cooling fan weirdness with Karmic and a Satellite L305-S5955

[Matthew T.]

I've always had problems with the cooling fan in this lappy working
properly under Ubuntu. I was able to get it to work in Jaunty by
adding 'acpi_osi="Linux"' to the kernel boot parameters in menu.lst.
In Karmic, I have added 'acpi_osi=Linux' to the kernel boot parameters
in /etc/defaults/grub and run update-grub to modify /boot/grub/
grub.cfg.

This doesn't bring me the fullness of joy, however, because the laptop
constantly warms up to about 130 degrees, the fan kicks in, it cools
back down to 109, and the cycle repeats. This happens about every 10
minutes with only 3% CPU usage. The temperature seemed to be alot more
consistent under Jaunty. Suggestions?

Use Jaunty? I don't know if it is an LTS, but it should still have support
for a while, given Ubuntu's policies.

Outside of that, I'd guess a bug on launchpad against the kernel might be in
order, although that should be preceded with a similar post to an Ubuntu-
specific mailing list and a trek through the Kernel documentation --
particularly any documentation on the acpi_osi kernel/module option.

I've yet to own any hardware that needed specific kernel command-line options.

Thanks for reminding me of launchpad. I believe I have found the
solution in the alternate kernel which is linked to at

The patched kernel turned out to only be a temporary fix. Or maybe
there was some other issue causing the cooling fan to work properly
for a time. I tried Debian on the laptop just long enough to find out
that it didn't see my wireless chip, then installed Arch. Definitely
the most involved installation process I've experienced so far
(Slackware held this title until previously) but the cooling fan
issues were easy to address and solve. I was doing command line
installs in Ubuntu to just get the apps I wanted, so Arch is something
like a big step in the same direction for me. And it's forcing more to
learn more about Linux in spite of gui tendencies.
