I did login blindly on tty2 and started xfce using the open tegra driver, but still no hdmi output. I can send you the Xorg log file if you want to. Xfce seems to run correctly, as far as I can see all necessary processes are running. The monitor I connect to the hdmi is an dvi monitor using an dvi to hdmi adapter, so no sound is connected. But that shouldn't be a problem. > > Thierry -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
