[mythtv-users] Using IR Remotes without LIRC

Fri Sep 26 02:29:19 UTC 2014

I wonder if the restart of X is a bug in X or if its designed to work that
way...

It reminds me of how the design of OpenWRT and its ability to apply all
changes except modifying the switch vlan settings.. only upon reboot...ugh.

Definitely less than 2 cents but i couldnt help but think that this may not
be the way X is supposed to work.  I'll attempt to figure that out, and
file an xorg bug report if i cant find documentation detailing this aspect
anywhere.
