*>You need to comment out the cmdline= line that you're not using. As you can only have one cmdline= statement.*
Yes but the problem is, that this two cmdline was already entry in the orginal. So thats because i have try with two. But anyway my hdmi output is already off also with only one cmdline :-( And concerning /sys/devices, i have verified this not only with the terminal, i could really not found this folder! After lib/firmware/ i could not see any other folder with sys or devices?? Am Dienstag, 21.
