Thanks, it would be worth reporting upstream even if you don't have the
debug cycles to investigate

Title:
Xephyr Input is broken
Status in xorg-server package in Ubuntu:
New
Bug description:
I'm using Xephyr for a multiseat system (4 GPUs -> up to 12 screens;
using VirtualGL for 3D acceleration.)
The eventual command line that LightDM ends up running is:
Xephyr -fullscreen :0 -seat seat5 -auth /var/run/lightdm/root/:0
-nolisten tcp
In 18.04 and earlier this works great.
Important note: There is a strong chance my system had the version of
Xephyr from the Multiseat PPA with Evdev support patches
(https://launchpad.net/~ubuntu-
multiseat/+archive/ubuntu/xephyr/+packages).
In 19.04 I get:
root@redstone-server:~# DISPLAY=:200.1 Xephyr -fullscreen -seat seat6 :20

The display is correct, but no user input (mouse or keyboard) works.
It looks like Xephyr can't find any input drivers. I also tried
specifying drivers (eg Evdev, libinput, keyboard, mouse, ...) Nothing
worked.
Extracting the version of Xephyr from https://launchpad.net/~ubuntu-
multiseat/+archive/ubuntu/xephyr/+packages runs correctly.
