Expanded tablet mode in Windows 10 using Windows Continuum

Windows Continuum is a Windows 10 feature that adapts to the way the client device is used. Citrix Workspace app for Windows Version 4.10 and later supports Windows Continuum, including dynamic change of modes.

For touch-enabled devices, the Windows 10 VDA starts in tablet mode when there is no keyboard or mouse attached. It starts in desktop mode when either a keyboard or a mouse or both are attached. Detaching or attaching the keyboard on any client device or the screen on a 2-in-1 device like a Surface Pro toggles between tablet and desktop modes. For more information, see Tablet mode for touchscreen devices in Citrix Virtual Apps and Desktops documentation.

The Windows 10 VDA detects the presence of a keyboard or a mouse on a touch-enabled client device when you connect or reconnect to a session. It also detects when you attach or detach a keyboard or mouse during the session. This feature is enabled by default on the VDA. To disable the feature, modify the Tablet mode toggle policy using Citrix Studio.

Tablet mode offers a user interface that is better suited to touchscreens:

  • Slightly larger buttons.
  • The Start screen and all apps you start open in a full screen.
  • The taskbar contains a Back button.
  • Icons are removed from the taskbar.

Desktop mode offers the traditional user interface where you interact in the same manner as using a PC with a keyboard and mouse.

Note

Workspace for Web does not support Windows Continuum feature.

For more information, see XenServer 7.2 Release Notes

Relative Mouse

Relative Mouse support provides an option to interpret the mouse position in a relative rather than an absolute manner. This capability is required for applications that demand relative mouse input rather than absolute.

Note

This feature can be applied in a published desktop session only.

To enable Relative Mouse support

  1. Log on to Citrix Workspace app.
  2. Launch a published desktop session.
  3. From the desktop viewer toolbar, select Preferences.

    The Citrix Workspace - Preferences window appears.

  4. Select Connections.
  5. Under Relative Mouse settings, enable Use relative mouse.
  6. Click Apply and OK.

NOTE

This is a per-session feature. It does not persist after reconnecting to a disconnected session. Users must re-enable the feature every time they connect or reconnect to the published desktop.

Hardware decoding

When using Citrix Workspace app (with HDX engine 14.4), the GPU can be used for H.264 decoding wherever it is available at the client. The API layer used for GPU decoding is DirectX Video Acceleration.

To enable hardware decoding using Citrix Workspace app Group Policy Object administrative template:

  1. Open the Citrix Workspace app Group Policy Object administrative template by running gpedit.msc.
  2. Under the Computer Configuration node, go to Administrative Templates > Citrix Workspace >User Experience.
  3. Select Hardware Acceleration for graphics.
  4. Select Enabled and click Apply and OK.

localized image

To validate if the policy was applied and hardware acceleration is being used for an active ICA session, look for the following registry entries:

Registry Path: HKEY_CURRENT_USER\SOFTWARE\Citrix\ICA Client\CEIP\Data\GfxRender

Tip

The value for Graphics_GfxRender_Decoder and Graphics_GfxRender_Renderer should be 2. If the value is 1, that means CPU based decoding is being used.

When using the hardware decoding feature, consider the following limitations:

  • If the client has two GPU’s and if one of the monitors is active on the 2nd GPU, CPU decoding will be used.
  • When connecting to a Citrix Virtual Apps server running on Windows Server 2008 R2, Citrix recommends that you do not to use hardware decoding on the user’s Windows device. If enabled, issues like slow performance while highlighting text and flickering issues will be seen.

Client-side microphone input

Citrix Workspace app supports multiple client-side microphone input. Locally installed microphones can be used for:

  • Real-time activities, such as softphone calls and Web conferences.
  • Hosted recording applications, such as dictation programs.
  • Video and audio recordings.

Citrix Workspace app users can select whether to use microphones attached to their device using Connection Center. Citrix Virtual Apps and Desktops users can also use the Citrix Virtual Apps and Desktops viewer Preferences to disable their microphones and webcams.

Multi-monitor support

You can use up to eight monitors with Citrix Workspace app for Windows.

Each monitor in a multiple monitor configuration has its own resolution designed by its manufacturer. Monitors can have different resolutions and orientations during sessions.

Sessions can span multiple monitors in two ways:

  • Full screen mode, with multiple monitors shown inside the session; applications snap to monitors as they would locally.

    Citrix Virtual Apps and Desktops: To display the desktop viewer window across any rectangular subset of monitors, resize the window across any part of those monitors and click Maximize.

  • Windowed mode, with one single monitor image for the session; applications do not snap to individual monitors.

Citrix Virtual Apps and Desktops: When any desktop in the same assignment (formerly “desktop group”) is launched subsequently, the window setting is preserved and the desktop is displayed across the same monitors. Multiple virtual desktops can be displayed on one device provided the monitor arrangement is rectangular. If the primary monitor on the device is used by the Citrix Virtual Apps and Desktops session, it becomes the primary monitor in the session. Otherwise, the numerically lowest monitor in the session becomes the primary monitor.

To enable multi-monitor support, ensure the following:

  • The user device is configured to support multiple monitors.
  • The user device operating system must be able to detect each of the monitors. On Windows platforms, to verify that this detection occurs, on the user device, view the Settings tab in the Display Settings dialog box and confirm that each monitor appears separately.
  • After your monitors are detected:
    • Citrix Virtual Desktops: Configure the graphics memory limit using the Citrix Machine Policy setting Display memory limit.
    • Citrix Virtual Apps: Depending on the version of the Citrix Virtual Apps server you have installed:
      • Configure the graphics memory limit using the Citrix Computer Policy setting Display memory limit.
      • From the Citrix management console for the Citrix Virtual Apps server, select the farm and in the task pane, select Modify Server Properties > Modify all properties > Server Default > HDX Broadcast > Display (or Modify Server Properties > Modify all properties > Server Default > ICA > Display) and set the Maximum memory to use for each session’s graphics.

Ensure the setting is large enough (in kilobytes) to provide sufficient graphic memory. If this setting is not high enough, the published resource is restricted to the subset of the monitors that fits within the size specified.

For information about calculating the session’s graphic memory requirements for Citrix Virtual Apps and Desktops, see Knowledge Center article CTX115637.

Printer setting overrides on devices

To override the printer settings on the user device

  1. From the Print menu available from an application on the user device, choose Properties.
  2. On the Client Settings tab, click Advanced Optimizations and make changes to the Image Compression and Image and Font Caching options.

On-screen keyboard control

To enable touch-enabled access to virtual applications and desktops from Windows tablets, Citrix Workspace app automatically displays the on-screen keyboard when you activate a text entry field, and when the device is in tent or tablet mode.

On some devices and in some circumstances, Citrix Workspace app cannot accurately detect the mode of the device, and the on-screen keyboard may appear when you do not want it to.

To suppress the on-screen keyboard from appearing when using a convertible device ,create a REG_DWORD value DisableKeyboardPopup in HKEY_CURRENT_USER\SOFTWARE\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\MobileReceiver and set the value to 1.

Note:

On a x64 machine, create the value in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Configuration\Advanced\Modules\MobileReceiver.

The keys can be set to 3 different modes as given below:

  • Automatic: AlwaysKeyboardPopup = 0; DisableKeyboardPopup = 0
  • Always popup (on-screen keyboard): AlwaysKeyboardPopup = 1; DisableKeyboardPopup = 0
  • Never popup (on-screen keyboard): AlwaysKeyboardPopup = 0; DisableKeyboardPopup = 1

Keyboard shortcuts

You can configure combinations of keys that Citrix Workspace app interprets as having special functionality. When the keyboard shortcuts policy is enabled, you can specify Citrix Hotkey mappings, behavior of Windows hotkeys, and keyboard layout for sessions.

  1. Open the Citrix Workspace app Group Policy Object administrative template by running gpedit.msc.
  2. Under the Computer Configuration node, go to Administrative Templates> Citrix Components > Citrix Workspace > User Experience.
  3. Select the Keyboard shortcuts policy.

  4. Select Enabled, and the desired options.
  5. Restart the Citrix Workspace app session for the changes to take effect.

Citrix Workspace app support for 32-bit color icons

Citrix Workspace app supports 32-bit high color icons and automatically selects the color depth for applications visible in the Citrix Connection Center dialog, the Start menu, and task bar to provide for seamless applications.

Caution

Editing the registry incorrectly can cause serious problems that may require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

To set a preferred depth, you can add a string registry key named TWIDesiredIconColor to HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Preferences and set it to the desired value. The possible color depths for icons are 4, 8, 16, 24, and 32 bits-per-pixel. The user can select a lower color depth for icons if the network connection is slow.

Enabling desktop viewer

Different enterprises have different corporate needs. Your requirements for the way users access virtual desktops may vary from user to user and may vary as your corporate needs evolve. The user experience of connecting to virtual desktops and the extent of user involvement in configuring the connections depend on how you set up Citrix Workspace app for Windows.

Use the desktop viewer when users need to interact with their virtual desktop. The user’s virtual desktop can be a published virtual desktop, or a shared or dedicated desktop. In this access scenario, the desktop viewer toolbar functionality allows the user to open a virtual desktop in a window and pan and scale that desktop inside their local desktop. Users can set preferences and work with more than one desktop using multiple Citrix Virtual Apps and Desktops connections on the same user device.

Note

Use Citrix Workspace app to change the screen resolution on their virtual desktops. You cannot change Screen Resolution using Windows Control Panel.

Keyboard input in desktop viewer sessions

In desktop viewer sessions, Windows logo key+L is directed to the local computer.

Ctrl+Alt+Delete is directed to the local computer.

Key presses that activate StickyKeys, FilterKeys, and ToggleKeys (Microsoft accessibility features) are normally directed to the local computer.

As an accessibility feature of the desktop viewer, pressing Ctrl+Alt+Break displays the desktop viewer toolbar buttons in a pop-up window.

Ctrl+Esc is sent to the remote, virtual desktop.

Note

By default, if the desktop viewer is maximized, Alt+Tab switches focus between windows inside the session. If the desktop viewer is displayed in a window, Alt+Tab switches focus between windows outside the session.

Hotkey sequences are key combinations designed by Citrix. For example, the Ctrl+F1 sequence reproduces Ctrl+Alt+Delete, and Shift+F2 switches applications between full-screen and windowed mode. You cannot use hotkey sequences with virtual desktops displayed in the desktop viewer (that is, with Citrix Virtual Apps and Desktops sessions), but you can use them with published applications (that is, with Citrix Virtual Apps sessions).

Connect to virtual desktops

From within a desktop session, users cannot connect to the same virtual desktop. Attempting to do so will disconnect the existing desktop session. Therefore, Citrix recommends:

  • Administrators should not configure the clients on a desktop to point to a site that publishes the same desktop
  • Users should not browse to a site that hosts the same desktop if the site is configured to automatically reconnect users to existing sessions
  • Users should not browse to a site that hosts the same desktop and try to launch it

Be aware that a user who logs on locally to a computer that is acting as a virtual desktop blocks connections to that desktop.

If your users connect to virtual applications (published with Citrix Virtual Apps) from within a virtual desktop and your organization has a separate Citrix Virtual Apps administrator, Citrix recommends working with them to define device mapping such that desktop devices are mapped consistently within desktop and application sessions. Because local drives are displayed as network drives in desktop sessions, the Citrix Virtual Apps administrator needs to change the drive mapping policy to include network drives.

Changing the status indicator time-out

You can change the amount of time the status indicator displays when a user is launching a session. To alter the time out period, create a REG_DWORD value SI INACTIVE MS in HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\ICA CLIENT\Engine\. The REG_DWORD value can be set to 4 if you want the status indicator to disappear sooner.
