6.4.5 CDE’s Static Dependency on the Network
CDE has a static dependency on the state of the network configuration. For
more information, see Section 4.4.4.
6.4.6 The xnlLanguage Resource Settings May Cause Problems
with CDE
CDE users should remove any xnlLanguage resource settings from their
.Xdefaults files. Those settings are typically left over from one of the
user’s earlier DECwindows sessions, where the user selected a language from
the session manager’s language menu and then saved that setting.
The xnlLanguage settings should be removed because they override
whatever language you select from the language menu in the CDE login
window.
6.4.7 Possible Failure in the XOpenDisplay Call
When logging in to the CDE desktop, some applications may not restart.
The X server process may not be able to handle all of the requests for new
open connections, causing some to fail in the XOpenDisplay call. Some
applications, like xterm, log startup errors in the dxconsole window,
such as the following error:
xterm error: can’t open display :0
To avoid this problem, add the following resource to your
$HOME/.Xdefaults file:
Dtsession*contManagement: 2
This resource enables a handshake protocol between the CDE session
manager and window manager during the login phase to control the
appearance of new windows. While it may marginally increase the time
before the login completes, it better assures that all applications will be
restarted.
This can be added to the /usr/dt/app-defaults/C/Dtsession file
to make the change for all users automatically.
