I needed to run a windows application using wine on linux on a headless server.
Here is the solution I have found. Running the application with a software named Xvfb. Xvfb is a virtual frame buffer so there is no need to have a screen attached to the server because it is all run virtually in memory.
Since all the action is running in memory, I use image magic to do a “screenshoot” of the virtual framebuffer. I then save the file on the file system where a web server can display it.
install xvfb and imagemagick
1 2 3 | sudo apt-get install xvfb sudo apt-get install imagemagick sudo apt-get install apache2 |
Start xvfb
1 | Xvfb :1 -screen 0 1280x960x24 & |
Start the windows application with wine
1 | DISPLAY=:1 wine terminal.exe & |
Take a screen capture with the import tool of imagemagick
1 | DISPLAY=:1 import -window root -quality 90 /var/www/html/screenshot.jpg |
