Robert, This is a sample of my /var/log/kern.log messages regarding xfce4 -netload-plugin attempts to read network traffic:
Apr 9 14:46:34 localhost kernel: [ 786.952187] audit: type=1400 audit(1428601594.953:805): apparmor="DENIED" operation="open" profile="/usr/lib/lightdm/lightdm-guest-session" name="/proc/23556/net/dev" pid=23556 comm="panel-2-netload" requested_mask="r" denied_mask="r" fsuid=129 ouid=0 In the example above, PID 23556 belongs to command "/usr/lib/x86_64 -linux-gnu/xfce4/panel/wrapper-1.0 /usr/lib/x86_64-linux- gnu/xfce4/panel/plugins/libnetload.so (...)" In my experiments with apparmor profile for lightdm-guest-session, I've found that just granting read access to /proc/[0-9]*/net/dev is enough. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1442609 Title: Guest session can't read "/proc/net/dev" and/or "/proc/*/net/dev" Status in Light Display Manager: Triaged Status in lightdm package in Ubuntu: Triaged Bug description: I'm customizing my guest sessions in Xubuntu 15.04 and discovered that xfce4-netload-plugin can't show current net traffic. After investigating netload plugin source code, I've found that a possible reason for this strange behaviour is that guest sessions are unable to read /proc/net/dev and/or /proc/<PID>/net/dev. Could you please review current apparmor profile for lightdm-guest- session so it can get read access to /proc/net/dev?
