description |
I installed the Kubuntu variant of Ubuntu 18.04 on a new HP Spectre 13 laptop. Performance is poor. The CPU (an i7-8550U) is running at 400MHz, and never speeds up, even when running some of the Phoronix Test Suite benchmarks.
I can use cpupower to switch to the "performance" cpufreq governor, but cannot change the frequency with either governor.
Here is the output of some experiments I ran while Phoronix's c-ray test was running.

The governor "powersave" may decide which speed to use
within this range.

- Do you have proper administration rights? (super-user?)
- Is the governor you requested available and modprobed?
- Trying to set an invalid policy?
- Trying to set a specific frequency, but userspace governor is not available,
for example because of hardware which cannot be set to a specific frequency
or because the userspace governor isn't loaded?
