I can confirm that there is definitely dpms breakage in recent nvidia-drivers. 352.21 - works 352.30 - works 352.41 - I haven't tried yet 355.06-r1 - broken 355.11 - broken By broken I mean that with these two versions the backlight never turns off. "xset dpms force off" merely blanks the screen, the backlight stays on indefinitely. By works, I mean that "xset dpms force off" immediately blanks the screen and turns off the backlight as it always has. I haven't tried 352.41 yet--but sounds like from this report the issue may have been introduced between 352.30 and 352.41. I can confirm after update to x11-drivers/nvidia-drivers-355.11 from 352.30 dpms is also broken for me. My emerge --info output can be found here: https://bugs.gentoo.org/show_bug.cgi?id=560602#c1 *** Bug 559068 has been marked as a duplicate of this bug. *** Please report this to Nvidia. Gentoo merely distributes their closed source drivers. Sure, it's for them to fix, but in the meantime I suggest not marking the affected versions as stable in portage--since this is significant breakage.

The laptop has a mini-display port connector in addition to the HDMI connector. Therefore I tried hooking up my external display via display port. *With* the monitor attached by DP - both monitors/screens resume from off and work correctly. Great - but only if an external DP monitor is connected... So the plot thickens!! according to post #29 here: https://devtalk.nvidia.com/default/topic/791786/linux/dpms-not-working-on-gtx980-with-displayport-connection/2/ Nvidia changelog lists a fix for DPMS on display port connected monitors in version 352.63 released 2015.11.16. So, as soon as that makes it to portage I'll retest. (In reply to Nick Leippe from comment #8) ... > Nvidia changelog lists a fix for DPMS on display port connected monitors in > version 352.63 released 2015.11.16. ... I've tested this driver with the affected system (ASUS G751JT.208 ROG model). The notebook built-in display (DP connected) resumes from DPMS suspend. Resume - from suspend to RAM - still works as well (which is nice)! Thanks for heads up (I've upgraded from 352.30 to 352.63 permanently now). I've posted a comment on the Nvidia dev talk forum thread. |
