Using TeamViewer on headless (without monitor) ubuntu machine
In order to get TeamViewer running smoothly (without lag, or simply cannot install) when no monitors are connected, you need to emulate one. This is done by creating (or editing) this file : /usr/share/X11/xorg.conf.d/xorg.conf And add the following content : 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 "1024x800" EndSubSection EndSection Reboot the computer #1
