To activate Live GPS tracking in QGIS you need to select Settings ‣ Panels GPS information. You will get a new docked window on the left side of the canvas.
There are 4 possible screens in this GPS tracking window:
With a plugged in GPS receiver (has to be supported by your operating system) a simple click on [Connect] connects the GPS to QGIS. A second click (now on [Disconnect]) disconnects the GPS-receiver from your computer. For GNU/Linux gpsd support is integrated to support connection to most GPS receivers. Therefore you first have to configure gpsd properly to connect QGIS to it.
If you want to record your position to the canvas you have to create a new vector layer first and switch it to editable status to be able to record your track.
