Description Paolo Ciarrocchi 2002-12-08 03:17:17 UTC

Exact Kernel version:2.5.50 (same problem with all the version I tried)
Distribution: Mandrake
Hardware Environment: HP Omnibook 6000
Software Environment:
Problem Description: I can not get my pointer working with all the 2.5.*. As 
far as I know the problem is related to the fact that the two pointer share the 
same aux port.

Steps to reproduce: Just boot ;-)

what is the output of 

grep CONFIG_INPUT_ .config

?

This happens to a bunch of people. I have yet to find out how the two
input devices are connected and what to do to enable (or at least not disable) them.

I have the same problem: With 2.6.0-test3 my touchpad and the little "joystick"
build into my laptop stopped to work. Both do run fine as a PS2-mouse in GPM and
XFree on 2.4.21 and older kernels.

I made sure I have the same config-settings as given belog. I compiled ps mouse
as a module though and whenever I load it a synaptics touchpad is discovered.
There are several tries to reset this device which fail.

I followed several instructions on how to use that synaptics driver in GPM and
XFree and can get neither of them to work.

This definitly is a showstopper for me: I can't really use a 2.6-kernel if that
breaks the mouse!

Feel free to ask for more information or tests.

Comment 6 Vojtech Pavlik 2003-08-21 04:41:06 UTC

For proper support of the touchpoint (the little joysticky wart in the middle
of the keyboard), you either have to disable Synaptics support (use
psmouse_noext on the kernel command line) or have Synaptics pass-through support
enabled, which
I'm going to send to Linus today.

Comment 7 Vojtech Pavlik 2004-01-31 14:43:38 UTC

Pass through support has been in the kernel for a while,
does everything work OK now?

Comment 8 Paolo Ciarrocchi 2004-02-01 05:10:28 UTC

I don't have anymore that machine so I cannot test if it works.
I'm sorry but I cannot help you anymore on this specific topic.

Comment 9 Vojtech Pavlik 2004-02-01 05:46:06 UTC

Ok, I'll close it then, since the fix can't be verified.
