Hello,

i recently got an IBM T41p Thinkpad. I'm using 2.6.1 kernel
and want to enable my UltraNav on the console.

for the mouse i enabled this in my kernel:
Code:

cube linux # grep INPUT .config
CONFIG_INPUT=y
CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_MOUSEDEV_PSAUX=y
CONFIG_INPUT_MOUSEDEV_SCREEN_X=1024
CONFIG_INPUT_MOUSEDEV_SCREEN_Y=768
# CONFIG_INPUT_JOYDEV is not set
# CONFIG_INPUT_TSDEV is not set
CONFIG_INPUT_EVDEV=y
# CONFIG_INPUT_EVBUG is not set
CONFIG_INPUT_KEYBOARD=y
CONFIG_INPUT_MOUSE=y
# CONFIG_INPUT_JOYSTICK is not set
# CONFIG_INPUT_TOUCHSCREEN is not set
# CONFIG_INPUT_MISC is not set
CONFIG_USB_HIDINPUT=y


I executed the following cmd:
gpm -m /dev/psaux -t synps2 -R

and if i play with the stick and/or the touchpad resp. buttons i got the
following output:

Code:

cube root # gpm -m /dev/psaux -t synps2 -R
cube root # *** err [synaptics.c(2850)]: Sending reset command to PS/2 Device

In 2.6 /dev/input/mouse*, /dev/psaux and /dev/input/mice provide userspace with cooked PS/2 protocol. Apllication can either reqiest bare PS/2, ItelliMouse PS/2 or Explorer PS/2 flavor but not synaptics flavor.

To get your touchpad work you need a patched version of GPM and a special XFree driver that make use of kernels "event" devices. See here:
