rtop

rtop is a performance monitor designed for the Rockchip RK3566/68/88 processors.

rtop for Ubuntu OS by Joshua Riek.

Specifically built for Rockchip processors using Qt5 by Q-engineering

If you have the original Rock OS, please install https://github.com/Qengineering/rtop-KDE

Installing rtop.

To install rtop, download the repository, make the install script executable, and run it:

$ git clone https://github.com/Qengineering/rtop-Ubuntu.git rtop
$ cd rtop
$ sudo chmod +x ./install_rtop.sh 
$ sudo ./install_rtop.sh 

If your system complains about missing the libQt5Widgets.so.5 library, you can install it with the next command:

sudo apt-get install libqt5widgets5

Running rtop.

To run rtop from the command line in the terminal:

$ rtop

Alternatively, you can use the shortcut available in your software overview.



You can also make rtop a favorite.

Permissions.

As noted in the appendix, some information requires sudo permissions.
The installation script should handle this automatically.

If you don't see RGA bars, it could indicate a permissions issue.
To resolve this, try running rtop with sudo:

$ sudo /usr/local/bin/rtop

Alternatively, you can disable the password prompt globally using sudo visudo.

If the NPU bars are not visible, ensure the NPU is enabled by following the commands provided in the appendix.

Qt5.

For your convenience, the Qt5 code is included.
