Hi Galen,

Please confirm if you are running Linux Lite 1.0.8?

Thanks
Scott

2.2

Re: power manager, laptop lid locking bugs - galen - 05-04-2015

still a bug in LL 2.4 on HP nc4400
after returning from a suspend (lid close set to suspend)
login manager appears but quite dark,
after password entry screen goes black,
nothing revives nor wakes the screen.
Sometimes going blindly to a terminal tty1 and ctrl-alt-del the system will reboot
other times the system will hang and power switch does nothing.
That hard lock requires power and battery removal.

Lite locker is not used.

Hello Galen,

Made some research on this.
From the pm-utils

Code:
man pm-suspend

try running sudo pm-suspend with some of the quirks
For example:

Code:
sudo pm-suspend --quirk-vbe-post --quirk-vbemode-restore

Code:
sudo pm-suspend --quirk-reset-brightness

Code:
sudo pm-suspend --quirk-dpms-on

All the quirks:

Code:
  --quirk-dpms-on

  --quirk-dpms-suspend

  --quirk-radeon-off

  --quirk-reset-brightness

  --quirk-s3-bios

  --quirk-s3-mode

  --quirk-vbe-post

  --quirk-vbemode-restore

  --quirk-vbestate-restore

  --quirk-vga-mode-3

  --quirk-none

The trick is finding the right combination. It could be just one parameter or several.
When you find the right quirk. Test your system to see if all is running OK.

From the manual, to save it create a file in /etc/pm/config.d/
Name it anyway you like.

Code:
gksu leafpad /etc/pm/config.d/my-quirk

containing

Code:
ADD_PARAMETERS="pm-suspend --quirk-vbe-post --quirk-vbemode-restore"

to make the quirk stick. Just use the parameters that work for you.
Which quirk works depends on your hardware, kernel, driver, KMS settings and the probably the phase of the moon. Smile

Save. After reboot it should work.

Code:
dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend

UPower should use those parameters.

https://wiki.ubuntu.com/UnderstandingSuspend
Hope that helps.
I got this mostly from reading the manuals. Also I've had a look on this:
https://www.kernel.org/doc/Documentation/power/video.txt
and acpi_sleep kernel parameters here
https://www.kernel.org/doc/Documentation/kernel-parameters.txt
EDIT: I forgot to mention you need nomodeset for this to work.
Do this first:

Code:
sudo nano /etc/default/grub

and then adding nomodeset to the line which reads GRUB_CMDLINE_LINUX_DEFAULT Then close nano saving the modifications (Ctrl+x, y, enter)
and then finally

Code:
sudo update-grub

to implement the changes. Then restart.
After that you can verify that

Code:
cat /proc/cmdline

contains nomodeset.

Hello!

Well, the 'quirk-radeon-off' worked for me - no 'nomodeset' needed. I tried using nomodeset, and it threw me back to the default video driver and 1024x768 resolution, so I turned it back off again.

I will try some of these 'quirks' on some of the other laptops I have that misbehave when the lid closes...

Re: power manager, laptop lid locking bugs - galen - 05-06-2015

thanks misko that was great information

I tried many quirks and the system returned healthy from many suspends.
I added my-quirk
Did not use nomodeset.

Still buggy when lid is closed.
What else could over riding the power management ?
Checked /var/log/pm-powersave.log
dmesg etc..
nothing is showing a fail.

If I close the lid, the system comes back buggy whether lock lid or suspend is used.
I'll dig so more

Glad it worked for you and thank you for letting me know `nomodeset` isn't needed.
Quirk sounds nicer than a `hack` Wink

No problem Galen. I learned something along the way.

Nothing I can think of. Have you tried different kernel?
Check the BIOS settings, maybe changing something in there would help.
Or maybe just updating microcode would help (not sure).
