Description:
KTemperature is an application to monitor the system temperature. I was motivated to develop this utility because I could not find a simple system tray resident application for monitoring the system temperature using the ACPI interface.
The application obtains the system temperature from the file /proc/acpi/thermal_zone/THRM/temperature .
I have been using Linux and Open Source for quite sometime and this is my first contribution. I hope this will lead to
many more contributions from me.
SuSE 9.2 rpm for the i686 platform is available for download.
The available rpm also works for SuSE 9.3.
The rpm available for download can be installed on SuSE 10.0 as well.
Changelog:
Version 1.1
Added check for the presence of /proc/acpi/thermal_zone/THRM/temperature file. If the file is not present the temperature will be displayed as NA.
Version 1.2
Corrected typo.
Visual representation of the "hotness" of the system.
The system maximum temperature can be provided as an input. The system tray icon will change redness depending on the ratio of provided maximum temperature to the current temperature.
Version 1.3
Configurable temperature monitoring interface, can be anything as long as the temperature can be obtained by doing a read operation on the file.
Stored configuration. The configuration is stored in $HOME/.ktemperatue and read on startup.
Increased sensitivity of redness to temperature changes.
Version 1.4
Auto adjusting text font. The color of the text adjusts to a compliment of the background color, This ensures that the text is clearly visible irrespective of the redness of the systray icon.
More prominent text. The text is bold faced and the font of the text is bigger.
Version 1.5
Changes of parameters (polling interval and max, temperature) take instantaneous effect without having to restart the application.
Boundary values cases of redness, the calculation of redness difference between the background and the foreground has been modified to ensure a minimum difference.
Text alignment, the temperature text will be aligned in the middle both vertically and horizontally.
Version 1.6
Auto loading of the neccessary ACPI thermal module and its dependencies if, required. The root password is checked prior to loading the modules.
Detection of two variants of the thermal interface, namely
/proc/acpi/thermal_zone/THRM and
/proc/acpi/thermal_zone/THM
Version 1.7
The ACPI thermal interface was being detected by searching the /proc/modules file. However, that approach will lead to an irritating request for root password in cases where the module in compiled into the kernel. The thermal interface detection has been modified to take care of the above case.
Version 1.8
Added Pause, Restart and Update options in the right click menu for more control of polling.
Cleaned the auto detection of ACPI thermal interface. The first file in the thermal_zone directory(other than .. and .)is taken as the temperature file.
Fixed the width of the main window to be always greater than the width of widest child window.
Version 1.9
Changed the implementation of 'redness' from RGB space to HSV space for greater sensitivity.
The background color changes from green at minimum temperature to red at maximum temperature.
The text is always constant and will have a clear contrast all temperatures.
Replace memcpy with strcpy in monitor interface selection.
Interface(s) selected in the drop down list will be honoured when the Set button is clicked after the selection.
Used grid layout for the main widget.
Version 1.9-1
Created archive to include version information.
Added keyboard shortcuts to right click menu options.
Added caption to root password dialog.
I would like to acknowledge the suggestions that I have received. The changes have been made taking into account these suggestions.
