@hendwolt Thank you for the report, could you check your wayland supports wl_data_device_manager
interface?
Might be a simple missing NULL
check when accessing that.
@akallabeth might also be the announce of global object that aren't done in the order that we expect.
@hardening true.
@hendwolt can you give a try at https://github.com/hardening/FreeRDP/tree/ddm_fix ?
@hendwolt it has been merged upstream.
@hardening looks like we missed something else, added a patch in #5213
@akallabeth
How can I find out if my wayland supports it?
In the file wayland.xml on my system I find this snippet:
interface name="wl_data_device" version="3" description summary="data transfer device" There is one wl_data_device per seat which can be obtained from the global wl_data_device_manager singleton. A wl_data_device provides access to inter-client data transfer mechanisms such as copy-and-paste and drag-and-drop. /description
Is this enough?
@hendwolt yes, that is enough. Found the remaining issue and a fix is in #5213 along with some graphical glitch stuff.
The Wayland client from the current master segfaults on Plasma5 on Wayland. Even without any parameters wlfreerdp segfaults.
