PSensor

Psensor is a graphical hardware monitoring application for Linux.

It draws realtime charts and raises alerts about:

• the temperature of the motherboard and CPU sensors (using lm-sensors).
• the temperature of the NVidia GPUs (using XNVCtrl).
• the temperature of ATI GPUs (using ATI ADL SDK).
• the temperature of the Hard Disk Drives (using hddtemp, libatasmart or udisks2).
• the rotation speed of the fans.
• the temperature of a remote computer.
• the CPU load.

Alerts are using Desktop Notification and a specific GTK+ status icon.

Note

For Ubuntu users, Psensor is providing an Application Indicator which turns red under alert and a menu for quickly check all sensors.

A new feature of PSensor is to allow manual fan speed controlling by writing PWM values to the pwm controllers each asociated to the certain fan managed by the kernel.

This only works with 4 pin based cooling fans!!!

It relies on a simple user interface that lists all available cooling fans inside your computer.

Components:

• Core library
• New Desktop GUI
• GUI Utility (Old)
• Web Server (Old)

Building from source

Installation requirements:

• Xmake

Dependencies

json-c
glib-2.0
libgtop-2.0
gio-unix-2.0
udisks2
libatasmart
X11
libkmod

Build Commands

also check out build configuration for specific fatures: xmake f --menu then enter Project Configuartion

then build: xmake

Note

The GTK based desktop GUI will be removed in the future due to old unmaintained dependencies and code bloatware.

New GUI is currently located in src/new-gui/ and it will serve as the official desktop application of psensor fork

Same goes for the old web server which is currently very unsafe to use in terms of security.

Note

On wayland when running with sudo psensor-ui can fail with ERROR new-gui/ui_entry.cpp:168: Error: SDL_Init(): No available video device

To fix this simply pass the -E flag to sudo : sudo -E psensor-ui

This preserves the environment variables
