<s>Honestly can’t tell if this is sarcasm.</s> This is probably sarcasm.
If it’s not, you’re welcome to actually point out the configuration files I need to edit. I tried many “solutions”, even edited boot parameters to no avail. According to sources I read, someone without an Nvidia graphics card might have an easier time.
Play with the scale numbers and the resolution until you get the desired effect. Can't give a full tutorial here but "xrandr hdpi" should yield helpful search results.
I'm not denying it's a pain and Windows/MacOS are miles ahead, but this is how you can get by on Linux with X. I use it daily for work and media, on a variety of monitors.
Thanks for the info, will try this when I get around to it. But this sounds like scaling a low res image to fit the pixels instead of native HiDPI support, is that right? Then it will probably be blurry?
Edit: Maybe you meant using a native 2x scale paired with downscaling. Interesting, sounds promising.
1) Learning nano/vim
2) Understanding what X window manager is and does
3) Understanding how config files work
4) Editing the appropriate config file to change DPI. Be careful not to do something wrong or you'll mess your system up
So easy my grandma could do it.
