Public bug reported:
Since upgrading to Xubuntu 17.10, this plugin does not show the real
time current frequency, but is locked at (for me) 2.60GHz.
I poked around the source, and the /sys paths that the plugin uses
(specifically "/sys/devices/system/cpu/cpu%i/cpufreq/scaling_cur_freq")
are present and when I cat them, show the current frequency.
The intel_pstate module is present (built into the kernel) and not
disabled in GRUB.
I ran inotifywait over /sys/devices/system/cpu and can verify that the
plugin is reading from the entries there. Output is attached. The
output was captured from when the plugin was added to a panel. It does
not attempt to read scaling_cpu_freq.
