Black Screen right after turn on

Hello Everyone. I use hyprland as my window manager. When I turn my laptop on, I get the grub menu properly, the texts flows around my screen and suddenly, my computer stops working. It turns into black screen without anything. I changed tty with CTRL+ALT+F() And I get this error after logging through CLI:

 Start Hyprland with command Hyprland
Error: i/o timeout

I checked status of Hyprland via systemctl status, and it said

 Unit hyprland.service could not be found.

Any help please?

Re: Black Screen right after turn on

How are you starting hyprland? There is no and has never been a systemd service for hyprland specifically. After reproducing, and switching to a tty, post the link you get from

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Re: Black Screen right after turn on

I got this from journalctl:
http://0x0.st/88gm.txt

Everything was going well before this error. I didn't change any file I think. I can simply command: hyprland after changing tty in that black screen. And I think the problem is about the sddm, because when I try to exit from menu or command 'sddm' on terminal, I get this error:

 ~
❯ sddm

I'm sorry if I'm wrong.

Re: Black Screen right after turn on

Not sure if this was solved but sddm is not designed (afaik) to be run from the terminal like that.

Instead you should tell systemd to start sddm at boot, with the following :-

sudo systemctl enable sddm

Now when your pc has finished it's boot process, it will automatically start sddm and present you with the graphical login prompt.
