Secureboot isn't worth the 1's and 0's it's made of. It's the illusion of security, since it was already defeated. It only inhibits incompetent hackers and malware. The weakest link in all computer security is always the user. SB just causes more problems than solutions.

this is really stupid advice. Secureboot should be installed on laptop otherwise your device is as good as open. Sure it has some CVEs but its a big step up in security and its getting better and better on linux.
This performance issue is likely due to an issue with the driver not with secure boot itself. Maybe since it is an old driver it wasnt signed.
I second SavvyWolf. Full disk encryption is better than SecureBoot. SB is security theater for people who don't know what they're doing and don't know how to avoid getting their laptop infected in the first place. As I said before, SB has already been defeated. Every hacker/malware can bypass it already. It's like pretending you have armor on and going headlong into a sword fight.
What advantage does secure boot have compared to full disk encryption? The only examples I've seen have been contrived evil maid attack that fails under scrutiny.
If you have to choose between one, then yes; full disk encryption is superior. But they should ideally be used in tandem.
Without secure boot, you are vulnerable to evil maid attacks. A bad actor can modify your bootloader (which has to remain unencrypted) in a way that allows them to steal your encryption keys. Secure Boot prevents running unsigned bootloaders, which negates this risk.
If someone has access to your device enough to modify your bootloader they could also just install a hardware keylogger or hidden camera and get your password that way.
Sure, but that's much harder to do undetected. Don't let perfect be the enemy of good. Secure Boot still prevents against particular types attacks.
I get that perfect is the enemy of good, but you also need to have defined threat models. Secure boot protects against people covertly taking your ssd, putting it in their own device, overwriting the OS with one that looks identical but is a key logger, and then putting it back in your system. Yet systems with secure boot have no tooling to stop attackers from just... Putting a hardware keylogger inline with the keyboard.
It is not my intention to question or insult your intelligence, only to offer a stupid solution as it’s happened before.
Is your monitor connected to the video card and not accidentally the motherboard?
It is connected to the graphics card. Like I said, it ran fine on Windows so its not a hardware issue.
Secure Boot can sometimes mess with it. Try disabling that in your BIOS.
This seems to have fixed it! Thank you!
The most current NVidia driver generation needs special setup for secure boot. But IIRC it doesn't support the non RTX cards anymore. And sadly I can't remember how to set up the older generations.
For the newest you need a setup that compiles and signs the Kernel module of the driver and you also need to manually import the (generated) key into your UEFI to allow secure boot to succeed. The former is usually mostly automated by your distribution, but the latter need to be done by you manually.
Or, just disable the increasingly inaccurately-named "Secure Boot."
Yeah, that's always an option. If you want to. On paper I like the idea for security reasons, but I dislike that a single company can basically control, what is able to be installed/executed and what is not allowed.
It's always something-something-Microsoft
Check to make sure you are using the 'recommended' video driver for your system according to the driver manager. Also, check to make sure that you have installed all available updates through the updates manager.
It sounds like you are using Steam, so I would recommend using the install directly from the official site instead of the flatpak, if that's what you've done.
I'm sorry I can't really help in any meaningful way except to say I had the exact same terrible issues. I got an AMD card instead and all the problems are gone.
I haven't used NVIDIA for years so I'm not much help with that, but have you tried using the Proton version of Portal? It usually works better than the native version.
Unfortunately its not just Portal thats the issue. Its everything.
Have you tried the proton version of everything?
I have for some, and had the same issues, but its solved now. Apparently secureboot messes with the GPU drivers or something. I turned that off and its working fine now.
Just a guess, you're not done the MOK, that's kind of keys used to sign modules that are stored somewhere deep in the hardware. Without them your laptop refused to load the proper modules and you was using shitty nouvea driver, so the bad performance.
I'm pretty sure the newer nvidia driver dropped support for the 1050. but I'm not sure which driver version was the last to support the 1050. whichever it is though, you will probably need to get that one.
