For other platforms only Dual outputs are supported. IvyBridge limitations In order to get 3 screen outputs at Ivybridge you shall use 2 Display Ports + any display with some limitations on modes supported. Haswell limitations Haswell 3-pipes is less restrictive than Ivybridge. You can have 3 screns with * 2 Display Ports + any display * 1 Display Port and 2 HDMI or DVI * 1 VGA and 2 HDMI or DVI and no restrictions on mode combination. Thanks for the info - I had thought it might be a limitation of X - as all three worked when used in pairs. Cheers Fred

As this is a getting to know you thread.
I use OpenBSD in a desktop role.
snapshots on an Intel i5 with a radeon 6950, two screens(my card chokes
on the third screen but I think that is hardware)
I like the one dimensional desktop style setup, that is, spectrwm and
lots of xterms. For what its worth spectrwm has the best multiscreen
support I have seen
I don't use blender every day, but I do find it handy from time to time
(for me 3d printing stuff) The maintainer tends to keep it nicly up to
date, which I appreciate as it looks like it is a bitch and a half to build.
I update the snapshots every couple weeks when I want to try what ever
new stuff comes out of the pipe(*cough*, and libc bumps, *cough*).
One thing I would recommend is to look at login.conf(5) and set the
memory limits to something gratuitous, many of the desktop
applications like to use a lot of memory.
And as far as overall experience, I think obsd is a little slower than
linux(whatever that means) but the simplicity and correctness of the
system(obsd was the first/only system where I feel I understand how the
whole thing works) means I enjoy using it quite a bit more.
So good luck, and I hope it works out for you as well as it did for me.

I'm sure three monitors would work just as well as two :) E17 does
work, I have used it in the past. I play with OpenGL stuff quite
regularly and it is my opinion that the recent drivers for intel and
radeon video devices respectively perform roughly the same here as
they do on freebsd or linux. No formal tests have been done by
myself, strictly subjective experience.

Thanks for the thoughtful response. The move looks promising then.
I'll definitely read the FAQ - thanks for the reminder.
RE: OpenGL:
It's great that it works, but is it taking advantage of the hw, or do

I currently have three monitors connected to my laptop but if I try to
enable X on the third one I'm getting the following error:
port:fred ~ xrandr --output VGA1 --auto
xrandr: cannot find crtc for output VGA1
Thanks Fred.
what happens when you disconnect HDMI1? Does VGA1 light up? I'm
thinking the mobile gpu has 2 active outputs, the LCD built-in, plus
one additional monitor of VGA or HDMI type.
But blender 2.72 is running fine (I wish I new how to use it properly).
It's huge, and the learning curve is steep. I've been using it daily
for a year and still don't know squat...

It is important to note that the GCN/radeonsi Radeons are very different
to the earlier parts. For the 7850/Pitcairn parts there is kernel
modesetting support but no 2D or 3D acceleration because all acceleration
depends on glamor-egl and LLVM. If you're after acceleration for now
it is = Haswell for Intel (excluding Bay Trail) or = Northern Islands
for Radeon.

I currently have three monitors connected to my laptop but if I try to
enable X on the third one I'm getting the following error:
port:fred ~ xrandr --output VGA1 --auto
xrandr: cannot find crtc for output VGA1
But blender 2.72 is running fine (I wish I new how to use it properly).
Output of xrandr and dmesg below if interested.

Greetings All,
I've used OpenBSD in the past to build redundant routers and
firewalls and it was fantastic, but it's been quite a few years
since I've played with it. I've also never used it as my default
workstation. Yet.
I've always used Debian GNU/Linux on my workstations in the past,
but with jessie/sid (and practically all other linux distros) the
direction the linux userspace has taken is a serious turn for the
worst IMO. I am simply philosophically at odds with systemd, and I
would like to stop relying on linux altogether if possible. My
problem is I have specific needs, and it's not clear if I can meet
them running OpenBSD. I'm hoping I can, and someone can share their
experiences with making a similar setup work.
Firstly, I'm running an i7 960 with a PCI-e ATI Radeon 7850 in a
three monitor configuration (2 direct DVI and 1 active HDMI-to-DVI
dongle) using the OpenSource Radeon linux driver @1920x1200 on each
monitor.
Hey, not 100% the same but similar setup on a workstation at work:
Radeon HD4550 using radeondrm and two 1920x1080 monitors:
DisplayPort-0 connected 1920x1080+1920+0
DVI-0 connected 1920x1080+0+0
Also have used multiple monitors on my i5-powered laptop, using its
integrated intelHD video.
I'm using enlightenment 17.6 as my window manager. I use and rely on
I use openbox myself but enlightenment 0.17.5 is an available package.
blender http://www.blender.org a /lot/ with hardware accelerated
OpenGL, and having three monitors is important for my graphics work.
blender is available in packages as well, though I have never used it.
Is anyone running OpenBSD with three monitors? With blender, hw-accel
OpenGL, and/or E1{7,8,9}?
I'm sure three monitors would work just as well as two :) E17 does
work, I have used it in the past. I play with OpenGL stuff quite
regularly and it is my opinion that the recent drivers for intel and
radeon video devices respectively perform roughly the same here as
they do on freebsd or linux. No formal tests have been done by
myself, strictly subjective experience.
Your thoughts, knowledge, and possibly links to more info would be
very greatly appreciated.
Thank You.
I would like to point out that I do follow current, both on my own
workstations and my work workstation :)
The FAQ on http://www.openbsd.org/ is always a good read.
Cheers!

Hey Ryan,
Thanks for the thoughtful response. The move looks promising then. I'll
definitely read the FAQ - thanks for the reminder.
RE: OpenGL:
It's great that it works, but is it taking advantage of the hw, or do
you know if it is sw only? Some posts I've read seem less positive
about that.
Sorry I was not clear, it works with hardware for me :) no software
renderer here! That being said, you mention a rather lofty radeon card,
Jonathan Gray replied with some valuable info there, unfortunately if your
card falls ABOVE the category he outlines, it will be rather unaccellerated
for most useful things at this time. If you have an older radeon card you
upgraded from and are willing to use it in the mean time, that could be
a stepping stone for you.
Cheers!
--ryan
Anyone else have any experiences to share?
Thanks again,

Radeon hardware tends to support more outputs http://xorg.freedesktop.org/wiki/RadeonFeature/#index7h2 Ivy bridge supports three outputs with two of them sharing a clock assuming the sytem has two displayport outputs (and none do?). Haswell is a bit less restrictive still. Quoting https://01.org/linuxgraphics/documentation/3-pipes 3-pipes is a feature that allows users to have 3 Monitors plugged in. It is present at 3rd Generation Intel Core processors with Intel HD Graphics (codenamed IvyBridge) and 4th Generation Intel Core processors with Intel HD Graphics (codenamed Haswell). For other platforms only Dual outputs are supported. IvyBridge limitations In order to get 3 screen outputs at Ivybridge you shall use 2 Display Ports + any display with some limitations on modes supported. Haswell limitations Haswell 3-pipes is less restrictive than Ivybridge. You can have 3 screns with * 2 Display Ports + any display * 1 Display Port and 2 HDMI or DVI * 1 VGA and 2 HDMI or DVI and no restrictions on mode combination.
