Screen power management is not disabled during video playback in XBMC
Note: I am using the term screensaver here. As far as I can tell Ubuntu no longer has anything called a screensaver. I am using the term for when the screen goes black but is still on (a slight bit of backlight can still be seen). This usually precedes the screen actually going to sleep.
Since upgrading from 12.04 to 12.10, when I play a video in XBMC the screensaver will kick in and blank the screen during playback. Sometimes the screen goes black just for about half a second and then comes back, sometimes it stays off until I move the mouse. This did not happen in 12.04.
$ lsb_release -rd
Description: Ubuntu 12.10
$ apt-cache policy xbmc
What I expected to happen: During playback of video the screensaver and power management for the screen would be disabled.
What happened instead: During playback of video the screen went blank, sometimes for a short time, sometimes until moving the mouse.
