Here may be some news: https://bugs.freedesktop.org/show_bug.cgi?id=23916 With the kernel Version 2.6.34.966 on http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-next/current/ the correct modi of TV-standard are delivered! This were not with the older kernels and is new for me! But my problem isn't solved, yet: The command xrandr --output TV1 --mode PAL_B delivers following: xrandr: cannot find mode PAL_B further: now i get four (4!!) devices! 2 VGA and 2 TV-out! Here the answers of the system of the xrandr command: xrandr --verbose Screen 0: minimum 320 x 200, current 1600 x 900, maximum 4096 x 4096 VGA1 connected 1600x900+0+0 (0x3f) normal (normal left
