trying to build two 2x2 screens on NVS 810 (8 monitors connected). Found that it’s not possible with one xserver started. Started two xservers and only one of them active at a time and can be switched with ‘chvt’ command. Tried to use -sharevts option and now second server can’t be started:
[ 13895.361] (EE) NVIDIA(GPU-0): Failed to acquire modesetting permission. [ 13895.361] (EE) NVIDIA(0): Failing initialization of X screen [ 13895.363] (II) UnloadModule: "nvidia" [ 13895.363] (II) UnloadSubModule: "glxserver_nvidia" [ 13895.363] (II) Unloading glxserver_nvidia [ 13895.363] (II) UnloadSubModule: "wfb" [ 13895.363] (II) UnloadSubModule: "fb" [ 13895.363] (EE) Screen(s) found, but none have a usable configuration. [ 13895.363] (EE) Fatal server error: [ 13895.363] (EE) no screens found(EE) [ 13895.363] (EE)
Is it possible to overcome this limitation and somehow use two 2x2 screens with NVS 810 (actually I want more from two NVS810 cards in one system, but need to start from something).
