multiple heads as multiple screens?
I've got a laptop running 5.2 amd64. In addition to its built-in
flatscreen, the display hardware has two other outputs on the back of
the machine, a DE15 ("VGA") and an DVI. xrandr says there are outputs
VGA1, DVI1, and LVDS, and I can use options like --left-of to rearrange
them (though I had to hack on
xsrc/external/mit/xorg-server/dist/hw/xfree86/modes/xf86Crtc.c to get
the maximum virtual display size large enough to be useful). But what
I would really like is for them to be separate X screens - the converse
of Xinerama, kind of.
I've been unable to make this happen. Have I just missed something, or
is 5.2's Xorg really too stupid to do that?
If I run the server with +xinerama, it dies "Fatal server error:" /
"Caught signal 11. Server aborting". (I haven't yet gone chasing that
bug.) -xinerama gives me the same behaviour as the default (which is
weird, because -xinerama is documented as disabling Xinerama, but the
resulting server claims to have it, listing "XINERAMA" among its
extensions, and it's doing Xinerama-like merging of multiple heads into
a single X display).
Seems like a weird sort of regression when the MIT server from way back
when could do it on substantially less powerful hardware. Or is
+xinerama the right thing to do and I just need to figure out why it's
I can provide Xorg.0.log if that would help; I didn't see anything
there that looked helpful to me, but that doesn't necessarily mean all
