  • Can I copy large files faster without using the file cache?

    - by Veazer
    After adding the preload package, my applications seem to speed up but if I copy a large file, the file cache grows by more than double the size of the file. By transferring a single 3-4 GB virtualbox image or video file to an external drive, this huge cache seems to remove all the preloaded applications from memory, leading to increased load times and general performance drops. Is there a way to copy large, multi-gigabyte files without caching them (i.e. bypassing the file cache)? Or a way to whitelist or blacklist specific folders from being cached?

  • Problem with Ubuntu 12.04 boot

    - by Etienne
    I'm having a problem as stated in the title regarding bootup. What happens basically is that after grub is loaded the system doesn't boot. I get a black screen with cursor blinking then the screen darkens ( switches off ) and keyboard is unresponsive. Today I have re-installed everything on a new hard drive and it happened again. This has been observed when running kernel 3.5.0-30 and 3.5.0-28. System is an HP6550b. Can someone help me on this please ? Many Thanks!

  • Trouble installing 12.04 from cd, blank screen with cursor

    - by Master Morality
    I should preface this with saying that this is not my first rodeo. I started playing with Linux in 1999 (Red Hat) and I'm currently typing this on a ThinkPad running 12.04... When I put in the live cd, I boots, and I can get to the option menu to decide whether to install/run etc, but at any point beyond that I get only a single caret. I can type stuff in, but it goes no where. I've tried the usual stuff like running with nomodeset (thinking it was the intel HD400 graphics, but it is integrated graphics...) here is the setup: ASUS p8z77 pro (with the Atheros AR9485 wifi supposedly, but I'm not that far yet) i7 3370k 8gig X 2 G.Skill Crucial M4 (256 gig) LG Super-multi DVD re-writer no video card UPDATE: I though may be it was a bad image on the CD, so I downloaded another iso, and used a USB disk. now it boots to a blank screen. I can see the "press any key to get options" screen, but after that, it just goes to a blank screen.

  • Ubuntu 11.04 windows XP dual boot problem

    - by Bernie
    I have installed Ubuntu 11.04 direct from installation disk in a separate partition alongside an existing Windows XP installation. Ubuntu operates fine. I can see the old XP file system and the other network computer and access the internet. The problem is when the computer starts I get the boot selection list for Ubuntu or XP; but I am not allowed to select Windows XP (I cannot scroll down the list with tab or arrows keys). This would be fine for me but the computer is used by other people who are only familiar with windows XP at the moment. I have downloaded and run Boot Repair. Below is the link to the resulting data. http://paste.ubuntu.com/1082944/ I hope you can help solve this problem. I look forward to hearing from you. Kind Regards Bernie.

  • Ubuntu will not load up from my USB

    - by Ryan Mungwira
    I have a Sony Vaio Duo 13 and I am trying to get Ubuntu 13.10 to run on a partition on my Ultrabook but it will not load up from the USB drive. It goes to the black screen that asks if you just want to Try Ubuntu or if you want to Install it. I click just to try and it will not load. It acts like it is going to start up but then it just goes to a blank black screen and then I have to a hard restart. It does that when I click install as well. And I have tried disabling the Secure Install on my computer as well and nothing happens! What do I do?!?

  • Inside Red Gate - Be Reasonable!

    - by simonc
    As I discussed in my previous posts, divisions and project teams within Red Gate are allowed a lot of autonomy to manage themselves. It's not just the teams though, there's an awful lot of freedom given to individual employees within the company as well. Reasonableness How Red Gate treats it's employees is embodied in the phrase 'You will be reasonable with us, and we will be reasonable with you'. As an employee, you are trusted to do your job to the best of you ability. There's no one looking over your shoulder, no one clocking you in and out each day. Everyone is working at the company because they want to, and one of the core ideas of Red Gate is that the company exists to 'let people do the best work of their lives'. Everything is geared towards that. To help you do your job, office services and the IT department are there. If you need something to help you work better (a third or fourth monitor, footrests, or a new keyboard) then ask people in Information Systems (IS) or Office Services and you will be given it, no questions asked. Everyone has administrator access to their own machines, and you can install whatever you want on it. If there's a particular bit of software you need, then ask IS and they will buy it. As an example, last year I wanted to replace my main hard drive with an SSD; I had a summer job at school working in a computer repair shop, so knew what to do. I went to IS and asked for 'an SSD, a SATA cable, and a screwdriver'. And I got it there and then, even the screwdriver. Awesome. I screwed it in myself, copied all my main drive files across, and I was good to go. Of course, if you're not happy doing that yourself, then IS will sort it all out for you, no problems. If you need something that the company doesn't have (say, a book off Amazon, or you need some specifications printing off & bound), then everyone has a expense limit of £100 that you can use without any sign-off needed from your managers. If you need a company credit card for whatever reason, then you can get it. This freedom extends to working hours and holiday; you're expected to be in the office 11am-3pm each day, but outside those times you can work whenever you want. If you need a half-day holiday on a days notice, or even the same day, then you'll get it, unless there's a good reason you're needed that day. If you need to work from home for a day or so for whatever reason, then you can. If it's reasonable, then it's allowed. Trust issues? A lot of trust, and a lot of leeway, is given to all the people in Red Gate. Everyone is expected to work hard, do their jobs to the best of their ability, and there will be a minimum of bureaucratic obstacles that stop you doing your work. What happens if you abuse this trust? Well, an example is company trip expenses. You're free to expense what you like; food, drink, transport, etc, but if you expenses are not reasonable, then you will never travel with the company again. Simple as that. Everyone knows when they're abusing the system, so simply don't do it. Along with reasonableness, another phrase used is 'Don't be an a**hole'. If you act like an a**hole, and abuse any of the trust placed in you, even if you're the best tester, salesperson, dev, or manager in the company, then you won't be a part of the company any more. From what I know about other companies, employee trust is highly variable between companies, all the way up to CCTV trained on employee's monitors. As a dev, I want to produce well-written & useful code that solves people's problems. Being able to get whatever I need - install whatever tools I need, get time off when I need to, obtain reference books within a day - all let me do my job, and so let Red Gate help other people do their own jobs through the tools we produce. Plus, I don't think I would like working for a company that doesn't allow admin access to your own machine and blocks Facebook! Cross posted from Simple Talk.

  • Welcome to our Friday tips series!

    - by Chris Kawalek
    Today we're starting a brand new blog series. For your Friday afternoon reading, we'll be posting a technical tip or question and answer on a technical topic. We'll start by introducing ideas on our own, but we'd really like it if you were involved and asked us questions via Twitter! Tag your tweet with #AskOracleVirtualization and we'll consider your question for the blog. Today's tip is on Storage and Oracle Virtual Desktop Infrastructure: Question: I run Oracle Virtual Desktop 3.4.1 on Solaris and use a local ZFS storage pool.  How should I configure my ZFS ARC cache?  Answer by John Renko, Consulting Developer, Oracle: Oracle recommends about 5G of ARC cache per template in use to achieve up to a 90% disk read offload. Set your ARC min=max to reserve the maximum amount of your remaining memory for your running VMs. In /etc/system: set zfs:zfs_arc_min = 5368709120 set zfs:zfs_arc_max = 5368709120 The amount you need to reserve will depend on your template but this has proven to be a great start for a typical windows 7 VM running productivity applications.

  • Major problem with Nvidia drivers

    - by user38580
    Since I decided to use Ubuntu -yesterday- I've been struggling with the drivers. It isn't recognizing my optical disc drive nor my video card, a Nvidia 8500gt. For the matter, here's how I "successfully" installed the .run driver downloaded from Nvidia's website: The terminal wouldn't let me start the installation because the X server had to be shutdown, so I pressed Ctrl+Alt+F1 Then, I used: sudo service lightdm stop cd /(directory where the nvidiaupdate.run was) chmod +x nvidiaupdate.run sudo ./nvidiaupdate.run The installation began and got completed, but unfortunately it crashed Ubuntu's UI, invalidating the OS for me. All that would appear was a DOS-like screen with reports. I'm new to Linux, so I really would appreciate any help given. For now, I'm sticking to the additional drivers, but even with it Ubuntu doesn't show my video card in the informations of the system. Forgive my bad English.

  • default mount point changed for external HD

    - by JhmL
    The default mount point for my external HD changed when upgrading from 13.04 to 13.10. Now the username is added as an extra level before the hd label. So it used to be /media/nameofhd and now it became /media/username/nameofhd This breaks a lot of links I have set up to this disk. I know that I can mount it manually and even automatically through /etc/fstab. What I want to know is why this behaviour changed and how I can change it back to the original? blkid and fdisk don't show anything suspicious. thx!

  • grub2 update-grub puts wrong UUID in grub.cfg for system with separate /, /boot and /home partitions

    - by keepitsimpleengineer
    It is putting in the UUID for the boot partition and not the / (root) partition. It's grub2 (1.99-21ubuntu3.1) on Xubuntu 12.04. UPDATE: ? I ran Boot Info Script 0.60, here are results? The boot info script is too big for askubuntu, but is here. The system not booting is on /dev/sdh. The booted disk, Xubuntu 12.04, is /dev/sdb. /sdh2/etc/fstab is at line 1073. The incorrect UUIDs are at line 945 and 954. "blkid" putput is at line 318. It is putting the UUID for "boot" versus "root" in boot.cfg, line 937. I have noticed that the relationship between physical drives and names in /dev vary depending on which system is booted.

  • Computer Freezes After GRUB

    - by paulmcg421
    Ok so I've just built my first computer and have got it running, here are the specs: Asus P8Z68-V PCI-E LX Motherboard, Intel Core i5-2500K, Patriot Memory 8GB (2 x 4GB), Viper Xtreme Series PC3-15000 1866MHz CL9 Division 2 Edition Memory (PXD38G1866ELK), Gigabyte ATI Radeon 6850 820MHz 1GB PCI-E HDMI OC Windforce 2x 500w Ezcool 24pin psu as standard. The only thing I haven't bought new is the hard drive, it's a 250gb that I removed from an Acer Aspire M5100 that I was using till now with no OS Problems. On start up it runs fine but is unresponsive after the GRUB menu disappears to load Ubuntu (Oneric Ocelot). The keyboard lights then turn off and the screen eventually returns that there is no signal. Is there anything that I could be missing from building? (This is my first attempt at building my own PC) Any input would be appreciated, thanks !

  • Switching my legacy desktop back to Windows XP from Windows 7

    - by Kevin Shyr
    I was happy with Windows 7 at the beginning, until I started to add in the peripherals.  Windows 7 was never able to recognize any of my PCI video card (I know, I know, we should be in the DVI age). Anyway, I went through another 4 days of trouble setting my computer up with dual monitor in XP (also did a bunch of other things like getting rid of my sound card and taking the computer off RAID. Kind of feel stupid to put the computer on RAID in the first place because now I can have 2 drives: double the page files program seems to run faster Microsoft Sync toy 2.1 takes care of my backup needs (Thank god they solved the network drive issue) As of last night, the system is running beautifully.  I still have a laptop with Windows 7, but even that is in dual boot mode.

  • Issues With IIS Hosting Two Domains From Same Folder [closed]

    - by Bob Mc
    I have two different domain names that resolve to the same ASP.Net site. Both domains are hosted on the same server, which runs Windows Server 2003 and IIS6. The sites are differentiated in IIS Manager using host headers. However, both of the sites point to the same folder on the local drive for the site's page files. I am occasionally experiencing an ASP.Net error that says "The state information is invalid for this page and might be corrupted." I'm the site developer so I've addressed all the relevant code-related causes for this issue. However, I was wondering whether having two domains/sites sharing the same folder for an ASP.Net application might be causing this intermittent error. Also, is this generally a bad practice? Should I make separate, duplicate folders for each of the domains? Seems like that can become a maintenance headache.

  • Swap File, Mount point, GRUB2

    - by Mike Green
    Windows 7 with 1gb RAM Hi. I am installing Ubuntu 12 onto a 20gb ext3 partition. I have 100gb free disk space. The install asked me to choose a swap space. Do I have to allocate another partition for the swap space, and if so, what size should it be? I installed without allocating a swap space. Can I allocate a swap space after the install? The install asked me for a mount point. I chose /. Is this okay? I also want to ensure that GRUB2 will be installed within the UBUNTU partition. Is there an option for this on the install? (I will use EasyBCD to select Windows7 or UBUNTU.) Thanks for your help, M...

  • Missing feature in Hyper-V from Virtual PC

    - by Kevin Shyr
    One thing I really miss is the ability to create shared folder between host and guest.  Virtual PC does this well, you can create Shared Folder to be used every time, or just this one.  I have read some posts on how to do this.  Some people suggest using ISO Creator to package up the files and mount the image to DVD drive, but what I need is truly a "shared" environment, so I'm currently looking into creating Virtual switch and creating an internal network between the host and guest.  Let's see how that works out. I would have loved to give Virtual SAN Manager a try, but I don't have a local Fibre Channel to set one up. I guess this might be an extension to my original post:  http://geekswithblogs.net/LifeLongTechie/archive/2011/05/05/windows-virtual-pc-vs.-hyper-v-virtual-machines-vs.-windows-virtual.aspx

  • Ubuntu 13.04 is showing some error while opening my computer

    - by Singh
    Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

  • How do I run update-grub from a LiveCD?

    - by Kelley
    Okay, so I did something stupid. I was trying to clean up my Grub entries, and accidentally removed all of my Linux kernels from Grub (they're still on the hard drive). So now, obviously, Grub doesn't give me any way to boot into Ubuntu; I can boot into Windows just fine, but Ubuntu isn't even listed. So I just want to run "sudo upgrade-grub" somehow to restore Ubuntu to the list. I can boot from a LiveCD, but once there how do I run that command? (My Ubuntu installation is on sda5, by the way.)

  • Black screen white cursor and can't boot from live disc that I installed from just yesterday (Ubuntu 12.04)

    - by Luke
    So, I've decided to change to Ubuntu from Windows 7 after reformatting. Install goes smoothly, I've set everything up, and it works for a day. It crashed when I had a full screen video, froze, so I rebooted, and now I can't get past the black screen with flashing white underscore cursor. If I wait a while, I get "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press any key" I've tried that, removed any boot options but the DVD drive, even tried my Windows 7 boot CD as well. Nothing boots, so I can't do anything. This is on an Asus A52N laptop, and all I can access now is the BIOS (version K52N 217), as far as I can tell.

  • How to get past black screen with mouse icon while installing on Gateway MX6920?

    - by tom kruse
    I have an old Gateway MX6920 laptop that got a virus on its hard drive so I put in a new one from another laptop. When i turn it on it tries to load Windows but fails so I'm going to try to put Ubuntu on it (because I heard it's a good OS). I downloaded the 32-bit desktop version of Ubuntu and burned it to a CD. I put the CD in the computer, went to the boot menu, and selected CD-ROM. The computer tries to boot but stops at a black screen with a mouse icon sitting in the middle of the display. I have no idea what's going on, so please help.

  • Cloud Computing in words of one syllable

    - by harry.foxwell(at)oracle.com
    A colleague of mine challenged me to describe Cloud Computing in words of one syllable so that even his 80-year-old mother-in-law could understand the concept.  Hmmmm...The Cloud lets you do all your work on the Web or on your own net. It lets you set up your own work; no one has to set it up for you.  When you need more disk space, the cloud makes it for you.  When you need more speed, the cloud adds more gear to make your jobs go fast.  You share the cloud with more than just your own work, and you just pay for what you use.  The cloud is not new; this type of work has been done for years; just the word is new.  Now you know what the cloud is.  Or not.
