1.14 Viewing PDF Files with KPDF
PDF is probably one of more important document formats. KPDF is a KDE program
that can view and print them.
Start KPDF by pressing Alt + F2 and entering
kpdf
. Load a PDF file with File > Open.
KPDF displays it in its main window. On the left side, there is a sidebar with thumbnails
and a contents view. Thumbnails give an overview of the page. The contents view
contains bookmarks to navigate in your document. Sometimes it is empty, meaning
bookmarks are not supported by this PDF.
To view two pages in the main window, select View > Two Pages. The view depends
on what last two options you activate in the View menu.
Another nice option is to select the area in which you are interested with the select tool
from the toolbar. Draw a rectangle and choose from the pop-up menu whether you need
the selected area as text or as a graphic. It is copied to the clipboard. You can even save
the area to a file.
1.15 Controlling Sound with KMix
YaST identifies and configures the sound cards of your computer automatically. Other-
wise, start the YaST Hardware module and configure the sound card manually. When
your sound card has been configured, you can control the volume and balance of the
sound with a mixer.
TIP: Starting the Mixer
If the mixer icon (a loudspeaker symbol) is not visible in the panel of your
desktop, press
Alt + F2 and enter
kmix
or start the mixer from the main menu.
You usually find it under Volume Control.
By default, clicking the KMix icon in the system tray shows the master controller with
which to increase or decrease the overall volume. To switch off the sound, click the
green LED, which darkens when it is muted. Toggle this option by clicking the LED
again. To fine-tune your sound settings for several channels, right-click the KMix icon
and select Show Mixer Window. In the main window, you can configure Output, Input,
and Switches. Each of the devices featured there has its own context menu that is opened
