I am new to Linux and having minor issues. I followed this guide initially, but did not receive the proper output, and it did not show my ATI Radeon HD 5000 temperature or fan speed. Then I used this guide, and the same problems were exhibited. I had no issues installing it and no errors. I think it's not reading i2c for some reason. The proprietary driver is installed and functioning correctly according to fglrxinfo. I can use aticonfig commands and view both the temperature and fan. Thoughts?

Any ideas on how to get it working under sensors?

When I run sudo sensors-detect this is my output

# sensors-detect revision 5984 (2011-07-10 21:22:53 +0200)
# System: LENOVO IdeaPad Y560 (laptop)

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): y

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): y
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No

Probing for `Winbond W83782D' at 0x290...                   No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): y
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 3400/5 Series (PCH)

Now follows a summary of the probes I have just done.
Just press ENTER to continue: 

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

To load everything that is needed, add this to /etc/modules:
#----cut here----
# Chip drivers
coretemp
#----cut here----
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!

Do you want to add these lines automatically to /etc/modules? (yes/NO)

My output for sensors is:

acpitz-virtual-0
Adapter: Virtual device
temp1:        +58.0°C  (crit = +100.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +56.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:       +57.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:       +58.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:       +57.0°C  (high = +84.0°C, crit = +100.0°C)

and my /etc/modules is:

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

Have you installed i2c-devel or i2c-tools? If not, install one or the other, whichever is available in your distribution's repositories, reboot, then try sensors-detect again. If it still doesn't work, try the open source drivers that come with your distribution, reboot, and try again.

P.S.: When you post a question, proper form is to state your computer's hardware in full (not just one component of it), and the specific OS you are on (Mageia? Arch? Fedora? Windows? What? What version of it? I understand this to be Ubuntu, but which version?), the exact driver you are on for the problem you are having (which file installed it? Where did you get it?), and what exactly you have tried so far to get things to work for you.

AFAIK, lm-sensors can't read the fglrx fan and temperature, the module only support the reading of this values via the aticonfig with command like this:

aticonfig --pplib-cmd "get temperature 0"
aticonfig --od-gettemperature
