[Virtual-pkg-base-maintainers] Bug#758110: base: suspend to ram key (Fn+F4) does not work anymore

[Cédric Roux]

Package: base
Severity: normal

Dear Maintainer,

I did an upgrade of Debian testing yesterday and since then the Fn+F4
key on the laptop (ACER timeline X 5820TZG) does not suspend to RAM anymore.

I removed (apt-get purge) acpid, acpi-supoprt, acpi-support-base.

I use fvwm, not gnome/kde, that I run with startx.

I tried a cold boot, I tried in a linux console (i.e. no X).

I see that the key press is visible in /dev/input/event0 (the keyboard).
I see with xev that it is reported as keysym "XF86Sleep" in the X world.

I tried to look on the internet but could not find something that
helps, thus this email.

The apt-get dist-upgrade of yesterday seems to have installed systemd
instead of what was there before. It might be related, but:
journalctl -u systemd-logind.service -b
reports:
Watching system buttons on /dev/input/event3 (Sleep Button)
So I don't think the problem is there.
I suspect the kernel, since /dev/input/event3 seems to be
silent (cat /dev/input/event3 shows nothing, whereas
cat /dev/input/event0 does).

Thanks for any hint. If you don't have enough information, I may
provide more.

Regards,
Cédric.
