Xorg using 5-40% of CPU time all the time

After upgrade of kernel to 2.6.27.7-1, the xorg daemon uses 5% of cpu usage doing nothing and up about to 40% on basic usage of firefox. My cpu is a Core2Duo 2.2GHz. I try instaling new versions of xorg and nvidia but the problem persists. Any ideas? My xorg.conf:

I install nvidia-beta from AUR, but this issue still happens.
Some sites which almost freezes Firefox works better now (look this thread: http://bbs.archlinux.org/viewtopic.php?id=50776), but youtube videos crashes Firefox aleatory here.

Firefox is using large amounts of CPU time and disk access, and I need to know how to shut down most of this so I can actually use the browser.

Firefox is a very busy piece of software. It's using large amounts of CPU time and disk access. It puts my usage at low priority, so I have to wait for some time to be able to use my pointer or keyboard. I don't know what it uses all that CPU and disk access time for, but it's of no use to me. It often takes off with massive use of resources when I'm not doing anything, and I may not have use of my pointer for several minutes. How can I shut down most of this so I can use the browser to get my work done. I just want to use the web site access part of the software, and drop all the extra. I don't want Firefox to be able to recover after a crash. I just want to browse with a minimum of interference from Firefox. I would think that this is the most commonly asked question.

When I download firefox, using recommended setting, or my own, all the sub files/folders like plugins, modules, updater end up on the desktop as well as in the file location. And when I try to put them into the file location, they don't. And when I delete them, FireFox won't open. I tried deleting FireFox and reinstalling it multiple times, and a message pops up sometimes that says FireFox may not have installed correctly, so I follow the steps, but all the extra icons on my desktop don't go away. This has happened every time I have downloaded FireFox. The browser itself works, but I need to know how to get rid of these icons, but still be able to use FireFox. This is on a new computer, with Windows 7.

Using lightroom 5.7.1 not all the meta-information is copied when exporting pictures

using lightroom 5.7.1 not all the meta-information is copied when exporting pictures: city and country are not copied, although this information appears if i open the original file in photoshop. if i export this file via lightroom, the information dissappears.
does anyone know how to solve this problem?

thank you!
although i did not change anything updating from lightroom3 to lightroom5, this box was automatically checked in all presets. now i unchecked it and everything works fine.

If you are unable to get the iPod into Disk Mode to try and restore it, it's a very good indication, as mentioned in the article, that the iPod's hard drive is damaged and in need of replacement either by Apple or a third party repair company.

Why Lightroom keeps using 30% CPU power all the time?

Hello all,
I am relatively new to LIghtRoom.
I started working on a new set of photos (400 app.). I opened it as new directory.
Since then, all the time I work on theses pictures Lightroom keeps using app. 30% of CPU time.
The over all time I spent on these photos is estimated to be more then 30 hours (yes, I am slow and open each in Photoshop while Lightroom is still opened). So I guess Lightroom finished all the rendering it wished to do.
My question is why and what it keeps calculating and is there a way to stop it?
System configuration:
Single core Intel Pentium 4 CPU, 3.6 GHz (Hyper Threading allowed)
2 GB RAM
NVidia 6600 based graphics card (256 MB)
Both LightRoom 2.3 and PhotoShop CS4 are opened
Please help - the system is slow anyway. It can realy use those extra CPU power.

The warning badge can be switched off from within View Options panel (Library module View menu) by unchecking the option labelled Unsaved Metadata.
With regard to your question as to whether Lr edits will show in Photoshop and Bridge/ACR - you'll be fine with Photoshop. However, for Lr edits to be visible in Bridge/ACR you will now have to manually save the metadata to each file (i.e. select file(s) then hit Cmd/Ctrl+S to save metadata to file).

(CS4) Photoshop 32Bit + Bridge + Win7 = CPU 100% all the time

This is something that occurred to me many times now:
I need to use the 32Bit-Version of Photoshop because of all the Plugins I use and some of them run ONLY on one of them at a time, like PixelBender ( W H Y ? ? ? )
So: Whenever I have Photoshop 32bits running (because it would default to 64bits where my plugins are not available) and open Bridge afterwards to open a file in PS, Photoshop stays at 100% CPU (on one of the cores) all the time without any reason. I also checked if there were selections active (yes, selections sometimes pretty much need a LOT of CPU power, whyever!)
Otherwise, when I first start Bridge and THEN Photoshop 32Bits, the CPU usage is okay. Something seems using up much CPU power in some kind of endless loop / dead lock or something?!
It's quite annoying, because I don't use Bridge that often. Sometimes I want to start Bridge "on demand". And if I have opened Photoshop already I would have to close down everything just to be able to start Bridge again without losing a full CPU core.
So if anyone has the same issues like me: Just reverse the opening order: First open Bridge, THEN open Photoshop and everything should be fine.

I don't have an answer to your question about the infinite loop, but I can answer this:
function(){return A.apply(null,[this].concat($A(arguments)))}

( W H Y ? ? ? )
A plugin is a special kind of callable function library (Dynamic Link Library, or DLL in Windows speak). A 32 bit DLL cannot be used by a 64 bit version of Photoshop. In order to use the completely different instruction set the processor provides for 64 bit operation, the plugin code must be compiled specifically for 64 bit operation.
All plugins developed before the time of Photoshop CS4 were originally developed as 32 bit applications, because Photoshop was only 32 bit. Even today, 32 bit users outnumber 64 bit users by a large margin.
Microsoft makes it almost trivially easy to compile 32 bit source code as a 64 bit application, BUT... If the programmer hasn't been careful in his use of data types - specifically those that will be a different size (e.g., a pointer will be increased from 32 bits to 64 bits), then doing so - even if the software compiles successfully - might yield a non-functional plugin.
Sadly, many programmers are not careful with their use of data types. This is 30+ years of software engineering talking.
With good design and good coding practices, the code will be good and the programmer will be able to compile a 64 bit plugin quickly. Even bad code can be cleaned up in time, so that it can be made to work in 64 bit form.
But there's even more that must be done...
Most serious software uses an installer.
Installing software on a 64 bit system requires big changes to the installation package, or maybe even a whole new installer. There is, for example, the added complexity that you, the user, might want the proper variant of the plugin installed into each of your 32 bit and 64 bit Photoshop installations. And possibly multiples (e.g., CS4, CS5). Creating a good installer package is somewhat akin to designing a rocket booster. Except that the latter is generally agreed to be easier.
And all this is just on the Windows side! It must be repeated for the Mac, assuming the plugin is marketed into that segment as well.
So... If your favorite plugin doesn't run under Photoshop x64, and the author doesn't have an upgrade available that does, maybe they are struggling to make it work, maybe they decided the x64 user market isn't big enough for their attention right now, or maybe they're just working on something else.
Probably more than you wanted to know, eh?

Sockd process uses a lot of CPU time

Hi,
I'm running the Sun Java System Web Proxy Server version 4.02 on a SunFire V210 dual processor box running Solaris 10 with the default socks5.conf for testing.
Just browsing a few web pages in Firefox or IE using the socks proxy boosts CPU usage from the sockd process to a staggering 50% and stay there for several minutes.
Comparing with the old NEC reference Socks5 daemon the Sun version is really performing badly.
The system is pretty standard though I have tuned /etc/system and the tcp stack using recommendations in the proxy administration manual. All Solaris 10 patches are installed.
prstat output:
   PID USERNAME SIZE   RSS STATE PRI NICE      TIME CPU PROCESS/NLWP
24519 proxy    6664K 4384K cpu1     0   10   0:11:18 50% sockd/43Any ideas what's wrong or do I have to stick with the old NEC reference daemon?

MBP Running at 98% CPU Usage All the Time

I'm not sure exactly when this first started, but now whenever I'm in Mac OS X a process called "Socket" running under "root" is constantly using ~98% of my dual-core CPU (out of a possible 200%). This prevents my computer from sleeping and it's obviously using a lot more energy all the time. I can shut the process down and the computer will relax for a while, but it's only a matter of time before it starts again. Any ideas on the matter? The help is greatly appreciated.

The process name is "socket". Is the user cupsd? Check for a print job stuck in the queue.
CUPS stands for Common UNIX Printing System; the cupsd process is the main print engine for OS X.
Run Applications > Utilities > Disk Utility, select your HDD and click Repair Permissions.
You might also try trashing your printing preference files (user/library/preferences folder, .plist files with names that start with com.apple.print).
Hope this helps...
Ps: There's a nice printing repair utility (shareware) out there:

Nipalsm.exe using up 50% of CPU time

Hello Everyone:
I'm having a problem using labview 8.6 on a Dell Dual core E6500 labtop. The computer started acting very sluggish and I've noticed that even when labview is not running, the Nipalsm.exe is using up 50% of the CPU time. I've tried reinstalling labview but it hasn't work. I went back and checked an older computer running labview 7.1 and on that computer nipalsm.exe is using at most 1%.
Best Regards,
Mark

This isn't LV related, but some driver stuff (DAQ, DAQmx, DMM, ....). So try reinstalling those. Maybe you could also get a diffrent version (older ones by supplied CDs, newer ones by download from NI).
If you have any support contract (and that should be if you recently bought that hardware), phone your NI rep, as it might be beyond the scope of the community to solve these issues.
