Because the ansible version comes with Ubuntu 17.04 is quite all (1.6.2), it may cause you troubles like missing module directory... After a while, I figured that PIP is the best way to install Ansible on Ubuntu 17.04. 1. Install the needed libs: $ sudo apt install libffi-dev libssl-dev libxml2-dev libxslt1-dev openssl-dev python-dev libffi-dev python-pip 2. Then install Ansible: $ sudo pip install ansible 3. Fix AttributeError : 'module' object has no attribute 'PROTOCOL_SSLv3' error when running Ansible: http://www.dangtrinh.com/2017/06/how-to-fix-attributeerror-module-object.html 4. Enjoy!

In some cases, I have to set my Ubuntu computer to run with a screen resolution that does not show up in the Settings (1366x768 or 16:9, because the monitor does not support it). Here is a pretty neat strick: 1. Check all the support screen sizes and device names: xrandr Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 VGA-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 410mm x 230mm 1024x768 75.03 60.00 800x600 75.00 60.32 640x480 75.00 59.94 720x400 70.08 Remember name of the device which is VGA-1. 2. Run the cvt command to calculate the VESA Coordinated Video Timing modes: cvt 1366 768 # 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz Modeline "1368x768_60.00" 85.25 1368 1440 1576 1784 768 771 781 798 -hsync +vsync Remember the modeline which is in bold. 3. Create a new mode with the xrandr: sudo xrandr --nemode "1368x768_60.00"
