int.Reaction Posted July 19, 2015 Posted July 19, 2015 I've been looking for a way to rotate the display and change the resolution on the Hummingboard running the Debian image I did this from the FAQ: screen resolution: nano /boot/boot.cmd # example: # change example from # disp.screen0_output_mode=1920x1080p60 # to # disp.screen0_output_mode=1280x720p60 mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr somewhat blindly and I destroyed the boot.scr, further searching found that /boot/boot.cmd doesn't exist... I've been messing with xorg with no avail. I think that this is the way to do, through the boot.scr, but there is not any good way to get that running.. The larger question, I guess, is what is the most effective way to rotate the display and change the resolution?
Igor Posted July 19, 2015 Posted July 19, 2015 For default kernel 3.14.x https://github.com/igorpecovnik/lib/blob/next/config/boot-cubox.cmd Others: https://github.com/igorpecovnik/lib/tree/next/config boot*.cmd For rotation try this: Rotation You can rotate the framebuffer by supplying fbcon=rotate:<n> kernel parameter, where n can be one of the following. 0 - normal orientation (0 degree) 1 - clockwise orientation (90 degrees) 2 - upside down orientation (180 degrees) 3 - counterclockwise orientation (270 degrees) This is how it's done on Allwinner. I haven't try this with HB but it might work.
