IIRC when the system suspends all USB devices appear as if they are
unplugged, and then after resume they appear as if they are
replugged. When logind and X11 see that the display device goes away
they will remove the seat/die. That makes your session go away.

IIRC for USB storage the kernel got updated to work around this and keep
the block device around during suspend. Most likely this needs to be
done for USB display devices as well. So my guess is that this is a
kernel issue to fix.
