It seems to be something in the packaging that introduce this problem. The same version from nvidia works just fine.
I just removed nvidia-glx-new, nvidia-kernel-common and dependencies (incl all accumulated restricted-modules), then booted single-user and compiled and installed the original 169.12 driver and resumed normal boot. xorg.conf has not been touched, but 3D-shadows are now normal. (it doesn't fix the dual-head delay though). -- Decoration Plugin: Window shadow color is not displayed as set in plugin properties on NV GeForce 8600 GTS, using nvidia-new drivers https://bugs.launchpad.net/bugs/216999 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
