Thanks for your report. Odd mouse behavior has reasonably nothing to do with im-config. Changing the affected package to gnome-shell for now.
If you need help to fix your desktop, this is not the right place. This is a bug report. Please ask for support instead at e.g. <https://askubuntu.com>. (But maybe you'd better try a fresh install of 17.10 instead...) ** Package changed: im-config (Ubuntu) => gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1730174 Title: [artful] Mouse broken after upgrade from 17.04 to 17.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1730174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
