optimus-manager VS grub-btrfs

See the discussion on Github at https://github.com/Askannz/optimus-manager/issues/543

Read: NVIDIA Optimus AND optimus-manager documentation thoroughly.

Use Nvidia to render everything. You can easily do this with programs such as Optimus Manager or Envycontrol (I recommend the latter if you're on wayland). You can set it so that when you're on charger, laptop boots with the Nvidia (dedicated) mode and when you're on battery it boots with integrated mode (if you do this, read the wiki about Nvidia as you're going to possibly experience nvidia-related issues).

I have installed optimus-manager few hours back(I'm in NVIDIA propitiatory). Read this https://github.com/Askannz/optimus-manager/wiki/A-guide--to-power-management-options and came to understand that manual configuration is necessary for turning off the nvidia card completely. Tried : Configuration 1 : dynamic power management inside the NVIDIA driver (Runtime D3 power management) Configuration 4 : acpi_call. But none is completely turning off the NVIDIA card even though I ran optimus-manager --switch integrated (applicable to only config 4).

What you meant was optimus-manager program and you should look at https://github.com/Askannz/optimus-manager for instructions with that method of using Nvidia Optimus, but you should also look at instructions for other methods for Nvidia Optimus too, especially PRIME-Render Offload one, because you can find important things for power management at https://wiki.archlinux.org/title/PRIME#PCI-Express\_Runtime\_D3\_(RTD3)\_Power\_Management , because you have a Turing GPU and Tiger Lake CPU, and method for Nvidia Optimus you mentioned and want to use is best supported with gdm, sddm and lightdm display managers and you may want to look at other Nvidia Optimus methods.

Just asking because I wanted to give some advice and it would be different between a desktop and laptop. There are some options to manager graphics through a gui like optimus manager. PopOS also comes with some extensions to manage it out of the box. You can also look at using Lutris for gaming, you can use it to make every game launch with your discrete gpu by default.

Hello, I am a newbie to Intel-nvidia-hybrid laptop. My issue is that I cannot use Nvidia dGPU for my favourite apps. I have tried Optimus Manager and Envycontrol but both of them breaks my system. I am using HP Envy laptop with Nvidia gtx 1650 ti maxq. Thank you!

Afaik the proper solution is to use https://github.com/Antynea/grub-btrfs/blob/master/initramfs/readme.md and/or rollback the root to a snapshot.

In fact I’m pretty knowledgeable around btrfs and snapshot-tools as well. :D I codevelop https://github.com/Antynea/grub-btrfs.

Something I noticed is that the instructions here before step 2 suggest that the files /etc/initcpio/install/grub-btrfs-overlayfs and /etc/initcpio/hooks/grub-btrfs-overlayfs might exist, and they don't for me. Worth noting that I installed through pacman, which may be a reason they don't exist if I'm reading those instructions correctly.

In Debian, I see that there is a custom installer "Spiral Linux" (https://spirallinux.github.io) with non-default settings that achieves the same kind of mechanism using "grub-btrfs" (https://github.com/Antynea/grub-btrfs) in combination with "snapper-rollback" (https://github.com/jrabinow/snapper-rollback) and a BTRFS subvolume layout suggested by the Arch wiki (https://wiki.archlinux.org/index.php/Snapper#Suggested_filesystem_layout).

grub-btrfs

When the issue first arrived (around 01/11/2023, IIRC), I did try posting an "Issue" on the GitHub page for grub-btrfs (located here), & more specifically on Issue #254, however, for whatever reason (at that time) I wasn't able to make a post on that Issue/forum.
