Black screen after sleep. Asus EEE1025

On some hardware putting the video card in the suspend state and recovering from it needs some special quirk handling.
Read the manual.

Code:

man pm-suspend

Thanks - Didn't know about the manual..

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

Code:

sudo pm-suspend --quirk-reset-brightness

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.

Testing a quirk seems to work initially but after creating the "my-quirk" file it no longer works..
Does the my-quirk file need referenced in a script or ?? (Like adding to grub to activate the file - just as an example)
Can the quirk file have multiple lines of parameters like:

Code:

ADD_PARAMETERS=pm-suspend --quirk-reset-brightness
ADD_PARAMETERS=pm-hibernate --quirk-reset-brightness

Or should I have a separate my-quirk for each function
I know I can string additional quirks on a line

Code:

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

You can put the pc to suspend without sudo with dbus-send.

Code:

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

Is this another way to suspend the vs pm-suspend? I tested with by closing the lid

Thanks again!!
