Manjaro is great.

I use paperwm on Wayland gnome. If you like a scroll wm, is extremely easy to find out by installing the extension. It’s one click away. It might not be for everybody and has a few glitches, but fits my workflow better than other paradigms.

It tried out niri and found it identical to paperwm in most aspects. However, I like gnome and its features, so I missed those in niri. On the other hand niri didn’t bring me anything new. It is also difficult to install and configure and requires manual recompiling. I’ll certainly revisit it in a more advanced stage, should it reach such, but for now I’m perfectly fine with paperwm.

I am a paperwm user and I look forward to give this a try!

I use language tool for that in libre. Works great!

That’s a 404 …

I think, I can install keys in my AMI bios. So, basically, I’d create some keys, sign the kernel with it, reboot, install them keys in UEFI, enable secure boot, and, fingers crossed, I’d boot?

Stable just means no major version jumps in software that might break your current setup. That’s important for operating servers, not desktops.

I use debian Sid (unstable) at work and never had problems. Most of the time I get updates prior to other distributions I am using.

At home I use arch (derivates, manjaro), with great success.

I would abstain from Ubuntu. There, I had problems, it is very opinionated and not in s good way.

In a general sense I would always chose a distribution that isn’t too locked in to a certain desktop environment and provides updates, quickly.
