Thinkpad X30 middle-click

You can fix this in the registry by editing the key:

HKEY_CURRENT_USERSoftwareSynapticsSynTPEnhUltraNavPS2

Change "TrackPointMode" to Hex value 2214 from the previous value of 1214. You may have to logout and back in for it to take effect.

This makes the middle mouse button of the TrackPoint behave as a normal middle mouse button instead of activating the scroll function. You can still click-and-hold to scroll if you want to.

This works even if the UltraNav settings don't give you the options shown in @WireGuy's answer and has been confirmed to work in Windows 8 and 10.

With this little program called TPMiddle you can use the trackpoint for scrolling AND middle-click at the same time:

• click and hold: scroll
• single click: middle-click

I use it in the Thinkpad W530 and works very well, might work for the Thinkpad X30 as well.

Note: I read the answer by scoop, but then looked at the specs for the x30. It seems to indicate that the x30 uses ultranav. I have a t61p, and the below works with my ultranav. Worth a try:

Go to Control Panel, Mouse, and click on the UltraNav tab (it may be labeled TrackPoint instead).

In the TrackPoint section, click on the Settings button.

This will bring up the TrackPoint Properties screen.

In the "Choose Scrolling or Magnifying Glass Function" section, pick the Neither option.

Neither probably should be labeled "Middle Mouse Click", but it's not.

I personally use the scroll feature, which is the default. It takes a couple days to get used to it, but it provides better control over scrolling than the trackpad. To use it, click and hold it with your thumb (your cursor will change to scroll bars), then use your index finger on the trackpoint to scroll up/down. After a couple days your thumb will naturally find the 'lip' of the middle button.

Before anyone claims this to be a Ultranav touchpad again, I explicitly states that this is a Synaptics OEM touchpad, and should work with a Synaptics touchpad driver. (Which works on my X31 too). If you install enough Linux on Thinkpads, you'll realize most of them uses Synaptics Touchpads.

Okay - go find a Synaptics touchpad driver - maybe refer to this SuperUser.com thread here, install it, and give it a whirl.
