DKMS make.log for nvidia-current-304.43 for kernel 3.7.0-030700rc1-generic (x86_64) Mon Oct 22 19:43:48 CEST 2012 If you are using a Linux 2.4 kernel, please make sure you either have configured kernel sources matching your kernel or the correct set of kernel headers installed on your system. If you are using a Linux 2.6 kernel, please make sure you have configured kernel sources matching your kernel installed on your system. If you specified a separate output directory using either the "KBUILD_OUTPUT" or the "O" KBUILD parameter, make sure to specify this directory with the SYSOUT environment variable or with the equivalent nvidia-installer command line option. Depending on where and how the kernel sources (or the kernel headers) were installed, you may need to specify their location with the SYSSRC environment variable or the equivalent nvidia-installer command line option. *** Unable to determine the target kernel version. *** make: *** [select_makefile] Error 1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1069551 Title: shutdown command does not power off the machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1069551/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
