But when I say "come from the server" I really mean the 2D X driver
makes up the name and the server just reports it. And indeed, between
xorg-x11-drv-intel-2.21.15-4 and -9 output naming was changed to include
a dash (if using UXA), which happened because the output setup code was
synced with the version in the generic modesetting driver (which also
happens to match radeon and nouveau). Upstream intel omits the dash for
both sna and uxa still though. And if we were to ever get multi-gpu
randr working the names would destabilize again, since we'd have to move
the %d part of the name up to the core server since you really don't
want two outputs both named VGA-0. And caring about the names is
somewhat futile anyway since what you're usually more concerned with is
the _monitor_, which is why all sane desktops save configurations based
on EDIDs not on output names.
I thought multi-gpu randr was supported in 1.4? I certainly see one
provider for each of the two gpus in this machine, and can see five
connectors across the two with three monitors connected. It looks like
it just adds an extra digit to the connector names on the second card:
DVI-I-1 connected primary 2560x1600+0+0 (normal left inverted right x
axis y axis) 646mm x 406mm
DVI-I-2 connected 1200x1600+2560+0 right (normal left inverted right x
axis y axis) 408mm x 306mm
DVI-I-1-3 connected (normal left inverted right x axis y axis)
HDMI-1-1 disconnected (normal left inverted right x axis y axis)
VGA-1-1 disconnected (normal left inverted right x axis y axis)
The fact that X crashes (BZ#1110273) if I try and rotate the monitor on
the second graphics card means I can't actually use them all, but it
works if I don't try and rotate it.
