I want to use Manjaro Gnome on a 5 Inch touchscreen. The OS is very good to use for touchscreens. But there are a few issues with a 5 Inch touchscreen.
The Appicons in the Appoverview are to small and the Appname is not readable
800x480 in landscape mode is definitely not supported by GNOME; even if the app launcher worked, you’d have a lot of problems using applications with that resolution.
When I use the global searching the App and other results are on a very nice size. I wonder why the Appicons are so small in the App overview.
You are right the most Apps are overlap the screen. But A few of gnome Apps like Weather, Contacts are looking very good on every position on this screen.
Its ok for me when not all Apps are working. But it would be cool when the standard functionality works.
Yes, Phosh is designed for smaller screens like yours. It was originally for Purism phones, but is now used in a variety of cases. I haven’t installed it, but it should be easy.
