Hello, I have a problem with my primary mouse button setting that started to happen after the latest update (2020-11-04). I am using Gnome.
The problem is that I have the primary mouse button set to the right button (left-handed setting) but when I unplug the mouse and plug it back in it switches to the left button (default) even though the mouse setting shows it’s still set to the right button. I also get frequent USB mouse disconnections without unplugging that causes the buttons to switch.
I don’t know how I would go about fixing this problem. I appreciate any help or suggestions from you. Thank you!
I am also facing the same issue when I disconnect my mouse and also after I log in.
@anemr were you able to solve this issue?
No. I am still not able to solve it or find something that will help me to solve it.
I don’t know what’s causing this.
But I found a temporary fix.
First test with the following command to see if the lefthanded mode persists even after disconnecting and reconnecting the mouse.
xmodmap -e "pointer = 3 2 1"
If it solves the problem you may have to add this as an autostart entry for it to persist even after log off/ reboot.
Thanks! I confirm that the setting persists with the xmodmap command after reconnecting the mouse.
Unfortunately, it also applies to the touchpad effectively changing tapping to a right-mouse click.
I found some new information from this Reddit post mouse primary button keeps switrching : pop_os
It might be a bug in Gnome’s Mutter.
