Ultrawide Display for Ubuntu Mate DE - dudeytsang - 12-31-2016
Is this possible? Trying to use a 21:9 monitor (2560x1080p60). The only resolution open is standard 1080p resolution.

You can try to define the resolution and timings in X using CVT and xrandr. It's been a long time since I did this, but you can try what's mentioned in this post:
http://askubuntu.com/questions/377937/how-to-set-a-custom-resolution
Put in whichever width, height and refreshrate you want in CVT and use the commands that follow on xrandr. I have no guarantee this will work on the A64 SoC, so good luck.
Should it work, post your results in the thread as it will be great for other users.

First generate a "modeline" by using cvt
Syntax is: cvt width height refreshrate
Code:
cvt 1680 1050 60this gives you:
Code:
# 1680x1050 59.95 Hz (CVT 1.76MA) hsync: 65.29 kHz; pclk: 146.25 MHz
Modeline "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsyncNow tell this to xrandr:
Code:
sudo xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsyncThen you can now add it to the table of possible resolutions of an output of your choice:
Code:
sudo xrandr --addmode VGA-0 1680x1050_60.00
