Based on the discussion from the comments, seems that the issue is
related to xorg-edgers ppa packages, so this is not System Monitor
related, thus I am closing this bug as Invalid.

I had nvidia and xorg related packages from the xorg-edgers ppa too. Purging
the ppa resolved this bug for me too.
Thanks for the heads up.

Packages from the xorg-edgers PPA also made Gnome Shell crash on my computer
when switching from Windows to Applications tab.
I also noticed increased memory usage on my computer. In normal circumstances
31% of my system memory (out of 2GB) would be used after an X server reset
Nice find!
Xorg-edgers ppa is installed on my latpop. Mark Blakeney reported that
it affects his Nvidia system but not Intel. My laptop uses the Optimus
technology where the Intel HD 3000 chip is the main display hardware and
the Nvidia chip is dormant for the most part unless you use bumblebee.
After doing some testing on my system, I realized that this problem
occurs if you have xorg-edgers PPA activated. Purging the PPA solves the
problem. This is the list of packages that the xorg-edgers PPA upgrades:
intel-gpu-tools (1.0.2+git20100324-0ubuntu1) to
I am running Oneiric x32 with nvidia driver and also get this problem
when I enable xorg-edgers ppa. Purging that ppa removes the problem.
Does not happen on my intel video laptop with same ppa enabled so seems
xorg-edgers + nvidia (290.06) related?
System monitor lock up is repeatable but other
Not sure if helpful but further to my above comment I find that gnome-
system-monitor locks up in a futex() call:
stat64(/proc/2426, {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
stat64(/proc/2427, {st_mode=S_IFDIR|0555, st_size=0, ...}) = 0
stat64(/proc/2500, {st_mode=S_IFDIR|0555, st_size=0,
I am having the same problem with gnome-system-monitor 3.2.1-0ubuntu1 on
Oneiric with a 3.0.0-12-generic kernel.
Here is a trace file.
