I manage 300+ machines that run openafs that has a dkms built kernel
module like the nvidia module that needs to be built. I also manage
dozens of nvidia gpu servers where users have sudo access and can
install anything they want. Here is a snippet of what I found. Note this
is for 16.04 systems
I did an online chat with Dell to see if they new anything about this
and they could not help. Here was there response:
Ok. Well, I had them review the article and they see many vendors
having the same issue. We don't have any updates / patches for the
Matrox graphics card for this kind of issue.
Still the same issue on 2 new Dell T630 servers Ubuntu 14.04 LTS.

I am seeing this in precise 12.04, latest patches, some machines have
the issue, others do not:

% df -hl
df: `/var/lib/lightdm/.gvfs': Permission denied

If someone is logged into the desktop, gvfs mounts in there home dir,
and df works if you ssh login as another user and do a df. The problem I
am seeing is when no one is logged in and /var/lib/lightdm/.gvfs is
mounted. For example:
No one logged into the desktop:
$ df
df:
Another observation. When no one is logged in and /var/lib/lightdm is
mounted the directory permissions do not allow other access:
% ls -ld /var/lib/lightdm
drwxr-x--- 9 lightdm lightdm 4096 May 6 09:50 /var/lib/lightdm
If someone is logged into the desktop gui the gvfs directory permissions
6 matches
