When going to sleep I sometimes like to leave my computer on playing  ambient music from an internet radio station. It's a really good intro  to the dreams.

However I don't want to have the computer play and be turned on all  the time so I use a simple auto shutdown program to set the amount of  time in which it should shut itself off.

There are two relatively similar and simple programs that do that,  one suitable for KDE and another for GNOME (or Xfce). Both sit in your  tray and count the time.

KShutdown

KShutdown allows you  to set the exact date and time or "time from now" which is what I and  likely you will want. Just set the time in hours or minutes and click  ok. You can also set it to initiate when a certain application you  select closes which may come in handy sometimes as well.

In addition to auto shutdown you can also set it to auto restart,  hybernate, suspend (sleep), lock screen or logout. Even that's not all  though. There's also an "extras" option which allows you to set a  specific command such as stopping a particular program or terminate a  connection. You can add more programs available for auto stopping as  well.

GShutdown

GShutdown  also allows you to set the date and time or time from now that has to  pass for auto shutdown to be initiated and it can initiate auto restart  or logout (end session) as well. It doesn't have the option to sleep or  hybernate however.

In preferences you can select the method of shut down which may  depend on which desktop environment (KDE, GNOME or Xfce) or display  manager (kdm or gdm) are you using. You can also specify the exact  command it should initiate before executing the auto shutdown, restart  or logout.
