RIP. Time to pull out the backup, amiright?
right... the backup...
The backup specifically created for recovery…
The recovery backup...
Designed to backup the recovery…:
That backup?
Recovery's backup
Blessed be CachyOS for setting that shit up for me automatically.
While I agree snapper (what CachyOS uses) I very useful, it is important to draw a distinction between snapshots (snapper) and a proper backup tool (borg or restic). Snapshots are usually stored on the same drive, so in the event of a drive failure/corruption you are still very fucked. Proper backup programs also have other important features, like the ability to select remote locations, setup encryption, etc. DO NOT rely on snapper to (always) save your ass.
That being said, I fucking love snapper and it was the main feature I was missing from openSUSE.
Distro hopped recently. Loving it.
Now I get to say "I use Arch, btw" while still having nfi what I'm doing.
I like diving into the deep end and drown a few times too.
Have you heard of .pacnew files yet?

You need a couple things:
- The kernel driver (dkms)
- Userspace component
- Kernel headers (for dkms)
First get your kernel headers, this is easy enough, but varies based on which kernel you have installed. The format of the package name is {kernel}-headers. If you have the linux kernel, get linux-headers. If you have linux-lts, get linux-lts-headers. If you're not sure on this, the command pacman -Q | grep linux searches for installed packages containing linux in the name. If you have multiple kernels installed, get the headers for all of them.
Then install (from AUR) at least nvidia-580xx-dkms (display out) and nvidia-580xx-utils (Acceleration, like 3D and video decoding). If you have Steam or play Windows games under Wine, be sure to get lib32-nvidia-580xx-utils too.
Also of note is the order in which you install things. Having the kernel headers installed is important for the DKMS modules to install succesfully. If you already have nvidia-580xx-dkms but were missing your kernel headers, you should reinstall it after installing your kernel headers.
I keep hitting my face on the fact that DKMS modules somehow don't depend on the kernel headers and these have to be installed manually. This happened to me both in Arch and in Debian.
Why does everyone seem to think that this makes sense?
You have btrfs and snapper, and just roll back to a working version in the grub menu, and install the legacy drivers before it all goes wrong
I have ext4 and efistub, and the attention span of a squirrel.
I have never before felt so much kinship from a single comment.
I started to read your comment, but there's a car 100 metres up the road...
Sell nvidia and buy amd.
Already bought intel. I am quite fond of the B580.
Boot into a live boot install of some distro on a USB drive.
I did try that as well. The legacy drivers did install from the tty, still the system doesn't see them, for lack of a better word. It is not a big issue though. I had already planned on upgrading since my current setup is very old.
Half of the new components have already arrived. The current PC will become a little home server running either Ubuntu or Debian most likely.
I just thought the situation was funny.
Did you also uninstall all of the components of the new driver as per the arch site?
Otherwise it's investigate from the tty as to what driver, if any is in use for the gpu pci device.
Yessir. I did remove everything that was from the 590 driver before I installed everything from the legacy 580xx. I might have to load a kernel module somewhere, maybe. But the effort is not worth the payout. My data on the machine itself is not unrecoverable thankfully.
I have a 3080, so 590 is fine for me. But, I'm sure the legacy one is a dkms. But the process of installing that should be done as part of the install. E.g. you install, reboot
What does lspci -k show for the card in terms of Kernel driver in use, and kernel modules?
Also what does dkms status say?
If the module is installed and showing in dkms status and showing as used in lspci -k, it should be available for desktop environments.
I do agree in terms of effort when things go wrong though. I remember when I was a lot younger and I had no problems just sitting in front of my keyboard finding whatever the latest problem is. Now, I want to be doing things with my PC.
But, a bit of debugging might be worthwhile before doing a new installation.
Modern schoolkids don't read, so Arch should consider making 20-minute videos for every update. And a song like some of the *BSD.
Did you not see the news item you get before it allows you to start the update?
I was working on a little Intel NUC on the side that had memory issues. And during that I just sudo pacman -Syu on my main machine without thinking.
I did also read the announcement before upgrading which makes it even better IMO.
Did you uninstall the official driver first? That is, the nvidia package?
(shrugs) I haven't had an issue with my 1050ti or 4070 on Mint MATE. I did have issues with my AMD Phantom 2. YMMV
AMDs AMDingly
Oh man, I remember fondly the days of booting to no gui. Typing out error codes to another computer to Google.
I don't think I miss it. Linux has been super stable for me for a decade maybe, and I've been trying to game on it, so I used to have to fight with "faster" drivers all the time
"Doesn't help" is a bit unspecific for an actual answer.
I simply installed nvidia-580xx-dkms and nvidia-580xx-utils and that was all. If you did not already use the dkms-driver package before you of course also need <your kernel>-headers and dkms (but the latter should be pulled as a dependency for nvidia-580xx-dkms anyway)...
Which automatically asks for the removal of nvidia-open (the standard package for the base linux kernel) or nvidia-open-dkms and nvidia-open-utils that replaced the earlier nvidia, nvidia-dkms, nvidia-utils packages when 590 hit.
PS: If you still have stuff using 32bit add (you might have guessed the scheme by now...) lib32-nvidia-580xx-utils to replace lib32-nvidia-open-utils

Dropping an extensive explanation and how-to is a meme.
Using arch is the first mistake.
Why?
I don't think its an Arch issue. But on a system that has snapshots or generations or whatever Silverblue term is then the 30s remedy is reboot to an old snapshot
This can actually be done with any fs that supports cheap snapshots
