I have the same issue on a fresh install of the official 9.04 release. It came about when I tried to activate he NVidia driver via System->Administration->Device Drivers.
And, as with another poster, before installing 9.04, I had Ubuntu 8.10 installed and the nvidia drives were working fine on that release. In general, this release seems to have a lot of trouble with the restricted device drivers: initially after installing 9.04, the Device Drivers screen didn't even show ANY restricted device drivers. Only after a couple hours of trying and then changing Software Sources from "Main Server" to a specific mirror and then doing an update check did the drivers show up :-( -- jockey backend crashed when trying to install nvidia driver https://bugs.launchpad.net/bugs/350776 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
