OK. Next step is to check if the kernel can see the middle button. To do that, please:
sudo apt install evtest sudo evtest Then select your mouse and click the middle button. Does the tool show events from BTN_MIDDLE ? Also what does evtest list as "Supported events" for the mouse when you first start evtest? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1893638 Title: X forgets middle mouse button exists To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1893638/+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
