BeagleBone Black Tips && Tricks

Beaglebone X uses framebuffer device, So adding a modeline in xorg.conf won't work. Likewise any fb-resolutions given on the kernelCL depend on that framebuffer-resolution already defined. In the end, none of that is really needed.

Steps: - generate a new fb config, using gtf <width> <height> <refreshrate> -f - add it to /etc/fb.modes - you're done, the rest happens automatically

fb.modes.example

mode "1440x900-60"
    # PCLK: 106.47 MHz, H: 55.92 kHz, V: 60.00 Hz
    geometry 1440 900 1440 900 32
    timings 9392 232 80 28 1 152 3
    hsync low
    vsync high
endmode
