I've just tried this (the HBi1 was booted previously with the HDMI socket disconnected). Just now, I turned the TV on, and then connected it to the HDMI. The TV reported a resolution of 1024x768, and the kernel log was silent. My guess would be that your HDMI sink is reporting slightly non-standard 1024x768 timings, which cause the IPU restrictions to be violated. Maybe dumping the EDID of the HDMI device would reveal this? # edid-decode < /sys/class/drm/card0-HDMI-A-1/edid might provide some hints? -- FTTC broadband for 0.8mile line: currently at 10.5Mbps down 400kbps up according to speedtest.net. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
