As such, please can you repost with only the internal LCD enabled. We can enable the LCD port later once the tegradrm issues are fixed. Thanks. With no HDMI plugged in, I tested Cardhu's LCD and it works fine. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
