sudo aticonfig --initial --adapter=all
thank you - I have known this and done this xx-times (now I am on xorg.conf.fglrx-64
and it was possible at one time to mine with all three adapters (2*5870 and 1*5830)BUT
if I change with Catalyst Control Center to dual screen (Big Desktop) on next reboot there is only card 0 active again
I have also tried:
sudo aticonfig --adapter=all --initial --xinerama=off
sudo aticonfig --adapter=all --initial --xinerama=on
sudo aticonfig --initial --adapter=all --dtop=horizontal -v -f
sudo aticonfig --initial --adapter=all --dtop=horizontal --overlay-on=1 -v -f
sudo aticonfig -f --adapter=all --initial=dual-head --screen-layout=left
and a few more combinations but it was not possible to get all three cards working AND
a Big Desktop on the 2 Monitors (only clone desktop)
I think that aticonfig and Catalyst Control Center are working poorly together, because if I change something with CCC it changes the number of active adapters too...
Same issue here, running ubuntu 12.04 using a 5970.Dual head/ Disabled 2nd display
GPU0: 100% GPU1: 0%
So far it seems Dual head & disabled 2nd display results in the second GPU not being available.
ADL and OpenCL do not detect the same amount of GPU's in either of these configurations.Cloned
GPU0: 100% GPU1: 100%
If I run in cloned mode (with a resistor being a dummy plug), reconfig the xorg.conf using:
aticonfig -f --adapter=all --initial
Reboot, I get both GPU's working.
ADL and OpenCL detect the same amount of GPU's.
id leave it at this, but unfortunately (from testing so far) I can only set the resolution to 1600x1200 (not the desired 1920x1080).Current
GPU0: 100% GPU1: 50%
Current I set the cloned mode, then manually edit the resolutions (in xorg.conf), reboot and I I seem to get ~50% hash rate on the 2nd GPU and the 1st works normally.
Its my current compromise since I ended up working way to late on this last night.
