           Summary: incorrect memory value displayed for "mem"
        QA Contact: goodies-dev at xfce.org
          Severity: normal
    Classification: Panel Plugins
                OS: Linux
          Reporter: pauljohn at ku.edu
          Hardware: Other
            Status: NEW
           Version: 1.0.0
         Component: General
           Product: Xfce4-systemload-plugin

Debian Wheezy, xfce4-systemload-plugin 1.1.1-1+b1, on a Dell Precision M4600
with 8GB RAM.

The "mem" value reported by systemload is consistently wrong. The applet shows
a green bar with a very low value. Hovering mouse over that I see:

"1596MB of 7962MB used"

At the same time, the output from "free"

$ free -m
             total       used       free     shared    buffers     cached
Mem:          7962       7763        198          0        521       5557
-/+ buffers/cache:       1684       6277
Swap:         7627          0       7627

Do you see same? If so, how can I help.

Do you require other info on my system to understand the problem?  Could I just
guess a few things?  Here's some paste.
