Chapter 2: Troubleshooting
Icons at the Edges of the Screen Not Visible
When you switch from a high resolution (1280 x 1024 pixels) CRT monitor to
the Presenter, icons that were on the upper and right edges of the screen may
disappear. This is because the CRT monitor changes to 1024 x 768 pixels.
There are two ways to fix this:
1. Move the icons away from the edges of the screen on your CRT monitor
before connecting the Presenter.
2. Or unplug the Presenter power cable, and from a shell window on your
CRT monitor, type the following:
su
/etc/killall Xsgi
This returns the CRT monitor to 1280 x 1024 pixels. Then move the
icons away from the edges of the screen. Reconnect the Presenter’s
power cable, and restart the Presenter from the Monitor Control Panel.
(See “Restarting the Presenter Monitor” on page 7.)
No Sound From the Stereo Speakers
1. If the Presenter board kit for your workstation included a short, black,
audio cable, check that the small, black audio cable is installed correctly.
If necessary, see the manual that comes with the Presenter board for
your workstation.
2. The stereo speakers may have been muted in order to use headphones.
To turn on the speakers, choose “Control Panels” from the Find menu
in the Toolchest and double-click the apanel icon. Select “Presenter
Audio” from the Options menu. If the
Mute button on the Presenter
Audio panel is activated, click on it to turn on the speakers.
