I dusted off (literally) my Logitech Marble trackball to replace the Intuos tablet + mouse combination that I was using to cut down on the lateral movement of my right arm which led to back pains.
Not that you care about that one bit, but that meant that I needed a way to get a scroll wheel working with this scroll-wheel less trackball. That's now implemented in gnome-settings-daemon for GNOME 3.16. You'd run:
gsettings set org.gnome.settings-daemon.peripherals.trackball scroll-wheel-emulation-button 8
With "8" being the mouse button number to use to make the trackball ball into a wheel. We plan to add an interface to configure this in the Settings.
Touchscreens
Touchscreens are now switched off when the screensaver is on. This means you'll usually need to use one of the hardware buttons on tablets, or a mouse or keyboard on laptops to turn the screen back on.
Note that you'll need a kernel patch to avoid surprises when the touchscreen is re-enabled.
More touchscreens
The driver for the Goodix touchscreen found in the Onda v975w is now upstream as well.
