First, are you sure the option is being passed to the kernel? What does "cat /proc/cmdline" return? Second, have you tried the 'e' flag while also specifying a resolution? Try something like: kms_force_mode=video=HDMI-A-1:1024x768@60e ...in /boot/uboot/uEnv.txt. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
