Comment 32 for bug 1725384

This bug seems to only affect Xorg. Wayland is not affected (see https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1725384/comments/18).

Since Xorg is not a priority, I suspect this bug is not getting attention.
Unfortunately, many of us have to use Xorg (if you have Nvidia hardware, for example).

Initially, I thought that perhaps Gnome is generating multiple touch events, causing the apps overview to open, and then close again (see https://bugs.launchpad.net/ubuntu/+source/gnome-shell-extension-ubuntu-dock/+bug/1725384/comments/10).

However, this could be an issue in Gnome Shell, Gnome Dash, Xorg, specific hardware, or something else entirely.

Let's see if we can narrow it down or find some kind of pattern, or clue, to what is going wrong.

Doing this may help provide the developers with enough information to spot the cause and fix this bug.

It would really useful for all of us to list the hard ware we have...

Please share the output of:

(1)
$ sudo dmidecode | grep -A9 "System Information"

(2)
$ sudo lshw -short

(3)
$ lspci

(4) Is the multi-touch module loaded (most likely for all of us)...
$ lsmod | grep multi

(5) Multi-touch module version number...
$ modinfo hid_multitouch | grep version
