• How can I my video card work on Ubuntu 12.04?

  - by Cyriak Burton

  I've recently installed Ubuntu 12.04 on my desktop computer. In order to install Ubuntu, I had to unplug my video card because It was giving me problems, didn't allow me to install Ubuntu. So I unplug it, installed Ubuntu anyway, everything worked as charm, but now and I need to plug it again, but it doesn't work. Here some photos of the problem: Screenshot of the problem #1 Screenshot of the problem #2 Appear that screen and nothing else... I didn't install any driver (I'm kinda noob), in Windows 7 all worked fine, so the problem is with Ubuntu, compatibility problem I guess. Video Card: Zotac GeForce GT 240 O.S.: Ubuntu 12.04 (w/GNOME 3.2) Memory: 2 Gb HDD: 110 Gb Processor: Intel Pentium D 2.80 Ghz PLEASE HELP!!!

• How are hybrid VB6/.Net applications functioning in the Real World?

  - by Dabblernl

  I am maintaining a VB6 application and we are studying how to migrate to .Net We are considering doing this gradually by implementing new features in COM visible .Net classes and migrating existing functionality slowly. I found some instructive 'Hello World' examples about how to do this and it works fine with our App. But how is the real world behaviour of these hybrid applications? Are they stable, maintainable? Particular of our program is that more users on the same computer will use it by switching user accounts. EDIT: The VB6 app reads data from a USB connection and stores it in an Access database. The user can call up various views on the data. The data is cached in a hardware device, so interuptions in the reading of it are not fatal.

• understanding computers [closed]

  - by Ashwin

  Possible Duplicate: Good resources to understand how a program interacts with machine hardware I don't know if this is the correct StackExchange site to ask this question. But I could not find any other. I want to understand how a computer works from the software level to the internal structure. For example what happens when I press a button on keyboard. The OS interprets it and then what changes happen in the flip-flops. How is an operating system written? If it is written using some programming language, then how is that interpreter written. At some point it has to come down to the hardware, right? I know to program in c, c++ and java. But after all these years I am still not sure about what is happening inside. I would be grateful to anyone who points me to to a link or a video that explains this to the deep.

• JavaOne 2012 demo of Java SE Embedded on Raspberry Pi

  - by hinkmond

  Here's the Inquirer's article about our Java SE Embedded demos at JavaOne 2012 this year. Simon Ritter had a fun presentation showing the cool demo on the Raspberry Pi at his talk. See: Demo Java SE Embedded on Raspberry Pi Here's a quote: Oracle demonstrated Java SE for embedded devices running on the Raspberry Pi bare bones computer at the Java One show on Wednesday, with the aim of encouraging developers to try it out for themselves to create reference libraries for the target school children audience. I had the presentation after Simon and saw the size crowd he had. They were laughing and clapping at the demo and having a good ol' time. Good to see the interest in Java SE Embedded, even if it is for a "toy" device like the Raspberry Pi. Hinkmond

• How can a script detect if the user is idle

  - by josinalvo

  I want to check, inside a bash script (*), how much time the user of a X session has been idle The user himself does not have to be using bash, but just X. If the user just moved the mouse, for example, a good answer would be "idle for 0 seconds". If he has not touched the computer in 5 minutes, a good answer would be "idle for 300 seconds" The reason to not use xautolock straight away is to be able to implement some complex behavior. For example, if the user is idle for 10 minutes, try to suspend, if he is idle for more 5 minutes, shutoff (I know it sounds odd, but suspend does not always work here ...) (*)or could be another language.

• How to remove username from "Me" menu (right near to power button on the top panel)? [closed]

  - by Ivan

  Possible Duplicate: How do I replace the MeMenu username with my actual name? My user name takes approximately as long as would 6 icons. I don't need to see my username, I am the only user of my computer. How can I remove it? I use Ubuntu 10.10. UPDATE: The answer found: gconftool -s /system/indicator/me/display --type int 0 UPDATE: Unfortunately the solution doesn't work any more. Now it totally removes the instant messaging menu (including the icon) instead of just removing a name.

• Crash on shutdown when using second monitor

  - by plua

  I have recently added a second monitor to my setup. Instead of one VGA monitor, I now have one VGA and one DVI monitor hooked up to the computer. The displays work just fine. However, ever since this monitor was added Ubuntu (10.10) does not shut down properly. I go to shutdown and it starts shutting down but just hangs and I need to manually shut it down. This has been like this for weeks and I feel not comfortable shutting it down this way over and over again. Has anybody any idea what this can be? Or, also useful, does anybody know how to get some info on why this crash occurs? Any logs that can be used for this? Thanks! Paul

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• HP Pavillion laptop screen problems

  - by Liealais Vards Nekas

  Approximately after 4 days when I installed my Ubuntu 10.10 an interesting problem with my laptop screen starts. I had similar problem what you can see in this video - http://www.youtube.com/watch?v=jCYVfGVGWyY&feature=related - but it doesn't happen all the time. The most interesting thing is that, than I had that problem only when I turn my laptop screen in different angle. And this "bad" angle changes by the time, so after about 15 minutes after booting computer I can turn laptop screen in normal position. This is software or hardware problem? I'm using HP Pavillion dv9000.

• Need a few reboots to connect to wireless

  - by Debajyoti Nandi

  I am running xubuntu 12.10 on my msi wind U100 netbook. I have a problem with the wireless connection. Whether the wireless connects automatically to a known wifi hotspot (both at home and starbucks) is temperamental. Sometimes I need to reboot one or more times to get it connected. Otherwise, it tries and keep asking me to enter the password (which is saved and when it works it does, so the problem is not with the password). Every time my computer awakes up from sleep the same problem. I have to do a reboot to connect to wireless. I searched everywhere but found no solution. I would greatly appreciate if someone has any solution. I will gladly share the hardware/software or config info, if asked, but I don't know exactly what to share and where to find them. Thanks you for any help.

• When failure is a feature

  Warning: this post is going to be slightly off-topic and non-technical. Well, not computer science technical at least. I was reading an article in SciAm this morning about the possibility of a robot uprising. Dont laugh yet, this is a very real, if still quite remote possibility. The main idea that was described was that AI could rise one day to self-awareness and to an ability to improve itself through self-replication beyond human abilities to control it. Sure, thats one possibility, and some...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

• LibreOffice prints everything half size

  - by oldmankit

  Ever since I printed a document from Evince in landscape orientation, LibreOffice Calc / Writer refuses to print anything correctly. It is scaling everything by 0.5x and rotating it. To get the same effect, go to print - page layout tab - pages per sheet = 2. However, I don't want 2. I want 1. I have wizzed through all of the printing options a few times but can't get to the bottom of this. I've restarted my printer and computer several times. I have done sudo apt-get purge libreoffice* and reinstalled again. Still it will not print full size. (Of course I have checked that the page settings are set to A4 and portrait.) Update: this problem is specific to one printer only, to printing from within LibreOffice (Calc, Writer). With other printers / programs I have no problems.

• Wireless not functional

  - by Michael Berkenblit

  I am a complete newcomer to Ubuntu. Today I installed Ubuntu 12.04 onto an 3 or 4 year old laptop - an HP DV2221. Install went fine, except that I can't get the wireless card to operate. I see that there are drivers installed (Broadcom STA wireless) and it says they are activated, but the wireless light on the body of the computer is lit as orange, when it should be blue, and if I disconnect the Ethernet wire, there is no ability to get onto Firefox. I've looked at some of the similar questions on this site, as well as Googling the issue - mostly, I guess I don't understand how to navigate or do some of the fixes recommended - I'm fairly adept technologically around Windows, but know zilch about Linux and how to perform some of the fixes - so, if possible, please tell me how I get to the menus needed to rectify the situation.

• iTunes 7 can't find iPod in PlayOnLinux using Ubuntu 12.04 Precise?

  - by Endia

  I'm using 12.04 and the latest version of PlayOnLinux to run iTunes 7. I have my iPod 4th gen plugged in and the computer recognizes that it's mounted but it's not showing up in iTunes for me to do anything with it. I know there have been a lot of issues with being able to access your iDevices in iTunes from Linux when you're using a compatibility layer like PlayOnLinux or Wine (both of which I have), so it's recommended that I use Rhythmbox to back up my music etc. Which is fine, because that's part of what I need to do, but my primary need in trying to access my iPod in iTunes is that I need to remove my backup password so that I can jailbreak my iPod with the new Absinthe jailbreak. If there is some other way I can do this without iTunes you know of, I'd love to hear it. If not, what can I do?

• ASUS EeePC Fn+F2 ruins wireless until restart

  - by dawmail333

  I managed to get my wireless working beautifully (ath5k driver working great), and it works over a disable/enable wireless cycle, even a suspend/wakeup cycle (read some people have issues with that). Unfortunately, I discovered that if I press Fn+F2 on my keyboard (Asus EeePC 900HA, so that's the wireless toggle key), wireless then stops working until I restart the computer. How can I fix this? I'm running UNR 10.10 (with Unity turned off tyvm!). I heard something about Jupiter controlling these keys, but what about asus-laptop? How can I fix this behaviour? TIA. (Note, I'm a power user, but still fairly new to Linux. I'm picking up speed though).

• I can not install Ubuntu 14.04 due to some problem?

  - by user285643

  I have installed Window 8.1 on my HP laptop.Now I want to install Ubuntu 14.04,I try to use "Wubi" but when I use it, after installation on window, when my computer restart i have a message "No root file system is defined" I have read some thread here and i got some solution. One of them are "I must format my partition again, using ext4 format and mount on it". I did it by using Gparted in Try Ubuntu mode, but I got another message "/dev/sda contains GPT signatures,indicating that it has a GPT table. However, it does not have a valid fake msdos partition table,as it should. Perhaps it was corrupted--possibly by a program that does not understand GPT partition table. Or perhaps you deleted the GPT table, and are now using msdos partition table. Is this a GPT partition table?"

• Putting Ubuntu Server on to a networked HDD

  - by SimplySimon

  Firstly, I know very little about servers and secondly the 1Tb HDD I have has network capabilities, but no software is installed on it, so when connected to the computer it is seen as a network connection, but not as a drive. Any advice on how to get started would be great. Up until now, I have been using it as a USB drive which worked well, but when this is sorted, I would like it to be connected directly to our BT HomeHub accessible through the WiFi for all the family to use as a film and back up repository. I would then be able to set up individual accounts for each family member to use and may be, if possible, make it accessible from outside locations. The First question then is: How can I install Ubuntu server on the 1Tb HDD attached directly to the computers network port but which doesn't show up in Nautilus?

• Can I use GNOME-applets in Unity?

  - by Moma Antero

  Hello, Applets are small programs that you attach and start from the GNOME's toolbar. See picture: http://www.futuredesktop.com/audio-recorder/recorder-applet.ogv My favourite applets are: rec-applet: Smart audio recorder applet. You can get this from Launchpad. clipart-finder: Find and download clipart to your computer. You can get this from the Launchpad. 1) Can I use these applets in UNITY as is? 2) What changes I have to make to applets' code (rec-applet and clipart-finder) to make them usable in Unity? 3) Where is the applet-specification for Unity?

• Running an Application on a Different Domain

  - by Mark Flory

  Were I am contracting at right now has a new development domain.  Because of IT security rules it is fairly isolated from the domain my computer normally logs into (for e-mail and such).  I do use a VM to log directly into the domain but one of my co-workers found this command to run things on your box but in the other domain.  Pretty cool. For example this runs SQL Server Management Tool for SQL Server 2008: runas /netonly /user:{domain}\{username} "C:\Program Files\Microsoft SQL Server\100\Tools\Binn\VSShell\Common7\IDE\ssms.exe" And this runs visual studios: runas /netonly /user:{domain}\{username} "C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe" It does not solve the problem I wanted to solve which would be to be able to assign Users/Groups in Team Explorer.  It instead still uses the domain I am logged into's groups.

• BURG broken by Windows

  - by Sallée

  I have successfully installed, using Super Boot Manager, BURG in a computer at my work. After I boot into Windows XP, BURG is no longer operational. The machine just boots to the BIOS screen, goes black, and then boots to the BIOS screen again ad infinitum. The only way to recover I have found so far is to use a Boot-Repair USB, which restores either GRUB2 or MBR, not BURG. Everything works fine under GRUB2, but I prefer the improved look of BURG to make things easier on my students.

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?

• Windows 7 won't boot? Tried Boot Repair (dual-boot)

  - by user206870

  I downloaded Ubuntu and installed it so that my computer was dual boot. The first day, Ubuntu and Windows both worked great. Unfortunately, the next day, after messing around on Compiz Config Settings Manager to get the rotation cube, I tried booting into windows 7, and it wouldn't boot. It just goes to the screen where the Windows logo comes up and says Windows 7, and then reboots without even displaying an error message. I tried boot repair and it didn't work, the problem's still there. How can I fix this? PS: here's the link that boot repair gave to me: http://paste.ubuntu.com/6287090
