Issue Description
Q:
How to login in the redhat virtual machine with double-mouse via the VNC?
Adapting to all the versions of the cloud computing.

Alarm Information
None
Handling Process
A:
1. Login in the redhat virtual machine via the VNC, the mouse’s location in the GUI is different from the clicking location.
2. After having installed the redhat virtual machine, if there is the condition of double-mouse while we login via the VNC, we can settle the problem by modifying the configuration file “/etc/X11/xorg.conf”, the modification file “xorg.conf” is as the attachment.
3. The detail modification method:
3.1 Login in the redhat virtual machine via the PUTTY.
3.2 Edit the file “/etc/X11/xorg.conf” via the “vi”.
3.2.1 Find the Section “InputDevice”
Modify the whole beginning part Identifier “Mouse0” as to the following:
Section "InputDevice"
     Identifier "Mouse0"
     Driver "evdev"
     Option "Protocol" "IMPS/2"
     Option "Device" "/dev/input/event2"
     Option "DeviceName" "touchscreen"
EndSection

If there aren’t these fields, add the whole segment.
3.2.2 Find the beginning part of Section "ServerLayout", and insert:
InputDevice    "Mouse0" "CorePointer".
As the following:
Section "ServerLayout"
        Identifier     "Default Layout"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "Mouse0" "CorePointer"
EndSection

3.2.3 Notice: the “Mouse0” at the Identifier "Mouse0" and InputDevice  "Mouse0" "CorePointer" must be the same.
4. Having tested, after rebooting the redhat virtual machine, the problem of double-mouse has been settled.
