What Makes a Modern Linux Desktop, and Why Do You Care?

Linux
Location: D136 Level: Intermediate

(2.78, 9 ratings)

Once upon a time, the Linux desktop was easy to explain. An X server sat on top of the kernel, and applications called either the C library or the kernel directly to get things done.

Today, things are rather less simple.

As demands for desktop and hardware integration have grown, the level of complexity involved has increased greatly. From the hardware abstraction of HAL to the information transmission of dbus, from the policy management of udev to the kernel communication channel of netlink, the boundaries of functionality are unclear and users and developers alike may be confused about which layers perform which functions.

This presentation discusses what now lives between the user and their hardware, why it’s necessary, and how things could be so much worse than they are.
