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).<\/p>\n
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.<\/p>\n
So I manually tampered with the xorg.conf and got this:<\/p>\n

However the fglrx driver seems crash (end of xorg.0.log):<\/p>\n

Update<\/h2>\n
I used most of jjhughes57 config and successfully booted the X server on intel (keyboard layout is changed though, funnily).<\/p>\n
Unfortunately the 2nd X server (fglrx) doesn’t fully start. It shuts itself down right after starting><\/p>\n

Solution<\/h2>\n
In my case the solution was quite simple. Mainly the xorg.conf (from jjhughes57) brought me on the right track. The remaining issues could be fixed in \/etc\/lightdm\/lightdm.conf. My final version is:<\/p>\n
[LightDM]\nseats=Seat:0 Seat:1\n\n[SeatDefaults]\nautologin-user-timeout=0\nautologin-session=lightdm-autologin\ngreeter-session=lightdm-gtk-greeter\n\n\n[Seat: 0]\nxserver-layout=seat0\nxserver-command=\/usr\/bin\/X :0 -auth \/var\/run\/lightdm\/root\/:0 -nolisten tcp vt7 -sharevts -novtswitch\nautologin-guest=false\nautologin-user=fx\nautologin-user-timeout=0\nautologin-session=lightdm-autologin\nuser-session=ubuntu\n\n[Seat: 1]\nxserver-layout=seat1\nxserver-command=\/usr\/bin\/X :1 -auth \/var\/run\/lightdm\/root\/:1 -nolisten tcp vt8 -sharevts -novtswitch\nautologin-guest=true\nuser-session=ubuntu\n<\/code><\/pre>\nOne problem was that “\/usr\/share\/xgreeters\/lightdm-gtk-greeter.desktop” was missing. After properly installing lightdm-gtk-greeter again the second X-server came up successfully. Now the following requirements need to be fulfilled:<\/p>\n
\n- X needs to accept connections on :1 (assuming that :1 is your<\/li>\n
- fglrx-display) your user needs permission to open X-clients on :1<\/li>\n<\/ol>\n
Actually I first tried with autologin-guest=false which doesn’t work. With autologin-guest=true and a running user session (as a guest user) you need to disable X access control (that’s the easiest at least). E.g.: on display :0 as root:<\/p>\n
# su - guest-6ht0hq\nguest-6ht0hq$ echo $DISPLAY\n:0.0\nguest-6ht0hq$ export DISPLAY=:1\nguest-6ht0hq$ xhost +\naccess control disabled, clients can connect from any host\nguest-6ht0hq$\n<\/code><\/pre>\nNow on another terminal (as root):<\/p>\n
# DISPLAY=:1.0 aticonfig --adapter=0 --od-getclocks\nAdapter 0 - AMD Radeon HD 6700 Series \n Core (MHz) Memory (MHz)\n Current Clocks : 850 1000\n Current Peak : 850 1000\n Configurable Peak Range : [500-970] [1000-1430]\n GPU load : 0%\n#\n<\/code><\/pre>\n\n- \n
So I am really close to solving this issue. The basic Idead i had was a multi seat session. This allows the ATI card to have its own X session and the Intel display to have its own X session.<\/p>\n
\n- Make sure PCIE is the default display for the system but that your onboard GPU is enabled in your system BIOS<\/li>\n
- Modify our \/etc\/X11\/xorg.conf to look like this…<\/li>\n<\/ol>\n

You either need to connect a monitor to the card or connect a dummy plug. Otherwise, the card plays dead. If your monitor has two connections, you can just connect one of them to the card and not use that input.<\/p>\n<\/li>\n<\/ol>\n
