Bug#905248: gnome-shell: "Second" mouse middle click scrolling not working properly

Thu Aug 2 02:37:19 BST 2018

Package: gnome-shell
Version: 3.22.3-3
Severity: normal
Tags: upstream

Dear Maintainer,

I am filing this against gnome-shell as it seems to be the most logical
candidate (probably handles mouse, but it could be just xorg). I also marked it
upstream as that is probably where the bug resides in either case.

Using Stretch GNOME v3.22 with X.Org server v1.19.2 on a Lenovo ThinkPad T61,
the TrackPoint (the red dot -- pointing stick on the ThinkPad keyboard) is
obviously detected as a mouse (discernible from GNOME settings). Using a
separate ("real") wireless mouse, which is probably treated as a second mouse,
clicking and holding the middle mouse button in Firefox or in Libreoffice does
not properly drag-scroll the page. This does work properly with the TrackPoint
middle button. The "real" mouse's middle button does work properly in cases
like middle-click-to-new-tab in Firefox or middle-click-to-copy in other Apps,
just not when it is held down.

As I mentioned, I am not sure where the problem resides, but it is not just app
related, since I noticed it in multiple apps. So it must be the window manager
or xorg.

Many thanks if this gets pinned down and resolved.
