Hi, I am nowhere close to getting those 3 lines you mentioned in the trailing mail.
Also note that, my $WAYLAND_DISPLAY variable is set to wayland-0 and $DISPLAY is set to :0. Is that alright? I am once again attaching my weston logs here for your analysis. Please let me know how to get those three lines in the log, as in, how should I make Xwayland spawn as a separate pid. Right now I am not getting any trace of Xwayland in "ps -ef" or anywhere else. The only silver lining I see here is the log "xserver listening on display :0" in weston.log ------------------------Weston log start------------------ Date: 2019-12-12 IST [12:06:24.838] weston 2.0.0 http://wayland.freedesktop.org Bug reports to: https://bugs.freedesktop.org/enter_bug.cgi?product=Wayland&component=weston&version=2.0.0 Build: 1.99.94-2-g4c4f13d configure.ac: bump to version 2.0.0 for the official release (2017-02-24 16:19:03 -0800) [12:06:24.838] Command line: weston --idle-time=0 [12:06:24.838] OS: Linux, 4.14.79-ge669d52447, #1 SMP PREEMPT Fri Nov 29 11:48:31 IST 2019, armv7l [12:06:24.843] Using config file '/etc//weston.ini' [12:06:24.877] Output repaint window is 7 ms maximum.

You already tried them, and I can't see anything wrong in what you wrote. Except, you didn't say Weston logging a message where it actually succeeded in launching Xwayland. Something like this: [12:08:05.666] xserver listening on display :1 ...
