If anyone is still struggling with display resolution (tiny font) on Linux, here is what i did on my Linux Mint 19 (i switched to Mint).

Open control center, click on Appearance, go to Fonts tab, make sure Subpixel smoothing (LCDs) is selected and click on the Details button.

Under Resolution, turn off Automatic Detection, then change the Dots per inch (DPI) value to 120 (works pretty well in my case, fine tune the value according to your need).

Make the following changes if you use Firefox.

Open Firefox, then type about:config in the address bar and hit enter, click on I accept the risk, on the next page, search for layout.css.devPixelsPerPx and modify the value to 1.3.
