I followed this guide: http://forum.bitcoin.org/?topic=7514.0aticonfig 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: Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen[0]-0" 0 0 Screen "aticonfig-Screen[1]-0" LeftOf "aticonfig-Screen[0]-0" EndSection

Here's the xorg.conf for the this scenario: Section "ServerLayout" Identifier "aticonfig Layout" Screen 0 "aticonfig-Screen[0]-0" 0 0 EndSection
Section "Module" EndSection

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!

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.

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?

[note these were executed using the SECOND xorg configuration (dual monitor, not cloned)] leshow@crunchdesk:~$ export DISPLAY=:0.1 leshow@crunchdesk:~$ sudo aticonfig --pplib-cmd "get fanspeed 0" [sudo] password for leshow: ati_pplib_cmd: Unable to open display `:0.1'. aticonfig: parsing the command-line failed. leshow@crunchdesk:~$ export DISPLAY=:0 leshow@crunchdesk:~$ cd miners/poclbm/ leshow@crunchdesk:~/miners/poclbm$ ./poclbm.py No device specified or device not found, use -d to specify one of the following - Cypress
[1] AMD Phenom(tm) II X4 955 Processor leshow@crunchdesk:~/miners/poclbm$
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.

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.
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.

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,

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.

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.

Hmm... Openbox should maximize to one screen by default.
What's the output of this command? xdpyinfo -ext XINERAMA | grep head

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.

I have openbox, so I could enable the compiz extension and try but it won't be compiz-fusion like you get in gnome.

Try adding this to your xorg.conf: Section "ServerFlags" Option "RandR" "on" EndSection

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

I think the problem is it is only making one display, i see all these examples of exporting DISPLAY=:0 to get to miner to work or exporting DISPLAY=:0.1 to get access to a different display. However my setup seems to only have one display 0.0, I dont have to export for the miners to work and I can't switch to any other one.

You could try changing: Screen "aticonfig-Screen[1]-0" LeftOf "aticonfig-Screen[0]-0" to Screen 1 "aticonfig-Screen[1]-0" LeftOf "aticonfig-Screen[0]-0" It should force your second screen to be identified as :0.1 What's the output of "xdpyinfo -ext XINERAMA | grep head" now? Openbox needs the screen geometry to be exported in the XINERAMA extension's protocol for the maximize on one screen thing to work. RandR provides this functionality, which is why I suggested turning it on. When the command above doesn't show anything, that suggests that there's no Xinerama information available.
