int.Reaction Posted July 19, 2015 Share 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? Link to comment Share on other sites More sharing options...
Igor Posted July 19, 2015 Share 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. Link to comment Share on other sites More sharing options...
