Try dragging some windows around, scrolling, selecting all the icons on the desktop in a huge selection box etc. Web browsing can still be slow, but much of this is due to the web browser rendering the page. Look for web pages which use static backgrounds that do not scroll (eg Twitter). These pages should refresh much faster now when scrolling the text (but frequently you are still bound by the browser's internal rendering performance).		...and you will then see the default desktop.

If however before calling those scripts you ''export DISPLAY=:0'' then they will use the original X server you created. This is likely the behaviour your want.

 === How to change VPU binary ===
 At the time of writing the VPU instruction cache appears to be sticky. If you have previously run the driver, with VPU offload enabled, in the current session you should reboot if you need to change the VPU binary. For instance, if you are sent an updated version of the VPU binary, copy it into the correct place (or change your VpuElf option), ''reboot'' and then run X. If you do not reboot there is a strong change that the driver will hang.
