Jupyter was deployed on one LXD container and Apache was deployed on another. At first Jupyter kept complaining “Connecting to kernel… Failed.”

Ubuntu: 16.04LTS

Apache: Server version: Apache/2.4.18 (Ubuntu)

Solution:

Add those two lines BEFORE “/” one:

ProxyPass /api/kernels/ ws://xxx.lxd:8888/api/kernels/
ProxyPassReverse /api/kernels/ http://xxx.lxd:8888/api/kernels/

AND: make sure proxy_wstunnel is enabled for Apache:

a2enmod proxy proxy_wstunnel

Re: Left handed mouse pointerin response to sipilevi

You can use the following app called Mousecape:

https://github.com/alexzielenski/Mousecape/releases/tag/0.0.5

After downloading, installing both the app and the helper app, do the following:

1. Go to the Mousecape preferences and choose “I am left handed”.
2. Dump the system cursors into a cape from the menu: “Capes” → “Dump Cursors”
3. Apply the Cursor Dump cape (right click → apply)
4. Done!
