After installation and configuration of a SUSE Linux Enterprise based product the system is being attachted to a keyboard / mouse switch. When systems starts up and the login manager loads the mouse does not work anymore.


Passing psmouse.proto=protocol_name as option to the kernel at boot time might help to solve the issue. This option supports the following protocols:
  • bare
  • imps
  • exps
  • lifebook
  • any
Please start by trying psmouse.proto=bare. If this does not help, try any other option from the list above.

Additional Information

Please check /usr/src/linux/Documentation/kernel-parameters.txt for updates or changes to the supported protocols. The file is part of the kernel-source.rpm.
To pass the options to the kernel each time the system start, changes to either /boot/grub/menu.lst or/etc/lilo.confare necessary. Please see SDB - Inserting_Boot_Options_Permanently for more information.
