Hello together,
this seems to affect me, too. On Ubuntu 16.4 LTS.
Lots off Syslog lines with:
Feb 2 12:44:01 ws-kollstedt org.kde.KScreen[1925]: kscreen: Primary output
changed from KScreen::Output(Id: 638 , Name: "DVI-I-1" ) ( "DVI-I-1" ) to
KScreen::Output(Id: 638 , Name: "DVI-I-1" ) ( "DVI-I-1" )
Feb 2 12:44:01 ws-kollstedt org.kde.KScreen[1925]: kscreen: Primary output
changed from KScreen::Output(Id: 638 , Name: "DVI-I-1" ) ( "DVI-I-1" ) to
KScreen::Output(Id: 638 , Name: "DVI-I-1" ) ( "DVI-I-1" )
Changes from and to seems to be the same.
Possible side effect, but Im not sure it correlates:
Sometimes the Screen freezes, and after appox 30 seconds the System reboots.
Usually it still works. The toggeling Screen was something i experienced on
2016-11-07, I resolved this by switching to the nvidia-367 package.
