never ever disable all outputs, it makes Qt go boom. Sorry about that, it's unfortunately nothing we can do about. There is a patch being worked on for Qt 5.6 to make this work again. I do hope it gets integrated.

This should work as expected: xrandr --output DisplayPort-0 --auto --output DVI-0 --auto --left-of DisplayPort-0 Please however notice that disabling all screen blows Qt5 *for sure* - there's no guanrantee that random other RandR events do not cause segfaults as well :-( @Martin, does that mean they finally consider to introduce a dummy screen for 5.6? > @Martin, does that mean they finally consider to introduce a dummy screen > for 5.6? yes, see https://codereview.qt-project.org/138201 |
