The fact that it works with the blob rules out a hardware issue in the converter. I've never heard of anything like this... mind booting with nouveau.debug=PDISP=debug,VBIOS=trace drm.debug=0xe and waiting for the issue to occur, and grabbing dmesg after that? That should give us an idea of who is turning the monitor off. Hi! I don't know, wether a recent update helped (or the new kernel lines ;-) ) - but atm the phenomenon doesn't occur anymore (after weeks of annoyance)... This report can be closed - I'll reopen one, if the problem strikes again! Thanks! |

Created attachment 96893 [details] dmesg > dmesg.txt Dear all, my second monitor, attached via HDMI-DVI-Adapter keeps turning on/off every ~20min. This is independant on what I am doing! The xorg-screen itself seems to remain active (windows can be dragged from and to it). The first monitor remains active. All Standby-Options are turned off (Monitor set to switch off after one hour). I can reactivate the monitor by switching to a text-console (ALT-F1) and back (ALT-F7). nvidia-driver works fine (switched using the provided option of the proprietary drives section of the Softwaremanager, no nvidia remained after switching back to nouveau). lspci | grep VGA 03:00.0 VGA compatible controller: NVIDIA Corporation GF108 [GeForce GT 430] (rev a1) lsb_release -rd Description: Ubuntu Trusty Tahr (development branch) Release: 14.04
