Re: Vertical scrolling got reset everytime I use Ultra Nav to scroll vertically

2013-04-18, 2:55 AM

I have just bought a brand new X230 with all the latest drivers and this issue of the mouse wheel scrolling parameter being reset is still happening.  It is ABSOLUTELY unacceptable that Lenovo has not appropriately address this bug. Come on - eight pages of entries on this thread.  It is obviously an issue that Lenovo should be focused on!

I'm experiencing it too with the 16.1.1.0 driver. What the what, Lenovo? Get it together. Is anyone still watching this thread?

This problem is very much still alive on the T450s with all drivers updated and running Windows 8.1. How many years does it take to fix a bug like this and ensure that it doesnt return in the next patch :)

Re: Vertical scrolling got reset everytime I use Ultra Nav to scroll vertically

Hello together,

since I got this problem now too and this problem is persistent since many years (from minimal 8.x to current 18.1.27.30), I just had a look at this problem.

 

In my case the WheelScrollLines get changed to 1 when I use the trackpoint scrolling, and will be reset back to 3 when using Trackpad scrolling. It's very annoying when you undock, use the trackpoint and redock, and the mouse wheel of your external mouse will burn.

 

I found a workaround to prevent the Touchpad from changing the setting at all.

 

I was not able to find something with Regmon or even a complete registry-dump, but it seems the driver at least checks the policies if a change is allowed (nice, it looks for permission but don't ask if it's even wanted).

 

To prevent the WheelScrollLines change from ANY software for any user on the current computer (including windows-settings), insert the following registry-file Be sure you selected 3 WheelScrollLines BEFORE using the registry patch.

 

 

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Control Panel\Desktop]
"WheelScrollLines"=dword:00000001


 

To undo this operation delete the key or use the following registry-file:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Control Panel\Desktop]
"WheelScrollLines"=-

Hope Lenovo will give an option to change this misbehaviour.

 

Now I only need a solution for the problem, that with trackpoint scrooling some programs (Notepad++ and some more) does not scroll.

 

Ok, revert. After a restart there was no scrolling possible. Neither with the touchpad, nor with trackpoint. So I stroke all out.

I was wondering what conditions would cause the driver to change the number of lines scrolled.

Still would like to see a fix, though.

Re: Vertical scrolling got reset everytime I use Ultra Nav to scroll vertically

Hello together,

next day, next try.

I think now I got it. After some profiling I went through a lot of data.

Unfortunately I still don't know how the WheelScrollLines settings gets altered.

But there is a hidden registry-key to disable the one line scroll.

 

You can use the following registry-file:

 

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Synaptics\SynTPEnh]
"ForceWheelMouseScrollOneLine"=dword:00000000

I've checked it a few times. When the registry setting is present, the lines won't be reduced to 1 when using trackpoint scrolling. After I removed the settings, it got reduced again.

And now I was still able to scroll, even after a system restart :)

 

I don't know why Synaptics don't gives the user the option, to change this. This problem persist since a lot of years (at least from version 8.x to current 18.1.27.30).

I've tested this option with the current 18.1.27.30 from the W541, but I think the registry-file can modify the behaviour of older versions, too.

 

Two problems solved (Touchpad switch to 3-button one and this annoying one line scroll), one more to go.

I hope trackpoint-scrolling in Notepad++ and other apps will be available.

 

See you,

Markus

I'm running Windows 10 and having the exact same issue, on the same laptop (T450s).  As soon as I logout of Windows or restart the computer, the setting gets changed back to the default.
