INTERACTIVE SETUP WINDOW
- You can enter the setup utility by pressing F2 to view and modify the following interface options:
- General
- This section deals with general interface options. Color support and interface update interval can be modified.
- Devices
- This section deals with the devices display (top of the interface). You can switch the temperature scale to fahrenheit and set the encoder/decoder hiding timer.
- Chart
- This section deals with the line plots (middle of the interface). You can reverse the plot direction and select which metric is being shown in the plots.
- Processes
- This section deals with the process list (bottom of the interface). You can select the sort order, select the metric by which to sort the processes by and select which metric is displayed.

CONFIGURATION FILE
The configuration file follows the XDG Base Directory Specification and is stored at $XDG_CONFIG_HOME/nvtop/interface.ini. The location defaults to $HOME/.config/nvtop/interface.ini if the XDG location is not defined.
Do not edit this file. The file is automatically created or updated upon toggling the interface saving key F12.
The configuration is loaded during program initialization. If no configuration file is present, default options are used.

BUGS
- Some fields are shown as N/A
- Ask AMD or NVIDIA for better support of your hardware!
If your card uses the AMDGPU driver, a more recent kernel might have improved support.
- Compatibility issues
- Does not work with nouveau driver stack and older NVIDIA GPU for the time
being.
Does not work for AMD graphics card using the old radeon driver.
