When Your Budget Laptop Needs a Custom Kernel: A Linux Troubleshooting Adventure - Andrei Pokhilko, Komodor
Monday May 18, 2026 1:30pm - 2:10pm CDT
205C+D (Level Two)
This talk chronicles my journey of troubleshooting a Linux kernel issue on a budget Intel GeminiLake-based Chinese mini-laptop. What began as a simple hardware purchase escalated into a two-month deep dive into the i915 GPU driver when the display mysteriously went blank during initialization.

I'll walk through the systematic troubleshooting approach: isolating the issue to the i915 driver, identifying the kernel configuration options triggering the problem, and developing a practical patch that bypasses problematic GPIO pin activation sequences. Along the way, I'll share surprising discoveries about hardware compatibility, kernel development complexity, and the limitations of AI tools when facing real-world Linux challenges.

This presentation is designed for Linux enthusiasts and IT professionals curious about kernel troubleshooting. Attendees will leave with practical knowledge about GPU driver internals, confidence that such issues are solvable without specialized expertise, and inspiration to tackle their own hardware compatibility challenges.
