[tlinux-users 00138] Re: Request a new info: fan control documentation for Toshiba A300

[Ilyes Gouta]

Hi Thomas,

Do you know about a way to ensure that the video card fan is spinning
under Linux? This is actually on my TODO list to get my Satellite A300
fully operational under Linux. I certainly don't want the ATI GPU to
overheat and be plagged by the issues of the current Nvidia's G84 and
G86 based GPUs.

You mentioned that the ACPI tables have to be modified. Do you mean
the DSDT table? What's the entry to be modified?

Regards,
Ilyes Gouta.
