Found the problem! Somewhere is the bespoke input logic for Unity8 we're assuming the device is (typically) around 100Hz so also generates large motion deltas. That's incorrect. My mouse is configured for 1000Hz so generates small (but many) deltas. You can test this with a sufficiently capable mouse using kernel parameter: usbhid.mousepoll=1.
Removing that kernel parameter fixes the speed. Although we should fix Unity8 because Xorg and Mir's demo servers don't have such problems with 1000Hz mice. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1539009 Title: Mouse cursor moves way too slow in Unity 8 To manage notifications about this bug go to: https://bugs.launchpad.net/qtmir/+bug/1539009/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
