我的AVD模拟器不会在Ubuntu上加载

I usually develop my android tests at Windows using the Eclipse IDE. But now that I am needing to do the same at Ubuntu, for some unknown reason the emulator isn't getting loaded, but is getting frozen at the android launching screen. It doesn't show any error message, just get stopped on that screen(I am waiting for more than 2 hours), I don't know why. I am using the Ubuntu 12.04 Precise-Pangolin, and trying to launch the Android 2.2(Froyo) at emulator.I usually develop my android tests at Windows u
