In both client config and forgejo config? And docker config?

It’s working for me, but I had to add a config to my ~/.ssh/config file

For Bazzite , I search for “how to do X in Silverblue”, or “how to do X in KDE”

Bazzite is built on the same technologies as Fedora Silverblue (immutable base, ostree, btrfs etc).

You probably already know this, but just to be clear; Timeshift (by default) only backs up your system, but not your data, documents photos etc . Basically everything outside your Home directory.

You can probably tell Timeshift to also backup your home directory, or install a separate backup app for that.

Any idea where these hundreds of unused Docker volumes came from?

Yes, this happens automatically for me when I launch games. I don’t remember doing anything special to set it up (Kubuntu with nVidia drivers on X11). I do mostly game in true full screen though, not “full screened window”
