OK, I think I have resolved my problems with suspend on lid close and they had
nothing to do with K/Ubuntu.
First of all, the power button problem I described above was caused by some
acpid scripts in /etc/acpi, after I uninstalled it, pressing the power button
would put the laptop to sleep just as I had setup in the system power
management settings.
As far as the lid is concerned, it turned out to be a problem with my last bios
upgrade. Apparently you are supposed to completely power down the bios
(separate it from the battery) for a few seconds so the new bios settings can
take effect. To do this one has to depress a tiny little button in the bottom
of the laptop using a paperclip while the laptop is disconnected from a power
source. To start it again, you first have to connect a powersource to the
laptop, or it wont start.
After I did this, everything started working fine. Infact everything is
working perfectly on my
NP900X4C-A04US Samsung laptop. I’m loving the new 10.10 release.
As far as comment #6 is concerned, I believe the screen turning off on lid
close is being controlled by the hardware and not the OS. So that behavior is
normal and expected.
I hope this helps others out there.. took me a whole month and a half to figure
this out.
I’m now going to mark this bug as resolved.
Thanks

Title:
Samsung Series 9 NP900X4C-A04US lid state not detected in ubuntu
13.10.
Status in “linux” package in Ubuntu:
Invalid
Bug description:
I have had no problems with suspend on laptop lid close for over a year,
using 12.04. But since my upgrade to 13.10 I no longer get any lid state
messages.
cat /proc/acpi/button/lid/LID0/state
always shows state: open.
In 12.04 my keyboard backlight never worked, and now in 13.10 it does. I also
used to be able to put the laptop to sleep by pressing the power button, but in
13.10 that is not working either.
Everything else is working perfectly, except for the lid state changes.
On my way to 13.10 from 12.04 I did upgrade to 13.04 and lid state
change was working properly, but bluetooth was not, so I decided to
try 13.10. Bluetooth works fine now.
