questions on usage and a few errors

[kmkramer]

I just installed this from the release ISO after borking my 18.04 LTS Desktop trying to install Nvidia drivers. a few issues and questions.

1. I'm getting this on the powertop --auto-tune

modprobe cpufreq_stats failedLoaded 0 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 Using PowerCap Sysfs : Domain Mask f
Devfreq not enabled
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

2. also seeing these in syslog, which resemble the issues I had on 18.04

usb 1-9: new full-speed USB device number 30 using xhci_hcd
usb 1-9: Device not responding to setup address.
usb 1-9: Device not responding to setup address.
usb 1-9: device not accepting address 30, error -71
usb 1-9: new full-speed USB device number 31 using xhci_hcd
usb 1-9: Device not responding to setup address.
usb 1-9: Device not responding to setup address.
usb 1-9: device not accepting address 31, error -71
usb usb1-port9: unable to enumerate USB device

I noticed after initial install was using Intel, ran sudo prime-select nvidia, logged out and could not log back in. Had to restart completely to get desktop and nvidia was indeed loaded. Should a logout be sufficient?

Am I to continue to apt update; apt upgrade using this install? Seems like that opens you up to breakage since you have customized all the drivers and kernel.

sudo apt list --upgradable

What system are on on now? 17.10 or 18.04?

I have uploaded an experimental 18.04 ISO that is already outdated. I need to push a new one with the latest fixes and discoveries.

17.10, let me know if you want me to try something. I haven't updated this install at all...
