• DockbarX Applet not loading

  - by Nik

  I used to have dockbarX applet installed on my gnome panel. However one day when I login in I got a error message which can be seen in the screenshot below. So I removed it, and then tried adding it again to the gnome panel but I still get the error message. I am running the latest version of dockbarX 0.43 with the helpers enabled and media buttons etc. I did not update it recently and have been using this version for a couple of weeks now and got this problem only now. How can I solve this problem?

• Sharepoint Expiration Policy not working

  - by spano

  I have a Sharepoint 2010 list with a custom content type with an associated retention policy. The policy consists of a custom formula and then the Send to Recycle Bin action. However, I realized that the items were not being deleted. I verified the list settings and the retention policy was configured: I run the Expiration Policy job several times but no items were deleted and no errors found in the logs. I also added logging to the custom formula but no logging was found neither. Finally, I found...(read more)

• Unity does not display properly [closed]

  - by Ben Isaacs

  Ubuntu Unity on the Ubuntu netbook edition installs without a problem but when I log in though, where the panels are, there is just blank area with a shadow effect style thing on it. I can open apps but the Window buttons and the global menu are not visable. Does this mean that I cannot use Unity. I'm running it through Wubi on a Dell Inspiron 1501 laptop. My total ammount of graphics memory is 831MB My dedicated memory is 128MB. The odd thing is is that Windows Aero displays without a problem so why is there a problem with Unity Hope this helps Ben

• USB Logitech Rumble Pad 2 gamepad AND Thustmaster Universal Challenge Wheel not working in wine

  - by Rick Gionfriddo

  The controller is detected by the OS, and shows up in lsusb, and I can configure it with jstest-gtk, but Live For Speed in Wine doesn't recognize it as connected. Using Lubuntu 12.04, wine version 1.5.5. P.S. - It worked on a previous install of regular Ubuntu 12.04, using the same Wine version. Have tried installing/overriding/un-overriding various DLL's through winetricks to no avail, including xact and dinput8. Since it worked in a previous install of the same version, I figured it was a configuration error, and that I should ask here as opposed to put in a bug report on winehq. EDIT: I just used both controllers in TORCS... why do they work in native games, but not in wine?

• combo microphone does not work on Natty.

  - by Senthil Kumaran

  I have a Internal Audio Hardware card and my Laptop (Lenevo IdeaPad) presents a single slot as a combo Microphone and headphone jack. On Windows, I attach my ipod headphone to jack and speak directly to my computer. I assume there is a microphone which is listening to my voice and I can communicate two-way. On Ubuntu, the microphone always seem to be listening to random noise. So any input by speaking to the computer is not possible. What could be the reason and how do I troubleshoot this?

• Memory management in Qt?

  - by Martin

  I'm quite new to Qt and am wondering on some basic stuff with memory management and the life of objects. When do I need to delete / destroy my objects? Is any of this handled automatically? In the example below, which of the objects I create do I need to delete? What happens to the instance variable myOtherClass when myClass is destroyed? What happens if I don't delete / destroy my objects at all, will that be a problem to memory? in MyClass.h: class MyClass { public: MyClass(); ~MyClass(); MyOtherClass *myOtherClass; }; in MyClass.cpp: MyClass::MyClass() { myOtherClass = new MyOtherClass(); MyOtherClass myOtherClass2; QString myString = "Hello"; } As you can see this is quite newbie-easy stuff but where can I learn about this in an easy way? Thanks really much

• 12.10 does not boot sometimes from the hard drive, but it does consistently from the CD

  - by Robert

  I have recently switched from Windows 7 to Ubuntu 12.10. I have installed Ubuntu 12.10 and I cleared everything from my computer, but it randomly stops at different screens. Only a purple screen comes up. I can choose Ubuntu from a list and a blinking white dot appears in the top left corner. The previous things happen and the Ubuntu login screen appears an I can log in. It is random. and I have not changed anything. I can always insert the bootable CD and it will work every time.

• Grub does not autoboot the default option after upgrade to 12.10

  - by Petr Kozelka

  I recently upgraded Ubuntu from 12.04 to 12.10 and since that time, the system does not automatically boot. It always opens the boot menu, and I have to press Enter to make it boot Ubuntu. It seems to be ignoring the timeout value, and using a 'neverending' timeout. There are no other systems (no dual boot), only the options originally installed by default Ubuntu 12.04 installation. My /etc/default/grub has only these effective options: GRUB_DEFAULT='Ubuntu' GRUB_HIDDEN_TIMEOUT=1 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=1 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" GRUB_TERMINAL=console I experimented with GRUB_DEFAULT, giving it values '0', '1', 'Ubuntu' but nothing helps. Yes I always run update-grub afterwards. How can I make the system booting again ?

• Entity Framework v4 examples and tutorials of conceptual model mapping

  - by Rody van Sambeek

  In an application I'm writing I have a fairly complicated Database model. I'd like to use EF4 to map this to a whole lot nicer conceptual model. However all the tutorials I've read are with samples of 2 or 3 tables which all map 1 on 1 to the conceptual model. I'd like to learn how to correctly map the database model to a different conceptual model using VS 2010. However I can't find any good tutorials or (preferabally) instruction video's. Somebody got any tips, links or even books?

• Bind multiple request parameters to one object in Spring 3

  - by Max

  Hi, I can't figure out a way to bind several arguments and headers to one request parameter using annotations in Spring 3. For example, let's say I'm getting this request: Headers: Content-type: text/plain; POST Body: Name: Max Now I want it all to mysteriously bind to this object: class NameInfo { String name; } Using some code like this: String getName() { if ("text/plain".equals(headers.get("content-type"))) { return body.get("name"); } else if ("xml".equals(headers.get("content-type")) { return parseXml(body).get("name"); } else ... } So that in the end I would be able to use: @RequestMapping(method = RequestMethod.POST) void processName(@RequestAttribute NameInfo name) { ... } Is there a way to achieve something similar to what I need? Thanks in advance.

• XNA 4.0 SpriteFont not displaying all Characters

  - by Iain Brown

  Am looking for a little help and trying to use SpriteFont in my XNA 4.0 game but the problem is am displaying to string "This is a test" but all that's displayed on the screen is "This is st" so the "a te" are missing from the screen. The space is there for the characters but the letters are not. The code am using is: spriteBatch.Begin(SpriteSortMode.BackToFront, BlendState.AlphaBlend); spriteBatch.DrawString(font,"this is a test",new Vector2(692,372),Color.White); spriteBatch.Draw(texture,new Rectangle(0,0,100,100),Color.White); spriteBatch.End(); Any help with this would be great!

• Unity Launcher Does Not Remember Favorites

  - by mpace965

  I have already looked at the similar questions, but none of the solutions there worked for me. Basically, I can edit and remove icons just fine when I am in a session, but the next time I am logged in, they are reset to the default. Even more perplexing is this. If I start dconf-editor, and navigate to desktopunitylauncher, it shows the favorites that are supposed to be there, yet the default ones are still in the Launcher. I have already tried sudo apt-get purge unity and then sudo apt-get install unity from a GNOME session, but to no avail. Any suggestions? Edit: I also tried running gksudo dconf-editor to run the program with elevated privileges. Again I navigated to desktopunitylauncher. This time the default string was there, but when I tried to edit it, it would not change to what I typed.

• mysql does not start or work

  - by Artem Moskalev

  Recently I installed LAMP with tasksel. Then I remember I issued some commands to get into the mysql console - it worked. Right now I checked - apache and php modules work perfectly. But as for mysql - whatever commands I issue - it does not start the console. It writes: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' How can I fix it and start mysql? Why did this happen? Where is it installed (I used the default location for the installation), because I dont understand what is started when I issue the commands?

• JAX-WS returning a complex object?

  - by occhiso

  Hi, Im pretty new to Java Web Services, but I cant find a good explanation anywhere. I have 2 Java web projects within NetBeans. One as a web service and one as a client for that web service. I have also created my own class called "Person", which has what you'd expect: name, dob, etc. I would like to have a web service method called "ListPeople()" that would return an array of "Person" objects. Do I need to have that class in both projects? Should I be serializing the object first? Should I be using JAXB, if so, where do I start? Sorry for the n00b questions, but im confused. What is the normal way of accomplishing this? Thanks in advance

• Best Practice for Utilities Class?

  - by Sonny Boy

  Hey all, We currently have a utilities class that handles a lot of string formatting, date displays, and similar functionality and it's a shared/static class. Is this the "correct" way of doing things or should we be instanciating the utility class as and when we need it? Our main goal here is to reduce memory footprint but performance of the application is also a consideration. Thanks, Matt PS. We're using .NET 2.0

• Python: Recursively access dict via attributes as well as index access?

  - by Luke Stanley

  I'd like to be able to do something like this: from dotDict import dotdictify life = {'bigBang': {'stars': {'planets': [] } } } dotdictify(life) #this would be the regular way: life['bigBang']['stars']['planets'] = {'earth': {'singleCellLife': {} }} #But how can we make this work? life.bigBang.stars.planets.earth = {'singleCellLife': {} } #Also creating new child objects if none exist, using the following syntax life.bigBang.stars.planets.earth.multiCellLife = {'reptiles':{},'mammals':{}} My motivations are to improve the succinctness of the code, and if possible use similar syntax to Javascript for accessing JSON objects for efficient cross platform development.(I also use Py2JS and similar.)

• LXDE keybind "Raise" window not working

  - by Campa

  I am using LXDE* over Ubuntu Oneiric on a DELL Studio-XPS 64-bit machine and I can't get the keybind for raising windows to work. In my ~/.config/openbox/lxde-rc.xml I put: <!-- Iconify window: it works. --> <keybind key="A-Down"> <action name="Iconify"/> </keybind> <!-- Raise window: does nothing. --> <keybind key="A-Up"> <action name="Focus"/> <action name="Raise"/> </keybind> then I openbox --reconfigure, but no rasing windows keybindings. I could use the NextWindow action, but... not really the same. References: http://openbox.org/wiki/Help:Bindings http://openbox.org/wiki/Help:Actions *Nested question: how to know the version of installed LXDE?

• Switch from encrypted partition to unencrypted (Error: cryptsetup: evms_activate is not available)

  - by Chris Lercher

  I initially installed Ubuntu 11.04 with an encrypted file system (from the alternate install CD: Guided Partitioning, LVM encrypted). Now I wanted to change this setup to have my root file system on an unencrypted partition. I had the following setup before: /dev/mapper/my-root on / type ext4 (rw,noatime,errors=remount-ro,commit=0,commit=0) /dev/sda1 on /boot type ext2 (rw,noatime) I backed up /, reformatted /dev/sda5 (which had contained the encrypted LVM device) to an ext3 partition, and restored / to that partition. I edited /etc/fstab, removed the line /dev/mapper/my-root / ..., and added the line: /dev/sda5 / ext3 noatime,rw,errors=remount-ro,commit=0 0 1 I edited /etc/crypttab, and commented out the single entry. On reboot, I get the grub screen as usual, but then I get the message cryptsetup:evms_activate is not available, waiting for encrypted source device. I tried reinstalling Grub2 using a LiveCD with the ChRoot method, but that didn't make any difference. Why is Ubuntu still searching for an encrypted device?

• Display brightness adjustment not working

  - by nibot

  I have Ubuntu 11.04 installed on a Lenovo Thinkpad T410 laptop with nVidia GT218 display controller. I am unable to adjust the display brightness. Pressing Fn-Home and Fn-End brings up the display brightness on-screen display and the indicated level increases or decreases as it should. But the actual display brightness does not change. Earlier I was able to Ctrl-Alt-F1 over to a text terminal and then do Fn-Home / Fn-End to successfully change the display brightness, and then Ctrl-Alt-F8 back to the Gnome session with the new brightness. But after upgrading to 11.04 the psuedoterminals have disappeared.

• Run your cpus fast but not hot

  - by John Paul Cook

  Paul Randall recently blogged about the importance of checking to make sure you are getting every bit of speed you should from your cpus. He recommended that people use CPU-Z , a free tool I recommend and have been using for many years. Power saving features in a cpu are great for laptops. Battery life is greatly extended when a processor isn't running to the max all of the time. But this isn't necessarily a good thing for a server. As Paul and others have pointed out, the processor might not get...(read more)

• Setup shortcut keys not working

  - by Tim

  In my Ubuntu 12.04, in keyboard settings, I didn't find a shortcut key for restarting X, so in "Customer Shorcut", I set up Ctrl+Alt+Backspace for command sudo restart lightdm. But after that the shortcut doesn't work. Is it because it requires root privilege? Also I have a SysRq key on my keyboard, which I think to be the "Magic SysReq Key". My SysRq key is shared with PrtSc key (for screen shoot), and is in blue which means I have to press Fn key at the same time to invoke SysRq instead of PrtSC. But every time I press Fn+SysRq, it always shoots a photo of the screen, same as just hitting PrtSc i.e. without hitting Fn. I wonder how to use the Magic SysReq Key? Does it mean the shortcut has not been linked to any command that is supposed for Magic SysReq Key yet? PS: My laptop is Lenovo T400 and OS is Ubuntu 12.04. Thanks!
