I have an Alienware laptop that has Nvidia GTX 880M hardware driven by
this driver. I recently purchased an ASUS_VN289H monitor. When my system
gives a blanking command, the monitor returns some sort of lost signal
message which causes the monitor to unblank and the time out I requested
is cancelled. This is probably more of an HDMI question than specific to
this hardware, but I was wondering if there was any way to control what
signals generated buy the monitor are passed up the chain, and if they
can be filtered. I also have an ACER monitor that does not do this.
Sorry if this is off topic for this list. Any pointer would be appreciated.
Don

I cannot get xset to blank the screen, so I added consoleblank=600 in the grub file to be added to the kernel command line. The system blanks after 10 minutes, as expected. The monitor then displays "HDMI/MHL-1 NO SIGNAL", the monitor blanks, prints another message that says nothing and the monitor is unblanked. I believe that the monitor is sending some sort of "NO SIGNAL" message back to the system, which interprets it to mean send the video signal again. I assumed that there was a message sent by the monitor, interpreted by the driver, and some signal was sent to the OS to unblank the monitor.

What happens if you do sleep 1 && xset dpms force off I assume the same thing. What could be happening is that the monitor effectively disconnects (and shows the "no signal" message), and then reconnects. Then the graphics card notices "hey, a new monitor is connected", which triggers all the usual "I just plugged in a new monitor" actions. This would imply that the monitor is messing up since I'm pretty sure it's not supposed to trigger a hotplug when blanking. You could boot with drm.debug=0x1e which should print a ton of info about what all is going on. -ilia _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau ^ permalink raw reply [flat|nested] 10+ messages in thread

I issued the: sleep 1 && xset dpms force off command, and the the next dmesg dump included lines after 74.948936. I then issued the command again and the dump lines repeated as you can see. Please share you thoughts, and thanks for your help.

This is a little out of my league :( By the way, I notice that your GPU is having trouble bringing up its acceleration unit. We added a workaround to reset the GPU harder when bringing it up which should hopefully resolve that issue, available in kernel 4.4. But I don't think it affects your situation. -ilia _______________________________________________ Nouveau mailing list Nouveau@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/nouveau ^ permalink raw reply [flat|nested] 10+ messages in thread

But I get an internal error message stating that there is "unknown udev device /dev/disk/by-id/wwnQx5002538844584d30-part2" I filed a bug report last week, but no action has been taken yet. openSuse Leap does not appear to like Samsung SSDs:-) My 13.2 system (current) has been running on them for a year.
