Should I enable secure boot after installation of Linux

I think you wrote it the other way around. Event if some vulnerabilities existed, wouldn’t it be easier to compromise a machine without secure boot?

Yup. I did do just that.

I'll fix it. thanks!
 


Has anybody been able to installed Mint 21.3 or 22 with secure boot enabled. ?

Me. I have Mint with Secure Boot enabled. It was painless. I've been using Secure Boot for quite a while - when and where I can. I did have to go into the computer's settings and select the bit about Mint, I think. That was a while ago so the exact steps are forgotten by now. I didn't think to take notes or anything like that as it wasn't really difficult.
 
Made an account to add my two cents on this. Even though Linux supports Secure Boot, not everything works well with it. I've had issues where when enabling it, I could no longer use the Unity Editor that was installed via Flatpak. On my girlfriends machine, it was causing issues with gaming where the game would work fine for about 40 minutes or so and then tank to 1 FPS. Disabling secure boot fixed both of these issues.

Hi there!

Just made an account too, and just to confirm this. Having issues with secure boot on with "amdgpu" module, wireless gamepad, returning from suspend, etc. Disabling secure boot solved the issues; tried with Fedora 41 and Ubuntu 22.04/24.04.

Best regards.
 
Never had any issue on Fedora, on three machines.

Those modules should be OK if they were signed. On that Fedora test:
  • did you install the modules from RPM Fusion?
  • if so, did you generate and enroll akmods' MOK and enable akmods automatic signing?
If you didn't do this the rpmfusion and akmods way, no wonder why: you should have signed those modules manually yourself, check this repo out (I used to manually sign modules a while ago on Fedora)
