I used Unity Tweak Tool in Ubuntu 16.04. Iā€™m running now a test environment where 16.04 was upgraded to Ubuntu 18.04 LTS. I just checked and Unity Tweak Tool is still there and scaling my High DPI screens properly. The settings Iā€™m using for scaling on a 1920x1080 monitor are:

The Text scaling factor scales both fonts and UI elements like title bars, buttons, etc.

Icon size is preset but the text size under it increases giving the illusion the icon size changed:


In the .gif above scaling starts at 1.38 on a 1920x1080 monitor. Then it is changed to 1 and everything gets tiny, which is normal. Then it is changed to 2 which is ideal for the visually challenged. Once again the icons have fixed pixel size and the font shrinking or expanding under the icon gives the illusion their size is changing.

To install Unity Tweak Tool use:

sudo apt install unity-tweak-tool
