I am running 18.04 LTS with two monitors: a 24" 1920x1200 one and a 27" 3840x2160 one.
The text on the high-resolution monitor is too small to read.
I tried using the "Screen Display" setting screen to change the scaling to 200%, but it just makes everything HUGE and blurry. I have no idea why they have chosen only multiples of 100% as available options, but this type of UI scaling isn't what I'm after. I want to use the monitors at native resolutions, except with relatively larger font size on the high-res monitor so that it's readable. The rest of the UI should remain the same size.
The scaling option mentioned above scales both monitors at the same time, even though controls are shown separately for each monitor. Changing one automatically changes the other. Seems like a bug. There are posts and answers for custom scaling for each monitor using
xrandr, but again, that's scaling the whole UI. That's not what I'm after.
Can I get monitor-specific font scaling options in Ubuntu like in Windows 10?
I would also love to have dpi-aware mouse movement between screens as enabled by https://github.com/mgth/LittleBigMouse on Windows.
