About the scheduling of xorg applications

[ZelluX]

Hi, all

I'm not familiar with x window system and trying to know some details about
process scheduling.

Considering such a situation, some applications are running on x window
systems and one of them, for example, a web browser has the focus. If there
comes an interrupt, such as a keyboard interrupt, and now kernel takes over
the control. My question is that what's the running user-mode application
now, is it the web browser, xserver, or any process is possible?

Many thanks for your reply.
