Xephyr DPI setting

[Botspot]

Hello, I maintain a somewhat similar repository to yours. It's used to boot linux filesystem images , with systemd-nspawn, and displays the desktop using Xephyr.

So it's like a virtual machine, but much faster than one because it doesn't emulate anything.

I have devised my own hacky clipboard-syncing script for it. (uses xclip) It looks like your clipboard-syncing script may be better, as mine has serious issues.

I noticed you said you were having font scaling issues in Xephyr. I did too, for a long time. Then one day I accidentally discovered that Xephyr has a dpi setting!

So now I use this Xephyr command-line:

Xephyr -dpi 96

I thought you might find that little tip helpful.
