MythTV DPMS Not functioning correctly after upgrade to xorg-x11 7.1

[anonymous]

I am running a Gentoo box currently with 2.6.18-r1 kernel on two Pentium4 systems with NVidia video cards. This same issue is present on both machines. I am using nvidia-drivers (latest version). DPMS was working perfectly until I upgraded to xorg-x11 7.1. I have have tracked the status of dpms thru use of 'xset -q' and it inicates DPMS is enabled when appropriate, and disabled when appropriate. When I bring the machine up without Mythfrontend running, DPMS engages automatically and works repeatedly as expected. After I bring Mythfrontend up and view live tv or a recording, then exiting, DPMS is disabled and re-enabled appropriately according to 'xset -q', however the monitor never turns off. I can type 'xset dpms force off', and the monitor immediately shuts off, or I can reset the dpms settings by 'xset dpms 0 0 600', and DPMS again works normally, shutting monitor off after 10 minutes. It appears that when Mythfrontend is bringing DPMS back to an active mode, it is either failing to restart a clock, or the settings are corrupted (non-visibly).

Sorry, if the ticket created any confusion. I just reread it, and found I left off some of the more important information! The description tends to lead the reader towards an X11 bug, however, without running Mythfrontend, DPMS works perfectly. DPMS breaks only after MythTV is used to watch live-tv, and then returned to the menu (DPMS Disabled, and then Enabled via Mythfrontend).

I also have this problem. It seems that this problem is not unique to MythTV. According to a user in this thread, mplayer also has this problem.

For me this problem occurs when updating from xorg-server 1.0.2-r7 to 1.1.1-r1 (which is a dependency of xorg-x11-7.1). Downgrading to 1.0.2-r7 solves the problem for me.
