Dual Monitors - one doesn't turn back on
Setup:
I have two monitors running off of a single ATI (R9 270X) graphics card. The problem monitor is a WQHD monitor connected miniDP-DP and the other is an older 1440x900 connected miniDP-DVI. My WM is Openbox. My system is up to date and I'm running the basic kernel.
Problem:
When I turn off the problem monitor, tint2 flashes, but no windows are moved or anything. When I try to turn on the monitor, the light comes on, but the screen is black. Looking at xrandr and X logs, nothing suspicious seems to be going on or changing at all. Changing window managers (tried PekWM) doesn't seem to do anything. Turning on and off the other monitor acts as expected.
Workaround:
After much testing, I found that instead of rebooting, I could get the screen to turn on by turning them both off with
xset dpms force offand then when I woke them, they both turned on.
Clues:
Something interesting I found is a discrepancy in DPMS capabilities between the monitors. For the problem monitor "DPMS capabilities: Off" and for the other "DPMS capabilities: StandBy Suspend Off."
