Fix Ubuntu Desktop to Boot without Monitor Connected
From Bonus Bits
This article gives the steps to be able to boot Ubuntu Desktop on hardware without needed a monitor connected.
- Won't boot at all
- When VNC / Screen Share into the box everything is VERY VERY slow. Even to login.
- Ubuntu Desktop 14/15/16/17
- Unity Desktop (Not sure if fix works for Gnome)
Install Video Dummy Package
- SSH into the system
- If you didn't get sshd setup already, then hook up a monitor and get it setup. Could just do the fix while connected direct or remote using CLI.
- Install xserver-xorg-video-dummy
sudo apt-get install xserver-xorg-video-dummy
Create Default X Windows Configuration File
- Create / Edit xorg.conf file
- Rename file if already exists for backup
sudo vi /usr/share/X11/xorg.conf.d/xorg.conf
- Add the following content to the file
- Set the resolution to what you like (whatever resolution the screen is that is used to connect remotely is probably is a good idea)
Section "Device" Identifier "Configured Video Device" Driver "dummy" EndSection Section "Monitor" Identifier "Configured Monitor" HorizSync 31.5-48.5 VertRefresh 50-70 EndSection Section "Screen" Identifier "Default Screen" Monitor "Configured Monitor" Device "Configured Video Device" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1920x1080" EndSubSection EndSection
- Save the file
