Hi,
I’m having an issue getting xwayland to start on a rock5b (aarch64, mesa panthor) device running Gentoo. I just wanted to check if anyone could point an error on my part before I report a bug about this.
When plasma starts, I get the following error in the logs:
Nov 16 11:13:44 rock5b kwin_wayland_wrapper[1093]: kwin_wayland_drm: Could not create a non-master DRM fd for leasing! Permission denied
Nov 16 11:13:44 rock5b kwin_wayland_wrapper[1093]: error marshalling arguments for drm_fd: dup failed: Bad file descriptor
Nov 16 11:13:44 rock5b kwin_wayland_wrapper[1093]: error in client communication (pid 1093)
Nov 16 11:13:44 rock5b kwin_wayland_wrapper[1164]: (EE) could not connect to wayland server
This is the versions I am using
[IP-] [ ] kde-plasma/kwin-6.4.5-r1:6
[IP-] [ ] x11-base/xwayland-24.1.9:0
[IP-] [ ] media-libs/mesa-25.2.7:0

crw-rw-rw- 1 root render 226, 130 Nov 16 11:13 renderD130
Everything else seems to be working fine, except that all applications requiring X11 just hangs as xwayland is not running.
I tried to force the use of the 3 reported cards one by one manually using the KWIN_DRM_DEVICES env variable to no avail (only card0 works at all for the master kwin)
Thanks!
