Hi all,

I'm altering my setup and using a Nvidia drive in the latest x-org release.

I am trying to use Twinview.

I have read an interesting line from the Nvidia Readme

DPMS and TwinView
DPMS modes "suspend" and "standby" do not work correctly on a
second CRT when using TwinView -- the screen is just blanked,
rather than putting the monitor into the requested DPMS state.
- DPMS and Flat Panel
DPMS modes "suspend" and "standby" do not work correctly on a
flat panel display -- the screen is just blanked,
rather than putting the flat panel into the requested DPMS state.


which is very similar to a problem I'm having

In my monitor section I disable DPMS to be on the safe side

Section "Monitor"
Identifier "Monitor0"
VendorName "DELL"
ModelName "DELL 1901FP"
HorizSync 30 - 80
VertRefresh 56 - 76
Option "DPMS" "0"


In the devices section there is NO option to disable DPMS so the only option is to hope that the monitor definiation is applied to both monitors in Twin view.

However on startup, I get similar symptoms as mentioned in the Nvidia Readme, and in the log I see

(**) Option "dpms"
(**) NVIDIA(0): DPMS enabled

so even though I've disabled it, it still enables it.

More reading on Nvidia docs suggest that the Nvidia driver may choose to ignore options. I find it hard to believe that Nvidia after releasing info on a bug and how to fix it (disable DPMS) would allow the Nvidia Xserver to then ignore the option that fixes the problem.


Anyone else had anything to do with this, or read anything, or even got any comments ?
