Important Process running on Ubuntu

Asked by Kallol Roy

Can some one list me the important processes running on a Ubuntu system? Or point me to a doc which provides me the same information with the commands to troubleshoot if a particular process is not running?
Would be great if some one can point me for Debian too?

The default OS will run the processes needed for Ubuntu to be Ubuntu. Any you add and remove will be as you customise the OS to your needs.

The truly important processes are init (pid 1) which is the 'mother of all processes' and is started at boot. Xorg which gives the thing which the desktop apps run on.

Can you list me some other processes as we know init is the basic one. But apart from that ... like for DHCP, DNS,FAX,SNMP,Internet services,Print etc...

cat /etc/resolv.conf

Xorg
