thanks to Shinkamui on Telegram, I decided to post this guide about Apps scaling.
The display of our JingPad A1 is a 11 inch Amoled with a resolution of 2368*1728 (266 ppi), so UI of Apps not scaled will be really small to be properly use on our tablet.
So, first of all, try to find the apps you need to scale, eg:
Or using Terminal:
Identify the app and open it using Gedit or another text editor:
You have to find the “exec” line, in my case for Clementine the original string was:
exec= clementine %U
It’s a QT Application, so I decided to edited as follow in order to get a 2x scale (zoom):
exec=QT_SCALE_FACTOR=2 clementine %U
In case It was a GTK App (Clementine is not, but just in case…), the scaling code is different:
exec=GDK_DPI_SCALE=1.5 GDK_SCALE=1 appname
See the difference between the original UI scale factor and the 2x…
Scale factor 2x:
Another example, Krita scale factor x1.4:
As you can see, UI Scale matters.
Maybe in the next updates JingOS could automatically implement the SCALE FACTOR in every app launched by user, we don’t know…
