amd gpu but display on intel integrated graphics
- by pitseeker
On my Ubuntu 12.04 I connected my monitor to the onboard intel graphics.
I'd like to use my ati radeon 6770 for opencl tasks (e.g. bitcoin mining).
So far I couldn't figure out how to get the ati driver working. When calling "aticonfig --initial -f" it always writes a new xorg.conf that ignores the intel graphics. At boot time it works only when I attached the monitor to the ati card.
So I manually tampered with the xorg.conf and got this:
Section "ServerLayout"
Identifier "Default Monitor"
Screen 0 "myscreen" 0 0
Screen 1 "deadscreen" RightOf "myscreen"
EndSection
Section "Module"
EndSection
Section "Monitor"
Identifier "Default Monitor"
Option "VendorName" "Monitor Vendor"
Option "ModelName" "Monitor Name"
Option "DPMS" "true"
EndSection
Section "Monitor"
Identifier "null Monitor"
Option "Enable" "false"
EndSection
Section "Device"
Identifier "Intel Integrated Graphics"
Driver "intel"
BusID "PCI:0:2:0"
Screen 0
EndSection
Section "Device"
Identifier "aticonfig-Device[0]-0"
Driver "fglrx"
BusID "PCI:1:0:0"
Screen 1
EndSection
Section "Screen"
Identifier "myscreen"
Device "Intel Integrated Graphics"
Monitor "Default Monitor"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
Section "Screen"
Identifier "deadscreen"
Device "aticonfig-Device[0]-0"
Monitor "null Monitor"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
EndSubSection
EndSection
I think this might be the right way since I see that X tries to start both drivers in /var/log/Xorg.0.log.
However the fglrx driver seems crash (end of xorg.0.log):

I'd be very happy if someone can give me a hint on how to configure my ATI card while using the integrated graphics for display.
Update
I used most of jjhughes57 config and successfully booted the X server on intel (keyboard layout is changed though, funnily).
Unfortunately the 2nd X server (fglrx) doesn't fully start. It shuts itself down right after starting

Thanks for any hints what is wrong here.
