I had the same problem and I noticed that the nvidia module could not be loaded when doing:
modprobe nvidia However, after reinstalling the drivers, they could be loaded again: apt-get install --reinstall linux-restricted-modules-2.6.22-14-generic modprobe nvidia The problem is that this "volatile/nvidia.ko" file is deleted after every reboot and the module needs to be reinstalled. So I looked inside the linux-restricted-modules-2.6.22-14-generic package (in the postinst script specifically) and found this call: lrm-manager --kver=KERNEL_VERSION Which does create that file and allow the module to be loaded. Therefore, at the moment, my work around is to put the following in /etc/rc.local: lrm-manager --kver=`uname -r` modprobe nvidia /etc/init.d/gdm restart exit 0 -- nvidia.ko: No such file or directory https://bugs.launchpad.net/bugs/148943 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
