Samsung Series 9 NP900X4C-A04US lid state not detected in ubuntu 13.10.

[mluser]

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.

On my way to 13.10 from 12.04 I did upgrade to 13.04 and lid state change was working properly.

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

I have tested as requested with linux-image-3.12.0-999-generic_3.12.0-999.201309300405_amd64.deb.
Still no change with lid state as reported by cat /proc/acpi/button/lid/LID0/state
Please let me know if there is anything else you'd like me to test.

Thanks

I am running Ubuntu 13.04 and I've just noticed that closing the lid doesn't suspend my NP900X4C.

This is new to me - I've had the laptop close to a year now and this always worked. I don't know when it stopped working.

[mmalmeida (mmalmeida)]

I forgot to add that closing the lid turns the screen off instead of suspending.

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

Actually I marked it invalid, since there was not 'Resolved' option. Invalid makes more sense since it really had nothing to do with the OS. Thanks again.
