Dual screen accelerated X11 (fido)

Dual screen accelerated X11 (fido)

[Sumedha Widyadharma]

Hi,

I currently have a dual-screen X11 setup (LVDS + HDMI) running on a imx6qsabresd,
built using fsl-community-bsp (fido), synced today.

My u-boot video args are:
video=mxcfb1:dev=ldb,LDB-XGA,if=RGB666,bpp=32 video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24,bpp=32
Other than that I use the stock u-boot setup for now.

In my xorg.conf I have two 'Device' sections using the 'vivante' driver for fb0 and fb2.
The server comes up and I can start applications (e.g. matchbox-terminal) on :0.0 and :0.1.
(xorg.conf: https://gist.github.com/anonymous/518d79c4cbfc49b5f672)

I can also run glmark2-es on :0.0.

Trying glmark2-es2, or eglinfo-x11 (I guess anything using DRI) on :o.1 crashes the X-server.
Which isn't surprising as the server logs this:

[...]
218 [4284851.510] (EE) [drm] Could not set DRM device bus ID.
219 [4284851.510] (EE) VIVANTE(1): [dri] DRIScreenInit failed.  Disabling DRI.
[...]
(Xorg.0.log: https://gist.github.com/anonymous/2b0e3b20cbd1d818c48d)

My questions:
- Is there something wrong with my setup?
- Is there any way to get OpenGL/EGL applications to run on both displays using X11?

FYI:
I can use both displays when using wayland.

Regards,
Sumedha Widyadharma

No, under X11 you just get one display.

and for now wayland seems your only hope for dual display. this
question have been asked before(include me :D ).
You may want to dig in the mail list archive to see another's answer for that.

Thanks.
I feel like I read 'the internet' trying to get a definitive answer to this.
I didn't really trust answers regarding older releases to still be current.

I also had hopes that updated vivante drivers might have improved the situation.
I've only seen the 5.x version number for vivante related packages very recently.

So the only way to get this to run is for Freescale to release an updated vivante driver supporting this setup?
Have you had any luck running xwayland?
