[SOLVED] System broke after Nvidia drivers (and Optimus manager if it

I installed my system with archinstall yesterday (dual boot) and it all went fine. I installed a different DE, awesomede, afterwards and it all worked fine.

Today, I installed the necessary proprietary Nvidia drivers for my graphics card (RTX 3050 mobile) using DKMS and afterwards Optimus Manager. I rebooted after being prompted to and reached a black screen with a blinking dot.

Since then, I've been at a loss. I've downloaded and removed packages, modified config files both manually and automatically, added boot parameters, and the list goes on, to no avail.

I'll gladly provide any other necessary files.

Re: [SOLVED] System broke after Nvidia drivers (and Optimus manager if it

we cant really help with no details on what you've done.... not really sure why your using dkms either ?
i would undo everything youve done and follow this page, and use "prime render offload" as its the officially supported way for your hardware.

Re: [SOLVED] System broke after Nvidia drivers (and Optimus manager if it

There's no record of optimus-manager in the journal, nvidia and i915 modules load fine and

looks more like either the KMS is late or you added a bogus xorg config (w/ either nvidia-settings or nvidia-xconfig)
=> check/post your xorg log, https://wiki.archlinux.org/title/Xorg#General

I've downloaded and removed packages, modified config files both manually and automatically, added boot parameters, and the list goes on, to no avail.

You do understand that this line is just drivel and contains absolutely no information whatsoever?

Re: [SOLVED] System broke after Nvidia drivers (and Optimus manager if it

Hey, thanks for offering to help!

You do understand that this line is just drivel and contains absolutely no information whatsoever?

I added that part to show that nothing's off the table and the issue could be anywhere, though I apologize if it came off in a different way!

In any case, I've added below my config and log file:

xorg.conf
Xorg.0.log

Re: [SOLVED] System broke after Nvidia drivers (and Optimus manager if it

you added a bogus xorg config (w/ either nvidia-settings or nvidia-xconfig)

And the first step will be to get rid of that because

[     7.775] (II) NVIDIA(0): Validated MetaModes:
[     7.775] (II) NVIDIA(0):     "NULL"
[     7.775] (II) NVIDIA(0): Virtual screen size determined to be 640 x 480
[     7.775] (WW) NVIDIA(0): Unable to get display device for DPI computation.
[     7.775] (==) NVIDIA(0): DPI set to (75, 75); computed from built-in default

you're configuring the server to run on the nvidia chip, but there're no outputs attached to that GPU.

The other problem is

[     6.247] (II) LoadModule: "intel"
[     6.247] (WW) Warning, couldn't open module intel
[     6.247] (EE) Failed to load module "intel" (module does not exist, 0)

You're referecing the intel driver (in some other file) but that driver doesn't exist (possibly a residual from the optimus-manager installation)

grep -ri intel /{etc,usr/share}/X11/xorg.conf*

Get rid of that, too. Then follow the link that jonno2002 posted.

Re: [SOLVED] System broke after Nvidia drivers (and Optimus manager if it

Thanks a ton for the help, post marked as solved.
For the record, it seems Optimus manager is at blame for this. Installing it makes my now function system not boot, and removing it immediately fixes the issue.
