USing x11vnc, the browser does not work when screen is off
 

Using x11vnc works great particularly after viewing

but when the screen is off (does automatically) everything works normally except the browser. It works, but does not open the page even when it is a local html page on the n810.
When I touch the screen (it turns on) the browser works again.
Any idea what this is ?
