The following policies can be configured in Citrix Studio Version 7.12 and later.

  • MaxSpeexQuality

    Value (integer): [0 - 10]

    Default value: 5

    Details:

    Audio redirection encodes audio data with the Speex codec when audio quality is medium or low (see the policy Audio quality). Speex is a lossy codec, which means that it achieves compression at the expense of fidelity of the input speech signal. Unlike some other speech codecs, it is possible to control the tradeoff made between quality and bit rate. The Speex encoding process is controlled most of the time by a quality parameter that ranges from 0 to 10. The higher the quality is, the higher the bit rate.

    The max Speex quality chooses the best Speex quality to encode audio data according to audio quality and bandwidth limit (see the policy Audio redirection bandwidth limit). If the audio quality is medium, the encoder is in wide band mode, which means a higher sampling rate. If the audio quality is low, the encoder is in narrow band mode, which means a lower sampling rate. The same Speex quality has different bit rates in different modes. The best Speex quality is when the largest value meets the following conditions:

    • It is equal to or less than the max Speex quality.
    • Its bit rate is equal to or less than the bandwidth limit.

  • PrimarySelectionUpdateMode

    Value (enum): [0, 1, 2, 3]

    Default value: 3

    Details:

    Primary selection is used when you select data and paste it by pressing the middle mouse button.

    This policy controls whether primary selection changes on the Linux VDA and client can update the clipboard on each other. There are four value options:

    image of primary selection update mode

    • Selection changes are not updated on neither client nor host
      Primary selection changes on the Linux VDA do not update the clipboard on the client. Primary selection changes on the client do not update the clipboard on the Linux VDA.

    • Host selection changes are not updated to client
      Primary selection changes on the Linux VDA do not update the clipboard on the client. Primary selection changes on the client update the clipboard on the Linux VDA.

    • Client selection changes are not updated to host
      Primary selection changes on the Linux VDA update the clipboard on the client. Primary selection changes on the client do not update the clipboard on the Linux VDA.

    • Selection changes are updated on both client and host
      Primary selection changes on the Linux VDA update the clipboard on the client. Primary selection changes on the client update the clipboard on the Linux VDA. This option is the default value.

    Related Setting: Clipboard selection update mode

  • ClipboardSelectionUpdateMode

    Value (enum): [0, 1, 2, 3]

    Default value: 3

    Details:

    Clipboard selection is used when you select some data and explicitly request it to be “copied” to the clipboard, such as by selecting “Copy” from the shortcut menu. Clipboard selection is primarily used in connection with Microsoft Windows clipboard operations while primary selection is unique to Linux.

    This policy controls whether clipboard selection changes on the Linux VDA and client can update the clipboard on each other. There are four value options:

    image of clipboard selection update mode

    • Selection changes are not updated on neither client nor host
      Clipboard selection changes on the Linux VDA do not update the clipboard on the client. Clipboard selection changes on the client do not update the clipboard on the Linux VDA.

    • Host selection changes are not updated to client
      Clipboard selection changes on the Linux VDA do not update the clipboard on the client. Clipboard selection changes on the client update the clipboard on the Linux VDA.

    • Client selection changes are not updated to host
      Clipboard selection changes on the Linux VDA update the clipboard on the client. Clipboard selection changes on the client do not update the clipboard on the Linux VDA.

    • Selection changes are updated on both client and host
      Clipboard selection changes on the Linux VDA update the clipboard on the client. Clipboard selection changes on the client update the clipboard on the Linux VDA. This option is the default value.

    Related Setting: Primary selection update mode

Note:

The Linux VDA supports both clipboard selection and primary selection. To control the copy and paste behaviors between the Linux VDA and the client, Citrix recommends that you set both clipboard selection update mode and primary selection update mode to the same value.
