Thanks for testing. At least my code seems right now, but I still cannot get it to work on my machine. The output of modetest is: https://gist.github.com/1365083 There is only one connected connector+encoder+mode so I don't know where the problem exactly is. Are there any debug options? Is it possible to query the EGLImage for width/height? > -- > Jesse Barnes, Intel Open Source Technology Center > Cheers David _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
