Как изменить разрешение экрана в ubuntu 16.04 (совместимый с VGA контроллер: XGI Technology Inc. (eXtreme Graphics Innovation))

Question

Я хочу изменить разрешение экрана на более высокое значение, вот что я попробовал:

1 -

$ cvt 1280 1024

# 1280x1024 59.89 Hz (CVT 1.31M4) hsync: 63.67 kHz; pclk: 109.00 MHz
    Modeline "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

$ sudo xrandr --newmode "1280x1024_60.00"  109.00  1280 1368 1496 1712  1024 1027 1034 1063 -hsync +vsync

xrandr: Failed to get size of gamma for output default

$ xrandr --addmode default "1280x1024_60.00"  
xrandr: Failed to get size of gamma for output default

$ xrandr
