Configure your desktop
Configuring your desktop has changed a lot between KDE 3.5 and KDE 4. For those updating, a bit of explanation is needed.
Icons
Challenge: You want to place icons on your desktop (like: "watch TV" or "play pingus")
Solution:
- with KDE 3.5, right-click and choose "Create link to Application"
- with KDE 4 it is much more complicated:
- the "Desktop folder" approach
- start konqueror, choose "about|KDE". Verify you have KDE 4.2 at least.
- right-click onto your desktop, choose "Desktop Settings" -> "Folder View"
- right-click onto your desktop, choose "create new... -> Link to Application"
- the "drag and drop" approach
- Open a file manager and drag the file you would like onto the desktop. It will appear there as icon.
- the "Desktop folder" approach
Example
Let's assume you want an icon on your desktop that starts konqueror:
- find out where the executable is located
- start a konsole by typing ALT_F2 and konsole
- type
which konqueror
let's assume the response is
/usr/local/bin/konqueror
- locate the executable
- start konqueror by typing ALT_F2 and konqueror
- point your konqueror to where you can find your executable, in this case /usr/local/bin
- drag-and-drop konqueror onto your desktop
Now you can start konqueror by clicking onto the "konqueror" icon on your desktop
Plasma
Your desktop is now based on Plasma. This makes it possible to run plasmoids on it, e.g. a clock that docks directly to your desktop and is not surrounded by a border. To add the "clock" plasmoid, right-click onto your desktop and choose "add widget". E.g. choose the Analog Clock Widget there.
Rearrange your Panel
Most of us are creatures of habit, and like our panel to show icons in a familiar order. Plasma appears to drop icons in a random order, but you can re-arrange them as long as you have KDE 4.1 or later. If you have the Panel Controller (which looks like a Cashew in a semi-circle) on the right hand edge of your panel, you can re-order or change the size and justification of the panel. See Can I move the applets on the panel?
Many more such hints are on the Plasma FAQ page.
Access your files on a remote desktop
Under KDE3, if you had an fstab mount to a remote directory you got an icon on your desktop. This doesn't happen in KDE4, but there's an even better way to reach your files.
Create a folderview (right-click on desktop, Add Widgets, Folderview). It will be pointing to your home directory, by default, but click on the spanner on the handle, to get properties, and you can direct it to open in your remote home. If you keep your folder fairly small you'll be able to scroll down to the exact directory you need, and open it in konqueror (which seems to be the default. It may well be that this can be changed, too.)
