How to Keep the Linux Kernel Updated in TUXEDO OS: Complete Guide

This guide explains the theoretical concept behind the Linux kernel management strategy adopted by TUXEDO Computers for its Debian Testing-based TUXEDO OS distribution. This approach is useful for users and developers who want to understand how TUXEDO maintains and optimizes the Linux kernel for its systems.

TUXEDO's strategy is particularly relevant for those using or planning to use TUXEDO OS, as it directly affects hardware compatibility, performance, and system stability. Additionally, it is useful for those interested in Debian Testing-based Linux distributions that follow the latest stable versions of the Linux kernel.

• End Users: For those who want a system optimized for TUXEDO hardware with continuous updates.
• Developers: For those who want to understand how TUXEDO integrates kernel changes and manages updates.
• Linux Enthusiasts: For those interested in Debian Testing-based distributions and their kernel management strategies.

Prerequisites

• Hardware: A TUXEDO Computers computer
• Software: Debian Testing-based TUXEDO OS
• Additional Software: tuxedo-drivers package

Procedure: How TUXEDO Computers Will Maintain the Linux Kernel in TUXEDO OS

By the end of this guide, you will understand the strategy adopted by TUXEDO Computers to maintain the Linux kernel in the new Debian Testing-based distribution.

• Step 1: Identify the kernel base.
• Step 2: Apply TUXEDO patches and configurations.
• Step 3: Understand current patches.
• Step 4: Analyze patches to fix bugs.
• Step 5: Keep drivers separate.
• Step 6: Understand the benefits of continuous updates.
• Step 7: Discover the LTS kernel option.
• Step 8: Dive deeper with the official announcement.

Verification and Troubleshooting

By the end of this guide, you will be able to test the functionality of the Debian Testing-based TUXEDO OS kernel and resolve any issues.

Functionality Test

• Check the kernel version: Open a terminal and type the command uname -r. This will show you the currently used kernel version.
• Check hardware drivers: Run the command lsmod | grep tuxedo to verify that the TUXEDO drivers are loaded correctly.
• Test hardware compatibility: Verify that the display backlight works correctly, especially if you are using a TUXEDO notebook. Also, check for any sudden reset issues on Intel-based InfinityBook Pro Gen8 systems.
• Check graphics performance: Run a graphics test to ensure there are no issues related to negative V-Blank values in the Intel i915 driver.

Troubleshooting

• Backlight issues: If you encounter backlight issues, make sure you have installed the latest linux-tuxedo kernel. If the problem persists, check the system logs with the command dmesg | grep backlight.
• Sudden resets on InfinityBook Pro Gen8: Verify that your system is updated to the latest kernel version. If the problem continues, consult the system logs with dmesg | grep reset.
• Graphics issues with Intel i915: Check the system logs with dmesg | grep i915 to identify any errors related to the graphics driver.
• Hardware drivers not loaded: If some drivers are not loaded, verify that the tuxedo-drivers package is installed correctly. You can reinstall it with the command sudo apt install --reinstall tuxedo-drivers.

Kernel Options

• LTS Kernel: If you prefer a more conservative update path, you can install the linux-tuxedo-lts kernel. To switch to the LTS kernel, run the following commands:
  • sudo apt install linux-tuxedo-lts
  • sudo update-grub
  • Reboot the system and select the LTS kernel from the GRUB menu.

Educational Summary

• Continuous Updates: Switching to Debian Testing allows for continuous kernel updates, unlike the previous Ubuntu-based model.
• LTS Option: A linux-tuxedo-lts kernel will also be available for those who prefer a more conservative update path.
