Hi Joseph, My battery ran down. When i plugged booted up everything was working, so it's really intermittent, and the steps to resolve seem to always involve always a reboot (after sometimes several times trying to disable the trackpoint in BIOS, boot in and then enable trackpoint in BIOS and boot in ... but this does not always work), or a suspend. Several kernel versions have had this problem, and so I was sort of starting to wonder if there was some kind of a patch war going on behind the scenes, breaking it then fixing it. It might just be my hardware too, unless we see this from other users. I did initially need to get this trackpad replaced a year ago, and so it might be degrading? As i mentioned, it has also a touchscreen. Idk if this can cause bus conficts. One interesting thing is that when i disable the trackpoint in bios, i can often get the pad itself to show up again and wok, but the buttons won't work. So we've got the touchpad, the trackpad and a trackpoint possibly conflicting? i'd be hesitent to check the upstream kernel for sec reasons, since i work on this laptop, but i can certainly tell you if i see the problem once it gets pushed out. I'll just note that uname -a is currently: Linux x1 3.13.0-74-generic #118-Ubuntu SMP Thu Dec 17 22:52:10 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux and if i see a problem on a later version let you know? thanks for your reply! _d On Fri, Dec 18, 2015 at 3:40 PM, Joseph Salisbury <
