change to

GRUB_CMDLINE_LINUX="quiet splash i915.lvds_downclock=1 i915.i915_enable_fbc=1 acpi=force"
if that does not work then install the lastest kernel by ubuntu
http://kernel.ubuntu.com/~kernel-ppa...3.6.3-quantal/
use this to diagnosis powerusage
Code:
sudo apt-get install powertop
sudo powertop
I actually just realized I put them on the wrong bit. I did it on GRUB_CMDLINE_LINUX_DEFAULT because thats where quiet splash is on my. I have acpi_backlight=vendor on the one you are talking about so I guess that replaced quiet splash. I'll add these to the correct line and see what happens..
Update: Well not sure if its working.. When running chrome it goes to about 65C and idle its at about 59-60C...
This is my grub:
Code:
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
# info -f grub -n 'Simple configuration'
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX="acpi_backlight=vendor i915.lvds_downclock=1 i915.i915_enable_fbc=1 acpi=force"
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
and this is the results of powertop

Also... Why are these forums so incredibly, mind numbingly slow?
