Still no picture on screen :( root@beagleboard:~# dmesg | grep -i fb .init : 0xc07a9000 - 0xc07fb040 ( 329 kB) [ 3.830474] Freeing unused kernel memory: 328K (c07a9000 - c07fb000) [ 10.082489] omapdrm omapdrm.0: fb0: omapdrm frame buffer device root@beagleboard:~# dmesg | grep -i drm [ 3.042266] [drm] Initialized drm 1.1.0 20060810 [ 9.785095] omapdrm omapdrm.0: DMM not available, disable DMM support [ 9.792816] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
