Actually tried running these commands on Ubuntu 16.04 in AWS EC2. Doesn’t work there either. This entire tutorial needs to be fixed, https://ubuntu.com/tutorials/ubuntu-desktop-aws#1-overview. This doesn’t work on any version of Ubuntu I’ve tried. The “Activity” bar on the left doesn’t show up at all, and as carlos-bravo indicated, requires different settings for the xstartup file. Please fix the tutorial/documentation. Thanks.
