Laptop won't suspend with HDMI connected

English Install/Boot/Login
1

HP laptop, Intel integrated graphics, KDE plasma.

Suspend worked normally when closing the lid. My daughter closed the lid yesterday, with the HDMI cable connected to a TV that was turned off (it has no standby, apparently).

Today (before updates) the laptop was very hot. It didn’t suspend, just turned off the laptop display and switched the primary display to the TV.

If I disconnect the HDMI cable it suspends normally.

Same behavior after updates today. Last update before today was probably a couple months ago.

Any ideas?

Thanks!

Not really.

It sounds as if it might be a deliberate design feature – when watching TV, you can close the lid. Maybe look to see if there are any relevant BIOS settings.

Hi
Or some conflict with logind which has happened in the past with Plasma
from memory…

I always set lid switch to ignore in /etc/systemd/logind.conf.

The thing is that, AFAIR it did suspend before, HDMI connected or not.

What would this do? Disable suspend or force it?

Hi
Unfortunately I don’t have a suggestion, it was just an observation
that in the past Plasma and logind had some issues maybe last year,
maybe a new issue has developed which your seeing…

I close the laptop lid, I set this so it keeps running…

Hi, Malcolm, and thanks.

Actually, I think nrickert is right. My daughter returned from a holiday today and told me it have always behaved like that, so my mistake. Apparently, AFAIR does not go far at all :wink:
