The following are some issues that you might encounter when using Linux and GNOME with Maya.
Mouse pointer appears as a black “X”
Sometimes when you right-click and the mouse pointer becomes a black “X” it remains so for the Maya session and even after restarting Maya.
Set the environment variable MAYA_MMSET_DEFAULT_XCURSOR; the value does not matter. If this variable is set, Maya will set the cursor to the left pointing arrow Cursor on exiting the Marking Menu/Hotbox.
When exiting the hotbox with the workaround already in place, the cursor may remain as the right-pointing red arrow. To remedy this, right-click the scene after exiting the hotbox. The cursor becomes the default left-pointing black arrow. However, the red arrow won’t show up again when you enter the hotbox until you log out and log in again.
