Java CPU usage directly after boot

I noticed this because I was testing my clones on an external hard drive and noticed from the noise and light a continual usage directly after boot.
The only app that I "think" was running was my CrashPlan backup app.
In Activity Monitor it showed high usage by Java, ranging from 16 to over 50% of CPU.
What would cause this?
Thanks for any education on this issue.

Well, CrashPlan is based on Java. Ergo...

Measure Java CPU usage

Hi,
I'm not sure whether this is the right forum to post this message.
I have a java application and basically it takes lots of CPU time and memory. What my concern right now is the CPU usage. Basically I reduced the number of CPUs from 8 to 4 (Solaris v1280 box) and the CPU usage got increased from 30% to 90% :(
My requirement: Is there anyway that I can measure the CPU usage using Java code itself, so that I can insert those "set of APIs" (for measuring CPU usage), between APIs to collect the CPU usage data?
Thanks,
Siva

The comparison would be unfair (by your definition of unfair) in Java, too, since the JVMs for both platforms are different.
If you are dealing with time, though, 500 milliseconds is 500 milliseconds, no matter what language you write it on or what platform you run it on. If you use VC++ for the Windows stuff, make sure you disable Microsoft extensions so you have some ANSI standard code that will compile with gcc.
Since you are trying to compare operating systems, make sure both machines are using the same processors (and motherboards with the same PCI bus architecture), too. And have the same amount of memory, which is the same speed and architecture on both. Their hard drives should be roughly the same speed, too. The PCI bus usage could vary with network cards, so having the same network cards will be a plus. What it seems to come down to is that you are going to end up measuring the performance of the socket library implementations on both machines.
As far as JNI goes, all it is is a way to write native code and use it in your Java application. I don't know much about it, search around for some examples. There's a tutorial, somewhere, too. Some dude on here, tpritchet, seems to know a lot about it.

Finder High CPU Usage 108% after 5 mins of use

So this is my issue, something odd is happening, I am trying to see where all the work is happening or if it is a bug. No other software seams to hog any significant space, and I am using Photoshop.
I've done a sample of the process as I hope someone can understand it and tell me where the issue is?
Here is the inspect too
https://dl.dropboxusercontent.com/u/82899493/screenShots/Inspect.txt
I've tried disabling the creation of the .DS_store files that had no effect.
also turned of the icon preview in Finder > View > Options but still nothing,
All I can do is relaunch finder and carry on, which is not the best option.
Many Thanks
Matt

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below on this page to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
{ launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef
Step 4
ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of login items' | open -ef
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

Satellite R830-1GZ - CPU usage high ( 25%) and fan speed increase after wakeup

Hello all
The CPU usage of my laptop shoots up to 25% (and beyond) and the fan speed increases dramatically after waking up, but only when I'm using an external mouse (Microsoft Natural Wireless Laser Mouse 6000) - disconnecting the mouse once this has happened does not solve the problem, so I'm always forced to restart my computer if I have let it go to sleep with the mouse connected.
I've noticed that when this happens System Interrupts - Deferred Procedure Calls and Interrupt Service Routines appears in the Resource monitor>CPU>Processes, and seems to explain the increase in CPU usage.
Any ideas on how to fix this would be most appreciated.
I'm using a Toshiba Satellite R830-1GZ with Windows 7 (64 bit). This problem does not happen when I use the same mouse with another laptop (Dell with Windows XP).
Thank you very much.
CM

Thank you for your reply.
I was using the mouse without installing the software that came with it (IntelliPoint), which seems to have been necessary to obtain the latest driver. So I've installed the latest driver now, but... I've still come across the same high CPU usage problem after wakeup.
If your suspicion is correct, should disconnecting the mouse before putting the computer to sleep (hopefully allowing the process that controls the mouse to close properly) stop this problem from occurring when it wakes up?
Could this problem also occur due to an external keyboard? I'm pretty sure it's the mouse (given my experience of using only the external mouse and only the external keyboard) and my understanding is that keyboards don't require special drivers (at least the A4Tech one I have claims it doesn't)... just trying to exclude all possibilities.
Thanks again for your help.

IMac suddenly slow after boot-up

Hello!
I've had my iMac for about two years now (mid 2011 model), never formatted it, re-installed or anything.
Since about a month, all of a sudden, I've had issues with it, being pretty slow to boot. At first it takes about 30-40 seconds for it to actually boot, which isn't horrible but yet slower than it has been. Nothing strange of course. But then when it is actually booted up, everything runs real slow. Loading up Safari can take about 2-4 minutes depending on my mood (when I'm easily annoyed it usually takes longer time). Getting the mail to sync takes ages. And well, launching just about anything takes a fair amount of time longer than it has before. This eases away with the first 10-15 minutes of usage and goes back to normal by then.
Looking through the processes and stuff I'm usually running on about 90-98% unallocated processing power. About 9 GB free ram (out of 12 totally).
I'm running Mac on my job as well, where we use Mac Pros which are about 5 years old, we've never re-installed them or anything, they boot pretty slow, but they doesn't have this slow "directly after boot-up"-feeling as my iMac does.
To a friend using Windows, I'd suggest this as a non-hardware issue. Since Windows usually does that. But I've never had such sever problems on any mac.
I'm using Lion (10.7.5) and are planning to get Maverick when it's released, but I sort of want to resolve this first. If it doesn't mean I should actually re-install and start from scratch, which means I could wait for Mavericks before bothering.
Suggestions?

Checked to see how much space is available ??
Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space.Click your Apple menu  top left in your screen. From the drop down menu click About This Mac > More Info > Storage
Make sure there's at least 15% free disk space. Less can slow your Mac down.
Checked the startup disk lately? You should do this before upgrading the system regardless.
Launch Disk Utility located in HD > Applications > Utilities
Select the startup disk on the left then select the First Aid tab.
Click: Verify Disk (not Verify Disk Permissions)
If the disk needs repairing, restart your Mac while holding down the Command + R keys. From there you can access the built in utilities in OS X Recovery to repair the startup disk.
FYI: OS X Recovery requires a high speed broadband connection.
Backup all your important files before repairing or restoring OS X just in case.

High cpu usage and game lag problem

i have a hp 15 d103 tx
windows 8.1 64 bit
inel i5 4200m 2.5ghz
anti virus installed avast fee antivirus
im using nvidia 820m geforce 344.75 version driver
ram installed 8gb
im experiencing huge amount lag in games and software (autocad)
whenever i run a game (for eg batman origins) it run smooth till 2 or 3 minutes after it lag horrribly
for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
i have to press alt + tab to check task manger it show cpu usage 30%
after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
i dont what the problem high cpu uasge
system idle process sometime shows around 82%
with 8gb of ram still expericing lag
this problem is with all game that i have played and software like photoshop and auto cad
my cousin own hp 15 r007tx and having same gpu nvidia 820m game runs for on his laptop without a lag
is it window 8 problem or something else??

wow finally got the solution by updating bios
just updated the bios from 2.7 to 2.8
no lag now
i guess different cpu load gpu switching on off was problem
but now everything is running good

Simple Java 3D programs CPU Usage spikes to up to 90 percent!

Hi, everyone. Im completely new to Java 3D and Im toying around with basic program structure right now. My code is based off of that in the first chapter on 3D in Killer Game Programming in Java. I removed most of the scene elements, replacing them with a simple grid, Maya style. (Yes, Im starting off small, but my ambitions are grand I intend on creating a polygonal modeling and animation toolset. After all, the Maya PLE is dead damn you, Autodesk! and I just plain dislike Blender.) I implement a simple OrbitBehavior as a means for the user to navigate the scene. That part was basically copy and paste from Andrew Davisons code. The mystery, then, is why the programs framerate drops below 1 FPS and its CPU Usage spikes to up to 90 percent, according to the Task Manager, when I tumble the scene. Id appreciate anyone taking the time to look at the code and trying to identify the problem area. (Ive undoubtedly missed something totally newbish. -.-) Thank you!
(Also, I had the worst possible time wrestling with the posting process. Is anyone else having trouble editing their posts before submitting them?)

Huh. A simple call to View.setMinimumFrameCycleTime() fixed the problem. How odd that there effectively is no default maximum framerate. Of course simple programs like these, rendered as many times as possible every second, are going to consume all possible CPU usage...

but now, when i use rekonq (also tested arora; same issue), cpu usage for the browser shoots up to nearly 50% and stays there. also, pages don't load unless i move my mouse around. flash is worse as well.
(note: after my upgrade, i got a black screen on booting up. i had to use the 'nomodeset' option to disable kms. this probably isn't related, but i thought it might be worth mentioning.)
any ideas?

you're right. i forgot that i made some changes to my igoogle page. the chat function is the culprit. adding it causes the spike. i've reported the problem. thanks for the help!

Cpu usage in java program

i have writen a java program and run on unix, the program will create a connection object which connects to a db, and create a scoket to communicate with another machine.
However, when i use the "top" command in unix and check cpu usage, it used about 35% at the begining, and after few seconds, it drops around 7-8%. May I ask if this is normal? any tips on writing java program which can save more system resources?
please advice. Thanks

Hello friend ,
I am Narayanan from PSNA ENGG College, Dindigul , TN ... I try to find CPU Usage in java and get success.... I am also try form same VC++ file... Try this following steps
if u wont get mail me::: [email protected]
Bye
Steps:
1. Create java file with name CPUUti.java
          class CPUUti {
          public native void displayCPUUsage();
          static {
          System.loadLibrary("hello");
          public static void main(String[] args) {
          new CPUUti().displayCPUUsage();
2.compile the program
               javac CPUUti.java
               Result: Get Class file
3.Create header file
               javah CPUUti
               Result: Header file CPUUti.h is created
4.Open the VC++ with Design wizard
          choose Win32 Dynamic Link Libarary
          Give Projectname, location
5.copy the source file and Header files which you want
Source files:
               CpuUsage.cpp
               Main.cpp
               StdAfx.cpp
Header Files:
               CpuUsage.h
               PerfCounters.h
               StdAfx.h
6. include the Header file CPUUti.h in header file
7. create new C++ source file getCPU.cpp in the same project
8.include getCPU.cpp file to the Sourcefile list in the same project
9.copy this code in to getCPU.cpp
               #include "CpuUsage.h"
               #include "CPUUti.h"
               #include "PerfCounters.h"
               #include "StdAfx.h"
               JNIEXPORT jint JNICALL Java_CPUUti_Display
               (JNIEnv * s, jobject s1)
                    CCpuUsage usageA;
                    CCpuUsage usageB;
                    while (true)
                         // Display the system-wide cpu usage and the "Explorer" cpu usage
                         int SystemWideCpuUsage = usageA.GetCpuUsage();
                         int ProcessCpuUsage = usageB.GetCpuUsage("explorer");
                         printf("System-wide Cpu Usage: %3d%%, Explorer cpu usage: %3d%%\r",SystemWideCpuUsage, ProcessCpuUsage);
                         Sleep(1000);
                    return 0;
10. copy the headerfiles which is present in the jdk\include and jdk\include\win 32
paste to the VC++\include\
11.Build the VC++ file.
12.DLL file is created inside the Debug\ folder
13.copy that DLL file and paste it to the java source file location
Run the java file and enjoy...................

Excesive CPU usage - java process OBI related

Hola a todos,
We have installed OBIEE 11.1.1.5 in a virtual machine (a clean one, just DB and OBI) and since a few weeks we've noticed perfomance issues. There is a java.exe process running with 30 - 50% CPU usage and if we stop it, OBIEE stops working as well, so we think it may be related, but we dont have any further clues.
Has anybody dealt with something liket his before or does anyone know if there's a log where we could check this?
Thanks in advance.

Tuning
Whether its a 64 bit or 32 bit of SUN or Jrocket ,
Please increase the heap size parameters to Xms & Xmx to atleast2048 (min and max to atleast) 2GB
Below were the comments from Oracle Support
Best Practices Guide for Tuning Oracle® Business Intelligence Enterprise Edition
In JRockit JVM (R28), the heap grows faster than before. The JVM also ensures that the heap size grows up to the maximum Java heap size (-Xmx) before an OutOfMemory error is thrown. In addition, the default value of the -Xmx option is changed from 1 GB to 3 GB on 64-bit OS. Note the JRockit JVM auto shrinks the heap if it is unused or if other applications require more physical memory.
Note: It is recommended to use the default garbage collection mode i.e. -Xgc:throughput. Also
large heap reduces the garbage collection frequency and fragmentation, improving the throughput
of the application; however, a large heap increases the memory footprint of the Java process.
*Warning: Make sure you have enough physical memory allocated / available on 64bit servers and then use the above settings as a starting point, and after load testing, adjust as needed. For a stable / an even performance over time, you should set the initial heap size (- Xms) to the same value as the maximum heap size (-Xmx).
Common JRockit JVM issues seen with BI (i.e. bi_server1) managed
servers:
Startup Times Take Longer When Using JRockit JVM Versus Sun JVM: The Oracle® JRockit JVM is by default optimized for server use, which means that the startup times can be longer in favor of high performance as soon as the application is up and running. Moreover, as the application runs, the JRockit JVM optimizes frequently called methods, improving the performance further.
When you run the JRockit JVM on a 64-bit system with a heap size less than 4 GB, if native OutOfMemory errors occurs despite memory being available only then add the parameter -XXcompressedRefs:size=32GB in JVM startup options to enable heap to grow up to 32 GB heap (practical limit of 25 GB). This will fix the issue native OutOfMemory errors. Moreover heap size still be restricted till the limits defined using -Xmx only benefit would be your heap will get the capability to grow beyond 4 GB up to 25 GB due to increase in size of pointer to
32 bit address.
On Oracle Solaris SPARC, due to the way classblock memory is reserved,Oracle® JRockit (R28) might occasionally run out of memory when a large number of classes are loaded (in the order of 100000).Workaround: The default value of -XX:MaxClassBlockMemory=50 MB, and a reasonable value is around 75 MB.
By design Oracle® JRockit will often use more memory than Sun JVM because JRockit compiles everything and is optimized for being a server-side JVM. So if
your customer have limited resources (i.e. CPU, memory) then it is recommended to experiment with switching to the Sun JVM which should save some system resources, but customer really should consider to do a performance tuning and sizing exercise, and determine if they have sufficient memory / CPU’s to support their requirements.
It is important to keep Oracle® JRockit R28.1.x up to date with latest fix release because the latest release provide fixes for security vulnerabilities, performance,
and other improvements of the Oracle® JRockit R28.1.x
Tuning 64bit Sun JVM
suggested
Minimum heap -Xms2048m Maximum heap -Xmx2048m
Minimum permanent generation heap -XX:PermSize=512m Maximum permanent generation heap -XX:MaxPermSize=512m
I'm not sure from where I've copied but save the same in text file.

High CPU usage while running a java program

Hi All,
Need some input regarding one issue I am facing.
I have written a simple JAVA program that lists down all the files and directories under one root directory and then copies/replicates them to another location. I am using java.nio package for copying the files. When I am running the program, everything is working fine. But the process is eating up all the memories and the CPU usage is reaching upto 95-100%. So the whole system is getting slowed down.
Is there any way I can control the CPU usage? I want this program to run silently without affecting the system or its performance.

Hi,
Below is the code snippets I am using,
For listing down files/directories:
        static void Process(File aFile, File aFile2) {
          spc_count++;
          String spcs = "";
          for (int i = 0; i < spc_count; i++)
          spcs += "-";
          if(aFile.isFile()) {
               System.out.println(spcs + "[FILE] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newFile = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nf = new File(newFile);
               try {
                    FileCopy.copyFile(aFile ,nf);
               } catch (IOException ex) {
                    Logger.getLogger(ContentList.class.getName()).log(Level.SEVERE, null, ex);
          } else if (aFile.isDirectory()) {
               //System.out.println(spcs + "[DIR] " + aFile2.toURI().relativize(aFile.toURI()).getPath());
               String newDir = dest + aFile2.toURI().relativize(aFile.toURI()).getPath();
               File nd = new File(newDir);
               nd.mkdir();
               File[] listOfFiles = aFile.listFiles();
               if(listOfFiles!=null) {
                    for (int i = 0; i < listOfFiles.length; i++)
                         Process(listOfFiles, aFile2);
               } else {
                    System.out.println(spcs + " [ACCESS DENIED]");
          spc_count--;
for copying files/directories:public static void copyFile(File in, File out)
throws IOException {
FileChannel inChannel = new
FileInputStream(in).getChannel();
FileChannel outChannel = new
FileOutputStream(out).getChannel();
try {
inChannel.transferTo(0, inChannel.size(),
outChannel);
catch (IOException e) {
throw e;
finally {
if (inChannel != null) inChannel.close();
if (outChannel != null) outChannel.close();
Please let me know if any better approach is there. But as I already said, currently it's eating up the whole memory.
Thanks in advance.

Config Manager Agent - after Hardware Inventory High CPU Usage with WMIPRSVE and very fast empty Battery

Hi there,
since a few days there is on some machines (40-60) a high cpu usage on one core (quad core cpu machines) with the WMIPRSVE.EXE if the HARDWARE INVENTORY CYCLE started.
i try out some tests, read some forum articles and troubleshooting the WMI management but a real problem i doesn´t see.
in some articles i read that hardware inventory runs about minutes up to more hours but some machines runs longer, someone more as 1 day.
here an example of mine PC:
at 8:07 i started Hardware Inventory Cycle, in the InventoryAgent.log i can see that some Collection Namespace are captured.
after a few minutes there stopped and does nothing round about 5.9 hours or better, after 21436.097 Seconds.
For any hints i am grateful. :)

Looks like something in one or both of those wmi queries. it goes from 8:10:03 to 14:06:43 right around there. 6 hours to do that...
try running those queries from wbemtest manually; and see which one just never finishes.
Standardize. Simplify. Automate.

After updating to latest Firefox - when I click on google taskbar my CPU usage goes to 100% and stays there... and computer is really slow. No other search engine show the 100% usage like Google. There was NOT a problem with older versions of Firefox...?

My computer got really slow after updating to latest version of Firefox. I checked all processes and I was testing the system. THe CPU usage goes between 2 and 70 percent staying around 25% on average, when I check my e-mail. As soon as I click on Google taskbar (without even typing in anything) the CPU usage jumps to 100% and STAYS at 100 %, and computer extremely slow.

High cpu usage after a while

Sometimes, after a while, firefox (36.0.4) uses up 1 core of my CPU (is a quad core due to hypertreading). The way it happens is really strange. Many tabs without a problem until suddenly ff decides to floor it. This is alway in the run, not on startup or close. All add-ons need to ask my permissions to be activated, this includes flash.
On close, I ordered ff to clear all history and cookies.
Notes that could be important (The behavior encountered while using it. This varies from time to time):
opening new tabs (a lot or a few) => "heavy" load during site loading, then idling
==> The above makes sense
- same as above but load continues to be heavy. => could be some badly written javascript on the site, however, sometimes this occurs with sites I know have no stressful javascript
==> The above seems odd
- Browser is idle in the background (not actively using it). Then all of the sudden "lets floor it until closed".
==> The above seems pretty odd
- When confronted with high CPU usage, closing ff doesn't close it (the ff process remains active. Not a ff process, THE ff process). => High CPU usage remains
==> The above looks like that there is definitely something wrong here
This last one has some other things to keep in mind
- When it happens and I close ff, upon restarting it it will ALWAYS ask to close ff. After confirming to close it, it will start and behave normally.
- When killing ff via the task-manager, or other means like powershell commands, restarting it will result in an idle ff even after every tab is loaded again.
I hope this isn't a heisenbug and there is a solution to this, a reboot ff button would be a nice workaround though. I personally think that it must be some routine in the code that decides to go nuts for no reason.
If you need further details, feel free to ask.
Thanks in advance

Tried those before and tried them again. Unfortunately, the problem keeps repeating itself at random times. As said, sometimes it doesn't occur and sometimes suddenly it does. Keep the following things in mind about this, what seems like a heisenbug, behavior.

As stated, a reboot ff button would be a nice workaround. I personally think that something like a tread must get stuck in some sort of infinite loop. Browsing in ff works just fine though. I just don't like the fact that I turns into a "gasoline guzzler".
Again, thanks in advance

High CPU usage after closing a program.

Okay, this is annoying. Doesn't happen on all programs, but too many.
When I close an application, in normal way, alt+f4/press x/file->quit the program quits, BUT, "ghost" application starts, which raises to 100% CPU usage. Then I have to close it via sigterm/sigkill. This has happened (atleast) with mplayer, nvidia-settings (which doesn't even start, but cpu usage raises to 100% anyway, and ghost application starts) and WoW thru Wine. Now, I have absolutely no idea what is going on, and I've found nothing on google.
I think it became after I upgraded to 2.6.29 kernel, it's 2.6.30 now and still the same.
A little help please

The nvidia-settings starts, as it shows on system monitor (htop, etc) but I am not getting the window, and cpu usage raises to 100% instantly. Terminal output:
dfizzle@ohai ~$ nvidia-settings
