Title:
Ubuntu 14.04 laptop uses lot of power switchable graphics
Has anyone tried adding radeon.dpm=1 to your grub?
Try:
edit /etc/default/grub and add the 'radeon.dpm=1' to the
GRUB_CMDLINE_LINUX_DEFAULT line, so it would look something like:
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash radeon.dpm=1

I am currently on Ubuntu 14.10 and my time on battery improved significant. The

I am still concerned since the overall heat produced from the laptop is somehow
still much more less on Windows. I am not sure if the

This improvement is just by moving from 14.04 to 14.10.
I just cat'ed my grub config and I do not have radeom.dpm stated there
anymore. It should be active by default anyway.

The wattage consumption has now dropped to 26W on average. However, on
Windows it goes down to 11 - 12W. Seems like it is still not shut down
correctly.

** Description changed:
I have a Samsung Series 7 Chronos 700Z3A-S02DE. It uses an i5-2450m
(Intel HD2000) and an AMD 6490m dedicated graphics card. Since Ubuntu
14.04 uses Linux kernel 3.13 it enables dpm by default. This causes the
graphics card to be shut down to dynoff when not used
Did not changed after adding trusty-proposed and upgrading all packages.
