Slicer fails to start on default Ubuntu 20.04 configuration

[lassoan]

Slicer fails to start and displays cryptic message on default Ubuntu 20.04 configuration, due to missing xinerama plugin.

Additional instructions added to installation: https://slicer.readthedocs.io/en/latest/user_guide/getting_started.html#linux to help address this.

Additional options for communicating install instructions:

• Add check to launcher
  • Detect failed start and show message
• Add text / warning to download.slicer.org for linux

After locally editing the html, here is what we could do:

I will add the link to the download site, and then close. Will create a new issue for adding the check to the launcher.

@sjh26 added the link to the download site in Slicer/slicer.org@0cd0fc7.

@sjh26 Based on your previous comment, should this issue be closed and a new issue created for adding the check to the launcher?

Closing. A specific issue discussing approaches for implementing checks has been created.
