Can you also test the following upstream kernel: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.2-rc1-unstable/
If v4.2-rc1 has the bug, we can bisect between 3.19 final and 4.2-rc1. If v4.2-rc1 does not have the bug, we will have to test some of the other 4.2 release candidates(rc2, rc3, etc) to find which one introduced the bug. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1498667 Title: [Toshiba P50W-B00F] Touchscreen no longer working To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1498667/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
