Created attachment 127455 [details] Xorg.log with logverbose 20 Hi. The problem is that the intel driver seems to ignoring the: Option "DPMS" "false" of the associated monitor section in the xorg.conf. Expected behavior: If a monitor has "DPMS" set to "false" the monitor should stay powered on, even after typing "xset dpms force off"/or DPMS enabled by the window manager. Current behavior: The monitor is powered down. I was also testing to put "DPMS" "false" to all monitors associated with the intel driver - the result was the same => all monitors went sleep. Other drivers (tested on nvidia and nouveau) honors this option and monitor with the above option set is not turned off, while the others are. As a side note, I can see a difference in parsing the option by the driver, because when all intel-driven monitors are without the DPMS option, then I have in the log: [ 147.737] (==) intel(0): DPMS enabled [ 147.737] (==) intel(1): DPMS enabled and when I disable DPMS for monitor0, then in the log is only one line: [ 147.737] (==) intel(1): DPMS enabled I am attaching my xorg.conf and the log with .

The blanking came in via dixSaveScreens, oddly. commit b7d6f695ddab02b7afef0f1ca3ae132f4fdbfd43 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Oct 21 23:11:42 2016 +0100 sna: Disable screen saver if Option "DPMS" is specified The defacto standard is that the screensaver only blanks the screen but keeps the outputs alive. We differ by actually disabling the CRTC when the screen saver kicks in (to save power), however this circumvents Option "DPMS".

Chris, First of all thank you for quick response and a fix. Unfortunately your fix is working partially: Any monitor with "DPMS" "false" option is not showing anything besides the last console state. I mean the following: when I am starting xorg from console then after starting Xorg, all monitors are showing my wallpaper from my window manager, but the one with DPMS=false has this console texts frozen (cursor is not blinking). The good news is: when I tested it with "xset dpms force off", then mentioned monitor did not power off, while the second one connected to intel driver (without specified DPMS option) went sleep correctly, so in this area the patch is working fine :) Steps to reproduce: Set the "DPMS" "false" option in the monitor section, and see that Xorg is not "rendering" anything on it.
Chris, After applying 90172d81ea762eeca4cfb3796fab83cff9f0acaa everything is now working great as expected. Thank you very much!!! :)
