Follow up to my above comment: Disabling the local cdrom repository in my Synaptic settings seems to have worked around this problem.
To summarize: -- go to System->Administration->Synaptic Package Manager->Settings->Repositories and uncheck the "cdrom with Ubuntu 9.04 'Jaunty Jackalope' checkbox. -- killed 'cdrom' process that was hung above -- Run System->Preferences->Appearance->Visual Effects to use "Extra" and trigger the driver search. Waited for a few minutes; saw some activity in 'top' -- rebooted after it was done After reboot, nVidia driver works, and I can change my Appearance -> Visual Effects settings. I did notice my wireless connection (wlan0; Intel PRO/Wireless 5300 AGN [Shiloh] using 'iwlagn' driver ) had trouble right after I did this, and I had to disable and re-enable it in Network Manager before it finally reconnected. Not sure if this is related, but that's what I observed. -- 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
