When Your Budget Laptop Needs a Custom Kernel: A Linux Troubleshooting Adventure
summary
Budget GeminiLake mini‑laptop needs a custom kernel after the display goes blank during init; isolation pins the failure to the i915 GPU driver and specifically the pin control geminylake option. Over two months, kernels are rebuilt from empty configs (minimal bootable ~727 options), debug logs reveal failing VBT GPIO sequences, and a practical patch bypassing GPIO pin 6 makes the machine boot reliably. Result: usable desktop with no touchpad or sound and sleep/wake broken, showing kernel hack works but hardware sequences remain only partially solved.
