Windows sessions through the Windows connector ignore multi-monitor layout or resolution changes that happen automatically or are triggered by the user (for example, the xrandr command).

Workaround: For a Windows session to use new multi-monitor layout or resolution information on the client, you must restart the Windows connector (run the uttsc command again).

Reference: CR 13086346

The -X xrandr option with uttsc command is not supported when using the Windows connector on Linux. This means that with multiple monitors, the Windows session cannot determine the layout and size of the monitors if this option is used.

Workaround: Do not specify the -X option. By default, the -X xinerama option will be used to enumerate monitor information.

The Windows login chime is distorted when using the uttsc command to log in to a Windows server running Windows 2003 R2 and Windows XP. This happens on Sun Ray servers running Oracle enterprise Linux 5.5.

Reference: CR 12305002

This hang is due to the multi-monitor enumeration process that occurs between the server and the Windows connector, and it is caused by the Windows server not sending monitor layout data to the Windows connector.

Workaround: Disable the multi-monitor enumeration process using the uttsc -X off command.

Fixed in Sun Ray Software 5.2.6 release.

Rapid scrolling, by using the scroll bar or arrow keys, over a large amount of pages may corrupt the content being scrolled. This issue can happen with applications like browsers, PDF viewers, and word processors.

Workaround: Minimizing and maximizing the application restores the corrupted areas. Slower scrolling will also prevent this from happening.

If Xrender extension is disabled on a client, a black mouse cursor is displayed instead of a white mouse cursor in a Windows 2008 R2 session.

Workaround: See How to Enable or Disable Xrender section in the Sun Ray Software 5.2 Administration Guide.

Problems include audio distortion, video slowing down, or the video hanging. This is due to buffer underruns when transferring the content to the Sun Ray client.

The Windows machine does not have the proper port open for the firewall. The multimedia redirection feature requires that a TCP port between 6000 and 10000 must be open for the firewall.

Workaround: Opening port 6000 should be sufficient unless some other service is using it.

With some scanners, scanning does not work when initiated by the button on the scanner. You can still scan documents by initiating the scan from the software.

The Explore Window (disk contents) is not launched automatically after inserting a flash disk. The program must be manually launched. This is a different behavior than the Windows behavior on a console session.

To use smart cards to authenticate users to the Windows Terminal Server, install the Base Smart Card Cryptographic Service Provider Package update from http://support.microsoft.com/kb/909520/en-us.

This update improves screen unlocking behavior in the Sun Ray environment.

Workaround: Use other file systems than PCFS, such as UFS, ext3, or etc.

The Adobe Flash Acceleration and Sun Ray Audio Driver components require hardware that supports the Windows Performance Counter API. If the Windows Performance Counter API is not working properly, the components might fail to load or behave unexpectedly. In one known example, this problem occurs when a computer has the AMD Cool'n'Quiet technology enabled in the BIOS, which is documented in http://support.microsoft.com/kb/895980.
