One of the challenges of running Linux on a phone is finding apps which are suited to the small, typically portrait, screen.
Mobian has a
scale-to-fit system, which can be enabled on an app-by-app basis.
There is a global tweak:
gsettings set sm.puri.phoc scale-to-fit true
And this works pretty well.
(Blogging to keep a note of it for future.)
“Pretty well” is not the same as “perfect”. There’s no doubt that this is a hack, and a more targeted approach is likely to be better overall. Ideally, this would be software designed to adapt to the screen resolution, or per-app scaling.
Thankfully, there is the excellent LinPhoneApps, and LinMob has a great guide to targeted scaling.
