http://ubuntuforums.org – Hi !! I have system with Pentium D dual core processor. Recently my conky & system monitor showing that only one processor core is working instead of two. Is this normal software problem or wrong Bios setting ? or my second core processor is not working? Is it possible for system with dual processor to work even if one of two processor get damaged? Recently I have changed my old 80 GB hdd with 500GB. Since it never get detected in first boot I have changed some of BIOS settings but till it doesn't get detected in first boot. I have restart twice to boot on hdd. Why this is so ? Is there (Hardware)

Stories similar to [ubuntu] system monitor shows single core

hi all,

I just installed Unbuntu 12.10 (32 bit version) on a ZOTAC ZBOX (the box print label says it has an Intel Atom D2700 dual-core, 2.13 GHz). The problem is the system is running very slow. I noticed two issues:

1- the system monitor shows 4 CPUs all running 50% to 80% even with the system sitting idle.

11.10. No matter what I set in the Mixer I can't get sound through the headphones.

One stopped processor 46 weeks 3 days ago

I have an intel Extreme X9850 - (4 cores). System monitor shows processor 0 at 0%. Others are busy. It looks like the processor has stopped. Can I restart the processor without rebooting? This has happened once before. Rebooted and all was back to normal. System has been running fine.

processor question 3 years 11 weeks ago

I'm looking at new laptops. I'm considering a Dell that has an Intel Core Duo 1600 MHz processor.

My questions:

Is this a 32 bit or 64 bit processor?

Will this processor handle VirtualBox? (I'm told my p4 isn't capable of running two os)

What is the difference between the Core Duo and the Core 2 Duo?

My computer won't restart, only a clean boot works. When I restart it, it shows VideoCard info and freezes at Intel's screen, before the "BIOS settings" appear. I've ran out of ideas, any help?

I have a January, 2009 Macbook5,2. It has an Intel Core 2 Duo 2Ghz processor.

Since installing Xubuntu 12.04, it runs very slowly. The CPU gadget in the top panel shows only 1 dark column to the left of the graph (apparently 1 per CPU/core, as my desktop machine appropriately shows 4 columns).

I have Slackware 13.1 installed on 2 laptops and a desktop. The desktop is an older Dell XPS 410 with 4 gigs of ram and a 2.8gHz dual core pentium D, One laptop is a Sony Vaio with a dual core processor and 2 gigs of ram, and the other is a Dell Studio 15 with 3 gigs of ram (can't recall the processor).

For those of you who think that dual-core is so last year then have I story for you. The video we have here shows the TI dual-core OMAP 5 application processor for mobile devices outpacing the quad-core Tegra 3 processor from Nvidia. For those that don’t know the OMAP 5 sports ARM’s new and improved Cortex-A15 CPU design.
