X Window System map review

[IL Ka]

Hello.

1. Window manager is a separate client. Word processor and Web browser do
not use it directly. They talk to XOrg an XOrg consults Window manager (if
any) asking it to draw window. Technically, you can run client even without
of Window manager.

2. Drivers may be in Kernel or in Xorg itself. With modern installations
you almost always have drivers inside of kernel, but Xorg can work with
kernels that know nothing about your video (except it is VGA
compatibility).

3. There is also session manager (
https://www.x.org/releases/X11R7.7/doc/libSM/xsmp.html), but it is
fully optional

Everything else look correct IMHO..
