AMD catalyst


After the last post I had thought that may be because of the graphic card usage the temperature was higher. I then installed the drivers for AMD and got them running. However there still seems a stark difference between when running Fedora as compared to windows.
Is there some other fix by which I could get the temperatures down and thus prevent over usage of the battery.

Does anyone experience this or have a solution? Seems like the settings in power manager are optimal.
Have you installed the nVidia drivers?

Nouveau, the open source drivers shipped with most linux distros, uses more power than the closed surce nVidia drviers. Changing to the closed drivers should give you better battery life (and lower temps ).

The problem is simple, my laptop comes with two vga cards, built-in Intel and nVidia, Fedora was set to use the nVidia as the default causing power loss and heat problems.

The thing is my nVidia graphics card also supports 3D vision and HD sound adapter, which is too much under battery usage, in the other hand Win8 will download these drivers for you once connected to the internet, but with F19 (and preivous Fedora releases) yum won't do that for you.

See this post for more information http://thunderbirdtrr.blogspot.com/2...l#.UjjfAKxx21E.
Dell Inspiron N5110 i5 with nVidia is an 'optimus' system with an nVidia GPU and intel video chip. Optimus (under supported windows OSes) will generally use less power than an nVidia only or intel video only system. But it isnt really supported with linux. There is a project to get 'optimus' systems working better with linux, its 'bumblebee', you really should look at it.

AFAIK, no, fedora wasnt using the nVidia GPU by defualt. It will be running if you havent taken step to shut it down, and that does cause higher power consumption/lower battery life/higher temps.

Be thankfull that Fedora doesnt d/l nVidia drviers automatically, installing the nVidia drivers without bumblebee on an 'optimus' system will just break X.
