Same behavior here. Middle Mouse Button (button2) not working, starting
xev | grep button
try it multiple times; button event occurs; stop xev and the button
keeps working.\
Environment:
KDE Neon (based on Ubuntu 18.04) with mainline kernel verion
5.1.2-050102-generic
Hardware:
Logitech USB-PS
If someone else has those issues with a USB-C Dock (Thunderbolt 3) I got rid of
the issue by using the latest mainline Kernel:
5.1.0-050100-generic #201905052130 SMP Mon May 6 01:32:59 UTC 2019 x86_64
x86_64 x86_64 GNU/Linux
and the following Kernel config settings (/etc/default/grub):
GRUB_CMD
Since I'm also facing this bug I just want to confirm that the error
also occurs on the latest mainline Kernel (5.1) and also on the current
drm-tip kernel version (5.1.0.0994 from https://kernel.ubuntu.com
/~kernel-ppa/mainline/drm-tip/2019-05-05/)
I'm trying to use an additional monitor on my X3
