Hey peoples!
I need a guide on how to get two 7970s mining under ubuntu/xubuntu... There are a few guides out right now but they don't really work, or something is missing, they are untested, and I'm having a lot of trouble with it.
Pleeaaasee point me in the right direction!
Do not use hardware Crossfire.
Install AMD SDK
first:
http://developer.amd.com/sdks/AMDAPPSDK/downloads/Pages/default.aspx#oneThen install AMD 12.3 driver (I've read that 12.4 is slower, dunno if it's true for mining too).
Download the driver from AMD, and then follow this guide (
Manually installing Catalyst...):
https://help.ubuntu.com/community/BinaryDriverHowto/ATIAfter installing, run:
$ sudo aticonfig --adapter=all --initial -f
which will write a (semi) proper /etc/X11/xorg.conf.
If you have just one monitor, edit /etc/X11/xorg.conf so that the first stanza is:
Section "ServerLayout"
Identifier "real desktop"
Screen 0 "aticonfig-Screen[0]-0" 0 0
Screen 1 "aticonfig-Screen[1]-0" 3000 3000
EndSection
This way you put the second screen far away from the first one, so that your mouse pointer will stay bound to the first one and will not disappear beyond the right side of your monitor.
If you use Gnome (I use the fallback session), there's an old old bug, which is a real PITA.
Gnome panels (the bars U put icons and stuff onto) go on the second screen, which U cannot see 'cause there's no monitor attached.
So install cairo-dock, if U like, and live happy with that.
Install java or python or whatever you need for your mining software. However I strongly suggest cgminer:
https://bitcointalksearch.org/topic/official-cgminer-mining-software-thread-for-linuxwinosxmipsarmr-pi-4110-28402Beware: python-pyopencl has a false dependency from nvidia-current (it had till Oneiric, at least).
So, if U need it, download (not install!) python-pyopencl, edit it and remove the false dependency, following this procedure:

$ sudo dpkg -i python-pyopencl.deb
or using gdebi (if it's not installed, sudo apt-get install gdebi).
HTH.
