Hello, new Linux user here. I’ve recently installed Kubuntu 18.04 as a secondary (but preferred) OS next to Windows. I’ve ironed out almost all the kinks, but one thing just perplexes me and I don’t know what to be looking for.
Sometimes I prefer to put my computer to sleep instead of shutting down which works great. But for some reason Linux decides to wake itself from sleep at 4am. It has never successfully stayed asleep for the entire night and will always wake at 4am (used to be 3am but daylight savings changed that).
I’m fairly confident that it is not my mouse/keyboard doing this, they are connected to the PC through USB pass-through on one of my monitors, which I turn off when shutting down/sleeping. And since there is such a consistent time that it happens it seems extremely unlikely that a USB device is causing it, but I could be wrong.
Here is a pastebin of my journalctl output from yesterday when I booted at ~3:30pm yesterday until this morning. It should also be noted that I only started using the PC this morning ~8:20am which is where a lot of the kscreen logs start happening.
Any help here would be appreciated or any suggestions on where to go from here or what to look into?
