Hi.

On my Sony VAIO laptop i had to manually specify display output and so fourth in /etc/X11/xorg.conf. I had to extract the EDID information in Windows before i could get a usable configuration in X.

This is how i did to get it to work(there might be an easier way):

Quote:
The Workaround

The EDID information is detected fine in windows, so we can extract it from there. We then edit xorg.conf to tell the driver that a display is connected to DFP-0 (the internal port) and to use the EDID we extracted instead of probing the monitor for it.

Please note: I am just a user and take no responsibility for any problems that may occur as a result of this workaround. Make sure you understand the purpose of each step and proceed at your own risk.

1. Extract the EDID file from within windows. I used the program softMCCS which can be found here. Open the program and go to file -> Save EDID as. The filename you choose doesn't matter, but make sure to use the binary (bin) format. Put this on a memory stick or use some other method to copy it to your linux filesystem.

2. Boot into linux, without X and put the EDID file in your /etx/X11 folder (it could actually go anywhere, but I found this to be convenient).
Code:

sudo cp /path/to/your/edid.bin /etc/X11/

3. Backup your current xorg.conf file.
Code:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

4. Edit /etc/X11/xorg.conf and replace the Device section with this
Code:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "ConnectedMonitor" "DFP-0"
Option "CustomEDID" "DFP-0:/etc/X11/youredid.bin"
EndSection

In some cases you might not have a correct Monitor section either and depending on your maximum screen resolution it could look something like below. to get a most probably working Modeline go here.

Section "Monitor"
Identifier "Monitor0"
VendorName "Sony"
ModelName "X-Black LED"
Option "DPMS"
Modeline "1366x768" 60.000 1366 1388 1410 1430 768 776 784 840 +hsync -vsync
EndSection

Replace "youredid.bin" with whatever you named your EDID file. The two Option lines are what does the trick. The first tells the driver you have a display connected on the internal DFP-0 port. The second tells it not to probe for an EDID, but rather to use the one you are providing.

5. Restart X and you should see the NVIDIA logo flashing right at you, and after a few seconds you should be presented with a working X.

Don't know about cuda, haven't tried it at all.

The white-gray-black strip could indicate a incorrect resolution setting in your boot configuration setting.

Have you tried to add/change screen options in the nVidia screen tool?

I think you manually need to add your screen options since we manually added one of them to the xorg.conf, not sure tho, haven't played around with it yet, since i cannot use it really much due to the backlight issue I'm currently having.
