working once

@versed sierra when you're on the logon screen, where you selected between GNOME and KDE, what are all the options available to you in there?

[versed sierra]

i am now available again

[versed sierra]

lemme see

Plasma (X11) and Ubuntu

plasma x11 is the one that makes my home screen look normal

but both are really zoomed in regardless of my choice

[peak remnant]

you can use screen scaling for that

[versed sierra]

@tribal quartz sorry for ping but i just wanted to check and see if you saw my response earlier

just wanting to get my pc fixed soonish if possible bc i have some online work and its annoying on mobile

[tribal quartz]

I don't have a solution to your predicament. If you absolutely require a working PC I'd advise reinstalling instead of trying to fix this installation

[versed sierra]

ah

fuck

alright

[versed sierra]

which distro did you recommend again

[tribal quartz]

Fedora

[versed sierra]

alright

i vaguely remember how to install a new os i think

i have a usb with kubuntu on it, last time someone helped me get ready for a reinstall they had me get some app that can zap files on and off of usbs

how can i clear this usb and put fedora on it

[tribal quartz]

You can download Ventoy, follow the steps in the read me to install it onto the USB. Then simply drag and drop the Fedora iso onto the USB. Reboot your PC and you're set

You can download Ventoy from their main site

I'd assist more but I'm deadass tired. If you need further help you can ask how to do this in #support-general I'm sure someone can assist

So nvidia drivers failing to work after an update is a very common issue - the problem is usually that if the kernel updates to something unsupported by the driver, the Nvidia driver will fail to load and you'll end up at that screen, at a low fallback resolution. ctrl-alt-f2 will switch to a TTY, where you can login and type in commands to attempt to fix this, if you run into this problem again.

IMO, the better solution is to instead use the nvidia-dkms driver, which will generally work regardless of kernel version. This applies to most distros. I'm sure there's some reason that isn't what distros just ship with by default if they are prone to this problem, but I'm unaware of why and am aware that this often solves people's Nvidia driver problems for good.

[shut musk]

As far as distro goes, I feel like Nobara KDE would probably suit you fine. Fedora base, handles all this driver bullshit for you well, and of course it uses KDE which you are familiar with. It is intended to function as a gaming PC out of the box. However, it only supports vaguely modern-ish Nvidia GPU's - I assume you're using like maybe a 900 series, 1000 series, or later. You're unlikely to be using such an old card that it isn't supported if you're on a gaming discord, but it's wroth mentioning.

Kinoite might be a better option if you're after something particularly bulletproof, though it lacks many of the optimizations of Nobara and requires a bit more setup.

Neither of these are necessary if your current distro is working fine.

[shut musk]

As for Wayland, Nvidia support for Wayland is fine enough to function as a daily driver for most use cases. GNOME uses it by default even for Nvidia, KDE handles it just fine now, and X11 isn't really being maintained and will need to be swapped out at some point. I would not worry too much about that discussion, use what your distro ships with and they'll manage switching you over when the time comes if necessary. It's unlikely this had anything to do with Wayland, it's just Nvidia drivers being a pain in the ass and most distros not shipping with the DKMS drivers to avoid such issues.

[tribal quartz]

I heavily stray away from recommending Nobara as it's a one man dev team with questionable decisions. They compromise stability, security and compatibility in an attempt to squeeze a few more fps.

The performance is negligible compared to the problems that arise from using it. It's just a heavily modded system you can't assume any Fedora packages will work and I seen plenty of people unable to play games on Nobara that would run ootb on most other distros
