LVDS display in MarshMallow

[redwanmohamed]

Is LVDS display of 800 x 480 resolution tested in i.MX6 Marshmallow release

Am getting a weird behaviour of getting whole android screen in 3/4 of the display and rest of the screen is blank. When i try to screencap the framebuffer it remains the same there as well

Lock screen is exceptional to that behaviour looks perfectly coming in the screen

"screencap -p *.png" is the command used

Any help is highly appreciated

The blankness is nothing but the navigation bar which is not coming not sure about the reason.... i wonder why its coming on the vertical side instead of coming horizontally....disabled navigation bar by setting qemu.hw.mainkeys=1 in build.prop to get the android screen in the whole display

using 3rd party app back button.apk for now instead of navigation bar...wondering why default bar doesnt come with 800x480 resolution. When i was tuning the porch values purposefully kept wrong resolution of 800 x 600 and got navigation bar in the frame buffer not in display (obviously display resolution isnt proper so behaviour is expected in the display)

Tried adding the string from cat /sys/class/graphics/fb0/mode to /system/etc/display_mode_fb0.conf as well

root@sabresd_6dq:/ # cat /sys/class/graphics/fb0/mode
U:800x480p-60
