Description Peter Hutterer 2008-09-17 19:54:22 UTC

The evdev code can't deal with posting events from rel/abs axes, so abs axes are automatically disabled when a relative axis is detected. This can be fixed in evdev's ReadInput.

un-duplicating. Even with Bug 23126 fixed we still don't support both axes on the same device, only either-or.

Comment 3 Peter Hutterer 2009-10-08 19:28:56 UTC

slightly improved now by the IgnoreRelativeAxes and IgnoreAbsoluteAxes in evdev 2.3.

Comment 4 Peter Hutterer 2016-10-26 05:48:06 UTC

libinput will handle this where required
