Re: Lenovo IdeaPad 320 laptop doesn't wake up after suspend

I have a Lenovo IdeaPad 320 laptop with Debian testing/buster and Linux 4.18.5. When I close the lid and open it again, the screen is black, and I can't do anything. I can't even ctrl-alt-F3 to a vterm. At this point I need to restart the laptop every time I close the lid.

Does anyone have any suggestions how to fix this? I have CONFIG_SUSPEND=y set in my kernel.

You may want to add more information to your post. Are you running 'X' with a desktop, and if so, which one?

When you open the lid, is the computer still powered on? Are any indicator lights still on?

Many desktop's (kde, gnome) have settings for lid events that will allow the system to ignore when the lid is opened or closed. I am running enlightenment desktop and when I use the computer for a media player, I have it set to ignore lid events so I can close the lid and continue to watch the media on an external monitor.

As far as coming back from suspension, you may have to look and see if you are set up to suspend from ram or from a temporary file. There may be some settings that have to be tweeked or this may be caused by a bug in your video driver.
