PBR running hot

[wrzomar]

I've written a simple C++ program to use it with conky.
Here is code:

Code:

#include <iostream>
#include <fstream>
#include <iomanip>
#include <string>

using namespace std;

int main(int argc, char **argv)
{
   ifstream tempFile;
   string zone;
   if(argc == 2){
       zone = argv[1];
   }
   else{
       zone = "0";
   }
   tempFile.open("/sys/class/thermal/thermal_zone"+ zone +"/temp");
   if(!tempFile){
       cout << "--.--- \u00B0C" << endl;
   }
   else{
       int temp;
       tempFile >> temp;
       tempFile.close();
       cout << fixed << setprecision(3) << (temp / 1000.0) << "\u00B0C" << endl;
   }
return 0;
}

Just save it e.g. 'main.cpp', then build it with:

g++ -o pbp_temp_conky main.cpp

If you don't have g++ installed, first run:

sudo apt install g++

Then you can run it without arguments or with 0, 1 or 2.
To use it with conky, first you will need to install it with:

sudo apt install conky

or

sudo apt install conky-all

Copy 'pbp_temp_conky' somewhere within your $PATH, e.g.

sudo cp pbp_temp_conky /usr/local/bin/

Create conky autostart desktop file '~/.config/autostart/conky.desktop' with:

Code:

[Desktop Entry]
Type=Application
Exec=conky -b
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name[en_US]=Conky
Name=Conky
Comment[en_US]=Auto run conky
Comment=Auto run conky.

And copy conky config file from /etc/conky/conky.conf to your home folder and rename it to .conkyrc and customize it to your liking.
Here is mine .conkyrc:

Code:

-- vim: ts=4 sw=4 noet ai cindent syntax=lua

Lines with # are comments. I've commented out ${freq 2} to ${freq 4}, because on PBP they're always the same as ${freq 1}, same is with 5 and 6.
At last start conky with Alt+F2, enter:

conky -b

or re-login.
