Running X with fb on the Jetson TK1, I get a flicker on the monitor from time to time. I don't think I need to do anything to trigger it (such as moving the mouse). It just happens from time to time. I don't have the right X patches for nouveau, so X is using fbdev which I guess means the tegra-drm driver. This is with mainline u-boot (2016.07-rc1) and mainline kernel (4.6). I uploaded a video in which you can see the flicker several times (e.g. at 0:03, 0:16 and 0:28): http://www.cyrius.com/tmp/tk1/ -- Martin Michlmayr http://www.cyrius.com/ -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
