There is an issue still in 133, where when you plug a USB keyboard or mouse,
while logged in as non-root, the device will not be usable by Xorg any more
(since Xorg changes effective UID to the logged in user, not root)
The Belkin USB KVM (at least my one) essentially "unplugs" the keyboard & mouse
when switching away from a machine, and then plugs it in again when switching to
a machine.
The problem is that the ownership of the device isn't always changed to the user
currently logged in, and as such when Xorg tries to use it, and load a streams
module on it, it still fails.
I've worked around this issue - by having a loop like:
while true
do
chown myuser:mygroup /dev/usb/hid*
done
running when plugging in the keyboard.
Of course I only run this for short times, since it chews the CPU, but to do
otherwise won't guarantee the ownership change - since Xorg might reach quicker
than I can change it.
The bug is:
