upboard headless resolution

Vladislav · July 2017

Hi everybody!

How to set default resolution when boot headless?
I want to use it with x11vnc.

Also, when I boot up board without connected hdmi monitor I am not able to switch it on after boot.

Any ideas??

Hi Vlad,

What BIOS version is available on your board? Please make sure you use the latest version available: https://up-community.org/downloads/download/18-uefi_bios/5-upc1bm0x_efi

Also what Operating system are you using (and what kernel version, if Linux)?

I use Ubilinux 3.0 and recent version of bios

This should work:

cat <<EOF >/etc/X11/xorg.conf
Section "Device"
       Identifier      "Default Device"
       Option  "NoLogo"        "True"
EndSection

Section "Monitor"
   Identifier    "Configured Monitor"
EndSection

Section "Screen"
   Identifier    "Default Screen"
   Monitor        "Configured Monitor"
   Device        "Default Device"
   SubSection "Display"
       Depth    24
       Virtual 1280 720
   EndSubSection
EndSection
EOF
sudo chmod 644 /etc/X11/xorg.conf

Change the 1280 720 to whatever resolution you want to use.

WereCatf, it does not help, resolution is still 1024x768

Any other ideas??
I still have 1024x768 which is too small for my project...

I tried several options and this one helps:
xrandr --fb 1920x1080

Thanks!
