Ubuntu 12.04 missing system hibernate?

I upgraded my Lenovo 3000 V200 Ubuntu 11.10 to 12.04 just recently. And I noticed that my favorite “hibernate” is missing.  So… I read and modified the kernel sources.. recompiled…… JUST KIDDING!!!   I actually googled and found this thread (http://askubuntu.com/questions/94754/how-to-modify-policykit-to-allow-hibernation-in-upower) and it works!!

Just create or modify this file using your favorite file editor (vim works for me!)

/etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla

And put…


[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

A restart (power cycle) to apply the changes and then wooolaaa!!! “hibernate” is back!!

Ubuntu 11.10 no audio in headphone jack

I installed Ubuntu to my Lenovo 3000 V200. Everything works until I found out that my headphone jack is not working.  I tried googling the fix that leads me to this link:

then following this:
