The dash home button brings up a panel that is greyed out, but it is totally empty.

It seems to be the very same issue as this: Dash home button brings up blank window which is unanswered.

I've tried a unity --reset but that doesn't seem to work. Unity seems to reset, but I get the following warning over and over: cs space validation failed unity

What should I do next to try and fix this?

Edit: Attempted fixes: I've refomatted, did not work. I've done apt-get remove unity then apt-get update then apt-get install unity, did not work.

I've switched to Unity 2d and this seems to work. How can I get regualar Unity working or atleast find the error?
