Problem with Lenovo w520 driving external displays. Ubuntu 11.04
 
I've got a Lenovo w520 attached to a think pad mini doc plus series 3. Ubuntu 11.04 is installed. Latest Nvidia drivers are installed. Optimus is turned off.

I want to get it to drive a Dell 30 inch digital monitor with 2560x1600. At best, the NVidia X Server Settings comes up with Dell having a 1280x800 resolution in twin display. I've tried many different settings of Xorg.conf and several different bios settings. This seems to be a bug/problem with the NVidia drivers.

Can anyone help with this?

I can't help with your problem, but:
I was thinking of getting one of those.
Do you have the Quadro 1000m or 2000m?
Have you tried Cuda or OpenCL or anything that uses OpenGL on it?


Also, it might be good to post your Xorg.conf.

I have this problem without using the docking station, but when i click detect display the external doesn't show up. http://i.imgur.com/EAPQd.png

Not sure how I can 'force' nvidia drivers to detect the external display.

Plz attach report by running nvidia-bug-report.sh as root.

I don't know whether this is the same or a different bug, but I have similar issues with a Lenovo W520, issues that are extensively discussed on the forums. There are workarounds for external VGA monitors but not, as far as I've been able to tell, for external digital monitors.
