• Lost the system tray-bar and side panel dockbar disappears when touched

  - by defaye

  I have complete confidence that this problem will be resolved by restarting, however, it seems very odd that it should disappear randomly during my session. To put it simply, I've lost the top tray-bar and the side panel disappears when the mouse moves within touch, however if it click and drag the window by the side it comes back (but disappears instantly when touched again (however I can still click on the buttons where they should be). The only guess I have as to why it's happened is a bug, or I've lost a file these GUI things depend on. This is a real pain as some applications now have lost the "File, Edit" menu items as a result of this.

• How can I play a DVD-A (DVD-Audio) disc?

  - by Marek Grzenkowicz

  I was able to play such a disc using VLC, but I am wondering if any music player supports the DVD-A format. UPDATE: I checked Rhythmbox and Banshee - I found no option like Play Disc or Open Disc, so I have no idea how I could even try to start playing a DVD-A disc. This has also nothing to do with missing plug-ins or codecs - the packages gstreamer0.10-plugins-ugly, gstreamer0.10-plugins-bad and ubuntu-restricted-extras were installed on my machine before. I guess I am stuck with VLC (Totem shows a DVD menu, but then hangs). However, I am missing the regular music player experience - ability to change order of tracks, adding tracks to a playlist, listening only to selected tracks, etc. I found Idea #22415: Please add full support for DVD-Audio and LPCM at Ubuntu Brainstorm.

• Can I remove the latest ubuntu version without having to reinstall the old version?

  - by Emily

  I was using the 2.6 kernels with no problems, but when I updated to the 3.0 kernel, my bootup failed. I can manually boot with ctrl+alt+f1 startx and my login, but admittedly, i googled this and have no idea what I'm really doing. I have been trying to figure out how to go back to the old version, and eventually figured out the grub menu--i booted from all three 2.6 (.8, .10, and .11) editions of the previous version of ubuntu but they all had the same error as the 3.0 kernal. I can get logged in manually once the boot fails, but when i get to my desktop, wireless is not responsive and will not connect, and portable hard drives do not mount and/or are unresponsive. the previous version worked perfectly. I use an asus netbook. it's an eee pc. i don't have two OSs on it. i had to go to another computer to get to the forum... If the solution is simple, i just don't know what it is.

• 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 ?

• How can I selectively update XNA GameComponents?

  - by Bill

  I have a small 2D game I'm working on in XNA. So far, I have a player-controlled ship that operates on vector thrust and is terribly fun to spin around in circles. I've implemented this as a DrawableGameComponent and registered it with the game using game.Components.Add(this) in the Ship object constructor. How can I implement features like pausing and a menu system with my current implementation? Is it possible to set certain GameComponents to not update? Is this something for which I should even be using a DrawableGameComponent? If not, what are more appropriate uses for this?

• Change hotkeys/shortcut keys for volume control

  - by Daniel le Rouge

  I need to change the hotkeys for volume control, since I suffer from a bug, which disallows me to use the standard function hotkeys of my notebook. Since I have updated I to Oneiric, I am not able to change the settings for the hotkeys. It is neither possible in system settings nor in gconf-editor. Current buggy configuration: Volume mute: Fn + F3 Volume down: Fn + F4 Volume up: Fn + F5 Desired configuration: Volume mute: Ctrl + F3 Volume down: Ctrl + F4 Volume up: Ctrl + F5 If you need further information, I will be happy to provide it. I tried to overwrite the standard settings by creating a new one in the “Custom shortcuts” category. Even this attempt is unsuccessful. Is there a possibility to access this menu as root?

• JustCode Provides Reflector Alternative

  - by Joe Mayo

  If you've been a loyal Reflector user, you've probably been exposed to the debacle surrounding RedGate's decision to no longer offer a free version.  Since then, the race has begun for a replacement with a provider that would stand by their promises to the community.  Mono has an ongoing free alternative, which has been available for a long time.  However, other vendors are stepping up to the plate, with their own offerings. If Not Reflector, Then What? One of these vendors is Telerik.  In their recent Q1 2011 release of JustCode, Telerik offers a decompilation utility rivaling what we've become accustomed to in Reflector.  Not only does Telerik offer a usable replacement, but they've (in my opinion), produced a product that integrates more naturally with visual Studio than any other product ever has.  Telerik's decompilation process is so easy that the accompanying demo in this post is blindingly short (except for the presence of verbose narrative). If you want to follow along with this demo, you'll need to have Telerik JustCode installed.  If you don't have JustCode yet, you can buy it or download a trial at the Telerik Web site . A Tall Tale; Prove It! With JustCode, you can view code in the .NET Framework or any other 3rd party library (that isn't well obfuscated).  This demo depends on LINQ to Twitter, which you can download from CodePlex.com and create a reference or install the package online as described in my previous post on NuGet.  Regardless of the method, you'll have a project with a reference to LINQ to Twitter.  Use a Console Project if you want to follow along with this demo. Note:  If you've created a Console project, remember to ensure that the Target Framework is set to .NET Framework 4.  The default is .NET Framework 4 Client Profile, which doesn't work with LINQ to Twitter.  You can check by double-clicking the Properties folder on the project and inspecting the Target Framework setting. Next, you'll need to add some code to your program that you want to inspect. Here, I add code to instantiate a TwitterContext, which is like a LINQ to SQL DataContext, but works with Twitter: var l2tCtx = new TwitterContext(); If you're following along add the code above to the Main method, which will look similar to this: using LinqToTwitter; namespace NuGetInstall { class Program { static void Main(string[] args) { var l2tCtx = new TwitterContext(); } } } The code above doesn't really do anything, but it does give something that I can show and demonstrate how JustCode decompilation works. Once the code is in place, click on TwitterContext and press the F12 (Go to Definition) key.  As expected, Visual Studio opens a metadata file with prototypes for the TwitterContext class.  Here's the result: Opening a metadata file is the normal way that Visual Studio works when navigating to the definition of a type where you don't have the code.  The scenario with TwitterContext happens because you don't have the source code to the file.  Visual Studio has always done this and you can experiment by selecting any .NET type, i.e. a string type, and observing that Visual Studio opens a metadata file for the .NET String type. The point I'm making here is that JustCode works the way Visual Studio works and you'll see how this can make your job easier. In the previous figure, you only saw prototypes associated with the code. i.e. Notice that the default constructor is empty.  Again, this is normal because Visual Studio doesn't have the ability to decompile code.  However, that's the purpose of this post; showing you how JustCode fills that gap. To decompile code, right click on TwitterContext in the metadata file and select JustCode Navigate -> Decompile from the context menu.  The shortcut keys are Ctrl+1.  After a brief pause, accompanied by a progress window, you'll see the metadata expand into full decompiled code. Notice below how the default constructor now has code as opposed to the empty member prototype in the original metadata: And Why is This So Different? Again, the big deal is that Telerik JustCode decompilation works in harmony with the way that Visual Studio works.  The navigate to functionality already exists and you can use that, along with a simple context menu option (or shortcut key) to transform prototypes into decompiled code. Telerik is filling the the Reflector/Red Gate gap by providing a supported alternative to decompiling code.  Many people, including myself, used Reflector to decompile code when we were stuck with buggy libraries or insufficient documentation.  Now we have an alternative that's officially supported by a company with an excellent track record for customer (developer) service, Telerik.  Not only that, JustCode has several other IDE productivity tools that make the deal even sweeter.

• All tweak settings not saving after last 2 updates?

  - by mawburn

  I am running Ubuntu GNOME 14.04. After the last 2 updates, all settings in the Tweak menu are no saving. It will also not switch to the Gnome Dark theme at all. This includes all Startup Application changes as well as any changes to Extension settings. I'm not sure if I need to include any sort of log records or anything like that, so if you need any more information please ask. I've noticed the default fonts seem to be different. I don't remember that being part of the theme settings. It's almost like I'm running in Safe Mode.

• Extension Manager in Visual Studio 2010

  One of the powerful aspect of Visual Studio is its ability to be extended and many people do that. You can find numerous extensions at the Visual Studio Gallery. The VSX team links to a 4-part blog series on how to create and share templates. You can also look find extension examples on the vsx code gallery.With Visual Studio 2010, you can search for items and install them directly from within Visual Studio's new Extension Manager. You launch it from the Tools menu:When the dialog comes up, be sure to explore the various actionable areas on the left and also note the search on the right. For example, I typed "MP" and it quickly filtered the list to show me the MPI Project Template:Others have written about this before me, just bing Extension Manager (and note that Beta2 introduced changes, some of which you can witness in the screenshot above). Comments about this post welcome at the original blog.

• Dealing with "I-am-cool-and-you-are-dumb" manager [closed]

  - by Software Guy

  I have been working with a software company for about 6 months now. I like the projects I work on there and I really like all the people there except for 1 guy. That guy is technically smart, and he is a co-founder of the company. He is an okay guy in person (the kind you wouldn't want to care about much) but things get tricky when he is your manager. In general I am all okay but there are times when I feel I am not being treated fairly: He doesn't give much thought to when he makes mistakes and when I do something similar, he is super critical. Recently he went as far as to say "I am not sure if I can trust you with this feature". The detais of this specific case are this: I was working on this feature, and I was already a couple of hours over my normal working hours, and then I decided to stop and continue tomorrow. We use git, and I like to commit changes locally and only push when I feel they are ready. This manager insists that I push all the changes to the central repo (in case my hard drive crashes). So I push the change, and the ticket is marked as "to be tested". Next day I come in, he sits next to me and starts complaining and says that I posted above. I really didn't know what to say, I tried to explain to him that the ticket is still being worked upon but he didn't seem to listen. He interrupts me in-between when I am coding, which I do not mind, but when I do that same, his face turns like this :| and reacts as if his work was super important and I am just wasting his time. He asks me to accumulate all questions, and then ask him altogether which is not always possible, as you need a clarification before you can continue on a feature implementation. And when I am coding, he talks on the phone with his customers next to me (when he can go to the meeting room with his laptop) and doesn't care. He made me switch to a whole new IDE (from Netbeans to a commercial IDE costing a lot of money) for a really tiny feature (which I later found out was in Netbeans as well!). I didn't make a big deal out of it as I am equally comfortable working with this new IDE, but I couldn't get the science behind his obsession. He said this feature makes sure that if any method is updated by a programmer, the IDE will turn the method name to red in places where it is used. I told him that I do not have a problem since I always search for method usage in the project and make sure its updated. IDEs even have refactoring features for exactly that, but... I recently implemented a feature for a project, and I was happy about it and considering him a senior, I asked him his comments about the implementation quality.. he thought long and hard, made a few funny faces, and when he couldn't find anything, he said "ummm, your program will crash if JS is disabled" - he was wrong, since I had made sure it would work fine with default values even if JS was disabled. I told him that and then he said "oh okay". BUT, the funny thing is, a few days back, he implemented something and I objected with "But that would not run if JS is disabled" and his response was "We don't have to care about people who disable JS" :-/ Once he asked me to investigate if there was a way to modify a CMS generated menu programmatically by extending the CMS, I did my research and told him that the only was is to inject a menu item using JavaScript / jQuery and his reaction was "ah that's ugly, and hacky, not acceptable" and two days later, I see that feature implemented in the same way as I had suggested. The point is, his reaction was not respectful at all, even if what I proposed was hacky, he should be respectful, that I know what's hacky and if I am suggesting something hacky, there must be a reason for it. There are plenty of other reasons / examples where I feel I am not being treated fairly. I want your advice as to what is it that I am doing wrong and how to deal with such a situation. The other guys in the team are actually very good people, and I do not want to leave the job either (although I could, if I want to). All I want is respect and equal treatment. I have thought about talking to this guy in a face to face meeting, but that worries me that his attitude might get worse and make things more difficult for me (since he doesn't seem to be the guy who thinks he can be wrong too). I am also considering talking to the other co-founder but I am not sure how he will take it (as both founders have been friends forever). Thanks for reading the long message, I really appreciate your help.

• Windows no longer boots on dual-boot system

  - by N Alex

  While trying to delete an Ubuntu partition from my hdd I accidentally rebooted my computer. (Note: the partition was originally made from an existing partition using paragon.) After that when I tried to start the computer I got the GRUB rescue terminal prompt. I wasn't able to do much from that, but I did manage to boot Ubuntu from a USB drive and to run boot-repair. But now when I try to select Windows 7 from the boot selection menu I get the error 0xc0000225. Here is the link to the BootInfo summary created by boot-repair: http://paste.ubuntu.com/1032584/ I have a lot of very important data on my hdd and I would really appreciate your help.

• Game engine IDE template [on hold]

  - by Spencer Killen

  Hey so I'm working on a fairly basic javascript game, and it's beginning to get to the point where my 'engine' to which I wrote, is difficult to manage in an all text environment, Iv already thought of using a javascript IDE like jet brains, but i was wondering if I could go 1 step further and have use a piece of software to purpose as an IDE and have a customizable GUI that I could use to automate class construction and such, for example, I have it set up right now so that everytime I want to create a new block (it's a platformer) I must copy a text file and fill in all the setting such as bounding box, sprite ect, it would be a lot easier if I could press a button and have a menu apear where I would fill in these values (I have a game maker background) is there software like this? If not what are some similar solutions to my problem?

• Getting Black screen after installing 12.04 on new Mac Pro

  - by Matteo

  I installed Ubuntu 12.04 on my new Mac Pro. I had some problems because bootcamp did not allow me to partition the hd without a Windows cd. I inserted a Windows cd and did the partition and then I stopped the installation. I completed the installation of Ubuntu that now works. The problem is that Grub can't start Mac OS. It sees the Mac OS X in the menu but if I try to start it I have a black screen or sometime just the boot manager. Has anyone else experienced this problem?

• Can't see my partitions after grub recovery

  - by dimbo

  I stupidly inserted the windows CD into my dual boot Ubuntu 11.10 / windows xp system. I just wanted to see if I could install windows on my external usb HD, but didn't actually go ahead with the install. It seems like the windows CD messed up my MBR and I had to use boot-repair and the ubuntu 11.10 live CD to gain access to ubuntu again. It seems to boot up a little differently (slower) but works. However, I now cant see any of my partitions in nautilus (there are 3). When I open gparted, it just shows my whole hard drive as unallocated (I know it has a windows partition that works and my ubuntu partition that I am using now). If I insert a usb pen, it is also not visible in nautilus but in gparted shows up as a FAT32 partition (which is correct although I cannot access it). sudo fdisk -l gives the following : demian@dimbo-TP:~$ sudo fdisk -l [sudo] password for demian: omitting empty partition (5) Disk /dev/sda: 320.1 GB, 320072933376 bytes 240 heads, 63 sectors/track, 41345 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x877b877b Device Boot Start End Blocks Id System /dev/sda1 * 63 63842309 31921123+ 7 HPFS/NTFS/exFAT /dev/sda2 63844350 133484084 34819867+ 5 Extended /dev/sda3 127636488 133484084 2923798+ 82 Linux swap / Solaris /dev/sda4 133484085 625137344 245826630 83 Linux /dev/sda5 63844352 123445247 29800448 83 Linux /dev/sda6 123447296 127635455 2094080 82 Linux swap / Solaris Disk /dev/sdb: 8100 MB, 8100249600 bytes 12 heads, 40 sectors/track, 32960 cylinders, total 15820800 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc3072e18 Device Boot Start End Blocks Id System /dev/sdb1 * 5992 15820799 7907404 c W95 FAT32 (LBA) Here is my grub.conf file.

  I have a problem with my notifications on Ubuntu 14.04 x64. The notifications are just plain text with a colored background, and are also strangely placed in the top left corner. I have no idea on how it changed. After one reboot it was just there.. Here is a picture of the problem in question.: As you can see the notification appear over the unified menu. How can I restore the original state of the notification bubble? Here are the settings in ~/.notify-osd slot-allocation = fixed bubble-expire-timeout = 10sec bubble-vertical-gap = 5px bubble-horizontal-gap = 5px bubble-corner-radius = 37,5% bubble-icon-size = 30px bubble-gauge-size = 6px bubble-width = 240px bubble-background-color = 131313 bubble-background-opacity = 90% text-margin-size = 10px text-title-size = 100% text-title-weight = bold text-title-color = ffffff text-title-opacity = 100% text-body-size = 90% text-body-weight = normal text-body-color = eaeaea text-body-opacity = 100% text-shadow-opacity = 100% If I check the org.freedesktop.Notifications.service(/usr/share/dbus-1/servies) it appears to use the correct one. [D-BUS Service] Name=org.freedesktop.Notifications Exec=/usr/lib/x86_64-linux-gnu/notify-osd

• Run application in specific X server or VNC port

  - by SirCharlo

  I have an application that I'd like to run, yet I'd like it to be visible only through a certain VNC port. I don't want the app to show up on the normal Ubuntu desktop. I want the app to run "in the background", and be viewable through VNC only. And when connected to this "alternate X server", the end-user wouldn't see any menu bars, no window decorations.. Just the app. Come to think of it, what I'm asking for is a sort of kiosk-mode for only a certain app, accessible through VNC. Is this possible or am I really reaching here? Thanks! Note that the app I wish to run in this fashion is written in Java. It is a JNLP file.

• How do I fix DNS resolving which doesn't work after upgrading to Ubuntu 13.10 (Saucy)

  - by Witek

  After upgrade to 13.10 my DNS resolving fails. It seams the DNS servers which I get by DHCP (LAN) are not used. I could temporary solve the problem by adding nameserver 8.8.8.8 to /etc/resolv.conf. But then the intranet hosts still can not be resolved. When clicking on the Connection Information menu item on the network indicator, the Primary DNS and the Secondary DNS are set correctly. But my computer seams not to use them. So my questions: What should I put into resolv.conf, if anything? How to find out, which name servers my computer is querying? Where to look next, to find out, why name servers received by DHCP are not used?

• ACER ASPIRE ONE, WIFI Atheros Communications Inc. AR9462 problem with 12.10

  - by antoine

  I have an ACER ASPIRE ONE AO756-Series, equipped with A wifi controller Atheros Communications Inc. AR9462 Everything worked fine on 12.04, but when I upgraded to 12.10 I experimented some issues : * wifi does work ! * still, the wifi icon/menu does not react normally : 1) it is always grey, hence not indicating if connected or not, 2) It does not react to me clicking on it (disconnect, change the network, desactive wifi, etc) So it's not a critical issue because I can change the active wifi connection through control pannel, but it is very annoying. Do you know of an solution around this issue ? thanks a lot antoine

• How to Name Groups of Apps on the Windows 8 Metro Start Screen

  - by Taylor Gibb

  The Windows 8 Start Screen certainly takes some getting use to, however, one of the things that I really miss about the Start Menu was how i was able to categorize my installed applications. While you cant create folders on the Start Screen, you can group your applications. To get started head over to the Metro Start Screen and move your mouse to the bottom right-hand corner, clicking on the small icon. Now right click on the group of apps that you want to name.

• After upgrade from 10.10 to 11.04 Ubuntu doesn't load the splash screen anymore

  - by Vincent Vega

  I have the problem that Ubuntu doesn't load the splash screen anymore (after upgrading from 10.10 to 11.04). After the Grub-bootloader, it takes a few seconds to load and then the monitor turns black. I already tried to boot from a Ubuntu Live CD, but the result was the same error. Furthermore I tried to start the protected mode, but it freezes just after showing me menu. Do you have any solutions for this? And is it possible to switch from Grub to the Ubuntu console?

• Things to install on a new machine revisited

  as I prepare to get a new dev machine at work, I write the things I am going to install on it, before writing the first line of code on that machine: Control Freak Tools: Everything Search Engine a free and amazingly fast search engine for files all over your machine. (just file names, not inside files). This is so fast I use it almost as a replacement for my start menu, but its also great for finding those files that get hidden and tucked away in dark places on my system. Ever had a situation...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.
