When trying to run a separate Xorg, at first it failed with no access to some tty, and then (with sudo) brought down my existing Xorg. :-D But when I rebooted, Xfce suddenly started working without extra help. I've tried several dozens of times and couldn't reproduce the problem in it. All I can add about that is two things: 1. It has some broken handling of scaling. When set to 1, most things (but not all, e.g. not the titlebar buttons, I think) have the same size as I have in GNOME at 2x scaling. And when I set scaling to 2, everything becomes tiny. 2. Emacs starts up faster than under WindowMaker or E, but still a little slower than under GNOME. The startup looks a little different, too: if you have some of my older videos saved, you can see it blinking with the scrollbar. Under Xfce, OTOH, I can't see that blinking, and overall the startup looks something like additionally buffered: less jittery, but a tiny bit slower as a result. Whatever the reasons is, it could affect later frame flipping as well. https://a.uguu.se/jzgYlBHd.mp4
