True. A lot of lines can be cleaned out.

For some reason I keep receiving an error when using
igt_output_override_mode + igt_display calls. The error is
igt-kms-CRITICAL: Failed assertion: drmModeDestroyPropertyBlob(display-
>drm_fd, *blob) == 0
igt-kms-CRITICAL: Last errno: 1, Operation not permitted
Maybe both threads try to access this and this request is not granted?
With drmModeSetCrtc() call I don't see this behavior. Maybe stick with
raw calls instead?
