Hello out there, some news about this: 1. __Tried nvidia driver from nvidia download:__ Yesterday I gave the subject another try uninstalled all nvidia-current/settings, downloaded the original nvidia 280.13 driver from the nvidia download page, compiled an installed it. The tool creates automatically an nvidia aware xorg.conf.
__Result:__ Same problems as described above. 2. __ Installed again 280.13/oneiric and Gnome Shell / Unity 2(!) D: __ It turns out after some hours/days of real work, that using these environments work flawlessly with the driver. Hopefully I don't suffer from a hardware problem. But this point indicates, that this it not the fact. __Conclusion:__ A. Switching back to Unity 3D there is an interesting issue: just in the moment twinview turns out going to work - with the method described in #6 - compiz (unity?!) crashes. You can have a look for the Xorg.0.log.old (with is the crashed unity session) whats going on there. Xorg.0.log represents the gnome shell session. SO FINALLY: 1. This seams not a bug with nvidia 280.13, this is __definitely a bug with Unity 3D AND nvidia driver__ (doesn't matter which version 275/280/285)! 2. The problem is device indepentend. I am working in different environments (office, at home, at school, doing courses with beamer). The problems are the same, no matter what type of second device i am using (vga/dvi, beamer/lcd). On the fly switching is not working, at least extremely buggy. 3. It turns out, working with an xorg file (constructed with nvidia- settings when you where happy to get a running twinview setting) boots flawlessly into a working environment (Untiy 3D), after logout/login/boot 4. Overall performance degraded (compared with natty / 270series of nvidia) -> I will keep an eye on this issue an probably will file a bug against Unity 3D / nvidia. ** Attachment added: "xorg log under gnome shell" https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/840462/+attachment/2377884/+files/Xorg.0.log -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to nvidia-settings in Ubuntu. https://bugs.launchpad.net/bugs/840462 Title: No Dualscreen-Twinview possible after Upgrade to nvidia-current 280.13 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-settings/+bug/840462/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
