• Ubuntu 12.10 ATI Driver 12.11 fails after compiz and xorg update

  - by Lukasz W.

  I updated my system via the package manager from Unity and next restart was just blackness. After being here: http://linux.hootip.com/amd-catalyst-12-11-beta-fix-and-installation-the-drivers-on-ubuntu-12-11/ I had the Catalyst 12.11 Beta driver installed. I checked my /var/log/apt/history.log and the update I received was of compiz and xorg packages. I tried to get latest release info, but all I get from their pages are commit info; I can't tell what was n the package update I got served. Anyone knows what was in the latest xorg/compiz release that broke the driver? Which driver should I use now? For completeness this is how I got the system back to boot (probably lame and not elegant): Boot with GRUB selection "More Ubuntu options (or sth like that), From secondary screen select 3.5.0-19 with boot options, When system prompts on stuff you'd like to do, select "root" - Drop to root shell, There: # mount -o remount,rw / # mv /etc/X11/xorg.conf /etc/X11/xorg.conf.failed # /usr/share/ati/fglrx-uninstall.sh # reboot This got be back on my feet.

• Boot from external usb hdd won't work in 12.04

  - by Ben Andersen

  I've been running 10.04 on an external USB HDD without problems for years. I installed 12.04 on an external USB HDD and it worked until I upgraded to all the new packages. But after that it wouldn't boot. I just got into the grub prompt. So then I tried installing on the disk inside the computer and that worked fine. But when I take it out and use it as an external USB HDD I just get: error: hd0 out of disk. grub rescue> How can I fix this? So why do I want this you might wonder? Well I have a laptop at home and a somewhat similar at work. And I just move the disk between them and don't have to move a heavy laptop. So I really hope I can continue doing this with 12.04! The old disk is only 80Gb but the new one is 320Gb (7200rpm Toshiba). I'm using 12.04 on a 64Gb SSD as an external drive and it warns about out of disk but it boots anyway most of the times.

• Oracle Java Embedded Client 1.1 Released

  - by Roger Brinkley

  Yesterday an update release of Oracle Java Embedded Client (OJEC) 1.1 quietly slipped out door for general availability. Until last year it was pretty difficult to get your hands on either a Connected Limited Device Configuration (CLDC) for small devices or a Connected Device Configuration (CDC) for medium devices java implementation without a substantial initial commitment. But with the the release of OJWC (CLDC) and OJEC (CDC) last year that has changed. OJEC 1.1 is a binary distribution designed for installation on medium configurations which is a mid range processor requiring a  slow startup time, seamless upgrades, in a cost sensitive hardware environment  anywhere from 3.5mb to 8 mb. There are headless as well as headed versions available. It is intended for devices, such as Blu-­-ray Disc players, set-­-top boxes, residential gateways,VOIP phones, and similar. From a software point of view, OJEC is the Java runtime platform implementation of Connected Device Configuration (CDC v1.1, JSR-­-218), Foundation Profile (FP v1.1, JSR-­-219), and Personal Basis Profile (PBP v1.1, JSR-­-217)  and includes optional packages RMI (JSR 66), JDBC (JSR 169) and XML API for Java ME (JSR 280), and Java TV (JSR-­-927). New to this release is support for the XML API (JSR 280) and a number of bug fixes and performance enhancements, including an improved Just-in-Time (JIT) compilation for the x86 chipset architecture. The platforms supported include ArmV5, ArmV6/ArmV7, MIPS 32 74K, and X86 in headless mode. For embedded developers there are number of advantages to using Java and if you have shied away from the JavaME edition in the past I would encourage you to look into the updated version of OJEC 1.1.

• How to hide the mouse cursor

  - by MvG

  I'm building a kiosk using Ubuntu Precise on a touch screen. Now I'm looking for the appropriate way to make the mouse cursor disappear. As people know where they are pointing, displaying an arrow under their finger is useless, and having an error where they last pointed even more so. My best bet would be some kind of cursor theme consisting only of transparent cursors. I'm a bit surprised to find no UI to switch and maybe install cursor themes the default Unity UI, but as I won't be using Unity, that's not much of a problem. It appears that the alternatives listed in update-alternatives --list x-cursor-theme all refer to .theme files, so I searched the package list for those. The resulting list does not list any likely candidates, i.e. no packages containing “invisible” or “transparent” in their name. So far, some googled result yielding a readme for “XCursor Transparent Theme” is my best bet. That would mean compiling those sources myself, perhaps putting them into my PPA. I'm also a bit sceptical about that result as said readme is dated from 2003. And I'm not sure that I'm not making things overly complicated. After all, there is quite some support in Precise for touch devices, so I don't believe I'm the first one who wants to get rid of his mouse cursor. Is there another way which doesn't involve user-compiled binary code? Is there a theme package for transparent cursors which I've overlooked? Is there some other mechanism to make the cursor disappear without changing the cursor theme? I'll be using Matchbox WM, Firefox and Java applets, so I'll be happy with any solution working under such a setup. I'm not interested in any solutions twiddling with Gnome or Compiz, as I'll not be running either.

• Are the Ubuntu ISO images updated From release .ubuntu.com

  - by tijybba

  Just got idea from this(may not be related though) question however. Are the ISO images from the official site updated with updates in Core Ubuntu system , like Kernel Updates , desktop Environment Updates(unity), i mean Updates of BASE system including X-org, Office suite, Package Manager , Update manager or Gnome Base Modules, those released in update Branches like precise-Updates branch. The reason i am asking this is , if i download the ISO image of Ubuntu 12.04 Say after two or three months from release , i have to do an update of approximately 200~300 MB's size. So why are these ISO images not updated to recent updates, i am aware that all of the components are not updated at the same time , but let's say after One month from actual release ( Both LTS and normal releases), the updated components can be added to form a Updated ISO in regular intervals, which provides new users to use latest versions and features with improved stability and less bandwidth Consumption. I am not mentioning the idea of comparison to Rolling Release , or External PPA's added updates , and neither Netinstal but the ISO of updated Packages .This can be provided as optional download. Since my question is within the boundary of Official updates releases so stability could not be the reason. I guess there are custom packagers out there , but having an official option would be better. It helps in distributing Newest ISO OS which impresses a lot new users , since it makes availability of newer features and a faster system ofcourse. Another reason of asking this is here. Edit: Since almost all new (Desktop) users download the Default ISO's having one or few issue , which may have been corrected in following updates. But most of new laptop users i encountered gave up because of it , so should i suggest ,for laptop not listed on Certified H/W list , to try daily Builds , if needed.

• Handy Tool for Code Cleanup: Automated Class Element Reordering

  - by Geertjan

  You're working on an application and this thought occurs to you: "Wouldn't it be cool if I could define rules specifying that all static members, initializers, and fields should always be at the top of the class? And then, whenever I wanted to, I'd start off a process that would actually do the reordering for me, moving class elements around, based on the rules I had defined, automatically, across one or more classes or packages or even complete code bases, all at the same time?" Well, here you go: That's where you can set rules for the ordering of your class members. A new hint (i.e., new in NetBeans IDE 7.3), which you need to enable yourself because by default it is disabled, let's the IDE show a hint in the Java Editor whenever there's code that isn't ordered according to the rules you defined: The first element in a file that the Java Editor identifies as not matching your rules gets a lightbulb hint shown in the left sidebar: Then, when you click the lightbulb, automatically the file is reordered according to your defined rules. However, it's not much fun going through each file individually to fix class elements as shown above. For that reason, you can go to "Refactor | Inspect and Transform". There, in the "Inspect and Transform" dialog, you can choose the hint shown above and then specify that you'd like it to be applied to a scope of your choice, which could be a file, a package, a project, combinations of these, or all of the open projects, as shown below: Then, when Inspect is clicked, the Refactoring window shows all the members that are ordered in ways that don't conform to your rules: Click "Do Refactoring" above and, in one fell swoop, all the class elements within the selected scope are ordered according to your rules.

• Small change in MVVM Light Toolkit templates for Blend 4 RC

  - by Laurent Bugnion

  Ah, the joy of new releases… You will find that the MVVM Light Toolkit works fine with Visual Studio 2010 RTM and Blend 4 RC except for a few adjustments: Blend templates The path to the Expression Blend 4 project templates changed. If you start Expression Blend 4 RC now, you will likely not see the MVVM Light templates in the New Project dialog.   New Project dialog with MVVM Light To restore the templates, follow the steps: Open Windows Explorer Navigate to C:\Users\[username]\Documents\Expression (or simply type My Documents in Windows Explorer and then open the Expression folder). Change the name of the “Blend 4 beta” folder into “Blend 4”. That’s it, you should now see the templates in the New Project dialog in Blend 4. Note that since the new name is “Blend 4”, I hope that I won’t need to do the same exercise when Blend 4 RTM is released! Windows Phone 7 templates Since the Windows Phone 7 tools are not ready yet for Visual Studio 2010 RTM and Blend 4 RC, the templates in the Silverlight for Windows Phone folders will not work. You will get an error if you try to create a new such project in the newly released environment. I hesitated to remove these templates from the current packages, but honestly that is a lot of trouble for a very short time before the tools for Windows Phone 7 are released (note: I don’t have any information as to when these tools will be released). In the mean time, just don’t create a WinPhone7 application. Reminder: If you want to write code for Windows Phone 7, you need to keep the Visual Studio 2010 RC as well as Expression Blend 4 beta. Updated package I uploaded an update to the Blend 4 templates. It is available like before on the “Install manually” page and on the Codeplex page.   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

• How do I copy a package from Debian to my PPA?

  - by Bernhard Reiter

  I'd like to add the latest gourmet package from Debian sid to our team's PPA so Ubuntu users who would like to run an up-to-date version of Gourmet can add that PPA to their software sources. (Dependency-wise, that shouldn't be much of an issue as pretty much all our current dependencies are already available in all currently supported Ubuntu versions.) I've downloaded the *.dsc file and debian and orig tarballs, and even figured out I could use this for the package's source.changes file. I also downloaded the Debian maintainer's public key so dput can validate the package. I then tried to upload the package to our PPA using dput ppa:~gourmet/ppa gourmet_0.17.3-1_source.changes (I also tried without the tilda.) This seemed to succeed, but I didn't get a confirmation email, and no packages are now displayed at our PPA, which leads me to believe that the package was rejected because the Debian maintainer's key is obviously not among our team members' keys. So what's the easiest way to "copy" a package from Debian (sid) to a Launchpad PPA? Do I really need to rebuild the entire package locally before I can upload it?

• Script Task/Component and Template Information

  The Script Task and Script component are often used by people developing SSIS packages because they are easy to use and now because SSIS could be perceived to be more developer friendly they are very powerful. That being said we should no be using them everywhere.  There are generally Tasks/Components already provided that will do the job it may be that we have to rethink the way we want to draw our package. I had cause last week to break out the script component in SQL Server 2008 SP1 and found that it was broken.  I don’t know when it broke as I do not use them all that often.  My error was as below.     Something must have overwritten this template information.  I looked in Event Viewer and tried the things it suggested but the templates still did not work.  Here is how I got them eventually to work for me (Your Mileage may vary) Open up a Command Prompt window using an administrator level account and “as an administrator” vsta.exe /hostid SSIS_ScriptTask /setup vsta.exe /hostid SSIS_ScriptComponent /setup   This worked for me.  Hope it helps.

• Release/Change management - best aproach

  - by Bob Rivers

  I asked this question an year ago in StackOverflow and never got a good answer. Since Programmers seems to be a better place to ask it, I'll give it a try... What is the better way to work with release management? More specifically what would be the best way to release packages? For example, assuming that you have a relatively stable system, a good quality assurance process (QA), etc. How do you prefer to release new versions? Let's assume that we are talking about a mid to large "centralized" web system (no clients), in-house development. This system can be considered "vital" for a corporate operations. I have a tendency to prefer to do this by releasing packets at regular intervals, not greater than 1 to 3 months. During this period, I will include into the package,fixes and improvements and make the implementation in production environment only once. But I've seen some people who prefer to place small changes in production, but with a greater frequency. The claim of these people is that by doing so, it is easier to identify bugs that have gone through the process of QA: in a package with 10 changes and another with only 1, it is much easier to know what caused the problem in the package with just one change... What is the opinion came from you?

• Ubuntu 12.04.3 64 bit with Nemo 2.0.x no thumbnails

  - by Dr. Szrapnel

  I have strange problem with thumbnails in my Ubuntu machine. I was using Ubuntu with Cinnamon 1.8 from stable ppa and it was good but then Cinnamon 2.0 came out with some broken packages uploaded to stable ppa nad things gone wrong... Anyway after few updates Cinnamon started to work normaly except Nemo - there are no thumbnails at all, only icons. I heve tried purging /.cache/thumbnails and .thumbnails folders but this doesn't work. Next I have changed permissions for those folders - that didn't helped either. Then I've set Nemo as default file manager and desktop handler but with no result. What is weird - when I start Nautilus and open some folder with images then close it and open same folder with Nemo thumbnails appears but when I clean thumbnails directories there are no thumbnails again. It would be great if someone have some solution for this annoying Nemo behavior because I really don't want to resign from Cinnamon. p.s. I have set preview options in Nemo for Always and no bigger files than 4GB so that is not the case.

• How much knowledge do I need to begin a project in Django

  - by Smock

  I started learning django about a month ago. I have an intermediate C, Java programming experience. I read the first 8 chapters of the django book . Afterwards, I picked up Practical Django Projects by James Bennett and did the first two projects: CMS & Web Blog. Although, I started getting lost when he got to the generic views part. I know that's important but I'm not sure how important that is when trying to implement a project. Anyway, I have a project in mind that I'd like to start; however, I'm nervous as to where to begin. I'm overwhelmed with the number of things that I'd like my project to do but no knowledge or minimal knowledge as to how e.g. how do i implement css and javascript in my project. Moreover, I am aware that some django packages exists to ease development but I don't know if I should use them or not. Anyway, I apologize for my length message. I just want some advice/encouragement. I have a project in mind but do you think I need to read more materials/tutorials or is it smart to just start working on my project based on the minimal knowledge i've gained from those books? Any information that can be provided is much appreciated. I really want to get good at this but I just need some direction.

• Is this project Structure Valid?

  - by rafuru

  I have a dilemma: In the university we learn to create modular software (on java), but this modularity is explained using a single project with packages (a package for business, another one for DAOS and another one for the model, oh and a last package for frontend). But in my work we use the next structure: I will try to explain: First we create a java library project where the model (entities classes) are created in a package. Next we create an EJB named DAOS and using the netbeans wizard we store the DAOS interfaces in the library project in another package , these interfaces are implemented in the DAOS bean. So the next part is the business logic, we create a business EJB for each group of functions , again using the wizard we store the interface in the java library project in another package then is implemented on the business bean. The final part (for the backend) is a bean that I have suggested: a Facade bean who will gather every method of the business beans in a single bean and this has an interface too that is created in our library project and implemented in the bean. So the next part is call the facade module on the web project. But I don't know how valid or viable is this, maybe I'm doing everything wrong and I don't even know! so I want to ask your opinion about this.

• Recent update killed unity 3d launcher

  - by Steve

  I am scratching my head on this one, a lot of things are still new to me. I updated 126 packages just now through the update manager, and upon reboot everything works fine except the unity launcher. It's just a dark space. The dash still works, as does the top panel and docky.

• How to build the mainline kernel source package?

  - by Maxime R.

  Ubuntu kernel PPA only provides linux-headers*.deb and linux-image*.deb packages. How can I build the corresponding linux-source*.deb package ? Context: I'm currently running Ubuntu 11.10 with the mainline kernel (3.2 rc6 now) to get a better support for my sandybridge IGP (Dell E6420 laptop with intel i5-2520M CPU). Appears, i'd like to install this touchpad driver, ALPS touchpads being badly supported (see previous link bug report), while waiting for upstream support in kernel version 3.3. Problem is, DKMS keeps complaining about not finding the full kernel source: Module build for the currently running kernel was skipped since the kernel source for this kernel does not seem to be installed. Appears I may not need the full source but I'd still like to try having it installed to see if it solve my problem. What I tried : Uncompressing the kernel.org source archive in /usr/src/. DKMS still complaining. Manually updating the kernel source package with uupdate and the mainline source package like explained here. Did not succeed. Manually building the linux-source package following @roadmr and @elmicha instructions. I eventually succeeded to build it but DKMS still complained about the missing source. At last I noticed an error I did not catch in the first place while reinstalling the kernel headers. Appears the .deb I got may have been corrupted, downloading it again did the trick :) Alas, while DKMS agreed to compile the module i ran into the following error which appears to have already been reported. This issue isn't yet solved but I won't try to because of the following: in the end I decided to test the precise kernel version 3.2-rc6 through the xorg-edgers ppa which appears to be correctly patched: it works. Nevertheless, it might still be of some interest to know how to build the mainline linux-source package as the Ubuntu Kernel Team doesn't provide it. Not to mention that I learned a lot in the process ^^

• ASP.NET website deployment [on hold]

  - by Rei Brazilva

  I am getting my hands wet with ASP and I have been following the tutorials. I deployed the site and in Azure and it worked great. Today I started actually designing the site. And when I published, it looks as if it doesn't read any of the files I just updated, added, and modified. It works on my localhost, but not in the Azure. I thought when you publish, everything goes up, including the new files. I don't have enough reputation to add a picture so, you'll forgive me. SO, basically, how do I get my entire site uploaded? In case anyone does stop by, I was able to pull this out just recently: CA0058 Error Running Code Analysis CA0058 : The referenced assembly 'DotNetOpenAuth.AspNet, Version=4.0.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246' could not be found.

• Windows Randomly Stop Accepting Input from Bluetooth Keyboard

  - by dragonmantank

  I've got a laptop running Ubuntu 11.10 with the most recent updates and an Apple Wireless Keyboard that syncs via bluetooth. The Ubuntu box is also a Synergy server, using QuickSynergy to run Synergy. I'm using xmodmap to swap the option and command keys, but nothing else. Throughout the day, windows that are long running will just stop accepting input. For example, I leave gnome-terminal up and running almost 24 hours a day. If it sits for a while, it just stops accepting input. It doesn't matter if I'm ssh'd into another machine or sitting on a local tty session, it just stops accepting input. If I open a new tab or window, those work fine. The 'broken' tabs stay broken. I'm also running Turpial (a Twitter client) which will do that same thing. I tend to use the arrow keys to navigate, and it just stops accepting input. Closing it and reopening it causes it to work fine. I don't seem to have the problem in Chrome, but I tend to open up new tabs when I go somewhere instead of using existing tabs. I've updated all the packages, rebooted, and the only thing that seems to cure it is if I type on the built-in keyboard, the window will start to accept text from the bluetooth keyboard (until it stops again). I don't think the keyboard is disassociating from the laptop because it can happen while I'm using the keyboard, it seems more linked with windows that I sit for a long time. As an example, I'm typing in Chrome with the bluetooth keyboard but I have a terminal window that won't accept input.

• There's IP but can't reach gateway

  - by icky

  I have just installed ubuntu 12.04 on my new laptop, and brought it back to home, but I found the wireless network does not work. Strangely, it has the correct ip, but can't connect to the gateway. ifconfig gives ip 192.168.64.36, with broadcast 192.168.79.255 and mask 255.255.240.0, this are all correct, the gateway is at 192.168.64.1 cat /etc/resolv.conf nameserver 192.168.64.1 nameserver 127.0.0.1 which i think it's also right. but when I ping 192.168.64.1, all packages are lost.

• Creating, using and managing XML component dictionaries quick tutorials

  - by drrwebber

  XML Component Dictionary capabilities are provided in conjunction with the CAM Editor toolset.  These dictionaries accelerate the development of consistent XML information exchanges using standard sets of dictionary components. The quick tutorials are aimed at showing the 'how to' of the basic capabilities to jump start use of XML dictionaries with the CAM Editor. The collection of dictionary tutorials videos run for a total of approximately 20 minutes.  Each video can be reviewed individually also. Learn how to use the dictionary functions to create dictionaries by harvesting data model components from existing XSD schema, SQL database table schema, or simple Excel / Open Office spreadsheets with tables of components listed.Also included are tips and functions relating to use of NIEM exchange development, IEPD and EIEM techniques.These videos should be viewed in conjunction with reviewing the overall concepts and techniques described in the companion video on the CAM Editor and Dictionaries overview.  The approach is aligned with OASIS and Core Components Technical Specification (CCTS) standards specifications for XML components and dictionaries.Dictionary collections can be stored locally on the file system, or local network, or collaboratively on the web or cloud deployment, or can be shared and managed securely using the Oracle Enterprise Repository (OER) tool. Also included are techniques relating to the use of the NIEM approach for developing XML exchange schema and IEPD packages.  This includes generating reuse scores, wantlist, and cross reference spreadsheets. Included in the latest release of the CAM Editor is the ability to use the analyse dictionary tool to determine duplicate components, conflicting component definitions, missing component descriptions and so on.  This ensures high quality dictionary component specifications.  Using the CAM Editor you can also create MindMap models and UML physical models of your dictionary components sets. For a complete guide to using the CAM Editor see the main YouTube video tutorials website and the CAM Editor website.

• Why can't I install from software center?

  - by user64720

  There was a problem upgrading to Firefox 13. This error kept returning: /var/cache/apt/archives/firefox_13.0+build1-0ubuntu0.12.04.1_i386.deb W: Waited for dpkg --assert-multi-arch but was not there - dpkgGo (10: There are no "child" processes). Now it seems that there is some problem with dpkg and I can't install anything from software center. I already tried to clean previous packages with sudo rm /var/lib/apt/lists/* -vf and then sudo apt-get update, it didn't work. When running sudo dpkg --configure -a, I get this: dpkg: problems with dependencies prevent the configuration of firefox-globalmenu: firefox-globalmenu depends on firefox (= 13.0+build1-0ubuntu0.12.04.1); however: The package is not installed. dpkg: error while processing firefox-globalmenu (--configure): problems com dependencies - leaving unconfigured There has been found errors while processing: firefox-globalmenu What should I do to fix this?? EDIT: I don't have the necessary expertise to understand why what I did worked and what was causing the conflict, but anyway, since there was a problem with firefox-globalmenu:, I went to synaptics package manager, I removed this particular package and reinstalled it. After that, I was able to install Firefox from synaptics and also any other applications from software center. However, still there was a problem, when running sudo apt-get update, the following kept returning: Failed to get gzip:/var/lib/apt/lists/partial/archive.ubuntu.com_ubuntu_dists_precise_main_binary-i386_Packages Verification code hash doesn't match. E: Some archives index failed at being downloaded. They have been ignored, or older copies are used instead. So I typed sudo rm /var/lib/apt/lists/* -vf in terminal and then again sudo apt-get update and everything is fine now. I did this before an answer was posted, anyway I agree the problem was that particular package and its removal. So I'll mark the below answer as accepted.

• New Book - Oracle ADF Enterprise Application Development Made Simple

  - by Shay Shmeltzer

  It's nice to see another ADF book out there, this one from Sten Vesteli titled "Oracle ADF Enterprise Application Development Made Simple" comes from Packet Publishing Unlike other ADF books out there, this one doesn't aim to teach you Oracle ADF, but rather focuses on the right way to structure and manage a project that leverages ADF. This is a welcomed addition to the bookshelf for people who are looking into ADF based development. One thing I find is that some organization just start developing an ADF application without first doing much planning, something that is understandable given that it is very easy to start building a prototype with ADF and then just grow it into a full blown application. However, as the book points out, doing a bit of planning before you delve into the actual project development can save you a lot of time in the future. For example it is much better to have the right breakdown and structure of your project to allow you to do efficient team development right out of the gate, then to find out 1 year down the road that you are dealing with one monolithic size project which is hard to manage. The book touches on such topics as project organization (workspaces, projects, packages), planning your infrastructure (templates, framework classes), coding standards, team structure, etc. It also covers various aspects of application lifecycle management such as versioning, build, testing, deployment and managing requirements and tasks and how all of those are done when using JDeveloper and Oracle ADF. It's nice to see that the book covers working with Oracle Team Productivity Center - a solution that might not be getting the exposure it deserves. The book also has some chapters about security, internalization and customization of applications both with MDS and with ADF Faces skins (and it even covers the brand new skin editor). Overall I think this is definitely a book you should read if you are about to start your way on a new enterprise scale ADF application. Taking into account the topics that the book discusses before you start your work will save you time and effort down the road. By the way, don't forget that as an OTN member you can get discount on this and other books.

• GNOME changes to KDE on Maverick

  - by Pit

  Hi, I recently made a clean/fresh install of Ubuntu 10.10 an experienced the problem that the theme changes from Gnome to KDE and back randomly and partly. Sometimes after starting my computer I will have a KDE theme. If I then open the Appearance Preferences ( System - Preferences - Appearance ) some applications and the main-menu as well as menu of applications (only upper two centimetres of a application window) will change back to Gnome only by opening it, not changing anything nor saving. I did not choose KDE at any time, nor did I do any changes to the appearance prior to the first occurrence of this bug. On a second computer I updated from 10.04 to 10.10 and experienced the same bug. On this computer I did however change the layout of the minimize;maximise;close buttons by following How do I move the Window buttons from left to right?. But I don't see how this could provoke the bug, especially as it occurs on a second computer. Will doing updates I saw that there a quite a lot of KDE packages being downloaded. Do I even need those if I don't want to use KDE?

• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

  - by oyse

  I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card. I know I can manually download the drivers directly from Asus, but I would rather not go that route. If there are anyone that knows about any packages or other things I can do to make this work would be much appreciated. Some systems details: $ lsb_release -a No LSB modules are available.
