Subject: no /proc/acpi/fan on Fujitsu ST5032D
Date: Mon, 11 Sep 2006 08:48:27 +0800 [thread overview]
Message-ID: <4504B25B.8060800@yahoo.com> (raw)
A new Gentoo install from 2006.1 Live. I've installed the latest
'gentoo-sources', compiled and it boots ok.
Neither the liveCD nor the new kernels show any entries at all in
/proc/acpi/fan or /proc/acpi/thermal.
Other acpi entries are present.
I have tried every distro's live CD I can find - same results. Full
installs of Kubuntu Dapper 6.06 the same. I could read CPU speed and
battery, but the thermal stuff doesn't exist. The machine gets hot, and
I can't risk Linux on it until the fan turns on. It never does.
Hardware is a Fujitsu Stylistic ST5032D tablet:
1.2G Centrino ULV
Intel 915 video
2G RAM
Native OS is XP Pro TabletPC, and the fan runs properly with that OS, so
I know it works.
I get the same behavior with a Fujitsu ST3400s tablet with Xubuntu
(didn't test with XP - I mean the same symptoms with Linux - no fan, no
entries). However, the thermal zone & temperature do appear on the ST3400s.
The default LiveCD kernel has all the ACPI stuff, I load the modules by
hand, the new kernel has ACPI entries, the same, no devices, no fan, no
temperatures.
Help please? I would like to get on with making tablets usable with Linux.
Thanks,
Bret
