I just wanted to suggest you make sure permissions in /dev are granted, but you appear to have arrived at that conclusion yourself. Of course now you have to figure out which device is being opened unsuccessfully. /dev/console only applies to text i/o and not framebuffer and graphics. /dev/fb0 maybe? Maybe use strace instead? cheers! mar77i
