Is there a wiki page explaining how > to do what you are suggesting? xephyr is x-in-a-window. valgrind is an actual code debugging tool that has zero to do with display. think of it as "gdb on steroids" that makes things run super slow but catches things gdb never could. lucky for you we documented things: https://www.enlightenment.org/docs "debugging (generic) - efl and enlightenment". "enlightenment specific debugging". "efl application debugging" "remote debugging" those are relevant if you want to debug e or any apps using efl. some of the pages cover valgrind explicitly. > On Fri, Jan 6, 2017 at 2:39 AM, Carsten Haitzler <ras...@rasterman.com> > wrote: > > > On Fri, 6 Jan 2017 02:21:10 -0600 Jeff Hoogland <jeffhoogl...@gmail.com> > > said: > > > > > Having some users report segfaults with our E17 fork using the latest EFL > > > under our Ubuntu 16.04 base. > > > > > > Had someone run a back trace and post it here > > > <http://forums.bodhilinux.com/index.php?/topic/14036-moksha- > > segfault/?p=102195>. > > > Looks like it is dying in the EFL somewhere?
