USB mouse problem on IBM T20?

HowJ · 10-13-2004, 12:49 AM

I've just installed Slackware10 on my T20, everything seems OK but the usb mouse.

My usb mouse is MS WheelMouseOptical, it can work if it's pluged to PS/2 port but to USB port it doesn't work.

The TrackPoint works well.

I tried to use 'mouseconfig' to change the port to USB but it failed when system boot.

How can I make the usb mouse work? Should I modify the protocol in /etc/X11/xorg.conf to "USB"?(now is "IMPS/2"or"PS/2")

I had the same problem on a T21, running SL10.

You may first want to try the various suggestions for tinkering with your xorg.conf. There are a number of sample XF86Configs floating around the Net that are made especially for T2x Thinkpads. I've put the pertinent section form mine below.

BTW, I've now got my USB cordless optical mouse working at the same time as the track point.

Code:

Section "ServerLayout"
  Identifier "XFree86 Configured"
  Screen 0 "Screen0" 0 0
  InputDevice "Keyboard0" "CoreKeyboard"
  InputDevice "PS/2 Mouse" "CorePointer"
  InputDevice "USB Mouse" "SendCoreEvents"
EndSection

Section "ServerFlags"
  Option "AllowMouseOpenFail" "true"
EndSection

##[[ I'm omitting all the keyboard and monitor stuff for this forum post ]]

 Section "InputDevice"
  Identifier "PS/2 Mouse"
  Driver "mouse"
  Option "Protocol" "auto"
  Option "Device" "/dev/mouse"
  Option "Emulate3Buttons" "false"
  Option "Emulate3Timeout" "70"
  Option "ZAxisMapping" "4 5"
  Option "Buttons" "5"
 EndSection

 Section "InputDevice"
  Identifier "USB Mouse"
  Driver "mouse"
  Option "Device" "/dev/input/mice"
  Option "Protocol" "IMPS/2"
  Option "Buttons" "5"
  Option "ZAxisMapping" "4 5"
 EndSection

In my case, changing xorg.conf wasn't enough to get both my TrackPoint and my USB optical mouse working. I finally had the follow the steps on this page, which include a kernel recompile to insure full USB support:

Note that I had already tried the older 2.4.x kernel, then upgraded it to 2.6.7. Neither supported my twin-mouse setup without tweaking.

Thanks for your reply.

I think it's the T20's problem because I configured the same mouse and touchpad on a SAMSUNG Q10 before.

I will try as you suggested.

See my edited reply above. I put in the pertinent parts of my xorg.conf and included a link to a page that got me where I needed to be.

Is this your current configuration?

Does the trackpoint on T21 have 5 buttons? There are only 3 buttons on T20.

I know the meaning of the configuration so I will try to modify it soon.

Wish it will be ok

One question more: which protocol you choose while gpm load? I mean in the command "mouseconfig", choose which is correct? THX

Yes, it is.

No, my trackpoint has just 3 buttons, but I lifted this section from several other people's configs. Since it didn't cause any problems, I left it alone. The "5 button" stuff under the trackpoint ("PS/2 Mouse") section is probably unnecessary.

When I installed Slack 2.4.x the second time, I didn't choose the gpm option, since I was worried that it might have been causing a problem. So I can't answer this question, I'm afraid. However, I suspect gpm is turned back on in my upgraded kernel, because I seem to have full mouse action in console windows.

Thanks very much!

I've solved the problem without recompiling

, just modify the xorg.conf and with gpm I chose IMPS/2.

Thanks for your help again!
