It looks like there are disconnection/reconnection problems with the USB dongle for this mouse in your kernel log. So this might be a kernel bug or it might be a hardware problem.
Please try: * A different mouse * A different kernel like https://kernel.ubuntu.com/~kernel- ppa/mainline/v5.8.5/amd64/ ** Summary changed: - The mouse freezes + Genius Wireless Mouse freezes ** Package changed: xorg (Ubuntu) => linux (Ubuntu) -- 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/1893569 Title: Genius Wireless Mouse freezes To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1893569/+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
