reload psmouse when compiled into kernel, or how to fix the trackpoint

Hi,

I have a thinkpad and sometimes after booting the trackpoint does not work
if this happens, on Slackware or Debian/Ubuntu based systems I can do

Code:

modprobe -r psmouse; sleep 2; modprobe psmouse

and than the trackpoint works.

but what could I do on o RedHat/centos or openSuse installation
modprobe psmouse tells me that the module is compiled in, so how can I get the trackpoint to work without a restart?

You can't.
You'll need to find the module parameter that fixes it, then pass that to the kernel at boot. Quick search suggests "psmouse.proto=imps" might work.

thanks, I know this, it is a bit old :-)

I would like to understand what makes the tackpoint not working, I mean there must be a reason that 8 from 10 times it works out of the box, and 2 times it doesn't

It might be old, but it works for me on my X200 and T410 (which are rather old themselves :) ).
P.S.
Which Thinkpad are you using?

w500 never happend, but his is not in use anymore, I always had xorg conf on this

x121e -> happes often, never a xorg conf
T410s -> very rarely but had happened , never a xorg conf
T420s -> cant remember , never a xorg conf
T430s -> very rarely but had happened , never a xorg conf

so it to work out of the box (of course Slackware needs some 50-synaptic.conf placed correctly)

can I restart some udev or something instead of reloading the kernel modules?

This is all I've done to get the trackpoint working: created ~./.xsessionrc.

Code:

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation" 1

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Button" 2

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Timeout" 200

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Wheel Emulation Axes" 6 7 4 5

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Emulation" 1

xinput set-prop "TPPS/2 IBM TrackPoint" "Evdev Middle Button Timeout" 50

No udev rule, nothing in /etc/X11/xorg.conf.d.

[CODE]...

thanks, will give it a trial

even if it does not help to explain this behaviour, and it makes me somehow mad when something is happen and I do not know why it is like it is
