I am running xfce 4.11. Power manager is configured to do nothing when the lid 
closes.
When I close the lid, I get ACPI events and that trigger the /etc/acpi/lid.sh 
scipt.
this script in turn calls "CheckPolicy" which returns 0 since xfce4 power 
manager is running and the lid.sh script exits before actually doing anything. 
In particular, when I open the lid, 'xset dpms force on' does not get called 
and the screen stays dark.


looks to me, the acpi script relinquishes all duties to xfce4-power-manager - 
as it should - but xfce4-power-manager does not turn power to the screen back 
on.

Are you using xfpm in combination with logind/systemd?

I presume by xfpm you are referring to xfce4-power-manager? If so, then
yes, it is running along with upowerd, at least both show up in "ps -e"

not sure about logind/systemd: to my knowledge I didn't do anything here
that wasn't out of the box. I'd be happy to run any diagnostics you need
and post it here.

Yes, xfpm was intended as shorthand for xfce4-power-manager.

What version of what distro are you using?

I originally installed Ubuntu 12.04.03 LTS 64 bit which I subsequently
upgraded to Xubuntu. The problem thus occured under Xubuntu 12.04 LTS 64

Restore screen power after sleep

With this patch xfpm will cache the brightness level before going to
sleep and set it back to that level after resuming from sleep.

Running Xfce 4.10
xfce4-power-manager-1.2.0-9.fc20.x86_64
Kernel 3.15.10-200.fc20.x86_64
xscreensaver-base-5.29-1.fc20.x86_64

With the 3.15.x kernel came a problem with the screen not restoring from
suspend. I had a thread going about this on Fedora Forums and had been
following a bugzilla report. However, I now believe the problem is in
how xfce4-power-manager handles restore.

If I use the power manager settings and have the option on the Extended
tab for "Lock screen on suspend" checked, this problem shows up. I was
looking at this and unchecked the option, and the system now resumes and
restores the screen display properly upon resume from suspend.

I tried this with both the stock open-source radeon driver and the AMD
Catalyst driver.

I do not know what changed between the 3.14 and 3.15 kernels that caused
this problem to manifest. I'm also not sure if xscreensaver has anything
to do with this. I do not have power management enabled there.
