VIDIA has its own implementation of dualhead support called twinview enabled by default when using nvidia driver. Xorg (and GNOME) reports (availible) refresh rates wrong, and you cant select the good ones. This is absolutely annoying when using CRT monitors.
Using the following option in display section solves the problem (by switching off twinview): Option "DynamicTwinView" "False" Then the resolutions reports correctly, and can be selected correctly. Since Gutsy have a displayconfig-gtk app, with dual monitor support, (and nvidia-settings is hidden in the menu by default) the above line should be add to the Xorg.conf by default when using nvidia binary drivers. -- [nvidia-glx] unable to "set" proper screen refresh rate due to DynamicTwinView https://bugs.launchpad.net/bugs/92599 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
