power manager, laptop lid locking bugs

[anon222]

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

or

Code:

sudo pm-suspend --quirk-reset-brightness

or

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.
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.

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.../video.txt
and acpi_sleep kernel parameters here
https://www.kernel.org/doc/Documentation...meters.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.
