@PHlin Hi, unfortunately, it's not possible to fix this on 12.04.4 as #13 saying.
I will close linux-lts-raring branch as Won't fix. Please you test it on 14.04(same as Bug 1190867, no need?) and close this bug, thanks. ** Changed in: linux-lts-raring (Ubuntu) Status: New => Won't Fix -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1256213 Title: [HP Pavilion14] Touchpad was detected as PS/2 mouse To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1256213/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
