btnx startup

[oliwa7]

Hi,

I am having trouble successfully installing btnx. There are no errors after ./configure, make or make install, however once I run 'btnx' I get the error below.

btnx: uinput modprobed successfully.
btnx: Could not read the config manager file: No such file or directory
Segmentation fault (core dumped)

I am running a fresh install of Ubuntu 18.04.

Any help would be much appreciated.

Many thanks.

@oliwa7 Have you been able to resolve this? I'm getting the same error

After playing around with it a bit today, I have been able to identify and resolve the issue. The problem was that I'm using Wayland, which by default doesn't support running GUI applications such as btnx-config as root.

To circumvent this, I temporarily allow the root user to access the local user's X session by running

xhost +si:localuser:root

Then I run btnx-config with sudo and configure my mouse

sudo btnx-config

Finally, after closing btnx-config, I revoke the root access with

xhost -si:localuser:root

@jgierer12 What distro and version of Linux are you running? If there are additional configuration steps necessary, I would like to document them.

I have been running Ubuntu since at least 18.04 where Wayland was default. I have not needed to make any xhost changes.

The only major change I had to make was starting to use from command line:

sudo btnx-config

Instead of kdesu. I have tried to note this in the documentation on this github when I became aware of the underlying permissions and privilege elevation changes going on.

Can you post your configuration files, including the file path and file name you are using for the configuration file?

Is there any more to your error log?

What is the mouse you are trying to use with BTNX, by the way?

I mostly maintain BTNX for older mice. There is a more active newer application called Piper which is better for most modern mice. https://github.com/libratbag/piper

I only use BTNX when the mouse is not supported by Piper anymore.
