I'm developing a kiosk like PC so it doesn't need most of the services.QuestionsWhy can't we disable some services showed in system-config-service?Is there any way to disable all (or at least most) of the services that show up in system-config-services?
Why can't I disable some of the services in system-config-services?
fedora;xfce;services
You don't say which services, which is really what's critical to this entire conversation. But I can say this. Not all services can just be disabled. Some services are required by other services, and so you cannot just shut them off without at least turning off the other services that are using them.          There is not simple way that I've ever seen where you can just disable a group of services without going through and identifying first what they are and second whether they're required by your system or not.Finding out what each service is, just requires you to go through each one in the service name pane (left) and reading the description in the (right) pane. You can also get a list of what services are running along with their state from the command line:$ systemctl list-units -t service --all UNIT                                                           LOAD   ACTIVE   SUB     DESCRIPTIONabrt-ccpp.service                                              loaded active   exited  Install ABRT coredump hookabrt-oops.service                                              loaded active   running ABRT kernel log watcherabrt-vmcore.service                                            loaded inactive dead    Harvest vmcores for ABRTabrt-xorg.service                                              loaded active   running ABRT Xorg log watcherabrtd.service                                                  loaded active   running ABRT Automated Bug Reporting Toolaccounts-daemon.service                                        loaded active   running Accounts Servicealsa-restore.service                                           loaded inactive dead    Restore Sound Card Statealsa-state.service                                             loaded active   running Manage Sound Card State (restore and store)alsa-store.service                                             loaded inactive dead    Store Sound Card Stateatd.service                                                    loaded active   running Job spooling toolsauditd.service                                                 loaded active   running Security Auditing Serviceavahi-daemon.service                                           loaded active   running Avahi mDNS/DNS-SD Stackbluetooth.service                                              loaded active   running Bluetooth servicecolord.service                                                 loaded active   running Manage, Install and Generate Color Profilescrond.service                                                  loaded active   running Command Scheduler...You can read more about the command line by taking a look at this Fedora document titled: F.9.5.
