Package: ifplugd
Version: 0.26-2
Severity: normal
I am offline right now, so please excuse if this is a duplicate.
ifplugd doesn't play nice with X when it's monitoring an interface
that doesn't currently exist (e.g. USB). All X processes doing
graphics will stop every second for a brief moment, which can be
quite annoying.
To reproduce, run glxgears (or a .mpeg file in xine) and then start
/usr/sbin/ifplugd -i nosuchdevice -q -f -u0 -d10 -w -I -b -n
It would be nice if ifplugd could be a little less aggressive about
polling the interface.

Yes.

* ifplugd/args: -f -u0 -d10 -w -I -b
Why should it not happen with hotplug? What do you think is *not*
happening on my system that should?

Right, I can confirm that this seems to work. Have you considered
making this the default?
Anyway, we can close the bug, but consider making -M default for
hotplug interfaces, please. Or are there drawbacks?
