I did run a similar test and there were no errors detected. Thanks anyway!

I can sudo. Last time I looked into this, Memtest86+ version 6 was required to work with UEFI but it wasn’t available for Ubuntu 22.04. Now it seems that 24.04 has it, so I might update and see if I can get the test running. Thanks for the suggestion!

I can’t run memtest unfortunately. The option isn’t there and I don’t have permission to boot from a USB stick.

I do have an interview scheduled, just saying…

It wouldn’t affect boot though.

I just did that! Brilliant idea, thanks!

That’s a good idea. If I can get it to boot today, I will check the logs, thanks!

It’s not hard to reproduce, but it’s annoying that when they finally came here to check it, no problems happened. I had to bug them so much to even get them to have a look.

It seems to me that installing external audio drivers and changing Pulseaudio configurations is messing with the OS. Mint uses fairly old, stable packages. Newer distros have Pipewire for audio now. It’s a Pulseaudio replacement and might be useful in your case. Have you tried a newer distro? You can try Ubuntu 22.04 or Fedora from a USB stick to see if your audio equipment works out of the box. Then you won’t have to fiddle so much with the OS. Fedora Silverblue in particular is immutable and you can reset the OS to any current or previous state with one command, even without Timeshift. Another thing for testing software like DaVinci Resolve is Distrobox containers. You can change whatever you want inside a container and try different distros but you won’t break the underlying OS. Hacker’s dream.

Even distros like Mint are buggy and requires multiple restart every day.

There is something wrong with your installation. Other people just restart to update the kernel often once a week/month. So you might as well tell us what’s making you restart Mint so often.

I can’t believe no one mentioned this yet. I hope OP reads this comment. The first step is to make sure this new computer you want to buy is compatible with Linux. Otherwise your experience will be very frustrating, no matter what distro you choose. That is, if you can install any distros at all. Ask the vendor if this machine is compatible with Linux.

This. No one would buy an arbitrary computer and expect MacOS to run on it, for example. Buy a computer with known Linux support. Ask the vendor.

Every popular sub on Reddit is the same four questions or topics posted over and over again. It is like users are unable to read any previous posts. I’ve seen old time users writing basically the same comment on multiple posts for years, and then new people would come and ask the same bloody question again. This convinced me to never post anything of value on Reddit. It just drowns in a sea of comments and will never be read again.
