Description Peter Hutterer 2014-09-19 00:57:16 UTC

Libinput asserts in a couple of places where things shouldn't happen (or prints a bug warning). In those cases (and some others) it's useful to have an event trace of how we got there.

Simple approach to this would be to store the last X evdev events in libinput and print them (in evemu format ideally) together with the bug message.

incomplete/untested patch for backtracing

Just so it's archived publicly too, this is an initial attempt at the backtrace. Incomplete and untested.

closing for now, reopen if there's a more acute need for it
