I installed MythBuntu on a working Ubuntu 8.1 distro. I have an Asus M3A78 (AMD) motherboard, outputting HDMI video at 1360x768 to a Vizio VW26L HDTV. I am running AMD proprietary drivers.
I can run mythfrontend in a -window, but not in -no-window mode.
mythtv must be trying a display mode that video hardware or tv can't handle. There must be a config file somewhere? Any ideas?
