Description Ivan Baidakou 2010-08-21 07:27:20 UTC

My touchpad is recognized as PS/2 mouse, not as Synaptics device, as it should. 

The same problem is described here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/565543

cat /proc/bus/input/devices 

I: Bus=0011 Vendor=0002 Product=0005 Version=0000
N: Name="ImPS/2 Generic Wheel Mouse"
P: Phys=isa0060/serio1/input0

U: Uniq=
H: Handlers=mouse0 event1 
B: EV=7

B: REL=103


# grep -i synaptics .config
CONFIG_MOUSE_PS2_SYNAPTICS=y
# CONFIG_MOUSE_SYNAPTICS_I2C is not set

Thanks!

Is the touchpad really Synaptics and not ALPS, Elantech, FSP and so forth? What driver does the other OS uses for it? Also, was tere a kernel that detected the touchpad properly or was it always broken?

If I see another tpconfig output I am gonna scream... The utility does not work.

Please boot with "i8042.debug" on the kernel command line and provide full dmesg. Thanks.

dmesg output with i8042.debug option

Comment 7 Dmitry Torokhov 2010-09-22 18:20:23 UTC

_Full_ dmesg, please. I need to see the device initialization phase, not only you working your touchpad/typing. Probably if you boot into text console you will be able to capture more? Also try adding log_buf_len=131072 to the kernel command line.

Thanks.
