You have been subscribed to a public bug: I have configured the host screen with two monitors extending the desktop. They are both configured at 3840x2160, scale 150%, fractional scaling: yes.
After a period of inactivity, the screens get blanked as configured. When I move the mouse and the screens unblank, sometimes (not always) the configuration is changed by mirroring the same content on the two displays. Anyway, the display are still configured as extended in the applet. Trying to change some settings to restore the desired configuration never work. I have to unbplug and re-plug the second monitor. But sometimes, after unplugging and replugging the secondary monitor, the session crashes, all the apps are terminated and I get just the logon screen. In other words, gnome is not able to manage reliably the blank/unblank cycle in a multi-monitor configuration. I also tried with the AMD built-in graphics card and the behavior is exactly the same. Therefore I donĀ“t think that the NVidia driver has anything to do with it.
