I iiyama_ProLite_XB2776QShave absolutely no idea for that behaviour. I have to following combination: iiyama ProLite XB2776QS MSI GeForce GTX 980 Gaming 4G (GM204) nvidia driver 355.06 When I use DVI-cable, that the display goes into energy saving mode after a while. When I use a DisplayPort-cable, the display is always in on-mode. When triggering suspend mode with "xset dpms force suspend", the display shows a black screen. I check the mode of the display with its power indicator (LED): blue means on, orange means power saving mode. Reproducible: Always Steps to Reproduce: 1. use a DisplayPort cable instead of DVI 2. try getting display into power saving mode Expected Results: Energy Saving modes (suspand, standby, ...) should work with all kind of digital cable connection. Modern graphic cards tend to offer more and more DisplayPorts (or Mini) only. I a multi monitor setup I could use my working DVI, but for the second display I have to use DisplayPort. HDMI ist no real Option, because combination of resolution and refresh rate seems to be limited to FullHD/60Hz.
guessing source to be nvidia-drivers.
jer: what info exactly is required?
What does the status "RESOLVED NEEDINFO" mean? Sounds like a joke. Do you even own a nvidia graphics card? Did You try the the described steps to reproduce the bug? This was my last bug report. Greetings.
