Ronald's solution in #5 fixed it for me - now BTN_7 is no longer propagated to X as a mouse click. Volume buttons keeps working. The Call button (previously BTN_1) stops registering according to xev, but that didn't do anything for me before anyway. (Interested readers may tweak the button ignores to re-enable)
Would #5 be backported to 16.04.4 TLS given End-of-life is 2021? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1581626 Title: Switching to USB sound device stops USB mouse clicks from registering To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1581626/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
