[Manjaro KDE] Missing Dell Thermal Management feature after system update

[zburgermeiszter]

Hi,

I'm using Manjaro linux, and until recently this Plasma widget has worked properly but after an update the Thermal Management feature has gone missing.

Do you have any idea what should I check or reinstall?

AFAIK it relies on the libsmbios package which I already removed and reinstalled without any success to get the Thermal Management back.

Thanks.

Do you still have smbios-thermal-ctl executable installed?

[zburgermeiszter]

Yes.

can you run the following and provide me the output?

sudo /usr/share/plasma/plasmoids/gr.ictpro.jsalatas.plasma.pstate/contents/code/set_prefs.sh -read-all

it shouldn't ask you for a sudo password

[zburgermeiszter]

That's correct, it did not ask for sudo password.

The output is:

{
  "cpu_min_perf": "9",
  "cpu_max_perf": "100",
  "cpu_turbo": "true",
  "gpu_min_freq": "300",
  "gpu_max_freq": "1150",
  "gpu_min_limit": "300",
  "gpu_max_limit": "1150",
  "gpu_boost_freq": "1150",
  "gpu_cur_freq": "1017",
  "cpu_governor": "powersave",
  "energy_perf": "balance_performance",
  "thermal_mode": "cool-bottom"
}

I just found the issue #3 , which mentions an issue with $LC_ALL. Apparently that is not configured properly. When I open a new terminal I get the following error:

manpath: can't set the locale; make sure $LC_* and $LANG are correct

Does it affect the pstate plugin's ability to manage thermals?

[jsalatas]

can you try the proposed solution?

https://github.com/jsalatas/plasma-pstate/issues/3#issuecomment-451703114

it is probably the same issue (locale related)

[zburgermeiszter]

Fixing the $LC_ALL issue automatically fixed the pstate widget.

Instead of hacking the script, I fixed the $LC_ALL globally. Here is the solution: https://forum.manjaro.org/t/default-locale-not-set-properly/64163/28

sudo echo $LC_ALL is still empty, but I can't see the locale error anymore in my terminal and the plugin is working properly again.

Thanks for your help.

Closing the issue now.
