Hi from desktop mode!

I use a Arch Linux install (configured to have a 'as close as possible to SteamOS 3' experience, so I still have the usual gaming mode and desktop mode) and I use desktop mode for web browsing, programming (and related stuff), system maintenance and installing stuff.

I use Gaming Mode for gaming, ofc.

No problem.
