Srinidhi, Drivers are just supposed to drive hardware and make it available to user-space. They are not supposed to generate UI, and so there are no mechanisms available for doing these things from within the kernel. Instead you should create a user-space daemon that drives all these types of interactions.

I am working on a kernel driver, when I need to play a system beep based on some event. But, so far I am unable to find any method of doing so. Can any one provide some pointers for this? Also, is there is any way of changing cursor (mouse) from the kernel driver? Thanks for any help....
