Ubuntu Installation :: Can't Detect Core 2 Duo As 64Bit
Jan 10, 2010
I'm trying to install Ubuntu 9.10 64Bit on my Intel Core 2 Duo Laptop, but it says "This kernel requires an x86-64 CPU, but only detected an i686 CPU. Unable to boot - please use a kernel appropriate for your CPU." However, I'm able to use Win 7 64bit and Win Vista 64bit on the same machine.
I am facing problem in installing/ configuring the Broad com wifi card (BCM4727) on fedora Core 13. how to install the BCM4727 on core 13. The os is 64 bit .
I have a new hp g62 notebook pc with intel core i5 m469 @ 2.53 GHz, 64 bit operating system. I wish to use GCC to develop for msp430's, arm7/9. Which distro would work best for this hardware?
I can't able to create more than 28 spawn bash in fedora core 7 (2.6.25.4 kernel) linux 64 bit machine. I can able to create 1015 spawn bash in 32 bit fedora 7 core. Script I have used for both 32 bit and 64 bit:
In the past, I've deployed new 64 bit systems and I've worked on and developed on 64 bit systems. But until a week ago, my workstation was a 32 bit system. Now, it is a 64 bit quad core Phenom II system, and I suppose I need to start the migration to 64 bit Linux. I do not want to blow off my system and rebuild it. This particular system dates back a decade and through many many updates. There is some digital debris in it, but there is also a fair amount of customization that I have implemented either for my own purposes or for customers, and to lose that customization would represent a headache for me.
What I want to do is install a 64 bit system over top of the 32 bit system. It is my hope that doing this would install the necessary 64 bit libraries, while not impacting the existing 32 bit libraries (except with some possible symlink problems). I then, hopefully, could boot into a 64 bit kernel while still running 32 bit programs. Is this feasible? My backup system is comprehensive; I COULD just try it and back up if my system became hosed. But I'd rather not; I have a lot of work to do and I'd rather not learn by doing in this case.
I would like to install the new Ubuntu 11.04 64bit. I first booted from usb to see how the new release behaves on my laptop(sony vaio eb3m1e). The thing that does not work as it should is that the OS can't detect the GPU which is an ATI radeon 5650, when i click the additional drivers icon in order to install the proprietary drivers I only see the "no proprietary drivers are in use on this system". How can I make the OS detect the GPU?
I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?
Ive installed fc11 on my laptop (IBM lenovo R400). My work has a proxy which we must go through. I have set the proxy addresses in System Settings->Network Settings-> proxy. I have also run export [URL].. All seems to be ok, yum works from the command line, konquer goes out to the net just fine. However firefox wont connect to the internet no matter. The only way at the moment is to manually set the proxy in firefox.This doesnt seem right? Surely FF should pick up the system proxy? Does anyone have any ideas about this one?
i am looking for a rpm package to run openoffice because when i try to install it it come up with i need this openoffice.org-core = 1:3.3.0-9.3.fc14 but i cant find it anywhere on the net?
i am running gigabyte GA-M68M-S2P and AMD sempron 2.7. the problem is when i try to run dual core. it will boot and run for 2mins then it crashes. single core runs perfect.
Earlier I was using Fedora 14 32 Bit with pae kernel. It used to detect 3.8 GiB of RAM (out of 4GiB). Now I've installed Fedora 15 64 Bit, but it detects only 3.7 GiB of RAM.... I've not installed any kernel patches.

I have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

I have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.
I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.
Assume someone bind a particular process to a particular CPU core(In multi core machine) by using sched_setaffinity() like functions. Then how we can get that process running core id and CPU core utilisation of that process on that running CPU core(Pragmatically or by a Linux command)?.
I've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?

I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
We have a small cluster of 20 HP systems, all running CentOS 5.3 in an NFS-root environment. Half are quad-socket, quad-core Xeon E7340 @ 2.40GHz (total 16 cores), the other half are 8-socket, quad-core Opteron 8354 (total 32 cores). All systems have a Mellanox Infiniband adapter ("Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)")
With kernel 2.6.18-128.1.6.el5, infiniband works fine on all systems.
With the update to kernel 2.6.18-164.11.1.el5 (and both types of node running the same NFS-root image), the 16-core Xeons still work fine. Infiniband no longer works on the 32-core Opterons. Specifically, either the ib0 interface fails to appear, or it does appear but when configured with an IP address, doesn't actually work. In either case, loading the IB kernel modules takes a long time, but I haven't instrumented the load script yet to see which module, if any, is at fault. More errors listed below.
However, if I tweak the BIOS of the 32-core systems to reduce the per-socket core count to 2 (so effectively 8-socket, dual-core, down to a total of 16 available cores), Infiniband starts working again. Putting it back to 32-cores makes it fail. Booting the older kernel makes it work again. In summary: old kernel, IB works on all systems. Newer kernel, IB only works on 16-core systems.
Updating the IB firmware from 2.5.0 to 2.7.0 (latest available) doesn't help. I also did a full 'yum update' to make sure that libmlx4, openibd all other associated packages were up-to-date. Doesn't help either.
Some errors that appear on 32-core nodes:
ib_query_port failed (-16) for mlx4_0 ib_query_port failed (-16) for mlx4_0 mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16) mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?
I installed maverick meerkat but for some reason there was no install to free space option so I installed onto 32gb of my 170gb windows vista installation. I NEED THAT INSTALLATION. Maverick Meerkat cannot detect my windows installation!
I'm trying to install Kubuntu 9.10 on my machine (I had the same problem with Kubuntu 9.04). The machine is:
- Core 2 Quad 6600 - Nvidia 7600 GS - Two disk seagate 500 in mirroring raid software
When I try to install Kubuntu, after disk partition, my system dosn't see the CD. He tell me to insert disk into drive but I doesn't touch it. I resolved this mounting an external hard disk into /cdrom. After this, the installation continues until the step "select and install software". At this step, the installation procedure tell me an error. During this error, in the other console, I've this:

Questo può voler dire Jan 19 21:58:09 in-target: che è stata richiesta una situazione impossibile oppure, se si sta Jan 19 21:58:09 in-target: usando una distribuzione in sviluppo, che alcuni pacchetti richiesti [Code]....
I have a new F12 install, and my syslog is filling up with messages about USB. I have 2 USB devices plugged in directly to the mobo (bluetooth keyboard receiver, touchscreen), and it keeps redetecting them and then disabling the port for some reason.
