Description Tom Horsley 2014-03-18 23:36:17 UTC
Description of problem:

The postinstall script in wireshark runs "udevadm trigger" unconditionally. This has (among others) the effect of making every usb HID device on my system look like it was just plugged back in again, losing all the xinput settings.

The only thing I can guess that wireshark wants to do with this is chgrp the usbmon subsystem, which, unless this is the very first time wireshark has been installed, will already be the right group.

Version-Release number of selected component (if applicable):

How reproducible:
Every time I install a wireshark update.

Steps to Reproduce:
1.yum update

Actual results:
All the carefully crafted xinput settings for mouse and keyboard vanish.

Expected results:
No ridiculous side effects from updating wireshark.

Additional info:
I don't know if wireshark is the only package that does this, but it is certainly the only one I've noticed.

Perhaps a --subsystem-match=usbmon option on trigger would be helpful?

Comment 1 Tom Horsley 2014-03-18 23:52:40 UTC
And, in fact, I just tried the experiment of running (as root) this command:

/usr/bin/udevadm trigger --subsystem-match=usbmon

and my mouse settings survived intact :-).
