[SOLVED] Gnome won't boot after Linux update

I run a 980ti and the standard Nvidia driver. Everytime the Nvidia driver updates, gnome won't boot and I have to use the live usb, mount, arch-chroot and sudo pacman -S linux to fix the problem.

The system boots as expected after this process. I'm running the default kernel and the regular Nvidia driver, 455 I think. The problem has been going on for a few months now.

I have tried to pacman -S linux before rebooting, but it doesn't seem to matter, if Nvidia updates, I'll need to use the live usb next time.

Is anyone else experiencing this issue?

Re: [SOLVED] Gnome won't boot after Linux update

The nvidia package updates because of and in lockstep with the linux package. They always should come together. It sounds more likely that your fstab is wrong, mounts something into /boot that you aren't booting from your bootloader thus you have a kernel/module mismatch when that combination happens that you "go fix" by chrooting into your install (which doesn't mount the wrong /boot ) and reinstall the linux kernel at the place your boot loader does actually check.

Re: [SOLVED] Gnome won't boot after Linux update

I managed to catch the boot error "Failed to start load kernel modules."

In journalctl

Trying to figure out how run:
systemctl status systemd-modules-load from that boot since when I can run this, its on the now working boot.

In the mean time. nvidia 460 dropped, and I had the same problem happen again. The next time Nvidia updates, I'm going to disable gdm before I reboot so I can run systemctl status systemd-modules-load to get a better error message and hopefully figure out whats causing this.

Re: [SOLVED] Gnome won't boot after Linux update

compare uname -a and pacman -Q linux (or -lts or whatever you are using) as well, you are likely not going to be on the kernel version you updated to and should be booting.  What boot loader are you using what's it's configuration and maybe post your fstab and

lsblk -f

(and please use

[code]code tags[/code]

) for pasting output.

Re: [SOLVED] Gnome won't boot after Linux update

With the latest linux update it happened again. As I was digging through your suggestions I realized /boot isn't in my fstab.

I don't have a way to test if it's fixed until linux updates again (without downgrading), but I'm 100% sure this is the issue.

Thanks for your help. I wouldn't have been digging around in my fstab and realized /boot wasn't mounted when my system was running normally.
