Hello! I'm having the issue of my secondary monitor turning off and not turning back on. Using X+openbox, ATI 4870, catalyst(ati official) drivers, and xinerama (the ati implimentation, not the X only version) for multi-monitor support.
Both monitors turn off after 10 minutes, as they should with my power saving profile, but the second one doesn't come back on without a complete restart of X. And that poses a secondary problem of X not restarting properly. Whenever I switch out of a state that the 2nd monitor won't turn back on, I would be forced to go into a terminal and kill X, and then restart the machine. X would -not- restart properly without a reboot and would actually freeze all input without displaying X.
What would cause this and how can I fix it, without giving up the official ATI drivers?
edit: Solved. According to their latest driver documentation, there is a known issue:
"The secondary display may become disabled after resuming from sleep/hibernation in big desktop mode".
