Screen turns black after 30 seconds (on fresh install) [SOLVED]

Hi!

I've just installed arch linux by following the guide on the arch wiki step by step.

Once I boot up everything woks fine but after 30  seconds (measured) the screen turns black. It happens even while i'm typing.

This didn't happen on while installing from the USB.

Thank you!

Hello, welcome to the arch community.

I am kind of a newbie myself, I already have experience with the basic tools and topics, but I don't think I can reliably solve your problem, so someone more experienced is gonna have to help you.

I just came here to say that you need to give us as much information as you can. For example, if you wait for the blackout after 30 seconds logged as root, can you blindly type "systemctl poweroff" followed by enter? This would confirm if you still have access to the terminal.

The output of "journalctl -xeb 1" can help as well if you have the time to read it or take a picture. I believe you can also get the logs by booting from the live usb and copying them to a USB.

But since it's a new system, I'd try installing again. Check the md5sum of the image if you didn't do that the first time. Or at least rebooting from the live usb and and check or redo every step except for the partitioning if you are sure you have it correct.

Sorry I can't be of much help, and good luck.

We need more data.

Console or display server (and if: Xorg or wayland)
Desktop environment?
Did you install some power saving tools?
Does "turn black" mean the backlight turns off?

I've solved the issue. There was a bug with the HandleLidSwitch options of logind.

I've solved it by setting HandleLidSwitch to ignore, following the instructions on this post:

Thank you very much for your help, I'll give more information next time.

Sorry for posting an already existing problem, I didn't know that it was going to hibernation.
