[SOLVED]Journalctl error about nvidia-uvm

jojo06 · 2023-11-25 23:04:49

First let me ask you, I'm using sway, why do I need to use nvidia_uvm when using nouveau ? Or should I ? If it's a warning/error that we should ignore then no problem.

journalctl -b | grep "nvidia"

systemd-modules-load[224]: Failed to find module 'nvidia-uvm'

lspci -nnk | grep -iA2 vga

01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] [10de:1c82] (rev a1)
	Subsystem: eVga.com. Corp. GP107 [GeForce GTX 1050 Ti] [3842:6255]
	Kernel driver in use: nouveau

--
	Subsystem: eVga.com. Corp. GP107GL High Definition Audio Controller [3842:6255]
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel

There was kernel modules for nvidia, i changed it to nouveau only. I might be also removed uvm from kernel modules.

You most likely have nvidia-utils installed?

jojo06 · 2023-11-26 18:42:39

Yes, I just checked. It came with the update, I thought it must be a necessary installation for nouveau. Even if I uninstall it, it will install it again with the update. What if I add it to 20-nouveau as blacklist nvidia-utils?

What update? If you are able to uninstall nvidia-utils without breaking any dependencies why would it be reinstalled again when you next update the system?

jojo06 · 2023-11-26 20:20:47

Pacman -Syu update, I don't understand it either. I uninstalled Nvidia. Noueveau is installed and that's what's used. That's how it's set in the kernel. So I guess there's a dependency left, as you say. How can I check this and remove it correctly?

loqs · 2023-11-26 21:09:50

If a package depended on nvidia-utils pacman would refuse to remove nvidia-utils without removing that package in the same transaction. You could examine /var/log/pacman.log to see what was in the same update that pulled in nvidia-utils.

Does that mean you removed the nvidia package without removing nvidia-utils or any other nvidia related packages?

Not if you installed nvidia-utils as that will blacklist nouveau.

pacman -Qs nvidia
lsmod | grep nouveau
cat /var/log/pacman.log | curl -F 'file=@-' 0x0.st

@loqs Yes, I uninstalled nvidia directly without removing any dependency, but as you said, if there was an dependency, it would not allow it. But I was able to uninstall it, if utils warned me, I must have uninstalled it too. But perhaps in the end there is an addiction.

@seth That's what it did and then I moved the `blacklist nouveau` line to the `#` comment line

pacman -Qs nvidia:

You've never removed nvidia-utils and nvidia-settings, only nvidia.

jojo06 · 2023-11-26 23:55:45

Yes, I was surprised. I looked with pacman -Ss and now I see it installed. Should I remove it with -R or -Rsnc? Is it better to do it with 2 separate commands or in one command line to avoid any conflicts/dependencies?

seth · 2023-11-27 07:22:50

You should understand what those do, https://wiki.archlinux.org/title/Pacman … g_packages and you can remove as many pacakges in one command as you want.

jojo06 · 2023-11-27 20:50:54

Yes, I looked. I think Rsc is fine. `egl-wayland` (opengl-wayland of nvidia perhaps?) was the first thing I found when I typed it in the wiki. `libxnvctrl` (xfce for detect nvidia) and I can't find what that is: `eglexternalplatform` was removed along with it. I'm glad you reposted the link, I guess you have to repeat it every now and then.

Quick question, does the `pacman -Rn package_name` command only remove the configuration without creating the pacman backup file or does it also remove the default configuration in the .config?

seth · 2023-11-27 21:06:11

I'd think twice about "c" being "fine" - or necessary.

https://man.archlinux.org/man/core/pacm … OPERATIONS
https://man.archlinux.org/man/core/pacm … PLY_TO_-R)
What does it say about the "--nosave" switch behavior?

Stuff in your $HOME/.config principally won't get touched, if you meant that.
It's all only about files under control of the package manager, not your personal data (incl. configs)

jojo06 · 2023-11-27 21:45:30

Yes it is necessary. Otherwise there will either be an idle dependency or/and the need to install.

Thank you again seth

seth · 2023-11-27 21:51:22

No it is not and there will be not.
Compare the packages suggested for removal between "-Rs" and "-Rsc" and use "c" with outmost care only.

jojo06 · 2023-11-27 23:08:05

I see, so it depends. As I said, I queried the packages from the wiki, and I realized that these packages related to nvidia I used with -c. I will compare and double check for everytime for "c" got it.
