Per https://bugs.freedesktop.org/show_bug.cgi?id=111122#c25 it seems that Lenovo released a BIOS update (1.54 / R0UET74W) to fix IVRS tables on E485. As the Ideapad 330S-14ARR and 530S-14ARR use the same mobo, I guess it is also fixed there (or going to be fixed soon).
Will the BIOS fix interfere with the kernel patch? ** Bug watch added: freedesktop.org Bugzilla #111122 https://bugs.freedesktop.org/show_bug.cgi?id=111122 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795292 Title: ELAN469D touch pad not working To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1795292/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
