Hi!

My laptop has previously suspended on lid close with external monitor
connected. It does not anymore.

It suspends on lid close without any external monitor connected.

Did it work with 0.142-3?

It should have, but I have tried 0.142-2 and 0.142-3 from snapshots.d.o
now without any success.

I have checked pm-utils and xfce4-power-manager but those have not
changed recently.

At the same time as I upgraded acpi-support I also installed
linux-image-3.16-1-amd64 3.16.2-3. I tried with previously installed
kernels 3.14 and also 3.12, still no dice. With the 3.12 kernel the
external monitor is turned off briefly when the lid is closed, but the
laptop never suspends. The laptop suspends without the monitor
connected, but does not lock the screensaver, see #762176.

I also installed laptop-mode-tools, but have tried removing it and the
laptop still does not suspend with the external monitor connected.

Is xfce4-power-manager running? If so, the problem almost surely does not lie
in acpisupport.

acpi-support only handles these events only if no other software that is supposed to handle the same is running. One of the checks done is this:

        PMS="/usr/bin/xfce4-power-manager /usr/bin/mate-power-manager /usr/lib/dalston/dalston-power-applet"
        pidof -x $PMS > /dev/null [...]

I guess this return success on your system meaning the acpi-support script in
question should immediately exit.

I have of course tried with mixed scenarios where xfce4-power-manager
have not been running also. :-)

This has probably been handled by xfce4-power-manager on my laptop
previously. The bug report is still valid though, since acpi-support
does not suspend with the external monitor connected.

Ah, that woul dhave been so easy. :)

Does pm-suspend called by itself suspend?

It does, with external monitor connected.

Then, I'm afraid, we need some more debugging. Maybe the same reason as the other bug.
