conflict drivers nvidia nouveau blacklist missing XPS 9570

I used it because of this:

powertop --auto-tune

modprobe cpufreq_stats failedLoaded 49 prior measurements
Cannot load from file /var/cache/powertop/saved_parameters.powertop
File will be loaded after taking minimum number of measurement(s) with battery only
RAPL device for cpu 0
RAPL Using PowerCap Sysfs : Domain Mask f
RAPL device for cpu 0

Cannot load from file /var/cache/powertop/saved_parameters.powertop
File will be loaded after taking minimum number of measurement(s) with battery only

Leaving PowerTOP

i get the same error, it doesnt hinder the function of auto tune setting all pci devices to "Auto" so they are more efficient.

~ >>> sudo powertop --auto-tune

you dont need to run --configure , just leave powertop running while the computer is on battery power and after it takes "329" measurements it will provide more accurate info. if you watch the number you will notice it getting lower and lower for each measurement it takes (while on battery power)
