--- Comment #25 from James <james at nurealm.net> ---
Sorry - I don't seem to have been on the CC list.  I just tested this Sunday,
July 22.

I am running with the mkkot Arch Linux package, xf86-video-ati-git,
1:18.0.1.r12.g3c4c0213-1, 22 Jul 2018.  I have the HD 5570 / Redwood PRO
running three displays.

Starting lxqt with openbox, the original "Invalid command stream" errors are
not seen, but I still see:

 kernel: radeon 0000:05:00.0: No GEM object associated to handle 0x0000000C,
can't create framebuffer
 kernel: radeon 0000:05:00.0: No GEM object associated to handle 0x00000400,
can't create framebuffer

The 1st display will receive sync, but the screen is black with no cursor, and
the 2nd and 3rd displays receive nothing and go to suspend.

Repeatedly stopping and re-starting lxqt seems to always produce the same
result, where before, sometimes the screens would light, with various kinds of
display corruption, in addition to the the black screen result described.  Now,
just the black screens.

I can run weston and kwin_wayland, but the regular X11 server is unusable.
