1.9.1-23

Summary of the problem

There are three intertwined problems with tlp, that look to be caused by changed in the package

1. After installing it, with no other action, the system logs have this (verified on my unstable system)
   This affects all DEs

Feb 05 08:51:14 tlc-xps17-solus tlp[652449]: Error: After the next restart, you won't be able to switch power profiles on the desktop because tlp-pd.service is not enabled --> Invoke 'systemctl enable tlp-pd.service' to ensure the full functionality of TLP.

2. A forum user said that since the sync of 23-Jan that switching power profiles in the Budgie UI didn't change power usage
   I was unable to replicate this on Plasma. After switching power profiles via the power applet, I saw the appropriate scx_loader messages in system logs, and no warnings as below.

I noticed that my laptop was set to performance mode at every boot, and even when switching I could not see a large difference performance/power usage/temperature (unlike before).

They saw this warning

Warning: PLATFORM_PROFILE_ON_AC/BAT is not set because power-profiles-daemon is running.

3. After removing tlp and its dependencies (including linux-tools-x86_energy_perf_policy), the power profile settings were gone

Suspecting tlp (which was updated this week) I decided to remove it (since I was not using it much), along with the dependency.
Now, however, the power profile settings seems to be gone.
They are neither in the Budgie applet, nor in the power section of budgie-control-center.
power-profiles-daemon, however, seems to be installed.

More information

Originally reported in this forum post

Workaround:
Uninstall the daemon itself without uninstalling Budgie desktop when removing it:

sudo eopkg --ignore-dependency rm power-profiles-daemon

Thank you for the summary here.
Just to be clear, the warning was there even before the update (as it should be, it's mentioned in the tlp documentation), it's just that PPD and TLP used to coexist cordially despite it (because I was not using the disabled settings).

2. Might be due to miscunfiguration: I had written a minimal TLP config to change the single setting I needed, but it did not of course take into account the additional functionality which arrived with the update. The default might be better I suppose, which is why it could not be reproduced
