With Emmet's help (thanks for that!), I tested 1.5.6-0ubuntu1, and unfortunately it did not fix the problem.
In summary, the gamepad axis' (two analogue thumb controls and the 4/8-way directional pad) works fine until I try to calibrate it in jscalibrator. Then the axis's stop working. They start working again by pulling out the gamepad usb cable, and then reinserting it. I also tried calibrating with jscal, and that appears to work fine. -- Gamepad axis not working after calibration https://launchpad.net/bugs/81093 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
