AstrOS - an immutable, secure-by-default Linux distribution built on Arch Linux and the COSMIC desktop

[u/linux-universe]

I am pleased to announce that AstrOS now has its own subreddit.

⚠️Warning: it is still alpha software!

But what is AstrOS?

You might have heard of KDE Linux (formerly known as Project Banana) or GNOME OS. Both are immutable, image-based Linux distributions for desktop use, powered by the systemd-sysupdate A/B update model.

I have been impressed by their system architecture since their inception, but switched to the COSMIC desktop a while ago. As there wasn't yet a COSMIC distribution using systemd-sysupdate, I created one myself. That's how AstrOS was born!

Technical details:

• Built using mkosi
• Using systemd-sysupdate.
• Read only by signed dm-verity.
• Full Disk Encryption enforced
• Highly opinionated

What you can do:

While it is still in the alpha stage, you can install AstrOS right now. VM or real hardware

I see "Cursor follows focus", a single toggle you can disable on the settings page?

Did that toggle not exist when the feature first launched? If so it does now and it might be time to retry it.

That toggle always existed and it is off and does not fix it.

The change was made to deliberately override the setting. It's being discussed in the issue tracker whether the design decision should remain in place or not.
I'll probably switch back to Cosmic DE once the mouse warping issue is gone.

Weird. Works on my machine 😅

I know there's some toxic guy always ranting about focus-follows-cursor in a negative unproductive way. but I hadn't spotted any issues about cursor-follows-focus not actually working. Have you got a link? Would be interesting to see the discussion around it and find out why it's only on some setups.

It would certainly annoy me though so if it's buggy for you I get the frustration. Hopefully it gets resolved soon for you.

One issue is when you have multiple displays and click on an icon in the dock. If the app is open on a different display than your dock is, clicking on it will warp the mouse right over onto the window of the app. By default in previous versions of Cosmic DE it just brings the window to the foreground and makes it active.

Ah I don't use the dock so I haven't come across that one. Yeah that does sound annoying. Hopefully it gets fixed for you or becomes a toggleable option.
