[Bug 563156] Re: [ATI Graphics][Lucid] laptop runs hot, shorter battery life, fan always on

[Vanessa Ezekowitz]

Similar problem here with a Dell Inspiron 9200 with ATI graphics, and
it's about the same story as others above:  The laptop's fan is on as
long as the machine is awake, regardless of total CPU load (which is
usually negligible), and the battery life seems unusually short (I'm
down to half charge in less than an hour).  Battery life was
considerably better under Karmic (a full charge was good for 3-4 hours).

For me, this regression is the result of an upgrade from Karmic to Lucid
via Synaptic, rather than a full re-install.  I had to use the
instructions at http://news.softpedia.com/news/How-to-Fix-the-Big-and-
Ugly-Plymouth-Logo-in-Ubuntu-10-04-140810.shtml to fix the bootsplash
that broke during the upgrade.  That How-To happens to include the
"nomodeset" boot option, which fixes resume-from-suspend for me as well
(Lucid fails to turn the backlight back on otherwise).  I mention these
in case there is some connection between those settings and the power
consumption issue.

I am running the regular open-source "radeon" driver, and "Hardware
Drivers" gives me no option to install any other drivers (of any kind).
