Quadro FX4800 Display Port Issues On Second Screen
I have just read the thread titled:
intermittent failure to detect both screens on fx4800 with recent drivers
This sounds exactly like an issue I am having.
I have the following configuration:
Dell R5400 workstation, with Quadro FX4800 GPU. Planar stereo monitor SD2620W. The DVI output is connected to the first screen, and the right hand display port is connected through a Dell supplied display port to DVI adapter, through a planar hardware based flip mirror card in the R5400, to the second monitor DVI input.
I can get both screens to appear in the nvidia tool at the required resolution (1920x1400) but frequently do not get the second screen after reboot / repower. Restarting x sometimes clears the issue but often does not.
I have used various drivers and still see the issue. I am using the latest driver currently - NVIDIA-Linux-x86_64-256.35.run.
I don't see a hot plug / video input control option on the planar monitor as mentioned in the previous post.
I have looked up Hosiden adapters, but have not found a supplier - could you recommend a part number / distributor?
Attached are the log files off my machine if they are of help.
