I recently did a clean install of Debian GNOME and updated from stable to testing. Before updating to testing, I had several GUI settings for my touchpad. After updating, they are gone as shown in the screenshot:
For example, I would expect to find the setting for natural scrolling on this settings page.
Opening this page from the terminal yields the following error message
$ gnome-control-center mouse (gnome-control-center:15084): mouse-cc-panel-WARNING **: Detected synaptics X driver, please migrate to libinput
which indicates that the problem is related to
libinput not being installed.
$ dpkg-query -l '*libinput*' in the terminal shows that
xserver-xorg-input-libinput are installed.
Please note that if you want desktop integration (i.e. ability to configure touchpad via GNOME control center or KDE settings), you need xf86-input-libinput.
xserver-xorg-input-libinput package, which is installed, is built from
xf86-input-libinput referred to by Arch Wiki.
How can I solve my problem so that I get the missing settings back?
