If you are using a non-English language keyboard, the screen display may not match the keyboard input. In this case, you should specify the keyboard type and layout that you are using. For more information about specifying keyboards, see Control keyboard behavior.
Some window managers continuously report the new window position when moving a window, which can result in excessive redrawing. To fix this problem, switch the window manager to a mode that draws window outlines only when moving a window.
Seamless mode removes local window manager decorations such as the title bar and borders, and instead uses decorations sent from the server. Different window managers use different ways of removing window decorations.
Receiver sets the _MOTIF_DECORATIONS hint to remove the decorations. It also sets the class of all seamless windows to “Wfica_Seamless”, so that a window manager that does not recognize the Motif hint can be told to remove the decorations through resource file entries.
Receiver creates window icons that work with most window managers, but are not fully compatible with the X Inter-Client Communication Convention.
To provide full icon compatibility
The cursor can be difficult to see if it is the same or similar in color to the background. You can fix this by forcing areas of the cursor to be black or white.
To change the color of the cursor
CursorStipple=ffff,ffff (to make the cursor black)
CursorStipple=0,0 (to make the cursor white)
When you move the mouse into or out of a connection window, the colors in the non-focused window may start to flash. This is a known limitation when using the X Windows System with PseudoColor displays. If possible, use a higher color depth for the affected connection.
Users have the option of using 256 colors when connecting to a server. This option assumes that the video hardware has palette support to enable applications to rapidly change the palate colors to produce animated displays.
TrueColor displays have no facility to emulate the ability to produce animations by rapidly changing the palette. Software emulation of this facility is expensive both in terms of time and network traffic. To reduce this cost, Receiver buffers rapid palette changes, and updates the real palette only every few seconds.
Receiver uses EUC-JP or UTF-8 character encoding for Japanese characters, while the server uses SJIS character encoding. Receiver does not translate between these character sets. This can cause problems displaying files that are saved on the server and viewed locally, or saved locally and viewed on the server. This issue also affects Japanese characters in parameters used in extended parameter passing.
Full-screen sessions span all monitors by default, but a command-line multi-monitor display control option, -span, is also available. It allows full-screen sessions to span multiple monitors.
The - span option has the following format:
If h is specified, a list of monitors is printed on stdout. And if that is the whole option value, wfica then exits.
If o is specified, the session window will have the override-redirect redirect attribute.
If a is specified, Receiver tries to create a session that covers all monitors.
Receiver assumes that the rest of the -span option value is a list of monitor numbers. A single value selects a specific monitor, two values select monitors at the top-left and bottom-right corners of the required area, four specify monitors at the top, bottom, left and right edges of the area.
Assuming o was not specified, wfica will use the _NET_WM_FULLSCREEN_MONITORS message to request an appropriate window layout from the window manager, if it is supported. Otherwise it will use size and position hints to request the desired layout.
The following command can be used to test for window manager support:
xprop -root | grep _NET_WM_FULLSCREEN_MONITORS
If there is no output, there is no support. If there is no support, you may need an override-redirect window. You can set up an override-redirect window using -span o.
To make a session the spans multiple monitors from the command line
export WFICA_OPTS="-span a"Note that this change affects both XenApp and XenDesktop sessions.
