Thanks for the kind words and prompt reply. I know how frustrating a lack of information can be (I answer support tickets in launchpad).
Just to clarify, this problem _started_ at the point I installed Ubuntu Feisty 64-bit with the NVidia driver 9631 from the Ubuntu repository. As far as the driver goes, I can easily remove the manually installed driver and go back to nvidia-glx (9631) or nvidia-glx-new (9755) to comply with requirements to get support through launchpad, and will flick back to the manual driver to get support from NVidia if that is required. I can easily switch between the drivers - I have had quite a bit of practice over the years ;) I get _nothing_ on the display _from_ _boot_. No BIOS splash, no memory count, no scan of USB devices - nothing at all. This is all before grub / linux loads. The flat panels indicate there is no signal. I refuse to believe that it is merely hardware failure of _both_ cards at the same time. I am more willing to suspect that the 9631 driver has done "something" to the cards, put them into a funny state. My main gripe is that this was a plain blank install of Ubuntu, all I did is what anyone who has two displays and would like twinview to work would do, install the binary driver from the repository. That's when it all went wrong. I will give the UseDisplayDevice option a try and report back. -- New feisty 64bit install causes nvidia card failure https://bugs.launchpad.net/bugs/110361 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
