I suspect that the Pocket-Reform screen output is scaled by a factor of 2. This improves readability. On the other hand, I keep finding that some programs can’t handle this. The “Settings” windows, in particular, are so cluttered that you can’t reach all the menu items—let alone the OK button. This makes making changes a game of chance.
Long story short: is it possible to permanently change the scaling factor?
And if so, can you use any factor (e.g., 1.3), or is it best to use whole numbers?
I don’t own a Pocket, so I don’t know the detailed setup it is using, but if you are running sway, then yes, you can change the scaling factor permanently in ~/.config/sway/config
The syntax is as simple as
output <name> scale <factor>
Since I don’t know the Pocket’s setup, I don’t know how the display is connected. You can, however, get a list of all connected displays by running swaymsg -t get_outputs
in a terminal.
You can also test different scale factors without changing the config, again by using swaymsg: swaymsg output <name> scale <factor>
I have never tried fractional scaling for more than a brief attempt, since it didn’t look too good on my screen. It does work however, and the only advice I can give is to just try how different values look on your hardware.
If you are running Gnome, then I am sorry, I don’t know how it works there.
