I think the problem is a GNOME 3.28 in Ubuntu 18.04. I tried other Linux flavors such as Lubuntu 18.04 and Mint Sylvia (Cinnamon and Mate) and it works fine.
Unfortunately I can't get any message error using Live USB because everything freeze. ** Package changed: ubuntu => gnome-desktop3 (Ubuntu) ** Changed in: gnome-desktop3 (Ubuntu) Assignee: (unassigned) => Cálcio (calcio-nit) -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-desktop3 in Ubuntu. https://bugs.launchpad.net/bugs/1770406 Title: Ubuntu 18.04 Screen, mousepad and keyboard freezing on ACER ASPIRE 7 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-desktop3/+bug/1770406/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
