Lid switch on N150-11 causes Suspend only every other time
Posted: 10 Aug 2010, 18:35
Running #!CrunchBang Statler a2 Linux on Samsung N150-11, adding samsung-backlight and samsung-tools made a big improvement, thank you, voRia!
One thing that is not working well is Suspend on lid close -- it works perfectly every other time the lid is closed; the other times it turns off the backlight but does not suspend! This is a safety issue: packing a running netbook could lead to overheating.
CrunchBang is Debian Squeeze based; I am using the XFCE4 version, so xfce4-power-manager. But I suspect the issue is in the kernel or BIOS. If I look at /proc/acpi/button/lid/LID0/state I see that it reports closed every other time the lid is open.
Do you know of any quirk or setting I can make to fix this?
Searching the web I have found several references to this problem, some quite old; most of them refer to ACPI scripts for workarounds, but ACPI is not installed on my system, just HAL, pm, and samsung-tools.
Here are a few relevant links

Have others seen this problem? Have you found a workaround?
Thanks!
