I also have this problem of occasional long delays with the remote. The
long delay logjam can usually be broken within a second or two by
keypresses on a wireless keyboard. After the keypresses break the logjam
the remote works fine for some unknown period of time. The system is not
running any screensaver. Both gnome-screensaver and xscreensaver have
been removed from the system.

The system is a separate frontend from the master backend and is running
the following version of myth.

[root at shuttle1 ~]# mythfrontend --version
Please include all output in bug reports.

The Nvidia card is a GeForce 7600 GX running 177.82 drivers with the
following relevant options in the Screen section.

        Option      "XvmcUsesTextures" "false"
        Option      "UseEvents" "True"

Multiple video driver versions have been tried with no change in
behavior. The configuration is not using opengl as the command line is:
  Exec=mythfrontend -v important -O ThemePainter=qt -l mythfrontend.log
at startup.

I have previously put in some additional verbose statements looking for
the lirc and everything seemed to be okay. Those statements have since
been removed.

Any other things to look at would be appreciated.
