●

The HP personal workstations also block input from a directly connected keyboard and mouse when

monitor blanking is occurring. When keyboard or mouse input is received by the remote computer, the

monitor will enter the display powersave mode, and the cursor will be blanked as a result.

●

An exception to input blocking is the Ctrl+Alt+Del key sequence. When this sequence is received by the

remote computer from a directly-connected keyboard, the remote computer desktop will display the

the monitor will exit its powersave mode, and keyboard input will become unblocked until this dialog is

dismissed.

NOTE: Remote computer monitor blanking is not supported if the remote computer is a virtual machine

(e.g., VMware ESX, Citrix Xen, etc).

If monitor blanking is enabled but the remote computer is unable to blank the display (because, for example,

the computer is not one of the supported computers listed previously), a warning dialog is displayed on the

local computer.

NOTE: Linux screen blanking functionality is not supported on dual-monitor systems unless NVIDIA

TwinView is in use.

The remote computer monitor blanking feature can be disabled by setting the following RGS Sender property

to 0 (false).

Rgsender.IsBlankScreenAndBlockInputEnabled

If this property is set to 0, monitor blanking will be disabled, meaning that a monitor connected to the remote

computer will display the user’s desktop session. Furthermore, because monitor blanking is disabled, the

warning dialog will not be displayed. For more details on this property, see

RGS Sender properties

on page 91.

Linux connection considerations

NOTE: The Switch User functionality added to RHEL6 is not supported by RGS.

Full-screen crosshair cursors

Certain applications that use large crosshair cursors (for example, Dassault Systemes ICEM Surf uses a full-

screen crosshair cursor) will not display correctly on the local computer. Full-screen crosshair cursors can be

disabled by typing the following in a terminal window:

X11xprop -root -remove _SGI_CROSSHAIR_CURSOR

This will force the application to use an X cursor, which will display correctly on the local computer.

Gamma correction on the local computer

The color on a 3D application on the remote computer can look incorrect when displayed on a local computer.

This is because the gamma of the local computer monitor may not match the gamma of the remote computer

monitor. To correct this, any tool that will adjust the gamma for a display can be used. Some tools will adjust

the gamma for the entire monitor, while others will adjust the gamma on a per-window basis. Per-window

tools that can be used to adjust only the local computer window will provide the best results.

Black or blank connection session with the RGS Sender on Linux

Connection to an X Server that is configured with less than 24-bit or 32-bit default visuals (depending on the

graphics device) will cause the RGS Sender on Linux to generate a black or blank connection screen. For

example, some default installations may configure a 16-bit visual in /etc/X11/xorg.conf after the
