How to setup Zaphode mode in Ubuntu

Black_G3

Hello,

We are having issue to setup Zaphod mode in Ubuntu.
UP Square board with BIOS 2.1
Ubuntu 16.04 and 18.04 with built-in X server and Intel driver (no change)

/etc/xorg.conf
ection "ServerLayout"
Identifier "Layout0"
Screen "Screen0" 0 0
Screen "Screen1" RightOf "Screen0"
EndSection

Section "Device"
Identifier "Device0"
Driver "intel"
BusID "0:2:0"
Option "ZaphodHeads" "DP1"
Option "AccelMethod" "sna"
Screen 0
EndSection

Section "Device"
Identifier "Device1"
Driver "intel"
BusID "0:2:0"
Option "ZaphodHeads" "HDMI1"
Option "AccelMethod" "sna"
Screen 1
EndSection

Section "Monitor"
Identifier "DP Monitor"
Option "PreferredMode" "1920x1080"
EndSection

Section "Monitor"
Identifier "HDMI Monitor"
Option "PreferredMode" "1920x1080"
EndSection

Section "Screen"

Monitor "DP Monitor"
DefaultDepth 24
Device "Device0"
EndSection

Section "Screen"

After boot into Ubuntu, only DP has screen. HDMI is blank. Tried DISPLAY=:0.1 firefox& saw firefox on HDMI but it is not responding to any mouse click. We also see rendering issue and screen flickering.

Can some one help us setting up Zaphod mode? Thanks

Hi @Black_G3 ,

I just tested my UP2 board (64 GB), BIOS 3.3
Ubuntu 16.04 with UPboard kernel
https://wiki.up-community.org/Ubuntu#Install_Ubuntu_kernel_for_UP_from_PPA

Two different monitors connected to HDMI and DP (using HDMI-DP adapter).

They are working correctly simultaneously.

Try to install the latest BIOS for UP2:
