GAI-Temp
gai-temp is an applet that allows you to display the temperature of your harddisk and your cpu.
In order to do this, gai-temp needs access to hddtemp [1] deamon (to display the harddisk temperature) and a properly working lm_sensor installation. The cpu temperature can also be read from acpi, what most modern mainboards should support. Therefore your kernel has to support "ACPI thermal zones" (CONFIG_ACPI_THERMAL)
- hddtemp daemon
The hddtemp daemon should be listening on localhost:7634 Your harddisk must have a temperature sensor and the S.M.A.R.T. option must be enabled in the bios setup. In order to get more information about this, have a look at [1].
- acpi
The temperature is read from "/proc/acpi/thermal_zone/THRM/temperature" If there is no such file, either your kernel doesn't support this feature (load the corresponding module - thermal ) or your mainboard doesn't support it.
- lm sensors
There is only support for kernel 2.6 atm.. If you have an older kernel you could try to find out if you can read the temperature from the sys filesystem (/sys/*) or the proc filesystem (/proc/*) and mail the result to me.
On linux-2.6 the temperature is read from /sys/devices/platform/i2c???.
Every sensor is displayed by default. You can change this by right-clicking the applet and choosing preferences. If you only see the "common"-tab, no sensors where found. The sad-looking face also shows you this ;-)
If you have any problems with - or comments on gai-temp, don't dare to send an mail to me (Olaf Leidinger <leidola@web.de>)
