LCD does not wake up

LCD does not wake up

[Hadmut Danisch]

Hi,

is there any FAQ about ACPI problems?

I have an MSI S260 (Intel chipset) with
kernel 2.6.11.7. 

An  echo mem > /sys/power/state  works well, 
the machine goes into suspend state and wakes up 
properly except for one thing: The LCD remains black,
backlight is not turned on.

How can I turn the display on?

regards
Hadmut

Oh, lucky you! Mine is a sleepyhead and doesn't want to wake up at all

Try `dpms on`. You can find the tool here:
