X Server extensions
Besides some standard X server extensions A
RGUS
offers a set of additional specialized X server extensions. These
extensions are mentioned here briefly. Full documents for software development are available on request.
X MultiCursor (XMC)
The X MultiCursor extension allows the simultaneous use of several mouse pointers, which can be moved inde-
pendently from each other over the root window. The XMC extension behaves like the standard X.11 input ex-
tension of the X Consortiums and can be handled exactly the same way.
Note that the X MultiCursor can not be used simultaneously together with multiple logical
screens, see section
X Blink
With the X Blink extension, a blinking property can be put on shared color cells. A blinking color has two color
information. These two colors are changed with an optional frequency. DIN blinking frequencies are provided.
