[Bug 392812] Re: Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail

[rengolin]

I've reinstalled Ubuntu 9.10 from scratch (CD), updated up-front and
installed the ATI drivers. Still not working. Brightness and lid
operations work fine for a few minutes than stop working.

Just to let it clear, suspend and hibernate work perfectly when choosing
it from the shutdown menu. ACPI is working fine, the problem seems to be
recognizing the buttons.

I ran the lid.sh while the lid was close (via timer) and saw that it
never passes this line:

if [ `CheckPolicy` = 0 ]; then exit; fi

I believe it's the Gnome messing up the configuration, rather than ACPI
being faulty. I'll try to kill most gnome applications after the problem
appears and see if one of them is the guilty part.
