Slow login on Ubuntu 22.04 with Nvidia GPU

I am getting slow logins (5+ seconds) on my Ubuntu 22.04. All related threads on this site point to Nvidia drivers as the main suspect. I looked into /var/log/gpu-manager-switch.log and got this:

Something is clearly wrong with Nvidia! but what is it and how to fix it?

I have already switched between several drivers with no positive result.

Nvidia drivers aren't being loaded and you're running with the iGPU AMD. Unless you're dual-booting with **Windows 11** you can disable Secure Boot in UEFI. That should be enough, assuming you have the correct Nvidia drivers already installed. Then, if you want to run with the Nvidia graphics instead just open Nvidia X Server Settings, select the "high performance" profile and reboot.

Thanks for the answer @ChanganAuto . disabling secure boot solved it.

@ChanganAuto, any solution for Ubuntu installed in Legacy with no secure boot?

@ManOnTheMoon You can't have a functional dual-boot with Windows 11 if you install Ubuntu in Legacy mode. And doing that is simply put ridiculous more than a decade after UEFI mode has become the norm for any preinstalled Windows. Very soon it won't even be an option in the firmware and not a second too late. Now, a standalone Ubuntu in Legacy mode should not have any issue with unsigned drivers therefore your question is nonsensical.

@ChanganAuto, thank you for reply. it's standalone Ubuntu in Legacy mode, wasn't by choice that it was installed in Legacy mode (Acer limitation). I've tried several solutions from the forum and only managed to fixed it with the installation of CUDA. Cheers

As ChanganAuto pointed out in the comments, the problem was caused by secure boot. disabling secure boot enabled the Nvidia drivers to be loaded.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
