Bug#434722: linux-image-2.6.18-4-686: touchpad is not detected correct
Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-12etch2
Severity: normal
After upgrading my notebook from sarge to etch special touchpad
features like scrolling with fingers didn't work any longer. I was
able to track down the problem to the psmouse module, which is not
able to detect my touchpad correct. Instead it detects only a
generic PS/2 mouse:
atpcvc8c:/home/gerald# dmesg | grep input
input: AT Translated Set 2 keyboard as /class/input/input0
input: USB Mouse as /class/input/input1
input: USB HID v1.00 Mouse [USB Mouse] on usb-0000:00:1d.1-2
drivers/usb/input/hid-core.c: v2.6:USB HID core driver
input: PS/2 Generic Mouse as /class/input/input2
input: PC Speaker as /class/input/input3
I tried to load the psmouse module with different parameters like
proto=exps, but nothing helped.
I also tried to set the correct protocol manually, but
the driver seems to think that it is smarter than the user and
ignores my request:
atpcvc8c:/home/gerald# echo -n "SynPS/2" > /sys/devices/platform/i8042/serio3/protocol
atpcvc8c:/home/gerald# dmesg | grep input
input: AT Translated Set 2 keyboard as /class/input/input0
input: USB Mouse as /class/input/input1
input: USB HID v1.00 Mouse [USB Mouse] on usb-0000:00:1d.1-2
drivers/usb/input/hid-core.c: v2.6:USB HID core driver
input: PS/2 Generic Mouse as /class/input/input2
input: PC Speaker as /class/input/input3
input: PS/2 Generic Mouse as /class/input/input4
Only when I touch on my touchpad and then try to set the protocol manually,
it works:
atpcvc8c:/home/gerald# echo -n "SynPS/2" > /sys/devices/platform/i8042/serio3/protocol
atpcvc8c:/home/gerald# dmesg | grep input
atpcvc8c:/home/gerald# dmesg | tail
