Hi, sorry for answering late. I had no access to the PC to run the test.Actually the splash parameter was not set. I started linux without the quiet parameter then stopped it with : sudo shutdown -h now as you suggested.Same behaviour: the PC displays briefly a few lines then goes to a black screen but does not power off.ChristianEnvoyé depuis mon smartphone Linux Android -------- Message d'origine --------De : Marc Haber <mh+debian-packa...@zugschlus.de> Date : 05/11/2019 10:26 (GMT+01:00) À : Christian Quentin <christian.quen...@architecte-du-web.com>, 943...@bugs.debian.org, 943791-submit...@bugs.debian.org Objet : Re: Bug#943791: general: laptop HP 15_bw0xx does not power-off properly On Tue, Oct 29, 2019 at 09:18:19PM +0100, Christian Quentin wrote:> * when I ask Debian to stop (from Gnome), the shutdown sequence seems to follow> the usual steps, the a blank screen appears.The screen is not completely off.> The PC does not power-off.> * As the PC does not stop, I have to press the power button 10 seconds which> does not seem to be the best way to stop a computer.> * I would expect the shutdown sequence to power-off the computer completely.> * Hint : shutting down Windows 10 (also present on this computer) works fine.What does happen when you start your Debian without the "quiet splash"boot option and shut it down with "sudo shutdown -h now"?GreetingsMarc
