<pre>I'm seeing the same symptoms on my laptop as in
<a class="bz_bug_link
bz_status_NEW "
title="NEW --- - Laptop not suspending when lid is closed."
href="show_bug.cgi?id=76267">https://bugs.freedesktop.org/show_bug.cgi?id=76267</a> : closing the lid doesn't
suspend while the suspend button does, but, as I understand, the cause is a
different one so new bug. Please mark as duplicate if I was wrong ;)
In the logs I see this (with SYSTEMD_LOG_LEVEL=debug for logind):
systemd-logind[4178]: Lid closed.
systemd-logind[4178]: Ignoring lid switch request, 2 displays connected.
However there is only one (the integrated) display.
The laptop has two gpus using vgaswitcheroo, an intel igp and a radeon
dedicated gpu, both are working with the free drivers. And both connectors
/sys/class/drm/card0-LVDS-1/status (the igp, actually in use)
and
/sys/class/drm/card1-LVDS-2/status (the radeon gpu, dynamically powered off)
show "connected", so src/login/logind-core.c:manager_count_displays() returns
2.
Is the kernel supposed to advertise two connectors as connected in this case
even though there's only one display? If so, what is a better way to recognize
the actual number of displays connected?
Thanks
Mirco</pre>
