• How to use Angelfish as touch-friendly web browser in Steam Deck’s Game Mode – My Little Blog

  For whatever reason Steam Deck pretty much has two default browsers: Google Chrome in Game Mode and Firefox in Plasma aka. Desktop Mode. Firefox is absolutely unusable in Game Mode. Chrome (probably most other Chromium variants as well, I’ve only tried a handful) work okay-ish – at least they don’t go ballistic on touch events but they are not a truly nice experience either.

  Readers of Planet KDE probably already know that some KDE applications have convergent GUIs thanks to Plasma Mobile, including the Angelfish web browser. It took some fiddling but after a while I managed to get it into a shape that’s very usable in Game Mode. Without any tweaks Angelfish defaults to use its desktop GUI and thereby runs just fine in Plasma Desktop, perhaps docked to a monitor.
