linux ubuntu 14.04 with kde and unity installed, nvidia drivers
x86-64 6.2 works normally [as does x86-64 6.5 on a different machine with intel drivers and a much closer to a default install]
both of the x86-64 upstream-binary and the download for ubuntu 14.04 don't show the evaluate in the normal location under the input cell. " Evaluate all" works normally from the menu.
I've tried firefox,chrome browsers under unity.
Any suggestions on conflicts or troubleshooting?
