No cpu temperature

[ikenny]

I use cpu: {cpu} mem: {mem} 0:{temp}
But when i pres save i get "{temp} sensor not supported"
Also i tryed 0:{coretemp-isa-0000}, i took it from
ikenny@ikenny-pc:~$ sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +48.0°C (high = +95.0°C, crit = +105.0°C)
Core 2: +51.0°C (high = +95.0°C, crit = +105.0°C)

but in second case i got in panel 0:coretemp-isa-0000

I run ubuntu 12.04 with gnome session fallback.
Could someone tell where the problem is?
