Fusuma not working on Ubuntu 18.04

  • 772

I have Ubuntu 18.04 on Dell Vostro 15 - 3546.

uname -api

Linux vaishnavi-laptop 4.15.0-117-generic #118-Ubuntu SMP Fri Sep 4 20:02:41 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

I followed this post to install fusuma. Then when I run sudo fusuma:

I didn't miss any step nor did I close the terminal, but still touchpad gestures don't work!
Thanks in advance.

  1. As per this post, when you run fusuma with sudo the config file is not properly (whatever that means) read. You have to run it as your regular user. I am not sure in which cases using sudo would work or not. As per the voting of the answer you linked, it does work in many cases.

    Note that in a post by the developer of fusuma, it is started without sudo. It is worth reading that post, since it mentions a couple of points that may be crucial:

    1. You "need to log out and log in (or restart) from X".
    2. fusuma -d keeps it running in the background when the terminal is closed.

    Consistently, in the Github readme page, which contains the installation instructions linked in the answer you linked, fusuma is also run without sudo. I wouldn't know why the answerer Rachit Kinger uses sudo.

    You can take advantage of libinput debug-gui in this or other occasion, as also mentioned in that same thread.

  2. Best Answer

    Looking at the output you have attached here, I think the fusuma is configured successfully actually. Here I'm attaching my output file. and after this i tried to use my gestures and it works completely fine. Here is the screenshot.

    So, in your case maybe you haven't followed the tutorial carefully or it may be that your dependencies are not completely installed or you haven't configured your config.yml file.

    I suggest you to again go through that complete process or check your config.yml file first, Moreover you can just install all the dependencies like

    $ sudo apt-get install libinput-tools  
$ sudo apt-get install xdotool 
$ sudo apt install ruby  
$ sudo gem install fusuma

    And now one more suggetion you can try is that first you find your default path of fusuma and run that from there like.

    $ whereis fusuma

    let's say the output will be something like /usr/local/bin/fusuma (this is in my case)

    and run this like

    $ sudo /usr/local/bin/fusuma

    also you can try to run this as without using sudo privileges, maybe it is causing some issue, but I'm not completely sure about this.

    Hope this may help.

  3. Please paste output of $ libinput debug-events with 3 finger swipe.

    If you find lines related to swipe in logs, fusuma can detect gestures.
