I use KDE. Some use GNOME. Most other options are probably to be left out as X11 is unsafe.
Cosmic is not nearly finished, but will probably be a bit safer, as its in rust, even though not tested.
Then there are window managers like Sway, Hyprland, waymonad, wayfire, etc.
RaspberryPi also has their own Wayland Desktop.
Is every Wayland Desktop / WM equally safe, what are other variables here like language, features, control over permissions, etc?
That leaves the desktop running in a parallel session
I think you missed the point. Switch the tty to realize your de is irrelevant in regards to security, because you don’t even need one…
Wait until you want to watch a video, look at a photo, play a game or view a PDF lol
You can do all these things on a framebuffer. Ok, maybe the game thing is a bit of a hassle, but the other stuff is totally doable.
What the duck has this to do with anything.
The entire point is that your DE has NO security features at all, those come ALL from the underlying system such as PAM for example, managing the authentication and such.
These stupid strawmans “huhr dur watch a video”
Besides that I’ll just answer the straw man argument anyway because it’s even stupid if you take it seriously YES YOU CAN ACTUALLY LAUNCH GUI (such as a game) DIRECTLY FROM TTY.
And I quote
Learned something, thanks
a DE gives no security features that give your system additional security, yes. indeed, a running DE makesbyour system less secure, in some sense. but exactly here you can have less and more secure DEs, and some DEs have security features that make the DE itself more secure than other DEs.
