In the past few weeks (after an update) my touchpad have been acting weird.

Whenever, I let go of the mouse button the system does not register it until several seconds later. This is particular annoying when scrolling.

I couldn't find anything about this anywhere nor any other people having the same problem...

I know very little about the mouse drivers, so I don't know where to begin.

Here is ls -la of /etc/X11/:

Here is xinput list-props DEVICEID:

Here are the files in /usr/share/X11/xorg.conf.d/:

Here is a pastebin-link:https://pastebin.ubuntu.com/p/M2y7jQcCz6/ to 40-libinput.conf

Here is a pastebin link:https://pastebin.ubuntu.com/p/xfRjhKvnxV/ to 99-libinput-custom-config.conf

  • Could you post `InputDevice` section from the file `/etc/X11/xorg.conf` – Bob Aug 16 '18 at 12:20
  • I don't have such a file... – Thomas Kragh Aug 16 '18 at 12:22
  • Do you have files inside `/etc/X11/xorg.conf.d/` directory? Could you post `ls -la /etc/X11/xorg.conf.d/` – Bob Aug 16 '18 at 12:25
  • I dont' have that folder... I will post ls -la of /etc/X11/ – Thomas Kragh Aug 16 '18 at 12:28
  • Detect your devices first: `xinput list`, find `id` number of your mouse, e.g. `id=10` or `id=7`. Next execute: `xinput list-props 10` - where you have to replace `10` with real `id` number of your mouse. – Bob Aug 16 '18 at 12:33
  • Done, and I changed "mouse" to "touchpad" since i realized this may make a difference. – Thomas Kragh Aug 16 '18 at 12:38
  • Ups think I got the wrong ID changed it again. – Thomas Kragh Aug 16 '18 at 12:41
  • Do you have files in the `/usr/share/X11/xorg.conf.d/` directory? – Bob Aug 16 '18 at 12:46
  • Yes - posted, and I will try and post what I think might be relevant from within the files. – Thomas Kragh Aug 16 '18 at 12:52
  • Post content of `99-libinput-custom-config.conf` and `40-libinput.conf` (please, as text, not a screenshot). you can use a `pastebin` service like this: https://pastebin.ubuntu.com – Bob Aug 16 '18 at 12:56
  • Ok will try and do that below what I just did. – Thomas Kragh Aug 16 '18 at 12:58
  • Sorry, I'm giving up. There are some contradictions in the information you have posted. I understand nothing. – Bob Aug 16 '18 at 13:00
  • Can you tell me what the contradictions are? I understand even less... – Thomas Kragh Aug 16 '18 at 13:04
  • Try to move `99-libinput-custom-config.conf` to your home directory temporarily: `sudo mv /usr/share/X11/xorg.conf.d/99-libinput-custom-config.conf /home/user/` - reboot your computer afterwards and check if problem is solved. – Bob Aug 16 '18 at 13:16
  • I remember now making that file because the touchpad was way to slow - and it is so again after removing it. However, the problem persists so it was not my own meddling... I also tried moving 70-wacom.conf out - no change either. – Thomas Kragh Aug 16 '18 at 13:19
  • I now also tried to plug in another mouse - it does not have the same problem... – Thomas Kragh Aug 16 '18 at 13:21
  • Try to install `xserver-xorg-input-synaptics` package and use this settings for the touchpad: https://pastebin.com/JKhpDn3J – Bob Aug 16 '18 at 13:41
  • Only replace `MatchDevicePath "/dev/input/event15"` with `MatchDevicePath "/dev/input/event*"` – Bob Aug 16 '18 at 13:49
  • Tried that now - problem persists... – Thomas Kragh Aug 16 '18 at 15:50

The reason for delayed button release might be the Tapping Drag feature, which is enabled (by default) according to your xinput list-props output.

The Scroll Methods Enabled might also interfere with the buttons, depending on what the currently-enabled scroll method actually is.

Try xinput set-prop <DEVICE> 279 0 and xinput set-prop <DEVICE> 292 0 0 0 to see if either of them fixes your problem.

  • Tried both (first one then added the other) can see using list-props that the change took effect, but unfortunately didn't fix the problem... – Thomas Kragh Aug 16 '18 at 13:29
