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

a4z · 05-20-2015, 05:44 AM

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
