Registry key Description
root/ConnectionType/xen/general/
twRedundantImageItems
Controls the number of screen areas that will be tracked in
ThinWire to prevent redundant drawing of bitmap images. An
adequate value for 1024x768 sessions is 300.
root/ConnectionType/xen/general/
useAlternateAddress
If set to 1, an alternate address is used for rewall connections.
This setting directly maps to the Citrix .ini le setting
UseAlternateAddress.
root/ConnectionType/xen/general/
useBitmapCache
If set to 1, the persistent disk cache is enabled. The persistent
disk cache stores commonly-used graphical objects such as
bitmaps on the hard disk of the thin client. Using the persistent
disk cache increases performance across low-bandwidth
connections but reduces the amount of available disk space on
the thin client. For thin clients on high-speed LANs, usage of the
persistent disk cache is not necessary. This setting directly maps
to the Citrix .ini le setting PersistentCacheEnabled.
root/ConnectionType/xen/general/useEUKS
Controls the use of Extended Unicode Keyboard Support (EUKS)
on Windows servers. If set to 0, EUKS is not used. If set to 1, EUKS
is used as a fallback. If set to 2, EUKS is used whenever possible.
root/ConnectionType/xen/general/useLocalIM
If this setting is enabled, the local X input method is used to
interpret keyboard input. This is supported for European
languages only. This setting directly maps to the Citrix .ini le
setting useLocalIME.
root/ConnectionType/xen/general/userAgent
The string from this key will be presented by the Citrix client and
will be helpful for administrators to know where the connection
request is from.
root/ConnectionType/xen/general/
waitForNetwork
If set to 1, the connection will not be launched until networking is
available. This ensures that, on a slow network, the connection
does not launch before networking is available, which could cause
a failure.
root/ConnectionType/xen/general/
webcamFramesPerSec
Controls the HDXWebCamFramesPerSec variable in the
All_Regions.ini le.
root/ConnectionType/xen/general/webcamSupport
If set to 0, the webcam and webcam audio are disabled. If set to 1,
the webcam and webcam audio are enabled, with compression. If
set to 2, USB redirection of the webcam and webcam audio is
enabled.
root/ConnectionType/xen/general/windowHeight
Sets the height of the window in pixels if windowSize is set to
Fixed Size.
root/ConnectionType/xen/general/windowPercent
Sets the size of the window as a percentage if windowSize is
set to Percentage of Screen Size.
root/ConnectionType/xen/general/windowSize
If set to Default, the server-side settings are used. If set to
Full Screen, the window is maximized without borders on all
available screens. If set to
Fixed Size, the windowWidth
and windowHeight registry keys can be used to specify the size
of the window in pixels. If set to Percentage of Screen
Size
, the windowPercent key can be used to specify the size
of the window as a percentage. For Percentage of Screen
Size to take eect, enableForceDirectConnect must be
set to 1 and TWIMode must be set to 0. This setting only works
with XenApp and only if the server allows direct connections. This
setting does not work with XenDesktop.
