Rebuild an aur package against python 3.8

I've installed optimus-manager and followed the instructions. However the daemon isn't starting. I searched repo issues and I found that a recent python update caused the problem the advised solution is to rebuild the package against python 3.8. However I have no experience in doing that before. I can't find a good resource to follow to do so.

Also should I use optimus-manager or optimus-manager-git ?

I think its just a case of removing the package and installing it again via pamac (or an AUR helper if you're using one).

When you install it again it'll check for dependencies and should pick up on the new Python version. For the sake of simplicity, in general I think it's better to stick with the AUR version and avoid the git, it just makes it easier to keep track of things and if the version is the same I don't see what benefit there would be to building from source.

Edit, I've just checked and optimus manager is in the official repo so you don't even need to use AUR. They all seem to be the same version. Looking at the python issue it seems it was filed on the 11th of November and optimus manager was updated on the 15th. Did you install before or after the Python update?

I installed it from two days using pacman. I followed this guide Guide: Install and configure optimus-manager for hybrid GPU setups (Intel/NVIDIA) and the repos guide.

I followed the guide and rebooted expecting to find optimus-manager daemon active but it is not and here is the output of the sysctl status


I tried uninstall and install and same happened

Okay, have you tried installing the version from the official repository instead. Also when you're posting terminal outputs copy and paste them and then highlight it and click the icon that looks like this </> and it will format it nicely so we can read it more easily.

I'm afraid I don't have an optimus laptop laying around that I can trial and error this with, but for everybody else, could you also post the output of inxi -Fxxxza --no-host so we can see what kind of system you're working with. As a general rule its best to post this at the start when you're asking for help.

may you check if bumblebee is still active ? if so you have to disable it before activating optimus.

Here is the formatted output for sysctl status optimus-manager.service

Yes I have disabled it before reboot and the output for sysctl status bumblebeed.service is

● bumblebeed.service - Bumblebee C Daemon
   Loaded: loaded (/usr/lib/systemd/system/bumblebeed.service; disabled; vendor preset: disabled)

Looks like you need to rebuild the package:
trizen -S optimus-manager-git.

I have uninstalled pacman downloaded version and followed installation process for building aur package and it worked.

  1. cloned repo
  2. makepkg -sri

Great. In that case, mark the above post as the solution. Thanks :slight_smile:
