Registry key

Description

root/ConnectionType/freerdp/connections/

<UUID>/redirectPreference

For redirection, the RDP client is given several destination

possibilities. It normally tries them in the following order: FQDN,

Primary IP, IP List, NetBIOS. If FQDN is not desired, one of the

alternatives can be tried

ﬁrst

by setting this registry key. If the

speciﬁed

method does not work, the RDP client falls back to the

original order. A setting of

auto

forces the original order.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/remoteFx

If set to 1, RemoteFX is used if available.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/sendHostname

Sets the thin client hostname that is sent to the remote host. If

left blank, the system hostname is sent. The registry key

root/

ConnectionType/view/connections/<UUID>/

xfreerdpOptions/general/sendHostname

must be set

hostname

for this key to be used.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/sound

If set to

Bring to this computer

, sound is redirected from

the remote host to the client using a standard virtual channel. If

set to

Leave at remote computer

, sound is left at the

remote host. This can be useful when using a redirected USB

audio device. If set to any other value, audio is disabled. Generally,

HP recommends setting this value to

Bring to this

computer

and not redirecting USB playback devices to the

remote host. This will improve audio quality and ensure that

client audio redirected via other virtual channels (such as

Multimedia Redirection

) matches local audio settings.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/timeoutError

Sets the number of milliseconds to wait after losing the

connection before giving up on reconnecting with the server. If set

to 0, reconnection is attempted forever.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/timeoutRecovery

Sets the number of milliseconds to wait after losing the

connection for networking to recover without trying a forced

reconnect.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/timeoutWarning

Sets the number of milliseconds to wait after losing the

connection before warning the user that the connection has been

lost.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/timeoutWarningDialog

If set to 1, when an end-to-end connection drop is detected, a

dialog is displayed and the screen will turn grayscale. Otherwise,

messages are written to the connection log and the session

freezes.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/timeoutsEnabled

If set to 1, end-to-end connection health checks are done.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/tlsVersion

Sets the version of Transport Layer Security to be used during the

early stages of negotiation with the RDP server. Either set this to

match the version of TLS used by your RDP server, or try setting it

to auto.

NOTE:

There are some server-side defects in some unpatched

RDP servers that can cause the auto setting to fail, so it is not the

default setting.

root/ConnectionType/view/connections/<UUID>/

xfreerdpOptions/xkbLayoutId

Sets an XKB layout ID for bypassing the system keyboard. To see

the list of available IDs, enter the following command in an X

terminal:

xfreerdp --kbd-list

root/ConnectionType/view/coreSettings/

USBrelevant

Indicates if this connection type is USB-relevant. If it is, it might

have a USB plugin for redirecting USB devices.
