I am experiencing the same problem. I'm on a Dell XPS ultrabook with the Dell Sputnik PPAs. In my case, I hibernate the computer (I do not suspend) bu the symptoms are the same.
Also, after coming back from hibernation, the bluetooth widget shows that bluetooth is enabled even though I had disabled it before going into hibernation. # uname -a Linux hostname 3.2.0-38-generic-pae #61+kamal14~DellXPS-Ubuntu SMP Fri Feb 22 20:53:54 UTC 2013 i686 i686 i386 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/935778 Title: Various Toshiba laptops - brightness controls work on first boot, but do nothing after suspend/resume to RAM.
