Comment 4 for bug 356208

Sebastien and I exchanged email over this bug and he requested that I check with Jaunty which I did. The applet appeared to work and I sent him email about it.

I have reinstalled Jaunty on the same machine (Dell D630) and the applet has stopped working again. This time I have changed this report to a question rather than a bug and I would like to understand what is not working. Any help in debugging would be most appreciated.

What I find now is as follows.

apt-cache policy gnome-applets

ls -l /usr/bin/cpufreq-selector
-rwsr-sr-x 1 root root 30656 2009-04-23 08:28 /usr/bin/cpufreq-selector

more /proc/cpuinfo

stepping : 13
cpu MHz : 2001.000
cache size : 2048 KB

Using cpufreq-selector from the command line, I (logged in as a user who is NOT root and who CANNOT ADMINISTER the system).

cpufreq-selector -f 800000
more /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6

In other words, I (logged in as amrith, not the root user, not an administrator) am able to use cpufreq-selector to update the scaling. And it works because cpufreq-selector has been setuid'ed correctly.

On the other hand, the CPU performance applet does not give me the ability to change the frequency.

NOTE:

If I login as the root user, the CPU performance applet works correctly.

The difference appears to be that as a non-root user, the CPU Frequency Scaling Monitor applet is not allowing me to adjust the scaling, just view it. But, as a root user, the CPU Frequency Scaling Monitor applet is working correctly.

What have I tried?

1. I tried to suid on /usr/lib/gnome-applets/cpufreq-applet

I can't launch the applet, it gives an error

2. I've tried to strace the applet

When logged in as the non-root user, I see nothing indicating an error.

How should I gather more information to help debug this?
