weston-launch -u as root

If I try to start a weston instance by using weston-launch, while gdm on X is
running I get the following kernel message :

[di mrt  3 09:39:01 2015] [drm:radeon_cp_getparam_kms] *ERROR* invalid ioctl
with kms radeon_cp_getparam_kms
[di mrt  3 09:39:01 2015] [drm:radeon_engine_reset_kms] *ERROR* invalid ioctl
with kms radeon_engine_reset_kms

weston-launch refuses to run, attached a log of its debug output.

kernel - 3.19.0
libdrm - 2.4.59

RS780

weston/wayland 1.7

Maybe unrelated, but there seems to be issue initializing given gfx chip when
running anything non X.

On a fresh boot trying to run any wayland session (weston directly or current
stable gdm) results in just a black screen. No obvious error in the logs.
Booting with plymouth enabled also just results in a black screen.

However when X is started first any subsequent wayland session shows just fine.

Have you tried weston-launch the right way?

That is, have weston-launch setuid root, then in a text mode VT, running
'weston-launch' without any arguments as a normal user?

Though, given your other problems, I don't expect that to help.

Also, sounds like you build weston with ./configure --with-cairo=gl or glesv2.
As GL clients do not work (weston-desktop-shell crashing - that's probably yet
another bug as the fallback fails), this causes the desktop (panel, wallpaper)
to never come up, so you are left with a black screen also for that reason.
Using the default --with-cairo=image would remove one "moving part" from the
equation.

I'd expect people to ask for a full kernel log from boot up to and including
the problem.

Cairo with image backend makes no difference. I actually have no text console
either, but I'm pretty sure I run weston the right way. Weston and gdm
(wayland) run just fine, but just don't show up on the screen.

I actually think it's a general problem with initializing, since I have no text
console as well or plymouth splash if enabled. The machine is usually connected
trough HDMI to a nobrand HD720 TV. When I connect the same setup through VGA it
does give an image (however the image is positioned wrong). I explicitly
disable the VGA output when using HDMI trough the kernel command line :
 video=HDMI-A-1:1280x720@60 video=VGA-1:d radeon.audio=1 radeon.modeset=1
radeon.dpm=1 .

The weird thing is that if I start X it does show up and subsequent runs of
weston or gdm on wayland are just fine, so it just happens after a fresh boot.

Attached 2 more logs with drm.debug=0xe, one for a boot with HDMI and one for
boot with VGA into gdm on wayland.

By the way, the invalid ioctl message in #1 disappeared since switching to the
4.0 kernel.
