I can also confirm that 3.19.0-31.36~RevertsV2 works, it resolves the issue on a Dell XPS13 2015.
I noticed that the issue isn't resolved if I only install the linux- image package, it is only when I also install linux-image- extra-3.19.0-31-generic_3.19.0-31.36~RevertsV2 the issue is resolved. I wasn't aware that installing the extra package was a requirement. The previous version, 3.19.0-31.36~lp1500751Reverts, still exhibit the bug, regardless if I have linux-image-extra for that kernel installed or not. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500751 Title: Cryptsetup Keyboard not working on Xubuntu 3.19.0-30 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/1500751/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
