Screensaver quit working?
I have a box running Kali with the MATE desktop. I just switched to a new wiiiiiide monitor, and my screensaver no longer kicks in, ever.
I have tried refreshing its settings, etc. If I invoke it manually with Super+L it starts. But it never powers off the monitor.
What could cause this? What else might I try to at least isolate the cause?
Have you tried switching back to your old monitor? It could be a firmware issue.
Are you using wayland or x11 under MATE? You could change your display protocol to either one or the other and see if the problem still occurs.
I hope that helps in narrowing down the cause of the problem.
@IntheMesh Using X11. Wayland is still pretty glitchy, I seem to hear? Makes me leery of it.
