Hi,
I'm facing from time to time a "blue" screen on my lenovo x230. It happens at least
twice a day and starting annoying me. The screen went black or shows a one color view.
The x230 is running coreboot with native graphics (no vgabios).
My machine is still running when this happens, so I've
ssh access. As a workaround I can suspend and resume to fix the screen for while.
Any idea how I can debug this further or fix this?
Best,
lynxis
Kernel ring buffer shows before going to suspend:
