This problem first occurred 1 year ago on Maverick Meerkat. I just upgraded and now it has appeared again. I cannot get the indicator-cpufreq to start either. I added the ignore_ppc = 1 to the grub but whilst that fixed it in Meerkat, it does not in Ocelot. j@j-Inspiron-9300:~$ cpufreq-info cpufrequtils 007: cpufreq-info (C) Dominik Brodowski 2004-2009 Report errors and bugs to [email]cpufreq@xxxxxxxxxxxxxxx[/email], please. analyzing CPU 0: driver: p4-clockmod CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.00 ms. hardware limits: 75.0 MHz - 600 MHz available frequency steps: 75.0 MHz, 150 MHz, 225 MHz, 300 MHz, 375 MHz, 450 MHz, 525 MHz, 600 MHz available cpufreq governors: conservative, ondemand, userspace, powersave, performance current policy: f[B]requency should be within 75.0 MHz and 600 MHz.[/B] The governor "performance" may decide which speed to use within this range. current CPU frequency is 600 MHz. cpufreq stats: 75.0 MHz:0.00%, 150 MHz:0.00%, 225 MHz:0.00%, 300 MHz:0.00%, 375 MHz:0.00%, 450 MHz:0.00%, 525 MHz:0.00%, 600 MHz:100.00% (arg: 2) jason@Inspiron-9300:~$ indicator-cpufreq Traceback (most recent call last): File "/usr/bin/indicator-cpufreq", line 81, in <module> ind = MyIndicator() File "/usr/lib/python2.7/dist-packages/indicator_cpufreq/indicator.py", line 95, in __init__ self.update_ui() File "/usr/lib/python2.7/dist-packages/indicator_cpufreq/indicator.py", line 106, in update_ui fmin, fmax, governor = cpufreq.get_policy(self.cpus[0]) File "/usr/lib/python2.7/dist-packages/indicator_cpufreq/cpufreq.py", line 143, in get_policy policy = (p.contents.min, p.contents.max, p.contents.governor) ValueError: NULL pointer access jason@Inspiron-9300:~$ sudo /etc/init.d/cpufrequtils start * CPUFreq Utilities: Setting ondemand CPUFreq governor... * disabled, governor not available...
