[SOLVED] Cannot upgrade system

I'm running the 5.4.79-1-lts kernel on an HP Laptop with an Nvidia 1050 and Intel graphics, running on Nvidia with Optimus.
A few days ago I tried to run a pacman -Syu on my system and after reboot nothing would work, I get past GRUB but then all I see is a blinking cursor for a few seconds, then my screen turns black, then the cursor again and so on. I can't even get to a TTY.
I could chroot from a flash drive but could not start lightdm from there, again, eternally blinking cursor.
I restored to an earlier timeshift snapshot and now everything works, but the system is very out of date.
I tried adding "nvidia-drm.modeset=1" to the GRUB kernel parameters as suggested in this post but had the same results.

Re: [SOLVED] Cannot upgrade system

Sounds as if the DM is insta-crashing, update, fail, boot the multi-user.target (2nd link in my signature) and check the journal of the *last* boot.
If you're using GDM, there've been a couple of recent threads.

Allright, upgraded and rebooted. Not sure if this is what you meant by last boot's journal tho.

Looks like yo need to rebuild optimus-manager because python was updated 3.8 to 3.9

Re: [SOLVED] Cannot upgrade system

Thank you! optimus-manager seems to be out of date, but installing optimus-manager-git seemed to solve it.
