Linux only recognizing one card

[leshow]

I followed this guide: http://forum.bitcoin.org/?topic=7514.0

aticonfig shows both of my cards.


$ aticonfig --odgc --adapter=all

Adapter 0 - ATI Radeon HD 5800 Series 
                            Core (MHz)    Memory (MHz)
           Current Clocks :    800           1000
             Current Peak :    800           1000
  Configurable Peak Range : [800-1200]     [1000-1500]
                 GPU load :    0%

Adapter 1 - ATI Radeon HD 5700 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    400           1200
             Current Peak :    860           1200
  Configurable Peak Range : [600-960]     [1200-1445]
                 GPU load :    0%

It sounds like X isn't running on the second adapter, do 'aticonfig --initial -adapter=all' and then reboot.

i did that a bunch of times and it didnt fix it. i have one monitor plugged on each card and they both work

[leshow]

i wanted to mention i've also got DISPLAY=:0 in my bashrc

bump. please help!

[Grinder]

Try removing
Section "ServerFlags"
   Option       "Xinerama" "on"
EndSection

and if that doesn't work, try removing or renaming /etc/X11/xorg.conf and run aticonfig --initial --adapter=all --force

Also, what does
echo $DISPLAY
say?

[leshow]

OK that worked. but now i can't use 2 displays. I want the "big desktop" thing. how do i do that without xinerama?

[leshow]

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:

Code:

Section "ServerLayout"
	Identifier     "aticonfig Layout"
	Screen      0  "aticonfig-Screen[0]-0" 0 0
	Screen         "aticonfig-Screen[1]-0" LeftOf "aticonfig-Screen[0]-0"

EndSection

	BusID       "PCI:2:0:0"
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[0]-0"
	Device     "aticonfig-Device[0]-0"
	Monitor    "aticonfig-Monitor[0]-0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

Section "Screen"
	Identifier "aticonfig-Screen[1]-0"
	Device     "aticonfig-Device[1]-0"
	Monitor    "aticonfig-Monitor[1]-0"
	DefaultDepth     24
	SubSection "Display"
		Viewport   0 0
		Depth     24
	EndSubSection
EndSection

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!

[leshow]

i'm not sure if this makes a difference but on when i have the two displays on and they aren't cloning each other (multi-desktop setting in amdcccle) there's no background.

[Grinder]

There are various ways to make it work, but I don't know much about it because I don't have any monitors attached to my Linux miners. You can try this: http://ubuntuforums.org/showthread.php?t=221174

Or Google for other alternatives.

[leshow]

thanks, i've been googling and working on it for a few days and haven't had any luck. i'll try the mining support forum since I'm allowed to post there now
