OK, I guess that's the other sensible explanation; I just didn't think of it (somewhere I still remember my first peeks and pokes ;) ) >Not necessarily.

I have no idea what points are, but I have a problem with the idea of turning on or off the umptieth of a pixel :) >> So what happens when you use a regular (say 1080p) external in combination >> with a Retina display, and for good measure you deactivate "screens have >> separate spaces" to get the traditional >> spaces-span-all-screens-of-the-desktop behaviour? > >You'd have one 1920x180 display at 1x and another display at 2x. As you drag >(non X11) windows between them, they'll adjust their scale factors. I trust Apple to make that work even if you leave the window spanning multiple screens, but the question was about XQuartz.

True, and the value obtained from the hardware was rarely reliable either (in my experience at least). >RandR doesn't really have anything to do with modelines. And thanks for that >shuttering and horrific set of memories that you just conjured up by just >mentioning modelines... LOL, you're welcome and goodmorning :) I don't know about XQuartz, but I've had to figure out the modelines issue when adding new modes to the list on my Linux systems (xrandr --newmode "1366x768" 85.25 1366 1440 1576 1784 768 771 781 798 -hsync +vsync). >You can use xrandr from the command line to put XQuartz into fullscreen mode >at the native display pixel resolution (eg: `xrandr -s 2880x1800`), That's probably a good enough workaround for the OP for now. >but that will be a fullscreen mode and will render your windows much smaller >than what you want. How so? If you want 100x100 px and you get 100x100px you got what you asked for ;) Afterwards you just have to change your configuration, starting with Xft.dpi, and the window sizes you request. Not a problem as far as I can see, as long as you don't try to use those same settings on a regular display (and you don't depend on bitmap fonts only available for lower resolutions) ... Mostly unrelated: do you happen to know if anyone has considered or discussed bringing Wayland to the Mac? R _______________________________________________ Do not post admin requests to the list.
