If you are installing on an x86 system that uses a Keyboard, Video, Mouse (KVM) switch, Solaris might not operate properly if you are using a PS/2 mouse. You might experience the following symptoms:
You only see a black screen while testing the X server configuration in preparation for installation.
The system might hang and will require restarting.
Consequently, you cannot run the Solaris installation program in Graphical User Interface (GUI) mode to install the Solaris OS. You can only proceed by using the command-line interface. After installation, the problem might persist during Solaris runtime.
Workaround: Connect the PS/2 mouse directly to the system. You can use a USB mouse with the switch if the switch supports USB devices.
