Bug Description
Binary package hint: unity
On my Asus 1000HE netbook, adding a second monitor using the Monitors panel makes Unity run unusably slowly. I speculate this is because it seems to be running entirely in software.
It works fine if I disable the internal panel and exclusively use the external monitor, but not with both displays active at the same time.

The same problem here. My netbook is an Asus 1001HA.
If I use just one monitor (the netbook's display or another external monitor), everything works perfectly. But if I use *both* netbook's display and an external monitor, the computer turns unusable.
Using System monitor, I've noticed that the compiz process uses about 85% of CPU time when running on multimonitor setup (despite the memory usage is stable).
