Introduction
XQuartz doesn't support HiDPI in any reasonable way, but you can sort of make it work on a temporary basis.
Instructions
Assuming you want to run a remote X application, and you want that application to use HiDPI
- install XQuartz
- for example
brew cask install xquartz
.
- for example
- enable full screen mode in XQuartz
- it doesn't work in non-root window mode.
- ssh -Snone -X z800.local
-Snone
is important because session multiplexing doesn't work very well with X forwarding.
- run
xterm
- we need an X (non-native) terminal for later.
- in a native terminal (Terminal.app) run
xrandr --output default --mode 5120x2880 --dpi 218
- unfortunately we can't make this permanent, after this, you will be in high resolution full screen X, with a very tiny xterm.
- run whatever application from that xterm
- you might need to force HiDPI mode for that application, but it should have all the pixels available.
- to get out of X, press CMD+Opt+A
- unfortunately this turns off the X resolution.
- to get back into X at the correct resolution, run
xrandr --output default --mode 5120x2880 --dpi 218
again in the native terminal.
It's awful, but it works.
