I have the same issue with my HTPC, using a brand new Pioneer receiver (and the same with a older Marantz). Switching either of those receivers in standby is probably similar to just pulling out the hdmi-plug.
In the Xorg.0.log I see this, when I turn a receiver off: (II) NVIDIA(0): Setting mode "NULL" And when the receiver is turned back on again, I see the normal report of its EDID information. I have another workaround to switch it back on again, since I use x11vnc, I have access to my display server via the network. Using nvidia-settings I can see under "X Server Display Configuration" it has switched the "Resolution" to off. Switching that back to Auto or 1920x1080 also re-enables my screen. When I do that, I see this in the Xorg.0.log: (II) NVIDIA(0): Setting mode "DPY-1:1920x1080+0+0" It'd be nice if it did that automatically when the screen is turned on again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1268151 Title: DPMS support broken, fails to wake up the monitor after putting it to sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-331/+bug/1268151/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
