Public bug reported:
Over the last 20 years, I've owned a succession of Thinkpad laptops.
Every previous laptop has switched the screen off when I close the lid.
I've just purchased a Thinkpad X9 15 that doesn't. When I close the lid,
the screen stays on.
I have the following set in /etc/systemd/logind.conf:
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore
I could set these to suspend, but this isn't a solution because then
things wouldn't run in the background overnight, in particular
Thunderbird's spam filtering.
I have managed to work around the problem using the following:
/etc/acpi/events/lid-close:
event=button/lid LID close
action=/etc/acpi/lid-close.sh
/etc/acpi/events/lid-open:
event=button/lid LID open
action=/etc/acpi/lid-open.sh
/etc/acpi/lid-close.sh:
#!/bin/sh
su - alistair -c 'gsettings set org.gnome.desktop.session idle-delay 1'
/etc/acpi/lid-open.sh:
#!/bin/sh
su - alistair -c 'gsettings set org.gnome.desktop.session idle-delay 3600'
and this seems to work well. It would be good, however, to have Ubuntu
properly support this.
I installed the laptop a few weeks ago using Ubuntu 25.04. Yesterday I
upgraded to 25.10 to see if this would improve matters, but it didn't.
