Daniel, not sure if they're related, but it seems that when I get back from the "slide" screen (even if not locked) I'm getting a lot of these errors repeated in journalctl:

I can't move the mouse or type anything. After a while, it unfreezes. This is quite annoying because often the freeze is long enough to send the screen to standby again for absence of singal, so then I have to wake it up and wait again. This is not 100% reproducible but happens very frequently, both when the screen is locked and when it's not.
