I have a GeForce 8600 GT and I have the same problem with same error message.
By default the desktop effect seemed to work when I first compiled the binary drivers, but when I selected "advanced effects" I got an error message "no nvidia card found", so I tried to disable desktop effect but since then I never been able to re-enable it, I always get the no nvidia card message.. As for the restricted drivers manager it worked once on my old pc with my GeForce 7600 (on feisty) but failed to recognize my 8600 (on gutsy). I agree that the initial error message is quite vague as it's obvious that desktop effects have not been enabled, an explanation or a hint on how to resolve this issue would be welcome and more useful. h3 -- When desktop-effects fails it gives no explanation https://bugs.launchpad.net/bugs/92370 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
