• Installing 12.10 on Dell r710

  - by user115490

  I have been trying to install Ubuntu 12.10 on a Dell r710. I have 6 disks in each 2 TB. I setup a raid 5 in the HW raid controller with all drives, and proceeded with the OS install. When the partitioner runs it fails to create / for some reason. I then tried just setting up a simple raid 1 with 2 drives in the HW controller, and doing the OS install again. The installer runs fine this time. Once trying to boot I then get a kernel panic of 'Target File System doesn't have requested /sbin/init' as well as a bunch of 'deleted inode referenced'. Can someone tell me what I am doing wrong here?

• 3TB non-boot hard disk on older motherboard

  - by Bcos

  It is time to expand the capacity of my Ubuntu home file server so I would like to purchase some 3TB hard disks. However, I am concerned with potential compatibility issues. I've tried searching around but I haven't found information which clearly addresses my particular situation. My server is running Ubuntu 10.04 on an Intel P35 chipset based system. The motherboard does not support UEFI (and, by extension, GPT?). However, Ubuntu does support 2TB disks. Will I be able to properly utilize these new disks, or does the motherboard limitation trump all else? The boot disk is <2TB and will not be updated nor am I dual-booting; these disks will be used strictly as slaves in a pure Ubuntu environment. I'd hate to pull the trigger on these new disks just to be unpleasantly surprised, so any feedback is appreciated. Thanks!

• Grub Doesn't Load after Update

  - by Parris

  Hi Everyone, After I updated ubuntu (I believe it was most likely a kernel update) and restarted I selected ubuntu from the windows boot loader (I am using wubi). At this point I would usually land on the grub loader; however, I see something about NTFS file not found and a couple other screens flash then the computer restarts. I have tried pressing ESC right after to try and get some options, but I think grub is just not found or something... Not sure what is going on.. Any help would be much appreciated :). Thanks!

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Get and install Nvidia GeForce 8400 GS driver

  - by williepabon

  Recently, I changed my OS kernel from 10.04 to 11.10 (bugs), but after doing it, the video driver for the 8400 GS disappeared (was there in 10.04). I worked out the same procedure I did to install it in 10.04, mainly, sudo apt-get --purge remove nvidia-current sudo apt-get --purge autoremove sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get -y install nvidia-current but it didn't work even though the commands seemed to install the driver without problems. Right now my machine is working with the standard drivers, as shown. williepabon@WP-WrkStation:~$ sudo lshw -C display [sudo] password for williepabon: *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:05:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:de000000-deffffff memory:c0000000-cfffffff memory:d0000000-d1ffffff ioport:cc80(size=128) memory:dfc00000-dfc7ffff Any suggestions to correct the problem?

• Linux 3.6 sort en version stable : veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4

  Linux 3.6 sort en version stable ajout de la veille hybride, TCP Fast Open, VFIO, améliorations de Btrfs et suppression du cache IPv4 Linus Torvalds vient d'annoncer la sortie de la version 3.6 stable du Kernel Linux. La nouveauté phare de cette mouture est l'introduction d'un mode de veille hybride, longtemps supporté par Windows et Mac OS X. L'option Suspend to Both (Veille et hibernation combinée) permet de suspendre l'activité de l'ordinateur tout en conservant le contenu de la mémoire vive sur le disque dur (uspend-to-disk) et ensuite une sauvegarde du système dans la mémoire (suspend-to-RAM). Le grand avantage de ces deux techniques liées est qu'elles permettent le retou...

• Second click on a launcher icon with more than one window open doesn't do a scale of that application

  - by Eastsun

  In unity, if I click an icon in the launcher with multiple windows open it doesn't show me all open windows for that application. However, this works in unity2d. I known there have a same question asked before: here! But I think my condition is not as same as the previous question. ubuntu 12.04 64-bit unity 5.16.0 kernel linux 3.2.0-33-generic gnome 3.4.2 Edit I just find a interest thing: There are four workspace, label it as A, B, C, D. If I firstly open two windows of firefox in A, as I mentioned above, second click on the firefox icon does nothing. But after I open a window of firefox in B, the second click on the firefox icon in workspace A magically works!! And then, I open two terminal in workspace C, second click doesnot work until I open another terminal window in D. So, it seems that the second click only work if the application be opened more than one workspace.

• What is the best stucture of SEO friendly URL?

  - by Aajahid

  I'm working for a website to convert the website URL to an SEO friendly URL. I plan to use this: mysite.com/category-name/pageid-123-page-name I looked at some similarly categorized, highly ranked websites. They have the same structure, except for one thing. In one case, the URL format was thissite.com/category-name/pageid-123-page-name.html Another was thatsite.com/category-name/pageid-123-page-name.php Now I know the text in URLs help with SEO. Is it more helpful to have a file extension? If yes, which one is better? Or if my current plan is okay, will it be better with a / at the end?

• How can a regular user be notified of a required reboot?

  - by Andre

  I am administrating multiple machines on which I am admin and the users have not admin-rights. The machines are configured to pull and install updates automatically. A new kernel will require a reboot. On Ubuntu Precise this was made visible to the user through the color change of the shutdown-menu in the upper right corner (it turned red). Now, on Ubuntu Trusty, there is not color change anymore. Also, the Update Manager will not pop up for regular users reminding them of an outstanding reboot. How can a regular user know that a reboot is required?

• usb stop working

  - by miguel

  I'm using Xubuntu 12.04 on a 64 bit Intel core duo laptop and the 3 USB 3.0 ports stopped working if I do not use the mouse. I updated the kernel to 3.9 but the bug persists. I googled too much and the few reponses I got cannot fixed this. The only solution is shuting down, unplugging and then plugging them back, then all works fine. But after half an hour or two days the bug reappears. How can I solve this? Thanks and excuse my poor english.

• How do I sort account names alphabetically in Thunderbird?

  - by Sri

  I just upgraded to Ubuntu 12.04 and Thunderbird 13.0.1. I had 2 accounts earlier in Thunderbird: [email protected] [email protected] I also had another account on SeaMonkey: [email protected] which I imported into Thunderbird. Now the account order I want is: [email protected] [email protected] [email protected] but it shows: [email protected] [email protected] [email protected] I couldn't find any option in Thunderbird to sort them as I want. I came across a 3rd party extension but I avoid using such extensions. Is there any other way this can be done?

• How to name a clamp function that only clamps from one side?

  - by dog_funtom

  Clamp() is a function that ensures that provided variable is in provided range. You can find such function in .NET, in Unity, and probably anywhere. While it is useful, I often need to clamp my value from one side only. For example, to ensure that float is always non-negative or always positive (like radius value from inspector). I used names ClampFromAbove() and ClampFromBelow(), but I wonder if such names is good or even grammatically valid in programming-English. Also, it probably make sense to distinguish non-negative case too. How'd you name such function? Something like EnsureNonNegative()? My intention is creating pair of extension methods and use them like this: var normalizedRadius = originalRadius.ClampFromBelow(0.0001); var distance = someVector.Magnitude.ClampFromAbove(maxDistance);

• How can I install the Realtek RTL8111E version 8168 driver?

  - by Unknown_Fool

  I downloaded and extracted the latest Linux driver version from Realtek. I read the readme file and it instructed me to run ./autorun.sh as root. I did that. It compiled the driver for my kernel, removed the old default module, but then it fails to install the new 8168 module. It claims that it can't be found. Can this driver be installed manually? Is there a way to fix autorun.sh so it can install properly?

• Ubuntu doesn't boot after upgrade

  - by Hugtrw

  I updated to 12.10 and the OS will not load. I used the boot repair cd, and the only thing that works is the monodeset option in the kernel and the graphics are terrible, mouse disappears and unity will not load. Ubuntu 12.04 ran great. On a clean install of 12.10 Ubuntu wont even load to install unless under using monodeset. I get left a terminal like screen with just a blinking bar. I'm using a HP Compaq NC6400 Laptop, Ubuntu 32-bit, 2gb ram.

• When to use event.initMouseEvent for simulating mouse clicks?

  - by Protector one

  I wonder if there are benign use-cases for simulating mouse clicks using event.initMouseEvent. I found that it is used for creating pop-under ads in the following way: var e = document.createEvent('MouseEvents'); e.initMouseEvent('click', true, true, window, 0, 0, 0, 0, 0, true, false, false, true, 0, null); a.dispatchEvent(e); This code simulates a click on the opening browser window, to force the newly opened window beneath it. Evil. I'm thinking of simply preventing all simulated clicks in my own browser via a browser extension, but I wonder if I might break useful websites and behavior in the process. Therefore I wonder what situations justify simulating mouse clicks, and if there are big sites that use it in non-evil ways.

• alx driver not working properly

  - by user292768

  My alx driver seems to be working fine for everything except apt-get. I can navigate to web pages, the ping command works just fine, but whenever I try to do apt-get update or apt-get install it hangs on trying to connect to whatever archive it's trying to pull info from. There's no error message, nothing to imply that it can't connect, it just hangs there and does nothing at all. I've tried re installing alx, upgrading/downgrading my linux kernel, downloading source and building alx from scratch, etc etc but nothing works. Does anybody else have this problem/know how to fix it?

• Mount Bluetooth USB in VirtualBox

  - by GoBrewers14

  I originally asked this question here Python Module PyBluez Error and have narrowed it down to basically I can't get VBox to recognize my bluetooth USB. I'm on a MAC OS X 10.9.2. I've installed VirtualBox as well as the Extension Pack and I've installed Ubuntu Desktop 10.04.4 on the VirtualBox. I've searched several Mac forums and this seems to be a common problem w/o a clear solution. Anyways, the question is how can I get VirtualBox to let Ubuntu recognize my bluetooth USB? I've checked 'Enable USB 2.0 EHCI Controller' and added my two bluetooth devices to the filters list. and when I click here to mount the USB I get this error message... Any ideas? Thanks, John

• Parallel Threading in Multi-Language Software?

  - by Smarty Twiti

  I'm developing a software that contain many modules/Daemon running in parallel manner, what i'm looking for is how to implement that, i cannot use Thread because some of those modules/Daemon are perhaps implemented in other languages (C,java,C#...). For example I'm using C for Hooking Messages exchanged between Windows kernel and top level applications, Java/C# to use some free library to simply parse XML(for example) or to accept and execute commands over the network..this can be done by C Language but just to improve productivity... Finally for GUI I'm using Ultimate++ (c++) that is like the main process that call and monitor(activate/deactivate/get state) of all other modules/Daemon through an interface. I admit that the development of each module/Daemon in a separate language greatly facilitates maintenance, but especially I am obliged to do that.. What is the best practice way to do that ? All helps will be appreciated.

• Should I create repositories with special functions like getStaffActive()?

  - by Parhs

  I have seen lots of articles but none really help me. That is because I want to use dapper as a DAL. Should I create repositories with special functions? Like getStaffActive()? If I use repositories I can implement with dapper-extension a generic crud I have no idea how to handle database connection. Where to open the connection? If I do this at every function then how am I supposed to use transaction scope? Somehow the repositories I work with should share a connection in order transaction to work. But how to do this? Openning connection in BLL? If I use queries and execute them directly then still the same thing.

• ASUS VX-6 Laptop Wireless not connecting

  - by user2152790

  Someone posted a script a couple days ago, here is my output.Pastebin I can see wifi SSIDs in network, but cannot connect to mine. The only time wifi worked on 13.10 was in the Live CD, but wifi stopped working as soon as install process started. Did below but made no difference. sudo apt-get install bcmwl-kernel-source sudo modprobe -rv brcmsmac sudo modprobe -v wl What I do next? I tried Software&Updates and it showed 1 proprietary driver in use. This sounds like a WPA/WPA2 issue? Wifi works when I tried Zorin OS 7.1, wifi always worked in windows 7.

• Ubuntu 14.04 Fatal Exception

  - by user286534

  I use Ubuntu 14.04, 64-bit. I installed Virtualbox and was testing another Linux OS (Deepin). My system froze and I could not get to a TTY session to reboot. I had to do a hard restart and when Ubuntu restarted I got various error codes one of which was "kernel panic - fatal exception in interrupt" Booting to Advance mode and attempting repairs did not work (fsck, grub repair, etc) I reinstalled Ubuntu and chose the option to keep my files intact. I can now access my system but many programs I have installed do not work. My question is; I have a Deja-Dup backup (but only of my Home directory), is it better to restore my backup files or do I have to reinstall all of my programs? The weird thing is, the programs I verified using the Software Center to see if they were installed are checked as installed, but won't appear in Dash.
