Hi
We have 3 workstations running under RedHat Enterprise 7.4, each of them having a few K6000 graphic boards.
The configuration is relatively complex since the workstations are used for visualization on a monitor of approx. 6700mm x 2300mm. Since RANDR did not adjust the screens correctly, we did it manually - I am posting the xorg.conf below.
Everything was working fine, until driver version 384.90 was released. Since then, the screen is black. If RANDR is enabled again, the screens show up, but in an incorrect sequence. Disabling RANDR as we used to do all the time, now gives a black screen (with all 3 workstations).
Our guess is that now RANDR must be used and without RANDR it does not work anymore. Is this correct? Can this be changed again or is there a way to fix this problem?
It worked ever since we installed and configured the system, but now there is now way we can use the system anymore.
Thanks in advance
David
