ThinkPad X230 UEFI broken by setting a setting

with 3 comments

Today, I decided to set my X230 back to UEFI-only boot, after having changed that for a bios upgrade recently (to fix a resume bug). I then choose to save the settings and received several error messages telling me that the system ran out of resources (probably storage space for UEFI variables).

I rebooted my machine, and saw no logo appearing. Just something like an underscore on a text console. The system appears to boot normally otherwise, and once the i915 module is loaded (and we’re switching away from UEFI’s Graphical Output Protocol [GOP]) the screen works correctly.

So it seems the GOP broke.

What should I do next?

  1. Solved:

    Matthew Garret pointed me to /sys/firmware/efi/efivars, and then it was obvious: Too many kernel backtraces:
