if I turn Randr on it makes no difference, tried:
xrandr --output DFP3 --auto --left-of DFP4
(proper names of the displays according to xrandr)
but it does nothing, so does trying to do it with grandr, the GUI front-end
Topic: OpenCL only seeing one GPU whilst using Multi-Desktop - page 2. (Read 4720 times)
Try adding this to your xorg.conf:
Code:
Section "ServerFlags"
Option "RandR" "on"
EndSection
Option "RandR" "on"
EndSection
Hmm... Openbox should maximize to one screen by default.
What's the output of this command?
xdpyinfo -ext XINERAMA | grep head

really appreciate all the help so far guys. I feel like there is a workaround close but I can't quite get it.
Probably not the solution you prefer, but... http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=146804
I have openbox, so I could enable the compiz extension and try but it won't be compiz-fusion like you get in gnome.

let you know as soon as i get home. there's a single taskbar across the entire 2 screens, which leads me to believe openbox doesn't know there are actually 2 monitors, it's behaving like one big screen.

no i'm using Openbox. I'm on crunchbang, it's a debian based distribution so most ubuntu settings will work, however I don't have gnome or any of the fancy gui's.
Remove the xinerama option.
I assume you're using Unity?
If you install the package compizconfig-settings-manager and then open the settings manager (themes and tweaks -> CompizConfig Settings Manager), you can go to:
Window Management->Place Windows
Try playing with the multi output mode option - see if you can get the effect you want.

i added
Option "Xinerama" "on"
in server layouts, it creates the 'desktop' I was looking for (though for some reason my wallpaper disappeared)
except now only one miner is seen by openCL,

any ideas on having them both be separate screens, but connected, like it would be in windows with multi-display?
You could try turning on Xinerama, by adding this line to ServerLayout:Option "Xinerama"
Might help.
OK this is weird. I added:
Screen "aticonfig-Screen[1]-0" LeftOf "aticonfig-Screen[0]-0"
to my dual-head xorg (in the ServerLayout section) and I get a single BIG desktop stretched across 2 monitors. WITH BOTH GPUS RECOGNIZED BY OPENCL
it's closer to what I was hoping for, but when I maximize a window it doesn't behave separately, the window stretches across 2 monitors.

am i supposed to be sudo when i export the display?
i know the xorg.conf's look deceiving, but I assure you the first setup is cloned and the second one is dual-display. They were both generated using
aticonfig --initial -f --adapter=all (this gives me the first one)
then if i reboot, and go
sudo amdcccle
and set it up to be multi-display, I get the second one. Both GPU's are only seen in the first xorg. I followed so many guides and got to the same conclusion with everything, tried all different version of OpenCL.
I'm convinced it's something I'm missing in the xorg.conf. so anybody on linux with more than one GPU and a dual-monitor setup please take a look and help me out, I'd really appreciate it.
Umm, in your post, you say that the first config is cloned mode, but reading the configs, it looks like the second is cloned mode...
Anyway, in that guide, are you doing the part where he types:
export DISPLAY=:0.1; aticonfig --pplib-cmd "get fanspeed 0"
to get the fanspeed? Or changing the DISPLAY variable at all for that matter?
If you are, you need to make sure you set DISPLAY back to :0 before mining, or only one card will show. You can do this like:
export DISPLAY=:0
Does that help?

thanks for the response, you're right, changed!
You should probably correct the title of your thread as Linux is quite clearly seeing both GPUs.
Your issue is more like 'OpenCL only seeing one GPU whilst using Multi-Desktop'. Whilst I don't know the fix, using the correct title will probably attract the attention of the people who will know and/or be able to test solutions for you.

aticonfig shows both of my cards.
this is the issue i seem to be having:
I can clone displays(single desktop), in which case both GPU's work for mining. this is the xorg.conf for that:
I can have a multi-desktop (xinerama still disabled). but only one GPU is seen by the miner. Here's the xorg.conf for the this scenario:
what i would like to be able to do is have a multi-desktop (2 monitors where I can drag windows between them, not cloned) and have the miner recognize both GPUs. i'm willing to try anything guys. thanks!
