• Server asks for username and password on boot

  - by Jon

  I installed the Ubuntu server 12.04 easily, however, when I boot it asks for a username and password. I don't know my previous username or password from Windows XP. I am currently trying to install any version of Ubuntu I have in my arsenal to recover the PC, but all intents so far have failed. They worked on other computers but not on this one, the error I get is No DEFAULT or UI configuration directive found! I have tried all the solutions found on this site but to no avail. I don't have a Windows Ultimate boot disk and I'm out of CDs to burn. I can, however, make live USBs. Any Suggestions?

• Event Handlers and Automatic Postback in ASP.NET 3.5 Web Controls

  In one of last week s tutorials Creating Database-Driven ASP.NET 3.5 Input and List Web Controls you learned how to create a dynamic input web control that instead of setting values statically stored its list and values directly from the MS SQL server 2 8 database. This tutorial is a sequel to that article. It deals mostly with the server side coding aspect of dynamic web controls. It is recommended that you read the earlier tutorial first as the Visual Web Developer Project in that tutorial will be used extensively in this article....

• Trying to boot from USB on Asus q200e-bhi3t45 just brings me to grub menu

  - by Krash Kharma

  It's been a struggle every time I've tried to change my OS on this machine. I honestly don't even know how it works whenever it does. I've somehow managed to get Windows 7, Windows 8, Mint 14, Ubuntu 12.04, and 12.10 to work at random times but it's always after struggling with it and googling for random chance fixes and suddenly something clicks and it loads from usb, but 99% of the time, every time I try to boot from USB to install a distro (in this case, I'm trying to get ubuntu-12.04.2-desktop-amd64.iso to work) my pc just comes up with a grub menu ("Minimal bash-like blahblahblah - grub ") I don't know why it works when it works. Right now I've tried everything from with/without Fast Boot in BIOS, with/without CSM, with/without secure boot, to changing BOOTx64.EFI to bootx64.efi to downloading a new bootx64.efi to copying it to every folder on the usb.... It makes no sense to me. Sorry if this has been asked before but I can't find anything

• Is NTFS-3G safe for writing?

  - by katrmr

  These days, I have to use the NTFS-3G driver to write to an NTFS drive (which will later be used in Windows). But I still remember the olde times of Linux ntfs driver which clearly said in the docs: 'If you write to an ntfs volume, run our special program afterwards which will clean up the damage done.' So, I read through the man, the docs, the Tuxera site and Askubuntu and found no discussion of the write-safety of NTFS-3G. The only thing that was mentioned somewhere is that the driver doesn't support the NTFS journal. So, the question is, can I use NTFS-3G and be sure that I will later read what I have written to the files? Won't, for example, Windows find the journal entries missing and 'clean up' the data according to its own faulty understanding?

• Boot error aftter clean Ubuntu 13.04 install: [Reboot and select proper boot device]

  - by IcarusNM

  I am having the same problem as this guy where a fresh Ubuntu install completes beautifully but will not boot. I get the ASUS (?) "Reboot and select proper boot device" error, first with Xubuntu 13.10 and after finally giving up there, and Xubuntu 13.4, I am back to regular Ubuntu 13.4. ASUS motherboard Z77, Intel chipset. Standard internal SATA 500GB HD. 64-bit. All-new hardware less than 3 months old. It was running Ubuntu 12.04LTC great until I tried this upgrade. I have re-installed from scratch every which way: with LVM, without LVM; with the default partitions, with my own partitions. With ext3 or ext4. Alongside; replace; upgrade. No difference. On the last two tries, I have booted afterward from the same USB stick, downloaded and run boot-repair, and now I guess I am off to the boot-repair support email with my URLs from that. It did all kinds of cool stuff but ultimately made no difference. I never got anything like this with Ubuntu 12.04. I've now probably re-installed Ubuntu 13.04 ten times slightly different ways. I finally found how to skip the language packs, so at least that sped things up! :) This starts from the ubuntu-13.04-desktop-amd64.iso and UNetbootin as suggested on the official instructions for USB thumb drive creation from OSX. That part all works fine (booting the USB on the PC and trying Ubuntu and/or installing from there on the PC HD.) I have no CD drive on this PC, but I suppose I could get one. I would rather find some Linux install that works from USB like I've always done. After running boot-repair twice, in the ASUS BIOS I now see three different UEFI boot options in the priority list, and they are all labeled exactly the same: ubuntu (P6: WDC WD5000AAKX-00U6AA0) Then there's a non-UEFI option: P6: WDC WD5000AAKX-00U6AA0 (476940MB) And a fifth option appeared after the first boot-repair: Windows Boot Manager (P6: WDC WD5000AAKX-00U6AA0) I have tried all 5 of these, and I get exactly the same error. I have never had Windows installed on this HD. ASUS is calling it Windows Boot Manaer but I presume that's a mistaken label for whatever boot-repair did. I can boot on USB and run GParted and it looks great. The partitions all look normal. I found another case of this online with no solution posted. I can't find much about it online. Needs a Master Boot Record wipe/redo?? I'm not sure how.

• Instalar o Ubuntu / Install Ubuntu

  - by Joaquim Venâncio

  10:10 I installed Ubuntu alongside Windows 7, after the installation was able to upgrade to version 4.11. Now I'm trying to update to version 11.10 but I get an error message saying it is not possible to upgrade, I decided to install a partition that I created the part, but when I start the PC directly opens Windows 7 does not appear to me the option to choose which want to start the operating system. I formatted the partition where you had installed ubuntu, I've been looking for tutorials where you learn how to install ubuntu on a partition part to try to understand what my problem. I wonder if I can explain how to install ubuntu on a partition that part so that when I connect the PC to show me the option to choose which system I want to start.

• compiz problems - no effects work, despite the fact that they seem to be properly configured

  - by user97551

  I've looked through some posts about compiz and either haven't found the answer, or haven't understood what's been said. Could someone help me out? I installed ubuntu 12.04 through windows 7 (so I can dual boot) and installed compiz and set up the settings I want (hotcorners etc). For a while it seemed like it was going fine, but then I restarted the laptop, none of the compiz settings were working and the auto-launcher wasn't even coming up when I passed cursor over it. The computer is still usable, when I 'dash home' the auto-launcher appears, and I can tab through windows but yeh... the auto-launcher and hotcorners I set up through compiz aren't working at all. Any ideas? Oh, whilst I'm super grateful for any help I can get, I'd really appreciate it if you could keep any instructions as basic as possible. I'm a bit new at this... THANK YOU!

• New VHD for testing IE6 and IE7

  - by TATWORTH

  Regrettably old versions of IE (6 and 7)  are still in use and it is necessary to test against them. Microsoft recommended using a Virtual Machine to run these old versions.

• Disable new invisible border feature? (ruins compiz grid)

  - by Ike

  A new feature was added recently that adds an invisible border around the windows to grab for resizing (although i thought the new resize grip solved any big issues). This annoys me because it destroys the usefulness of the grid plugin of compiz.. i'm not sure if the border is part of compiz or gnome, but i'd like to know how to disable it. i couldn't find any options in ccsm or the window settings in gnome. See the screenshot to see how much waste is caused. These windows should match up instead of having blank space surrounding all of them.

• Netbeans styles. Are there style profiles similar to Notepad++?

  - by Djeman

  Not long ago I started to use Ubuntu. When I was on Windows I used Notepad++. I was very surprised when I found that Notepad++ is only for Windows. So I installed Netbeans. Netbeans is a powerful IDE and in general I like it, except default styles. Maybe are there style profiles (i.e. plugins or other forms)? It would be good if there is a style profile completely identical to Notepad++. I will be very thankful if you would help me to find what I'm looking for.

• Chrome window freezes in Ubuntu

  - by Dragon5689

  Sometimes, especially when I open pages that have some kind of multimedia contents, Chrome freezes. It always happens directly after opening a new tab. In contrast to the way Chrome usually has only tabs crashing, the entire windows freezes. If I have multiple separate Chrome windows open, the others keep working. I run Ubuntu 12.04 and Chrome in version 20.0.1132.47 but this has been going on since I last set up my machine around half a year ago. Anyone having the same problems or an idea what could be wrong here?

• Why do password strength requirements exist? [migrated]

  - by Bozho

  Password strength is now everything, and they force you to come up with passwords with digits, special characters, upper-case letters and whatnot. Apart from being a usability nightmare (even I as a developer hate it when a website requires a complex password), what are the actual benefits of having strong passwords (for website authentication)? Here are the prerequisites of a system that handles authentication properly: store passwords using bcrypt (or at least use salt+hash) - hard-to-impossible to find the original password when an attacker gets the database lock subsequent password attempts with a growing cooldown - no brute-force via the site

• Installed Ubuntu 14.04. How do I get it working with my new AMD R9 280X. When I run it I get garbage on the display

  - by user289455

  I installed Ubuntu 14.04 on my Gigabyte A88X FM2+ motherboard and A10 7700K processor. Everything worked perfectly. This system is dual booted with Windows 8.1 for gaming and I installed subsequently I installed an AMD r9 280X gpu. Windows was easy. It kept working with the new card installed and I just needed to download and instal the driver. Reboot and it's done. Ubuntu boots into a blank display. I enter the password and can log in. The menu on the left and bar at the top are visible but when I try to open an app, I get blocks and rubbish on the display. My preference is not to remove the card. So, my question is: What would be the procedure I could follow where I can log in using a text based terminal and download and install the AMD drivers.

La décision est claire et a été répétée à plusieurs reprise par Nokia. Cette décision, qui fait suite au choix startégique du finlandais de prendre Windows Phone 7 comme plateforme de référence pour ses futurs smartphones pose de très nombreuses questions sur l'avenir du framework (utilisé par MeeGo, Symbian mais aussi le bureau KDE, etc.).
