I just installed Manjaro on a MacBook Pro from 2011. This is the first time I’ve tried Manjaro and it seems to work very well on this MacBook. However, I mainly use the computer to play music with atm. and every 10-15th minute, or so, the music stops playing for about 5-6 seconds. For some reason the screen lights up when this happens and the login screen is displayed.
Do you have any ideas what’s causing this?
Are you not using the system during this time?
Are you talking about a lockscreen after 10 minutes?
Also … might as well share information like what desktop environment and so on:
inxi -Fazy
Check your system settings - looks like the system is locking due to inactivity - yes I know playing media is not inactivity - it is the lack of physical interaction that is dectected.
From what you’re describing, it sounds like the system is entering sleep mode, but since you’re not telling us what desktop environment you’re using and our crystal ball is in for its annual maintenance, you’re going to have to wade through whatever flavor of System Settings you have in order to disable this automatic sleep mode. For one, it’s bound to throw up trouble if it happens in the middle of an update.
Judging by your (quite common) mistake of confusing the lock screen and the login screen, my guess is that you’d be using Plasma. The login screen (sddm) and the lock screen (kscreenlocker) there do look very similar in appearance, but they are entirely different things.
No, the system is just playing music. It seems to happen every 15th minutes, or so. The screen is black and then the music stops for 6-7 seconds. The screen lights up and the clock, date and “click or press any key to unlock” message is shown.
There’s a lot of output from inxi -Faxy, but here we go

Which setting should I look into?
I’m using Gnome, sorry for not stating that. Also, there are some more details in the posts above here. Thanks for the help. This is a bit annoying since it happens so frequently.
