After some random time measured in hours/days, those two seats "lose" the input devices. They become non-responsive. The LEDs on the hardware light up so I know the mice and keyboards are awake and sending signals, but the X session itself does not respond. There is nothing interesting in the log files. the one seat with wired devices is fine. If I kill that X client and let kdm restart it, it will work fine for a while. What information can I provide to help diagnose this?you've disabled hotplugging, so if the device disappears at the kernel level at any point in time, it will not come back until you've restarted the server (VT switch should do too, btw). that is my suspicion here though that should usually print read errors to the logs. there isn't really much you can do about this, the old device model doesn't really lend itself for hotplugging.By hotplugging you mean setting Option "AutoAddDevices" "true"? If I do that, every input device gets assigned to every seat, so that keyboard attached to seat 1 also shows up on seats 2 and 3, and every mouse moves every cursor. Is there any way to limit the pool of "AutoAddDevices" so that it works correctly with multi-seat?1.12 has the ID_SEAT support, so if you set that property through udev the server only adds the matching ones. You'd have to then start the X server with -seat, see the commit message to 159b03e13760920274b573a2bccdbf6a79f059e7 for some detail.
Awesome! I'll look into it when I get the chance.That sounds like the solution I need. Let me read up on it and I may come back with more Qs. :-)
