Optimus Laptop, another GPU thread

Hi,

First off, great distro. Love it. Have been using it for 2 months now I believe and it is splendid.
I installed it in a dual-boot configuration and I have been Gparted more and more memory for my needs.

But now I have encountered some issues, lets start from the top.

Original issue: my monitor would not work. Tried it all. ended up following this guide:

And essentially installed proprietary drivers by downloading from nvidia etc. Probably not recommended but that was the only strategy that worked.

Everything was flawless after that untill I decided to dust off my steam account and launch PoE/DOTA2
Terrible lag, 20-30 FPS no matter proton version or if I ran Vulkan. Even tried to download standalone for PoE via Lutris, same thing.

Started to watch nvidia-smi to see how much gpu memory I was using. 1-1.5gb/6gb. (wtf)
Strange part was that MangoHud was showing a 100% GPU load so I knew something was off on both sides- Probably something wrong in the config file for MangoHud and something about the drivers for nvidia.

So, some research later i found another guide here on garuda forums:

Followed the guide, and took some valuable tips (with additional reasearch ofc)
Could not update the nvidia drivers due to conflicting files, probably due to the nvidia drived mistake I did previously.

So I had to pacman -S --overwrite "*" nvidia (packages) in order to make it work.
Kind of broke everything. Had to roll back a snapshot, and in order to make my monitor work I had to install nvidia drivers from the first guide.

So, I ended up making the scenario worse, nothing worked and I was back to square 1.
Refusing to re-install everything and taking the easy way out, I seek guidance.

Thanks!

Refusing to provide guidance with such a messed up installation, I seek you to reinstall.

Hey,Gotcha and edited. Thanks!

If you still wanna do this consider rolling back your setup to before following my guide. Then just remove all packages that involve nvidia. I recently switched to using drivers from nvidia-all from frogging family and what I did was use pamac to search nvidia and proceed to uninstall all the nvidia packages that were installed. Then I reinstalled proper drivers.

Takeaway from this would be to take a snapshot before you try anything you aren't sure of.

Of course a fresh install is always better.

Some people with Optimus laptops have reported issues with kernel 5.12 that were only resolved by switching to the LTS kernel.

I had recently installed Garuda Gnome on an optimus laptop. It was working. I then switched to KDE and it was still working. I then switched back to Gnome and it no longer works. I used zen kernel for each install.

The temporary solution I used (Due to time constraints) was to boot into UEFI firmware/BIOS setup via:

sudo systemctl reboot --firmware-setup

and switch from Optimus mode (In my BIOS it's called MSHybrid) to Discrete mode.

Note: This will obviously negate some battery-saving benefits. It doesn't mean that your integrated graphics are unusable. It just means you can't use hybrid mode.

After switching to Discrete mode, you may need to reinstall the proprietary driver or switch to NVIDIA mode after boot. I just reinstalled so that Garuda wouldn't install optimus manager and whatnot but you should be able to duplicate the discrete config pretty easily. If you need to know what any of my configs or packages are, let me know.

Good tips from everyone, will do a fresh install during the weekend. Thanks!
