Running Ubuntu 12.04.2LTS, GNU/Linux 3.2.0-51-generic x86_64, with NVIDIA GTX 275 board. Today I routinely hit the "install up-dates" button in Update-Manager, without paying much attention to what was being updated (some 78 files). But upon rebooting after the update, the machine came up in text-only mode, no X-graphics.
This has happened to me occasionally in the past, and the remedy has always been to fetch and install a newer NVIDIA driver. I did so, now with the latest NVIDIALinux-x86_64-319.32.run installer. But this time it didn't help.
Running `xinit` gives the error message:
"API mismatch: the NVIDIA kernel module has version 304.88 but this NVIDIA driver component has version 319.32. Please make sure that the kernel module and all NVIDIA driver components have the same version". That sounds like excellent advice -- if only I knew how! The message really flummoxes, since it's been ages since I had that version of NVIDIA installed.
If, on boot-up, I choose the next previous Linux version (3.2.0-49-generic x86_64) I now get the same (non-X-graphic) result. And that's true even when I re-install the previous NVIDIA driver (NVIDIALinux-x86_64-310.40.run) which was working before I updated Ubuntu. At each attempt to install the NVIDIA drivers I get the report "installing DKMS kernel module" -- but apparently not.
In short, I can't even revert to the combination of Linux kernel and NVIDIA driver that was working before I hit the "update"-button.
I guess the most succinct question is: how do I build and install an appropriate NVIDIA kernel module? But any hints on how to get out of this dilemma will be most welcome.
