I launched Eclipse on Ubuntu 12.04 and the Unity Launch and Dash suddenly disappeared. I could mouse over where it had disappeared and I could still interact with the invisible dash and launcher. I don't know why its doing this or how to fix it. Here's my system info:
Memory: 2.7 GB
Processor: AMD Athlon(tm) Processor TF-20
Graphics: VESA: RS780MN
OS Type: 32 bit
