Hi everyone, I thought I'd send a bit of spam to see who else might be grappling with a Gnome-3 bug that causes display freezes on pen+touch systems when the pen and touchscreen devices get used simultaneously (e.g., hand on screen while writing). This seems to at least affect Thinkpad Yogas with Fedora 22, and perhaps some others too.
Anyway, this has been reported as a bug against Gnome Shell (https://bugzilla.gnome.org/show_bug.cgi?id=753527) even though I'm not 100% sure whether it's Gnome Shell or some other component that's causing it. If like me you are desperate for a quick workaround so that you can actually use your Yoga with F22 or other affected distributions (are there any? is this a Fedora-specific issue? are other models affected or is this specific to the Thinkpad Yoga?), there's a temporary fix. I just wrote a small tool that disables the touchscreen when the wacom pen reports proximity to the screen. It's only had a few hours of testing so far, so use at your own risk. http://math.berkeley.edu/~auroux/software/xnohands.tar.gz (installation instructions for common use scenario are included in README file) This doesn't fix the underlying gnome-shell issue, of course, and you'll still notice gnome-shell freezing the display when using the touchscreen and a touchpad/mouse/... (anything other than a wacom pen, really) at the same time -- but I don't see any compelling reason to want to do so. This might also be useful to anyone who's lamenting the lack of "pen disables touch" feature OS-wide (at least I don't think there's one) -- it's always annoying to hit something important with the wrist while writing in xournal and end up closing windows or doing other stupid stuff by accident. Feedback welcome.
