Migrated to Debian 11 from Ubuntu 6 months ago. Loving it.
With Ubuntu I used to stick to the LTS releases and wait for a .1 upgrade. But I’ve been running a Debian 12 VM in anger (ie actually doing work on it - I needed PHP 8) for the last month or two and it’s been faultless for me. Might break the habit and upgrade the main machine early :)
Edit: almost pulled the trigger a little early tonight. Ironically the one package I have that doesn’t seem to exist for 12 yet is Virtualbox - not something I could install & test in my Debian 12 VM…
As the manual says you should run
apt list '?narrow(?installed, ?not(?origin(Debian)))'
before upgrading to check what non-Debian packages you have installed.
I’ve never understood why there’s a fuss about default wallpaper. It ships with a dozen options and you can obviously install your own. I guess it’s the opportunity for a news story and a sign that things have reached a certain level of development and are getting close to release.
Personally, I saw the item on installing your own dynamic wallpaper at https://www.omglinux.com/dynamic-wallpapers-for-gnome-desktop/, followed the instructions on github and set up a lovely time-of-day based wallpaper based on the game Firewatch (https://github.com/manishprivet/dynamic-gnome-wallpapers#code-firewatch) - I love all the sunrise/sunset options there but if you’ve played Firewatch then this one might speak to you :)
