## Selecting a real-time kernel on Ubuntu.
## Selecting a real-time kernel on Ubuntu 24.x
This step is unneccesary on Raspberry Pi OS, which installs an RT_PREEMPT kernel by default.
By default, Ubuntu installs a PREEMT_DYNAMIC kernel, configured to run with volutary preemption. You will need to change this. You can do this by running the following command after you have installed PiPedal:

In order to support real-time audio processing, select Preempt=full.
An RT_PREEMPT kernel provides slightly better realtime audio than a PREEMPT_DYNAMIC/preempt=full kernel, but the PREEMPT_DYNAMIC should be perfectly adequate. If you are having problems with audio dropouts, you may want to try an RT_PREEMPT kernel instead. Ubuntu provides a pre-built RT_PREEMPT kernel; but on our test systems, you can acheive stable low-latency audio using only the PREEMPT_DYNAMIC/preempt=full kernel. The pre-build Ubuntu RT_PREEMPT
kernel is only available if yo have an Ubuntu Pro subscription. But it is relatively easy to build the Ubuntu RT_PREEMPT kernel from source. That is, however, outside the scope of this document. We recommend using the PREEMPT_DYNAMIC/preempt=full Ubuntu kernel.

## Support for WIFI Auto-Hotspots on Ubuntu Server
The following information applies when installing PiPedal on Ubuntu Server 24.0x only. This information does not apply
to Unbuntu Desktop installs or Raspberry Pi OS Lite installs.
PiPedal's Auto-Hotspot feature only works on Linux systems that are using the Network Manager network services stack.
Ubuntu Server 24.x (and probably other server-specific installs on other Debian distros) uses the Netplan network services stack by instead. It does so because the Netplan network stack is the preferred network stack when managing
farms of cloud servers.
It's easy enough to reconfigure Ubuntu Server to run the Network Manager network stack instead. However you should be
aware that Netplan TCP/IP configuration settings will not be migrated to Network Manager. If you perform this step on a server on which changes have beeen madce to Netplan configuration files, you will need to manually migrate those
changes to Network Manager configuration files. On a clean install of Ubuntu Server, this will not be a problem.
To reconfigure Ubuntu Server to use the Network Manager network stack (and therefore enable PiPedal's Auto-Hotspot feature), run the following command:
sudo apt install network-manager

Adjust accordingly depending which package you downloaded.
You MUST use `apt-get`. `apt` will not install downloaded packages; and `dpkg-i` will not install dependencies.
On Raspberry Pi OS, if you have a graphical desktop installed, you can also install the package by double-clicking on the downloaded package in the File Manager.
After installing, follow the instructions in [Configuring PiPedal after Installation](Configuring.md). If
you are using Ubuntu, you will need to reconfigure Ubuntu to use a real-time kernel.
you are using Ubuntu, there are additional post-installation steps you must take to reconfigure the Ubuntu kernel
to provide support for low-latency real-time audio.
