Hi,

I am new to linux fb model and had some queries regarding resolution change
mechanisms.

Consider a situation where the frambuffer kernel module (vfb/xenfb etc)
wants to change the resolution.

1. Is there a mechanism to this, considering the applications/windowing
system/console above the framebuffer hasnt initiated the size change?

2. Is there a way to do an upcall into the application/windowing
system/console modules to inform them about the size change asynchronously?

In this particular case ; the display hardware(instead of the user) has
initiated the resolution change.Is it possible in the current fb framework
to support it?

Excuse me for the lack of knowledge in this area.
Any other suggstions/explanations are welcome.

Thanks
jk
