Try lts kernel

sudo pacman -S linux-lts linux-lts-headers

Use advanced from grub and try this kernel.

sudo nvidia-settings

Additionally, this final symbol means a reboot is pending after the last update.

I tried sudo nvidia-settings but it returned nvidia-settings: command not found

5

I had to go to sleep, restarted the machine and nothing much has changed

6

question, when you say advanced from grub is that from garuda assistant?

7

In the advanced menu at boot time (grub), you can select what kernel to use.

hit alt+space and search for Nvidia, and click on Nvidia X Server Settings from the list.

I executed the kernel command as well, do I need to restart after also going to garuda boot options and changing it to garuda linux with linux lts?

9

If you installed the kernel, and selected it from the advanced boot options in grub, you should be now in the kernel selected. This is only active for until next boot as it does not set a new default.
You can check what kernel you are running currently by checking your garuda-inxi

Just noticed this is a fresh installed system. Could we get a new garuda-inxi after you restart? (↻ means you haven’t restarted after an update). I’m a bit curious to see if that falied unit will go away.
Just forgetting to restart after the first update could of been your problem.

That’s weird… it should be linux-lts if you selected it at boot. You sure haven’t rebooted again and forgot to select it again? (as I said before, it is only for that boot. It doesn’t set a default)

at least there are no failed units now :grinning:

I’ll do that in a sec, also nice!

18

It’s stuck on loading initial ramdisk for a while, should I wait further?

19

Usually that means there is an error booting (or booting using a specific kernel)
If I had to take a guess it might be because DKMS packages, but you can never be sure. Check this FAQ Computer doesn’t boot, boots to a black screen, or stops at a message

If that doesn’t help, try a kernel you know that works (for instance the Zen one; which it should still default to). If that still doesn’t work, you can select a snapshot from a time the system was working Restoring snapshots to get the system back to working state | Garuda Linux wiki (after you follow that guide completely and do your reboot for it, made sure to update your system again with garuda-update )

Is the monitor still reporting as unknown after the reboots?
Do you know the specific make of the monitor and how your are connecting to it (like what cable type)?

I’ll take a look at the FAQ, the monitor is a curved Sceptre 75hz, connected through an HDMI cable
