A week or two ago, Software Updater started offering me version 304.134-0ubuntu0.16.10.1
It had never offered me the "fixed" version 304.132-0ubuntu2, but only the original version 304.132-0ubuntu1, which did not load into the kernel (with the mtrr_add and mtrr_del errors). I tried the 304.134-0ubuntu0.16.10.1 version offered, and it fails just like 304.132-0ubuntu1. Somehow, the fix never made it into my distribution repositories, and was not incorporated into the new 304.134-0ubuntu0.16.10.1 version. I still am forced to use an older version ( 304.131-0ubuntu5 ) in order to have an nvidia driver that both loads into the kernel, and allows Hugin to run correctly... ------------------------------------------------------------ scott@scott-ASUS-M2N68-AM-PLUS:~$ uname -a Linux scott-ASUS-M2N68-AM-PLUS 4.8.0-37-generic #39-Ubuntu SMP Thu Jan 26 02:27:07 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux scott@scott-ASUS-M2N68-AM-PLUS:~$ lsb_release -dsc Ubuntu 16.10 yakkety scott@scott-ASUS-M2N68-AM-PLUS:~$ echo $DESKTOP_SESSION Lubuntu -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nvidia-graphics-drivers-304 in Ubuntu. https://bugs.launchpad.net/bugs/1634802 Title: Could not insert module Status in nvidia-graphics-drivers-304 package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-304 source package in Yakkety: Triaged Bug description: Ubuntu release: 16.10 Yakkety Yak Kernel version: 4.8.0-22-generic x86_64 Package version: 304.132-0ubuntu1 The nvidia module cannot be loaded.
