If I were to speculate, they are waiting for the NVK (Open source NVIDIA driver) to be more mature. So, they wouldn’t have to release two versions and wouldn’t depend on NVIDIA to update their driver to work with software the Steam Deck uses. I.E. Steam Deck uses gamescope for everything outside of Desktop mode. NVIDIA’s driver didn’t work with it until 2 months after the Steam Deck release. Even though it had existed for years prior.

I just use the Firefox flatpak from flathub.

Definitely a strange choice for a distro that pushes flatpak to not use it for the browser by default.

See https://wiki.winehq.org/FAQ#How_good_is_Wine_at_sandboxing_Windows_apps.3F from their FAQ

Are you referring to the ones with excessive sandbox permissions that flathub allows by default? Or is this something else?

Do you have a work profile or multiple user profiles set up on your device? This is similar to another issues they had a couple months ago, where my phone would fail to boot even into recovery to try to factory reset it.

Since drivers are so specifc, people’s anecdotal experiences with having to install them is never going to be shared.

IE, I had to install a wired NIC driver just last month on a fresh Windows 10 22H2 for a Dell laptop that was no more than a few years old.
