Need support to have weston randr release
Hi all, I have a Linux system based on weston wayland and I need to get the current setting of the display resolution. Unfortunately, xrandr command does not work on Wayland. After much searching, I came to this information which is about adding weston-randr support for Weston compositor: https://lists.freedesktop.org/archives/wayland-devel/2014-February/013480.html However, I could not find a link to download the patch to apply in order to have weston-randr command Please advise if the patch is available for the community to use. Thank you, Huy
Re: Need support to display application at (0, 0) position on Weston desktop
Hi Daniel, Thank you for the reply. In my application, I want to overlay an MPV video window on another application so that users can view both video content and other application static content so that a fullscreen MPV is not suitable. Is it possible to adjust the initial position of MPV video window at (0,0) on the weston desktop (I already hide the weston top bar).

Hi Pekka, Thank you for your helpful feedback. I understand all your points and will take a look to provide a custom logic to weston desktop to support my use-cases.

Re: Need support to display application at (0, 0) position on Weston desktop
Hi Igor, I do not have a full context about Wayland protocol vs X11 legacy faults to understand the reason why the Wayland devs do not support absolute position decided by client applications. Fortunately, I can modify the weston desktop shell to provide that support to my particular use-case with my local build so that I can live with that until an official support from Wayland in the future.
