Monitor doesn't stay in standby when using a DP cable
by MirceaKitsune from LinuxQuestions.org on (#51WVT)
Having another little issue with my new monitor. I switched the connection from a HDMI cable to a DP one, as there are a few improvements to using DisplayPort instead. This introduces a small annoyance I don't know how to fix.
Whenever the monitor goes into standby, it only stays that way for a few seconds before turning itself back on. Power Management - Energy Saving - Screen Energy Saving is set to 5 minutes; The OS does indeed power the monitor off after this idle time and I even see its power LED indicating that. However it only stays this way for roughly 6 - 8 seconds: Despite not moving the mouse or pressing any key, the monitor always powers back on after this amount before I do so. The problem only started after changing the cable type.
Anyone else experiencing this issue and knows how to solve it? Is this perhaps a kernel / X11 bug that I should report? openSUSE Tumbleweed x64 KDE, amdgpu module, monitor is a ViewSonic VX2758-C-MHD 23.6.
