Xorg log
I have just bought a 3rd monitor, successfully hooked up via Display Port to
the R9 290X (Tahiti XT) card and configured fine as 3 non-mirrored outputs in
XFCE4.
I found that when I turned it off for ~10 seconds or more, after turning it
back on all screens would go black and appear to reinialise. XFCE4 gets
confused and clones the primary monitor output to the new 3rd screen, fiddling
in the XFCE4 Display program fixes this (after the problem happens it seems to
put the primary and new monitor on top of each other...).
Looking into Xorg.0.log, when I turn the monitor off for less than 10 seconds,
I just get the following event:
===============================================================================
[ 512.737] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Invalid
argument
===============================================================================
Being off for 10 seconds or more results in:
===============================================================================
[ 1891.671] (II) RADEON(0): Allocate new frame buffer 3840x1200 stride 3840
[ 1891.677] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Device
or resource busy
[ 1891.678] (WW) RADEON(0): flip queue failed in radeon_scanout_flip: Device
or resource busy
===============================================================================
It now makes sense why monitor output appears to be mirrored (only 2 unique
outputs) - 3840 is 1920*2. When I fix the configuration with XFCE4, the correct
frame buffer is set up:
===============================================================================
[ 2001.120] (II) RADEON(0): Allocate new frame buffer 5760x1200 stride 5760
===============================================================================
I have attached the X log.
I'm currently running Devuan Testing (based off Debian Testing)

Thanks for any help.</pre>
