6937146 – Audio Unavailable for X Applications Hosted on 64-Bit Linux Application Servers

3.1.5. 6937146 – Audio Unavailable for X Applications Hosted on 64-Bit Linux

Application Servers

Problem: Audio might not play in X applications that are hosted on 64-bit Linux application servers. The

issue is seen for X applications that are hard-coded to use the /dev/dsp or /dev/audio device, and the

Audio Redirection Library (--unixaudiopreload) attribute is enabled.

Cause: A known issue. A 64-bit SGD Audio Redirection Library is not included in the SGD Enhancement

Module.

Solution: No known solution at present.

3.1.6. 6942981 – Application Startup is Slow on Solaris Trusted Extensions

Problem: On Oracle Solaris Trusted Extensions platforms, startup times for Windows applications and X

applications might be longer than expected.

Cause: By default, the X Protocol Engine attempts to connect to X display port 10. This port is unavailable

when using Solaris Trusted Extensions. After a period of time, the X Protocol Engine connects on another

X display port and the application starts successfully.

Solution: Do either of the following:

• Change the default minimum display port used by the SGD server.

Configure the following setting in the xpe.properties file in the /opt/tarantella/var/

serverconfig/local directory on the SGD server:

tarantella.config.xpeconfig.defaultmindisplay=11

Restart the SGD server after making this change.

• Exclude the unavailable port from use by the X Protocol Engine.

In the Administration Console, go to the Protocol Engines, X tab for each SGD server in the array and

type -xport portnum in the Command-Line Arguments field, where portnum is the TCP port number

to exclude.

Alternatively, use the following command:

$ tarantella config edit --xpe-args "-xport portnum"

For example, to exclude X display port 10 from use by the X Protocol Engine:

$ tarantella config edit --xpe-args "-xport 6010"

The changes made take effect for new X Protocol Engines only. Existing X Protocol Engines are not

affected.

3.1.7. 6957820 – SGD Client Hangs When Using Smart Card Authentication for

Windows Applications

Problem: When using a smart card to log in to a Windows application session from a Ubuntu Linux 10.04

client device, the SGD Client hangs after the user exits the authenticated application session. The user

might not be able to start any further applications or log out from SGD.

Cause: A known issue with version 1.5.3 of PCSC-Lite on Ubuntu client platforms.
