Is there an app to change the scaling of an entire Linux system?

Question

linux

I have Elementary OS 6 Odin on a laptop with a screen resolution of 1920*1080. After working in Windows, the small application interface in Linux causes some discomfort (the browser interface, for example, is 20-25 percent less than Windows). Yes, I read that everything can be fixed by modifying the configuration files, but, firstly, it didn’t work for me, and secondly, I’m still an amateur in using this system, there are already enough problems, so I would like to solve the most pressing of them in a quick and simple way that is understandable to a beginner.
On Windows, when first setting up the system to fix application scaling, I modify the registry values:
1. DpiScalingVer 0x00001000 -> 0x00001018 (REG_DWORD)
2. Win8DpiScaling 0x00000000 -> 0x00000001 (REG_DWORD)
3. + LogPixels 0x00000078 (REG_DWORD)

Answer 1

Set DPI to approximately 156 and scale
For Xwindow, everything is simple, through xrandr
xrandr --output eDP-1 --dpi 156 --scale 0.95x0.95
eDP-1 - display name from xrandr -q
