Description of problem: everytime i start powertop it complains like this: Loaded 75 prior measurements Cannot load from file /var/cache/powertop/saved_parameters.powertop i checked the file. its there but it isnt. ll /var/cache/powertop/saved_parameters.powertop ls: cannot access /var/cache/powertop/saved_parameters.powertop: No such file or directory [root@laptop powertop]# cd /var/cache/powertop/ [root@laptop powertop]# ll total 92K -rw-r--r-- 1 root root 92K Apr 19 19:47 saved_results.powertop and drwx------ 2 root root 4.0K Apr 19 19:00 powertop Version-Release number of selected component (if applicable): 1.97 How reproducible: everytime Steps to Reproduce: 1.start powertop 2.quit to view full error message 3. Actual results: no idea if it is harmful to the program Expected results: no error messages Additional info:
ok - so the file is missing - why is powertop asking for a non-existent file ?
I have the problem too.
It seems you didn't run the initial calibration. If you are running on NB, disconnect AC and run: # powertop --calibrate Then let the powertop to collect enough data (approx. 1 hour). After then it will show approx. wattage for each process / device. When you exit, it saves its state and the message should gone. It is only warning and it should be ignored, if it annoy you and you can't/don't want to run the calibration just: # touch /var/cache/powertop/saved_parameters.powertop Maybe the wording of the message is a bit confusing, I will forward this to upstream.
