Date: Tue, 25 Feb 2025 15:50:55 +0100

Hello,

After rebooting with ‘reboot -k’, my laptop’s screen remains blank.  I
have to type my LUKS passphrase blindly and then it boots fine, even
displays stuff normally on its external monitor, but its own monitor
remains desperately blank.

That’s a 2016 HP laptop with Intel graphics.

Are there known remedies?

At the Guix Days, someday said they experienced a similar problem.

Ludo’.
