To set a custom resolution or with modeline

First issue this command on any system to get modeline of your custom resolution, Here i am using 1920×768@60Hz, you can get modelines for your preffered resolutions using the cvt utility

$ cvt 1920 768 60
# 1920x768 59.86 Hz (CVT) hsync: 47.77 kHz; pclk: 120.00 MHz
Modeline "1920x768_60.00"  120.00  1920 2024 2216 2512  768 771 781 798 -hsync +vsync

Then in weston.ini, the following sets the mode with a modeline,

[output]
name=VGA1
mode=120.00  1920 2024 2216 2512  768 771 781 798 -hsync +vsync
