+# Troubleshooting
+## My GLFW window is blank:
+If you have more than one GPU, for windowed (no browser) demos you must specify a display GPU by setting: `NVIDIA_VISIBLE_DEVICES=1` in the `.env` file, or docker command. Sometimes it takes a few seconds for things to load too.
 
-## Start
-Most demos can be started anywhere with: `yarn demo`, then selected from a list.
-Or started directly with a directory, such as: `yarn demo modules/demo/graph`
-Or with `yarn start` in the demo's own directory. 
+## Starting the demo produced an error:
+Make sure you have downloaded the required datasets, the data is not malformed, and it is in the correct location -usually `/data`.
+If that does not work and if you are running a locally built environment, try rebuilding the module.
+Some demo's may have stopped working - check our **[Issues](https://github.com/rapidsai/node/issues)** for details.
