Alpine Linux: Kodi GBM No Input Bug Report

Hey guys, let's dive into a frustrating issue some of us are facing with Kodi on Alpine Linux. Specifically, we're talking about the Kodi-GBM build, where the keyboard and mouse inputs just aren't registering. It's like trying to navigate a ship without a steering wheel! This report aims to shed some light on this bug, providing a clear breakdown of the problem, the expected and actual behaviors, and some steps to reproduce the issue. We'll also explore potential fixes and gather as much information as possible to help the Kodi team get this sorted. So, let's get started and see how we can bring our Kodi installations back to life!

The Bug: No Input Detected

Alright, so the core problem is pretty straightforward: no input from keyboard or mouse is being recognized within Kodi-GBM on Alpine Linux. This essentially renders Kodi unusable because you can't control it! You're stuck staring at the screen, unable to select anything, play anything, or even navigate the menus. It's a real bummer, especially if you're using Alpine Linux as a lightweight and efficient platform for your media center. The user experience is severely hampered, turning what should be a smooth and enjoyable experience into a frustrating standstill. This bug report is crucial because it highlights a fundamental usability issue that needs attention.

It's important to understand the scope of the problem. While kodi-send commands still work, indicating that Kodi itself is running and can receive some form of input, the lack of standard keyboard and mouse functionality suggests a deeper problem with how Kodi-GBM interfaces with the input devices on Alpine Linux. This could be due to issues with input drivers, incorrect configuration, or compatibility problems between Kodi and the Alpine Linux environment. Further investigation is needed to pinpoint the exact cause.

Expected Behavior: Full Input Functionality

Naturally, the expected behavior is simple: full keyboard and mouse input. You should be able to navigate the Kodi interface, select menu items, control playback, and perform all the usual actions with your keyboard and mouse. This is the cornerstone of a functional media center, allowing for seamless control and an enjoyable user experience. Think about it – you should be able to effortlessly browse your media library, adjust the volume, and control the playback of your favorite movies and shows. Without this basic functionality, Kodi is essentially a pretty screen saver.

In a perfect world, when you launch Kodi-GBM on Alpine Linux, your keyboard and mouse would just work. You wouldn't have to fiddle with settings, troubleshoot drivers, or resort to workarounds. It should be a plug-and-play experience. The fact that this isn't happening points to a significant flaw that needs to be addressed. This expected behavior is fundamental to the usability of Kodi, and its absence severely impacts the user experience.

Actual Behavior: Input Unresponsive

What's actually happening is far from ideal. Kodi-GBM simply does not respond to keyboard or mouse input. You move the mouse, and the cursor doesn't budge. You press keys on the keyboard, and nothing happens. It's like the input devices are invisible to Kodi. This leaves the user stranded, unable to interact with the software and enjoy their media. This unresponsive behavior is a key indicator of the underlying issue, and understanding why this is happening is crucial for finding a solution. The lack of input makes Kodi essentially unusable, preventing the user from enjoying their media content.

The fact that kodi-send still works complicates the situation a bit. This indicates that Kodi itself is running and can receive commands, but the standard input methods (keyboard and mouse) are not functioning. This suggests that the problem lies specifically in how Kodi-GBM handles input from these devices within the Alpine Linux environment. The debug log is essential here, providing a detailed record of Kodi's activities, including how it attempts to initialize and handle input devices. This information is invaluable for identifying the root cause of the problem.

Possible Fixes: Investigating Potential Solutions

While we don't have a definitive fix yet, let's brainstorm some possible solutions or areas to investigate. This isn't a comprehensive list, but rather a starting point for troubleshooting:

• Input Driver Issues: The problem could stem from issues with the input drivers on Alpine Linux. Kodi might not be correctly recognizing or initializing the keyboard and mouse drivers. Verify that the necessary input drivers are installed and functioning correctly within Alpine Linux.
• Configuration Problems: There might be misconfigurations in Kodi's settings related to input devices. Review Kodi's input settings, ensuring that the correct input devices are selected and configured properly.
• Compatibility Issues: Compatibility problems between Kodi-GBM and the specific version of Alpine Linux or the kernel could be the culprit. Ensure that you are using a compatible version of Kodi-GBM with your Alpine Linux setup.
• GBM-Specific Issues: Since this is a Kodi-GBM build, there might be issues specific to the GBM (Generic Buffer Management) backend. GBM handles graphics and input, so problems here could directly affect input handling. Check for known issues or workarounds related to GBM on Alpine Linux.
• Dependency Problems: Missing or incorrect dependencies could be interfering with Kodi's ability to recognize input devices. Make sure all required dependencies for Kodi-GBM are installed and up-to-date.
• Permissions Issues: It's possible that Kodi doesn't have the necessary permissions to access the input devices. Verify that the Kodi user has the appropriate permissions to access the keyboard and mouse devices.

These are just some areas to explore. The key is to systematically investigate each possibility, starting with the simplest solutions and working our way up to more complex troubleshooting steps.

Steps to Reproduce the Issue: A Clear Guide

To make it easy for others to reproduce the bug and verify the fix, here's a detailed set of steps:

1. Clean Alpine Installation: Start with a fresh installation of Alpine Linux. This ensures a clean baseline and minimizes the chances of conflicts with existing software.
2. Add Edge/Testing Repos: Add the edge and testing repositories to your Alpine Linux configuration. This gives you access to the latest packages, including the most recent Kodi-GBM builds.
3. Install Kodi-GBM: Use the apk add kodi-gbm command to install Kodi-GBM. This installs the necessary packages for Kodi with the GBM backend.
4. Run Kodi-GBM with Debugging: Run Kodi-GBM from the command line with the --logging=console flag. This will provide detailed debugging information in the console, which is crucial for troubleshooting.

These steps create a reliable method for replicating the problem. By following these steps, other users and developers can easily test the bug and help find a solution. The goal is to make it as simple as possible for others to experience and understand the problem.

Debuglog: Essential Information

The debuglog is a critical piece of the puzzle. It contains detailed information about Kodi's operations, including any errors or warnings related to input devices. This log provides valuable insights into what's happening behind the scenes, allowing developers to identify the root cause of the problem. When submitting a bug report, always include a debuglog. This is absolutely mandatory for assisting the team in solving the problem.

The debuglog should be created while running Kodi-GBM from the command line with the --logging=console flag. This will output the debug information to the console, and you can then copy and paste the relevant sections into your bug report. Make sure to include the entire log, or at least the section from when Kodi starts up and attempts to initialize input devices.

Screenshots: Visual Aids

While not always necessary, screenshots can be helpful for illustrating the problem. In this case, screenshots might not be the most effective way to show the lack of input, but they can be useful for demonstrating the Kodi interface itself or any error messages. If there are any relevant error messages or unusual behavior, a screenshot can provide valuable context.

If you have any visual aids, include them in your bug report. These are supplementary and are not the primary means of presenting your report, but they help to clarify what happens in your system.
