How to setup hidpi for linux?

Question

linux

Good day!
I tried to switch to Linux more than once (LMDE 3 Cinnamon || LMDE2 Mate), but the stumbling block is always the screen resolution for me ...
For clarity, the screen resolution is 1920 x 1080 px Scaling 120% (Win 10) and so comfortable to work with. I just can not find a suitable version of Linux with hidpi support. The fact is that all working environments, except for KDE, do not support 110-190% scaling. You can choose only 100% or 200% (double). And the KDE desktop environment is somehow not very pleasant compared to Cinnamon or Mate. And judging by the forums, there is no way to configure other working environments with the desired scale. Accordingly, I would like to hear your possible solutions to this problem.
PS I'm still not touching on the fact that some programs run through Wine, even in KDE, with the right scaling, also remain in small font.
What do you advise?

Answer 1

I have added the permissions I want and switch if necessary.
those. if you sit next to the monitor, then I do more 1920x810
if far from the monitor, lying on the couch and you need a larger font, then smaller 1680x720
then the question was What to choose a non-standard resolution for an Ultra Wide 2560x1080 monitor?
the old video card does not export
, calculate what you need for your card

add code to autoload : this is mine for example

#!/bin/bash

xrandr --newmode "1920x810_75.00"  162.75  1920 2040 2240 2560  810 813 823 848 -hsync +vsync
xrandr --newmode "1800x760_75.00"  142.75  1800 1912 2096 2392  760 763 773 796 -hsync +vsync
xrandr --newmode "1680x720_75.00"  125.75  1680 1776 1952 2224  720 723 733 755 -hsync +vsync

xrandr --addmode HDMI-0 1920x810_75.00
xrandr --addmode HDMI-0 1800x760_75.00
xrandr --addmode HDMI-0 1680x720_75.00

#xrandr --output HDMI-0 --mode 1920x810_75.00
xrandr --output HDMI-0 --mode 1800x760_75.00
#xrandr --output HDMI-0 --mode 1680x720_75.00
