This is the result:
A terminal with transparent background that shows the temps.
The code to display sensor values and update them two times per second is:
while [ 1 ]; do
sensors; # Outputs cpu and motherboard temps
aticonfig --odgt; # Outputs my AMD GPU temps.
sleep 0.5; # Delay for 0.5 seconds
Save it somewhere as .sh and give execution permissions.
To run the code above (or any other you want) in a terminal:
gnome-terminal --profile=cristal --zoom=0.85 --geometry=60x16+1920+0 -x PATH
I've set previously a new profile of gnome-terminal (called "cristal") that has transparent background and "Temperaturas" as window label.
Then, using the --profile option I set that profile for the new terminal.
The option --zoom=0.85 reduces the terminal size at 85% (genius)
The parameter --geometry is more interesting:
Columns x Lines + Xposition + Yposition
The position is given by your screen resolution. On my screen, the window is in the upper right corner when X = 1920 and Y=0
And finally, PATH is the absolute path to the code you want to execute.
To execute at startup, go to "startup applications", add a new application and where it says "command", paste the line that starts "gnome-terminal --profile......" customized to suit your particulad needs.
Save it and you are done.
