I am running Xubuntu 12.10 in my laptop and I would like to monitor the CPU and HDD temperatures. I have installed lm-sensors, hddtemp and xfce4-sensors-plugin and added the widget into the XFCE panel. Now, when I login or manually run xfce4-sensors in terminal, I get the following notification:
"hddtemp" was not executed correctly, although it is executable. This is most probably due to the disks requiring root privileges to read their temperatures, and "hddtemp" not being setuid root.
An easy but dirty solution is to run "chmod u+s /usr/sbin/hddtemp" as root user and restart this plugin or its panel.
Calling "/usr/sbin/hddtemp -n -q /dev/sda" gave the following error:
/dev/sda: Permission denied
with a return value of 256.
When this happens I do not have any option to show the HDD temperature on the panel. However, if I run gksudo xfce4-sensors and enter the password I get no error and can show the HDD temperature on the pannel if I want to.
Since root permissions are needed in order to run hddtemp and chmod u+s /usr/sbin/hddtemp is not recommended, what alternative do I have to run hddtemp from xfce4-sensors plugin automatically at login?

I had the same Problem after upgrading to 13.04.
I would prefer a non-dirty solution also.
But This bugreport didn't provide any clean solution either
At least: The mentioned dirty solution worked for me:
