Fixing the lid-switch problem (blank screen)
Hello all,
I've recently gotten a Dell D610 from work. When closing the lid, and opening again the screen remained blank.
After some digging, I came up with this script which restores the LCD when you open the lid.
It requires the ACPI VIDEO module loaded.
Create the file /etc/acpi/lidswitch.sh, with content:
#!/bin/sh
# /etc/acpi/lidswitch.sh
# Re-activates the screen when the lid is opened again
LID_STATE="/proc/acpi/button/lid/LID/state"
LCD_STATE="/proc/acpi/video/VID/LCD/state"
grep -q open $LID_STATE
if [ $? -eq 0 ]; then
echo 0x80000001 > $LCD_STATE
fi
[/code]
Put this in /etc/acpi/events/lidswitch:
# /etc/acpi/events/lidswitch
# This is called when the lid is closed or opened and calls
# /etc/acpi/lidswitch.sh for further processing.
event=button[ /]lid
action=/etc/acpi/lidswitch.sh
This effectively makes my LCD come back to life.

Hi. You answered a question off here http://askubuntu.com/questions/248967/laptop-screen-stays-blank-after-lid-is-reopened with this answer. I'm having the same problem and would like to try this solution, but I don't understand where I'm even suppose to start with this solution. Could you walk me through it with steps? Thank you.
