Hi! Thanks for the response!
I decided to split the configuration option grab_mouse into two distinct options, enable_mouse and grab_mouse. This change will likely make it into Eruption 0.1.12:
If enable_mouse is set to true, Eruption will process mouse events (the mouse device is opened in "shared mode")
In addition to this, if grab_mouse is set to true as well, then Eruption will be able to inject mouse events (the mouse device is opened in "exclusive mode").
grab_mouse set to true will open the "real" mouse exclusively, hide it from the (input) system, and replace it with the "Eruption Virtual Mouse" device. That means if you want to use other software that needs to access the "real" hardware mouse device, you may want to set grab_mouse to false. This way you will only lose the ability to inject virtual mouse events (no Macros/Easy Shift+), but Eruption may at least process mouse events and show some effects.
Concerning the CPU load, please feel free to open up new issues any time!

Hi! Thanks for bringing this issue to my attention!
I think that your issue is caused by Eruption grabbing your mouse device exclusively.
It is possible to completely opt-out of mouse support by adding:
[global]
# ...
grab_mouse = falseto the main configuration file: /etc/eruption/eruption.conf. (This feature has recently been promoted from experimental.)
Could you please describe in more detail which desired features you lose while using the Eruption Virtual Mouse device? Maybe I am able to fix the root cause then!
It may be the case that you are running another user-mode driver software that wants to grab the device too!?
Then either the driver software or Eruption will fail to open the device.

@X3n0m0rph59 thank you for confirming. It appears I was on the right track.
Last night when I re-read the README.md after filing the issue, I set the grab_mouse parameter before finishing for the day.
$ grep mouse /etc/eruption/eruption.conf
grab_mouse = false
Today I didn't give it much thought about the issue. I just checked the XFCE4 "mouse and touchpad" control panel application and it shows the Eruption Virtual Mouse is disabled and Logitech M325 enabled.
As far as having a potential bug, would some of the following information help?

The only other USB device that I have directly plugged in right now is a Belkin USB hub.
Now I have noticed another issue in the log and have seen what I consider "high" CPU usage, but I thought that should be filed as a separate performance bug/improvement suggestion.
Examples from journalctl -xe eruption of warning messages that I often see repeated multiple times:
Jul 29 00:32:59 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > More than 82 milliseconds of jitter detected!
Jul 29 00:32:59 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > This means that we dropped at least one frame
Jul 29 00:32:59 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > Loop took: 143 milliseconds, goal: 41
Jul 29 00:34:07 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > More than 82 milliseconds of jitter detected!
Jul 29 00:34:07 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > This means that we dropped at least one frame
Jul 29 00:34:07 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > Loop took: 138 milliseconds, goal: 41
Jul 29 00:35:09 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > More than 82 milliseconds of jitter detected!

Jul 29 00:35:09 <HOSTNAME_REDACTED> eruption[848]: WARN eruption > Loop took: 133 milliseconds, goal: 41
Also the eruption process is typically in the top five high CPU processes (between ~2.85-3.35%) according to my conky widget process listing. eruption typically uses more CPU than Google Chrome with 3 tabs open. I have an Intel NUC with a Core i7-5557U w/16GiB RAM and a Samsung EVO SSD.
