The biggest problem is that we cannot really map to the wl_output in a way that it's useful to the client. Also caused by QtWayland not exposing the wl_output in the native interface. From server side we could send a wl_output resource of that client, but our Qt based clients would not know what to do with them :-(</p>
<p>Given that we need to have the client tell the server for which wl_output it wants to have the buffer. A possibility would be to pass the wl_output as argument to the get_buffer request. But then how would the buffer_ready event indicate for which wl_output it is? Maybe we need to do it like the with org_kde_kwin_dpms_manager. It would require to add another level of indirection. Which is nothing I want as it just sounds too complicated and requires quite some changes to the otherwise finished review here. Le sigh. I wish I had noticed that problem earlier. It's something one only notices when using Wayland in day-to-day with multi-screen setup.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>rKWAYLAND KWayland</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D1231" rel="noreferrer">https://phabricator.kde.org/D1231</a></div></div><br /><div><strong>EMAIL PREFERENCES</strong><div><a href="https://phabricator.kde.org/settings/panel/emailpreferences/" rel="noreferrer">https://phabricator.kde.org/settings/panel/emailpreferences/</a></div></div><br /><div><strong>To: </strong>Kanedias, graesslin<br /><strong>Cc: </strong>plasma-devel, jensreuterberg, sebas<br /></div>
