Did a search for ubuntu “integrity: problem loading x.509 certificate” and the first result indicates out of date bios certificates needed for secure boot on older laptops. Disabling secure boot seems to be the suggested fix.
You might check your BIOS clock time too, if the certs are ‘expired’, it might be the future, or more likely, the past. Certs have validity timers that specify start and end.
It’s more likely that your BIOS is just old, and you’ll have to keep secure boot disabled from now on.
Kernel boot logs aren’t well disciplined to be careful about what is an error or not. Sometimes it’s just checking for the existence of hardware and reports the error it gets if it doesn’t exist.
Arch based distros are easy AF. I’ve been on Linux for 2 years, I’ve tried 10+ distros, and Arch has been the easiest for me, and stable as it gets, while allowing me to get the latest drivers needed for gaming.
I’ve been using Crystal Linux, but got tired of it’s CLI only package helper, and since then I’ve moved to Manjaro KDE.
Whatever you chose, make sure you get automatic BTRFS snapshots, so you can roll back at boot whenever you wreck it.
I’ve read here on Lemmy that NixOS is a great concept but the execution leaves a lot to be desired, stating that it’s overly complicated and documentation is lacking.
If you only care about stability then you should go with Debian. If instead you want something that limits you so that you can’t easily wreck it, you could use an immutable distro like Vanilla OS, Fedora Silverblue, BlendOS or Ubuntu Core Desktop.
well, I’m not sure traditional is the right word, multiseat has been used for a very long time. It used to be a bit better supported. The issue is that since the migration to wayland, it has become… a lot less supported. It is still possible, but most of the guides are x11 guides for a reason.
EDIT: I should say I hope seatd at some point could support multiseat but at the current time I don’t think it has any facilities to, systemd-logind / elogind do support multiseat, but I dont currently use them
