• Why doesn't my Nvidia driver support 1280*1024?

  - by Alvar

  EDIT: I think the problem is in the NVIDIA x server, that doesn't support an RGB screen from 1990. The screen was the best of them all when it was released. This a strange thing! In windows the EDID must work because 1280*1024 is used as max resolution, but in ubuntu those stuff aren't being received, so how do I tell ubuntu/nivida to find those EDID stuff? Hi, I have an external monitor which is an 20" 1280*1024. In windows 7 it works fine with that resolution but in ubuntu it can't. The screens model name is IntelliColor Display/20 and the name of the company is "radius".recived Well, twin view is working but the only maximum resolution is 1024*768. I'm using nividas x server program. If I force it to use 1280*1024 it all crashes and I have to force a reboot. alvar@alvars-laptop:~$ disper -l display DFP-0: HSD121PHW1 resolutions: 320x175, 320x200, 360x200, 320x240, 400x300, 416x312, 512x384, 640x350, 576x432, 640x400, 680x384, 720x400, 640x480, 720x450, 640x512, 700x525, 800x512, 840x525, 800x600, 960x540, 832x624, 1024x768, 1366x768 display CRT-0: CRT-0 resolutions: 320x240, 400x300, 512x384, 680x384, 640x480, 800x600, 1024x768, 1152x864, 1360x768

• Cannot boot: FGLRX 8.780 + Kernel 2.6.35-25

  - by pluc

  The situation before this all happened is pretty standard. I have a HP Pavillion dv5 laptop with an ATI Mobility Radeon 4200 series. It always worked fine with Ubuntu for as long as I can remember. However, at one point, something happened and truly made a majestic mess of things. It might've been extra repos I enabled with Ubuntu Tweak - I do not know. But something made it so that my system would not boot any longer. And when I say "won't boot", this is what I mean: - Durning a normal bootup, any entries (except Windows) selected with GRUB (or BURG, not even sure which one I'm using anymore) will spawn the Ubuntu loading screen - then try to start X (or GDM) 5 times. The screen goes to dark, black and back to the Ubuntu loading screen. Then it just stays there until I spawn another TTY. I have no idea what is happening or why. There are no errors in my logs, and I'm truly at a loss here. I've linked three files: Xorg.0.log, the output of dmesg and the GDM log: Xorg.0.log: http://ubuntu.pastebin.com/tpVKc2tc dmesg: ubuntu.pastebin.com/Nd5aYj45 gdm's :0.log: couldn't post due to lack of points :( Let me know if any of you more knowledgeable folks can restore some sanity in my life. Any help is greatly apreciated.

• Can't install on a Thinkpad W700ds

  - by Habstinat

  I want to install Ubuntu on my computer. I don't know much about Linux, but I know my way around a terminal and whatnot. My computer, a ThinkPad W700ds, refuses to read from my CD when booting. The md5sum is correct and the same CD boots fine from another computer. When I try to install from a USB, I can get the main screen, but when I select any of the options from there my screen turns black for more than 3 hours until I have to turn it off. Is there anything I can do about this? I want to have a true partition, don't want a Wubi'd install. It's a 10.10 x64 image, but my computer is 64 bit (running Windows 7 x64 right now) and the exact same CD is bootable on other computers. I've been on #ubuntu IRC for days trying to work this out but nobody knew, so I figured I would get more responses by posting to here. UPDATE: Thanks Jorge Castro. Both the alternate and desktop installers seem to not work at all with the CD. On a USB, the alternate installer lets me start installing, but in the middle of installation I get this message. The people on #ubuntu told me to just exit installation at that point, so I did.

• Samba share external USB device

  - by bioShark

  I managed to share stuff from my Ubuntu 12.04 to my private network, and the data is visible from a Windows machine. I even shared a hdd that has windows on it. So everything seems to work fine. When I want to share a mounted device (USB pen drive, USB HDD... etc) however, I get from the Windows machine: Access denied on file \... I realize that this is due to the missing rights on the mounted folder. By default a mounted folder gets the equivalent of 700 : drwx------, and the owner myself. But, I can't seem to change the rights on the external device... they remain 700. Is there a special trick I need to do in order to share NTFS mounted usb devices? Thanks P.S. from this Question I see that NTFS devices can not be shared....is this true? It's a bit strange, because I have in my PC 2 HDD's with 3 NTFS partitions, and I can share them without a problem.

• Why blogger puts BR tags only when content served via RSS feed?

  - by tamashumi

  I have a problem with using my new blog RSS feed. I wrote a post (the first one) with some code examples formatted by SyntaxHighlighter. To paste a code sample I'm switching from WYSIWYG to HTML view and put the code inside pre tag like this (don't worry, h4 tag was opened a line above the screenshot area): The problem is that such pre tag, when later accessed via RSS feed contains br tags instead of new line characters. Below is screenshot of the adequate RSS source code: What's most important when accessed via www, the post html is formatted fine, no brs inside pre. I verified that by downloading the blog post with wget. So I believe this isn't SyntaxHighlighter issue nor any 'new line' formatting on blog post save. This is a real problem as I want aggregate my blog on employers blog and all formatting of code examples is broken because of that. The base question is: how to get rid of those unwanted brs served via RSS? What's strangest friend of mine also uses blogger for such aggregation and he has no such issue. I checked his RSS feed and there are no brs inside pre tags. We also compared settings of our blogs. However we have found no clue. The blog post RSS for the blog (just check source and search for string: pre class="brush) Mentioned friend's blog Last thing: I see content served from RSS is now also html encoded. If I remember well, it wasn't previously.

• PS2 Eyetoy Recording Quality

  - by Fire

  I have Ubuntu 12.04 LTS and a PS2 eyetoy "Namtai". Don't worry - this is not the sterotypical " how do I get my eyetoy working" question. My eyetoy works fine on Cheese, gucview and various other media software like VLC. However, It seems like I am capped by 25fps. If I recall, the eyetoy is much better than this (~60fps) but cannot find any way to fix this. The best program that I have have found is VLC because its advanced options allow you to change many settings but the framerate setting appears to have no effect. What software or settings can I use to take full advantage of my eyetoy? To give you the full information I wish to attach multiple eyetoys to the system and record from all of them. (Security software like motion and zoneminder, I couldn't get installed correctly on my system- so I haven't tried those yet). edit - I tried the same camera on a Windows system and the frame rate is much better in VLC compared to the Ubuntu system. Mind you with default settings in Windows VLC, the resolution isn't great. However, in Skype for example the resolution is amazing and the framerate is good. It seems there must be some settings I am missing somewhere because it doesn't appear to be a hardware problem...

• No text in working indicator-messages after enabling different icons depending on the status

  - by user106750

  My indicator-messages has some problems. As you can see in the image, there appears no text. The indicator is working correctly, if there is some income, a number will appear in its proper place or I will be able to see the minutes passed after I got an email, but still no information. As you can see in the picture, I changed the envelope icon for the status one. I configured it as is indicated in http://www.omgubuntu.co.uk/2012/08/ubuntu-add-new-message-indicator-icons, with the indicator changing depending on the status. But I modified it so I see the bubble. The bubble gets the arrow when I'm absent, for example, or an "X" of I'm disconnected, and also turns blue if there an income. I believe the problem is related with this new indicator. The first days, it was working fine, but then the text dissapeared. I've tried uninstalling and reinstalling the packet, with no success. I'm using ubuntu 12.10 64bits with Unity. Someone has an idea how to fix this? I would prefer conserving the characteristic of having different icons. Thanks a lot!!!

• Audio not working in 12.10

  - by frampy

  I did a clean install of 12.10, when I open Sound Settings in gnome the only device in the list is "Dummy Output", and sound is not working. Sound worked fine out of the box in 12.04 I ran alsamixer, it says my card is "HDA Intel", and chip is "Realtek ALC880". The alsamixer playback output was set to mute at first, unmuting did not fix. I checked out the info at http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ as suggested on a similar question, I've done everything there except installing the ubuntu audio dev team driver. Should I try install this? Edit: I've been reading the sound troubleshooting guide at https://help.ubuntu.com/community/SoundTroubleshooting It looks like Ubuntu is finding my audio device correctly. mike@wucade:~$ lspci -v | grep -A7 -i "audio" 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) Subsystem: Albatron Corp.

• How come I cannot make this file executable (chmod permissions)?

  - by bappi48

  I downloaded Android Development Tool for linux (ADT) and placed it in home directory. After unzipping the files, when I double click the "eclipse" executable file; the eclipse works perfectly fine. But If I unzip the ADT in a different directory, in my case directory E: (is shown when I boot in windows 7) There double clicking the same "eclipse" executable file does not run eclipse. It shows error message: Could not display /media/Software/00.AndroidLinux/ADT/eclipse/eclipse. There is no application installed for executable files. Do you want to search for an application to open this file? If I press yes in the Dialog, it finds "Pypar2" which is not my solution. I found that the "eclipse" file permission is following -rw------- 1 tanvir tanvir 63050 Feb 4 19:05 eclipse I tried to change the permission by "chmod +x eclipse" , but no use. This command does not change the file permission at all in this case. what should I do?

• Farseer circle hangs where it's spawned

  - by necrosmash

  I'm currently trying to simply spawn a circle in Farseer. However, it's stuck wherever I spawn it! The game is updating fine, as I can see the circle spinning in place when I spawn it because of how I currently have gravity set up (following code from Game1.cs): // Initialise the screen center for use with // the Level class screenCenter = new Vector2(graphics.GraphicsDevice.Viewport.Width / 2f, graphics.GraphicsDevice.Viewport.Height / 2f); world = new World(new Vector2(20, 20)); currentLevel = new Level1(screenCenter, circleSprite, groundSprite, ref world); Level1 constructor: public Level1(Vector2 screenCenter, Texture2D circleSprite, Texture2D groundSprite, ref World world) { player = new Player(ref world, screenCenter, circleSprite); ground = new Ground(ref world, screenCenter, groundSprite); listLevelItems = new List<LevelItem>(); listLevelItems.Add(player); listLevelItems.Add(ground); } Player constructor: public Player(ref World world, Vector2 screenCenter, Texture2D sprite) { setSprite(sprite); setPosition((screenCenter / MeterInPixels) + new Vector2(0f, 0f)); playerBody = BodyFactory.CreateCircle(world, 96f / (2f * MeterInPixels), 1f, playerPosition); getBody().BodyType = BodyType.Dynamic; // Ball bounce and friction getBody().Restitution = 0.3f; getBody().Friction = 0.5f; } If I use a breakpoint and change the playerBody position while the game is halted, the ball does move, but stays fixed in its new location. Any help would be greatly appreciated.

• What to do about "system running in low-graphics mode"?

  - by ubuntubabe

  My Dell which was 5 years old suddenly karked it and I had the "low graphics" black screen and useless dialogue box. As I believed it was a dead graphics card I went out and bought a brand new machine. I put aside the new machine and tried again in vain to open the Dell. I eventually got to the command line via Ctrl+Alt+F1. I logged into my account from there, and simply started a series of sudo apt-get remove of various softwares that I knew were installed on my PC (software without any great consequence like Google earth, tweak, Skype etc). Lo and behold after a sudo reboot my computer was fine again! So now I have 2 computers. BUT one week after buying the other one and installing 12.04 because I love Ubuntu, the SAME PROBLEM arrived! I once again deleted Google earth, Skype, and did a sudo reboot and everything worked as before. I think there is a bug or something in 12.04 as this problem has never arisen with any other versions of Ubuntu.

• JavaOne 2012 in Review

  - by Janice J. Heiss

  Noted freelance writer Steve Meloan has a new article up on otn/java, titled, “JavaOne 2012 Review: Make the Future Java” in which he summarizes the happenings at JavaOne 2012. Along the way, he reminds us that if the future turns out to be anything like the past, Java will do fine: The repeated theme for this year's conference was ‘Make the Future Java,’ and according to recent stats, the groundwork is already firmly in place:    There are 9 million Java developers worldwide.    Three billion devices run Java.    Five billion Java Cards are in use.    One hundred percent of Blu-ray Disc players ship with Java.    Ninety-seven percent of enterprise desktops run Java.    Eighty-nine percent of PC desktops run Java.This year's content curriculum program was organized under seven technical tracks:    Core Java Platform    Development Tools and Techniques    Emerging Languages on the JVM    Enterprise Service Architectures and the Cloud    Java EE Web Profile and Platform Technologies    Java ME, Java Card, Embedded, and Devices    JavaFX and Rich User Experiences”Meloan artfully reminds us of how JavaOne makes learning fun.

• MVC and delegation

  - by timjver

  I am a beginning iOS programmer and use the Model-View-Controller model as a design pattern: my model doesn't know anything about my view (in order to make it compatible with any view), my view doesn't know anything about my model so they interact via my controller. A very usual way for a view to interact with the controller is through delegation: when the user interacts with the app, my view will notify my controller, which can call some methods of my model and update my view, if necessary. However, would it make sense to also make my controller the delegate of my model? I'm not convinced this is the way to go. It could be handy for my model to notify my controller of some process being finished, for example, or to ask for extra input of the user if it doesn't have enough information to complete the task. The downside of this, though, is that my controller would be the delegate for both my controller and my model, so there wouldn't be really a proper way to notify my model of changes in my view, and vice versa. (correct me if I'm wrong.) Conclusion: I don't really think it's a good idea to to have my controller to be the delegate of my model, but just being the delegate of my view would be fine. Is this the way most MVC models handle? Or is there a way to have the controller be the delegate of both the controller and the model, with proper communication between them? Like I said, I'm a beginner, so I want to do such stuff the right way immediately, rather than spending loads of hours on models that won't work anyway. :)

• SharePoint 2007 Enabling Incoming Email Error

  - by Cherie Riesberg

  Symptom: When configuring incoming e-mail, the e-mails come through just fine if the server name is in the e-mail address: [email protected] but when you change it to a vanity name [email protected], the message is bounced back and you get this error: Delivery has failed to these recipients or distribution lists: [email protected] Your message wasn't delivered because of security policies. Microsoft Exchange will not try to redeliver this  message for you.    Please provide the following diagnostic text to your system administrator. The following organization rejected your message: servername01.fqdn.com.   Problem: The SharePoint server relay rejects the message because it doesn't recognize the name.  You have set it up in Exchange, but you need to set up an alias in the SMTP service on the SharePoint server;   Solution: Configure an Alias Domain An alias domain is an alias of the default domain. You can set up alias domains that use the same settings as the default domain. Messages that are received by the SMTP Service for an alias domain are placed in the Drop folder that is designated for the default domain. To configure an alias domain, follow these steps: Start IIS Manager or open the IIS snap-in. Expand Server_name, where Server_name is the name of the server, and then expand the SMTP virtual server that you want (for example, Default SMTP Virtual Server). Right-click Domains, point to New, and then click Domain. The New SMTP Domain Wizard starts. Click Alias, and then click Next. Type a name for the alias domain in the Name box, and then click Finish. Quit IIS Manager or close the IIS snap-in.

• Extremely slow desktop and laggy. Need help with graphics driver

  - by user171624

  I am a fresh newbie Ubuntu user and I just installed my first Ubuntu 13.04 onto my HP Slate 2. I did a liveCD on my USB drive and installed everything perfectly fine...nice and smooth, not a trace of lag. Then I rebooted using Ubuntu itself on the computer, it was extremely slow and laggy. Icons or any buttons doesn't trigger right away, the performance of the entire thing looks like either 0.25 fps to 1 fps. My HP Slate 2 information: Processor: Intel Atom Z670 1.5Ghz Memory Ram: 2.0 GB Videocard: Intel GMA 600 (PowerVr SGX535) SolidStateDrive(SSD): 32GB I tried installing the intel linux graphics driver and it failed to install because it said I don't have any intel based graphics card. Well...I do as you see above. What can I do? I can't get on the internet on it, I'm using my primary computer (Windows 7) to do all the searchings and put the files onto the USB to move it over to my tablet. Simply...I don't get it...using liveCD on USB, it was all nice and smooth...then after the installation...BOOM! Slow, laggy, and etc. Can anyone help me? Thanks!

• Trouble with collision detection in XNA?

  - by Lewis Wilcock

  I'm trying to loop through an list of enemies (enemyList) and then any that have intersected the rectangle belonging to the box object (Which doesn't move), declare there IsAlive bool as false. Then another part of the code removes any enemies that have the IsAlive bool as false. The problem im having is getting access to the variable that holds the Rectangle (named boundingBox) of the enemy. When this is in a foreach loop it works fine, as the enemy class is declared within the foreach. However, there are issues in using the foreach as it removes more than one of the enemies at once (Usually at positions 0 and 2, 1 and 3, etc...). I was wondering the best way to declare the enemy class, without it actually creating new instances of the class? Heres the code I currently have: if (keyboardState.IsKeyDown(Keys.Q) && oldKeyState.IsKeyUp(Keys.Q)) { enemyList.Add(new enemy(textureList.ElementAt(randText), new Vector2(250, 250), graphics)); } //foreach (enemy enemy in enemyList) //{ for (int i = 0; i < enemyList.Count; i++) { if (***enemy.boundingBox***.Intersects(theDefence.boxRectangle)) { enemyList[i].IsDead = true; i++; } } //} for(int j = enemyList.Count - 1; j >= 0; j--) { if(enemyList[j].IsDead) enemyList.RemoveAt(j); } (The enemy.boundingBox is the variables I can't get access too). This is a complete copy of the code (Zipped) If it helps: https://www.dropbox.com/s/ih52k4e21g98j3k/Collision%20tests.rar I managed to find the issue. Changed enemy.boundingBox to enemyList[i].boundingBox. Collision works now! Thanks for any help!

• Mirroring of Apps across servers

  - by user1038814

  We wish to host multiple apps across multiple servers. What we are looking for (ideally) is an existing solution which will work. For example, normally to do it we'd follow a route (for failover) like: App is installed on one server along with mysql database App is also installed on a second server. Rsync is used to mirror the files over to the second server and ensure consistency MySQL is installed with a Master-Slave setup. We use a service such as DNS Made Easy which has a DNS failover. If one server goes down it automatically routes traffic to the backup server We have done the above a few times and generally its fine. The issue I have here is that the above is for one app. What I would like to look at is how we can manage for multiple apps and if there is a layer (such as VMWare) that has complete mirroring built in at the OS level? For example how do web hosts currently do it when they ensure that more than one machine is running a bunch of hosted websites. If you were running hosting and you had 200 clients on a server you would want the same clients across 2 or more servers and want everything mirrored. Any advice would be much appreciated.

• Windows 7 – Fun with VHD

  - by guybarrette

  I’m teaching about TFS 2008 next week and I wanted to use TFS in a virtualized environment so I downloaded the TFS + Team Suite VPC image from Microsoft’s Website.  Working with Windows 7, I opened the VM with the built-in Windows Virtual PC.  The VM loads fine but the problems started when I tried to install the VM additions: I simply couldn’t get them to install properly. I then looked at VMware and found that they have a product called VMware Player that can load Virtual PC VMs.  Tried that but VMware Player failed in converting the VHD. I then looked at VirtualBox.  Created a new VM, attached the VHD and bingo!  Worked like a charm.  The only real caveat is that the guest Windows will ask for the OS CDs to install new drivers so you must have either the CD/DVD or the ISO file (sweet!) to proceed. OK, I got it working in VirtualBox but I’m curious why I couldn’t install the additions from Windows 7 Virtual PC onto a Windows Server 2003 VM.  Anyone has a clue? BTW, thanks to Rolly Perreaux who pointed my to his blog where he goes into great details explaining how to use VM images with VirtualBox.  Good stuff! var addthis_pub="guybarrette";

• Is there a PROPRIETARY driver (NVIDIA or ATI) that actually works with 12.10?

  - by DS13

  NOTE: I see many similar topics on this, but I've tried all their suggestions, and nothing has worked. THE MAIN DIFFERENCE SEEMS TO BE: I always get a black screen with a blinking cursor, while others seem to get through the boot-up and see distorted graphics or just their wallpaper. ISSUE: I do a clean install of Ubuntu 12.10. Boots fine with the “nouveau” graphics driver – graphics (even just menus) are very slow, choppy, and distorted. The three other driver options in Ubuntu (official NVIDIA drivers), all result in a variation of the black screen on boot up. There will be NO access to a command line/GUI in anyway what-so-ever (tried every option recommended out there, but the system is unusable at this stage). I can only reinstall, and try different drivers…and I only ever get one shot at it. QUESTIONS: -Does anyone know of a PROPRIETARY driver that will actually work on 12.10 with a NVIDIA or ATI card? -Should I just buy a newer graphics card to put in as a replacement? MORE INFO: This is my second computer, and I’m just trying to get a working install of Ubuntu on it. I don’t want to put much money into it, as I have seen Ubuntu run great on much older/less capable machines. I’ve got a decent'ish Core2Duo Intel processor (2.13Ghz), 2GB of RAM, 320GB hard drive, 32-bit architecture, and there is no other O/S installed. It appears as if the graphics card (NVIDIA Geforce 7350 LE) is holding me back. TRIED SO FAR: -all drivers available in Ubuntu *all fail -manual install of some different NVIDIA drivers *all fail -also tried installing the generic kernel, Nvidia driver doesn't work in 12.10 *no difference -tried installing 12.04 *same results -every method suggested to at least get a command line after switching to a NVIDIA driver *all fail -UPDATE- Re-tried everything above with a new NVIDIA Geforce 210...same results for everything. -UPDATE #2- Re-tried everything above with a new AMD Radeon HD 6450...installed the proprietary driver from Ubuntu's "Software Sources" menu...EVERYTHING NOW WORKS. See "answer" below for summary.

• How to fix GRUB on dualboot with Windows7 and Ubuntu?

  - by b_oliv

  I am a relatively recent user of Linux. I had several releases of Ubuntu installed on my laptop working in dual-boot and never had any issues. Recently, I installed openSUSE because I thought it would be necessary for an assignment at my university. It turns out it wasn't so I returned to Ubuntu and decided to burn the new .iso to a CD and install it. The problem is that during installation process I almost for sure messed up with the partitions and now, whenever I tried to load Windows 7, it will tells me that a required device is inaccessible. So, I reinstalled Ubuntu again and now all I get is that I am redirected to the GRUB menu without any warnings. I tried creating a Windows Recovery Disk but it gives me Unexpected I/O error. I suspect it is because it was downloaded from the Internet and maybe some files weren't there. I tried everything without success, so I decided to ask here, in the hope I can receive some help and also learn how to help others with it in the future. Here it is my boot info summary: http://paste.ubuntu.com/1344990/ Also, I might add, that on the boot-repair advanced options, the box repair Windows boot files is "locked", so I can't check it. EDIT: Apparentely, the box is locked, because, from what I understood after reading the boot-repair information, everything is fine with my windows boot-files... I still need some guidance though

• Show and Tell: What work are you the most proud of? [closed]

  - by dannywartnaby

  Hey, In the spirit of building community, and because it's always cool to see great work being pushed out and created by people, anyone up for a little show and tell? The rules are really simple, and this is supposed to be a bit of fun, so; post a link to a single piece of work (anything you've produced, designed or developed (or helped developed)) and write a little paragraph or two on what it is, what you like about it, the technology you used and perhaps one thing that you learnt from the project. It could be a website, framework, open source project, game, mobile application... etc. So, allow me to start. I'm personally very proud of a tiny iPhone application I designed and developed. It's only available to UK AppStore users, and I only have a small userbase, but, I like it. The application is called Sushi Total: http://knowledgeisporridge.com/sushitotal.html It's written in Objective-C. It's a very simply application that allows you to total up your bill at Yo Sushi restaurants by tapping coloured plates. If I learnt anything from making this application it's this: I believe software should be simple and uncluttered, and that producing an application with one feature is absolutely fine as long as it works really well. So, who's next?

However... if I open it with the server running at least once (it will work) then I can open it later without problem. It looks like even though the page was cached in safari, it is not cached in this saved app. Anybody knows how to get around this? Thank you!

• Touchpad not working after connecting hdmi cable

  - by user286632

  I had installed Ubuntu 14.04 2 weeks back on my new laptop along side Windows 8. 1. And it was working fine. But yesterday after I connected Ubuntu with my TV using the HDMI cable, the cursor/ pointer stopped working. The pointer is not visible and my touchpad is not working. I connected the hdmi cable with youtube in Firefox. But only the wallpaper was visible on the TV. Also the right click menu, alt tab window, etc was also visible. But the side menu and the Firefox window was not visible. The pointer was visible on the tv and the touchpad was working, I was able to move the pointer. After I removed the HDMI cable, my cursor/pointer disappeared and my touchpad is not responding! ! I tried to restart many times, but still no luck. Its still not visible in the desktop. The pointer is visible in the login screen, but is not responding to the touchpad. I tried to login to my KDE session, there too the pointer is visible but is not responding to the touchpad. It is not moving.

• What's the benefit to learn Java programming?

  - by user30139

  I'm from the PHP world. Recently I'm trying to learn about Java. Because simply I'm a bit interested in Android development. Learning about Java gives more control about my cellphone. Say I could fine tune some applications to fit my personal requirements or even make my own ones. Still Java is a new world to me. I guess I'm already too comfortable with weak typed languages such as PHP. Honestly I think application development of no matter which kind wouldn't make too much difference. Because just as web development mostly framework based, what the developer do is to fill the blanks meaning to follow the protocols the given by the framework. Most of the code is still about business logic, that's what application development all about, right? The big difference seems to lie on the programming languages. Comparing to PHP, Java holds a whole package of constraints and practices. At this point, what are the benefits to learn programming in it?

• What version was installed? x64 or i686? What's the difference exactly?

  - by Seppo

  Okay, so heres my problem. I recently started migrating several services to individual VMs on my box, using VirtualBox 4.1. I created a new VirtualBox VM with guest type "Ubuntu (64 Bit)". I've already done this before and it worked like a charm. I then installed unbutu server (12.04) from the exact same dvd image. All the time I thought that it should have installed x64. I already put a few hours work into the new VM, migrating the webserver and mail system etc. Today I tried installing a x64 piece of software and it suddenly told me that it needed x64 and I had only i686. I checked uname -a and this is what it gave me: Linux hostname 3.2.0-29-generic-pae #46-Ubuntu SMP Fri Jul 27 17:25:43 UTC 2012 i686 i686 i386 GNU/Linux Any guesses what went wrong? All the time I was thinking I had a x64 system. Any way to move to a "real" x64? I have a second VM on this host which is running x64 just fine .. P.S.: grep --color=always -iw lm /proc/cpuinfo returns lm among the flags.
