I´ve got a Pavilion DV7 with some integrated Intel card that uses the i915 driver, and it´s an euphemism to say that the graphics performance is pitifully pathetic compared to the Nvidia GTX470 I´m used to ... However, this laptop also has a Radeon card built in --- only I can´t get it to work. Apparently the laptop is MUX-less, so I don´t get any output to the screen when switching to the discrete card. There are instructions on [1] how to get the Radeon card to work with the fglrx drivers. Unfortunately, an outdated version of the intel drivers seems to be required: Regarding the xf86-video-intel package, it is important to use a version 2.16, as was fortunately noted in the forum post [5] (by bojojo2020). This is because the current version of ati-drivers, 11.12 doesn't seem to work with newer versions of xf86-video-intel. (I was initially unsuccessful with 2.17, and in my opinion, this is perhaps the only detail due to which someone would fail in getting fglrx running.)[1] Debian Testing has version 2.17 of the xserver-xorg-video-intel package and fglrx-glx in version 11-12-1. I´ve tried the fglrx drivers; they complain about not finding a library when setting them up, and running startx only produced a segmentation fault with them. Is there any way to get the Radeon card to work in Debian Testing?

Thanks Chen, using the modinfo command I can see that I was mispelling... I was using fcb instead of fbc...

Re: [Fwd: Re: enable i915 rc6 save 7 watt on kernel 3.2]
What are you using to measure your laptop power use? The LessWatts.org page recommends an external power meter- I wondered if you have recommendations or tips for a particular type or method? I'm wondering if there is something fairly inexpensive but reliable and possibly useful for other things as well. I mean I know there are tons of gizmos out there, but I prefer the recommendation of a knowlegeable and experienced Linux user :-) I also have the Lenovo T520.

I don't know if there are better method, but I happen to have an inexpensive external power meter, it looks like a plug with a small LCD screen, capable of measure from few watt to 2000watt, display voltage, power factor, and calculate overall power usage, so it is quite handy for home use.
