How to get Sikuli working in headless mode

Question

If we have a headless test server running sikuli (both ubuntu and windows configurations needed), how to get it work without a physical monitor and preferably for as many screen resolutions as possible.

Answer 1

I successfully got sikuli running in headless mode (no physical monitor connected)

Ubuntu: check Xvfb.

Windows: install display driver on the machine (to be headless) from virtualbox guest additions display drivers and use TightVNC to remotely set resolution from another machine.

Detailed steps for windows 7

Assume that:

1. Machine A: to be headless machine, windows 7, with vnc server ready (e.g. TightVNC server installed and waiting for connections).
2. Machine B: will be used to remotely setup the virtual display driver on machine A.

steps:

1. Download virtualbox guest additions iso file on Machine A from here (for latest version check latest version here and download VBoxGuestAdditions_x.y.z.iso)
2. Extract iso file (possibly with winrar) into a directory (let us call it folder D)
3. using command prompt cd to D folder

4. Driver extraction

   -To extract the 32-bit drivers to "C:\Drivers", do the following:

   • VBoxWindowsAdditions-x86 /extract /D=C:\Drivers

   -For the 64-bit drivers:

   • VBoxWindowsAdditions-amd64 /extract /D=C:\Drivers

   

5. Goto device manager

6. add hardware
