How to set display resolution?

Banana Pi SBCs design BPI-M2 Ultra / BPI-M2 Berry(A40i)
1

On BPI M2 Berry with Ubuntu 16.04mate exist only one default option 1280 x 720.

How can I change it? (Answer for Claire from 28.3. is not so much good.)

I tried to modify xorg.conf … no way :frowning:

I tried to modify Xrandr … no way. Result: xrandr: Failed to get size of gamma for output default

cvt:
1240x1080 59.98 Hz (CVT) hsync: 67.18 kHz; pclk: 111.25 MHz Modeline “1240x1080_60.00” 111.25 1240 1320 1448 1656 1080 1083 1093 1120 -hsync +vsync

1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz Modeline “1920x1080_60.00” 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsyn1120 -hsync +vsync

May somebody help me please? I think, it is not only my problem. :confused:

Hello, Please see here: http://wiki.banana-pi.org/M2U/Berry_Image_Map

You could use “bpi-bootsel /usr/lib/u-boot/bananapi/bpi-m2u/BPI_M2U_720P.img.gz” to change display resolution.
