• Error after installing Lubuntu 14.04 through liveUSB

  - by Veritas

  A friend asked me to install ubuntu on his toshiba NB 200 netbook to replace windows xp. I formatted the flash drive, ran an nb5sum check on the iso and after running netbootin , I checked the drive for errors. No problems so far. During the installation, while everything seemed normal, the installation regularly paused until I pressed a button or moved the mouse. After restarting, it doesn't boot and it starts a shell showing : "General error mounting filesystems A maintenance shell will now be started CONTROL-D will terminate this shell and reboot the system " Any ideas? Any help is appreciated!

• How to find manually installed packages?

  - by queueoverflow

  I installed a plain Ubuntu 10.10 on my computer and installed some software via apt-get. Last week I managed to break everything and just started from scratch, and I need to reinstall my software. Is there some way to create a list with all the packages that I have installed manually? So that it would give me a list like „texlive, ...“ and not „texlive, texlive-dep1, textlive-dep2, ...“ and all the standard packages removed? If I could somehow figure out which programs out of the regular install I have removed, that would be awesome too!

• Why doesn't the installer see all of my hard drives?

  - by atodd

  I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed. I've tried everything I know. I'm not sure if its a BIOS setting or something else I've missed. I've also tried both the desktop and alternate amd64 installs with the same result.

• How to use GetActiveUniform (in SharpGL)?

  - by frankie

  Generally, guesting is in header. I cannot understand how to use GetActiveUniform function. public void GetActiveUniform(uint program, uint index, int bufSize, int[] length, int[] size, uint[] type, string name); My attempt looks like this (everything is compiled and linked): var uniformSize = new int[1]; var unifromLength = new int[1]; var uniformType = new uint[1]; var uniformName = ""; Gl.GetActiveUniform(Id, index, uniformNameMaxLength[0], unifromLength, uniformSize, uniformType, uniformName); After call I get proper uniformSize, length and type, but not name.

• Boots to terminal

  - by Core Xii

  I had a system running 10.04, I think. I upgraded it to 11.04, everything was fine. But then when I upgraded it further to 11.10, the system would only boot to a terminal, no desktop like before. I installed 12.04 on it instead, keeping /home which was on another partition... but it's still booting to terminal. I believe there may be some bad configuration files left over that are causing this. Looking at other similar issues, I looked for /etc/X11/xorg.conf but it doesn't exist. startx says it isn't installed. Installing nvidia-current didn't help (has GF 6600 GT video card). Alt+F7 shows a blank screen. I used the alternate installer, and didn't select any of the optional packages it prompts during installation. Should I have? How do I get it to boot to desktop like normal?

• How should I expand Jenkins to help me release? [closed]

  - by Amy Worrall

  Pushing new Sparkle releases of our internal apps is a pain. I have to make the build, make the release notes file, sign the .zip with the private key, and add a new entry to the appcast file tying everything together. I'd love it if Jenkins could help: use the commit messages for the release notes, and automatically do the rest of it. Should I be looking at writing a new Jenkins plugin, or using shell scripting, or is there something already that will do what I want? (A quick Google didn't find anything.)

• Installing g++ on 8.04

  - by mathematician1975

  I am running Ubuntu 8.04 (currently I do not have the option to upgrade due to hardware problems). I need to get g++ onto my installation but as this is no longer supported I am unable to use the traditional apt-get approach. What are my options? Are ubuntu packages configured specifically for each version? For example could I manually download a later version of gcc and g++ that do not originally ship with 8.04 (say the 10.04 version for example) and build them from scratch? Do the compilers work in this way in the sense that they have a version PER ubuntu version or are they maintained as separate entities?? I do not know enough about ubuntu internals really and always use apt-get to obtain/update any packages I need. If it is possible to do it this way is there a way to be certain that I have everything I need with regards to utility packages needed by g++ for the installation??

• How should I structure a solution for a long term project?

  - by sooprise

  I'm about to create a do-everything dashboard for my team and am still having second thoughts about my project/solution structure. Since this could be a long ongoing project, I want to get the structure right from the beginning. This is what I had in mind: Create a solution named "doEverythingDashboard" Delete the project named "doEverythingDashboard" under the solution "doEverythingDashboard" Create winform project named "interface" Create console applications projects for each functionality of "doEverythingDashboard" Reference each console application in "interface" Does this make any sense? Would it make more sense to just have one project and create a class per functionality instead of an entire project?

• Gnome/X logs off immediately after login -- which logfiles are relevant?

  - by joebuntu

  I've been tinkering with fingerprint-gui as well as X/xrandr resolution settings. When I start my machine, it boots up normally. As soon as X and gnome have finished starting, it logs me off automatically and brings me back to the gdm login prompt with the user list. Then I am, however, able to log in using "Ubuntu Desktop Fail-safe". I've checked the list of start-up applications, but everything seems fine there. I can't yet put my finger on what exactly might be responsible for this: X, gnome or some messed up pam.d settings. So far I've checked /var/logs/X11/xorg.0.log, /var/logs/auth.log and ~/.xsession-errors. In addition, I don't quite seem to understand the "interplay" between X, GDM, GNOME, GNOME-policykit, PAM.d and all that. Are there any other relevant log files that could point me to what's broken?

• Is executing SQL through a WebService a really bad idea?

  - by Kyle

  Typically when creating a simple tool or something that has to use a database, I go through the fairly long process of first creating a webservice that connects to a database then creating methods on this webservice that do all the type of queries I need.. methods like List<Users> GetUsers() { ... } User GetUserByID(int id) { ... } //More Get/Update/Add/Delete methods Is it terrible design to simply make the webservice as secure as I can (not quite sure the way to do something like this yet) and just make a couple methods like this SqlDataReader RunQuery(string sql) { ... } void RunNonQuery(string sql) { ... } I would sorta be like exposing my database to the internet I suppose, which sounds bad but I'm not sure. I just feel like I waste so much time running everything through this webservice, there has to be a quicker yet safe way that doesn't involve my application connecting directly to the database (the application can't connect directly to database because the database isn't open to any connections but localhost, and where the appliction resides the standard sql ports are blocked anyway) Especially when I just need to run a few simple queries

• mouse and mousepad not working properly

  - by snake

  Ubuntu 12.04 LTS Samsung Q35 The mouse pad has stopped working, only the buttons work. The external mouse is also behaving very oddly, the mouse pointer works, but the button is not working properly, it has to be pressed many times or held down to select anything, and when anything that I select behaves as though the mouse is being clicked all the screen, settings will keep changing, the page will scroll, sliders will move up and down, tabs will toggle etc, so everything is unusable with the mouse, cannot even use the browser as it keeps scrolling the page up and down. I have tested the mouse on another computer, and it works fine. Please bear in mind that I am also a complete Linux novice, I installed Ubuntu on an old laptop for my kids, that is the limit of my experience.

• Can I upgrade Unity

  - by user208455

  Since the bug described here I am moving LTS distros only, however the current LTS is 12.04, and I`ve seen how ubuntu 13.10 looks like, I know that the unity interface is a WOP but, I wanna know is there any possible way to upgrade unity in 12.04? and btw, after that wipeout ,from the post I was reffering to, that sam stupid (to be polite) thing did windows xp, but now I have shortenned the 500GB ntfs partition to 100 GB and added a 100GB ubuntu partition (for /) and a 200+ GB partition for /home and installed ubuntu 12.04 like that (in "something else"). And after a few minor grub issues everything works perfectly, just like it should be

• Slow Wireless Reconnect After Suspend

  - by nrhine1

  I a Broadcom 4312 using the STA drivers, I reinstalled ubuntu because the b43 drivers were giving me a huge hassle along with some weird kernel issues. My wireless speed is fine, everything works well, except upon restart of computer and after taking the computer out of suspend. It takes about 30-45 seconds for the wireless to reconnect, and I think it is a driver issue (I clicked on the network manager at the top and for about 30 seconds there are no wireless networks listed.) I tried this advice already: http://lilserenity.wordpress.com/2007/10/31/fix-ubuntu-dropping-wireless-on-suspendhibernate-resume/ which basically says to change this: STOP_SERVICES="" to STOP_SERVICES="networking" in the file /etc/default/acpi-support This did not help anything. Something to note is that the issue does not occur when I am logging back in after already logging in once and logging out.

• ASUS X53S Intel Graphics and Unity 3D

  - by Nordlöw

  I just bought a ASUS X53S. Everything works flawlessly except that I can't run Unity 3D on it because NVIDIA Linux drivers currently doesn't support Optimus. So I'm stuck with the other integrated Intel Graphics Adapter. I'm already installed BumbleBee but it doesn't help with Unity 3D thing. Will the Xorg driver ever support OpenGL and especially GLX_texture_from_pixmap so that Unity 3D will work with it? The Intel driver is really snappy with Unity 2D and seems to support most other X acceleration features such as smooth scrolling.

• USB Mouse/Keyboard not working

  - by crstn

  I installed Ubuntu 11.10 after booting it from a USB drive. Everything worked fine there, after booting the keyboard worked in grub but not after Ubuntu was booted. I can unplug either of them and plug them in via a PS2/USB adapter and the device will work. After switching a couple of times, I got the keyboard and mouse both working via usb but after I rebooted either stopped working. How can I fix this? The mouse is a Razer Krait and the keyboard is a Logitech ClassicKeyboard 200.

• Environment font size is too small

  - by Adobe

  So I've chosen a font by System Settings - Application Appearance - Fonts And there I've adjusted all fonts to be of 14th size. And also checked "Use my KDE fonts..." in Gtk+ appearance. I've also did the same using kdesudo systemsettings But still some fonts are tiny! It's not the 14th size! Edit 2: I thought it might be one of Gnome font settings. So I've increased all fonts in gnome-tweak-tool sudo gnome-tweak-tool gconf-editor sudo gconf-editor No help! Edit: Ubuntu tweak also gives no help (note the tiny fonts!): Edit: It looks like the problem is with gtk3: when I compile emacs 24.0.92 with gtk3 - i get small menu fonts. When I do the same with a default gtk2 - everything is all right.

• I`ve got some problems with new Acer Aspire S3

  - by xcariba

  I just got a new Acer Aspire S3 Laptop, and I've installed Ubuntu on it. Here is some problems: 1. Bluetooth (AR3012) can't find any devices. rfkill shows that everything is fine, but I still can't connect to any device. (Maybe it was turned off in stock windows?) 2. Can't change screen brightness (I've tried Timex's solution with new 3.2-rc kernel and some grub options, touchpad works fine,but I still can`t use Fn+Right/Left) 3. 720p video in all players(VLC, mplayer and totem) works wrong. I found some similar problems on intel video chips with vblank sync or something like that. Video plays as it should, but i always see a line which appears on action scenes (looks like some parts of a screen updates faster) Maybe there are some solutions from similar laptops that I can find? PS I've tried ubuntu 11.04 with old kernel and linux mint 12-rc with 3.2-rc2 kernel.

• I removed Ubuntu from the BIOS menu but it comes back.

  - by jimirings

  For reasons too long to explain, I reluctantly removed Ubuntu from my computer. After completely removing it and deleting the partition that it was installed onto, I discovered that I still had two Ubuntu entries in the boot order in my BIOS menu. I deleted them by following the instructions in this answer: http://askubuntu.com/a/63613/54934 As I was doing it, everything appeared to go smoothly. However, upon reboot one of them came back. What's going on here? How do I delete it permanently? I'll gladly provide any other information that may be needed to diagnose the problem. Thanks.

• Game Asset Storage: Archive vs Individual files

  - by David Colson

  As I am in the process of creating a 3D c++ game and I was wondering what would be more beneficial when dealing with game assets with regards to storage. I have seen some games have a single asset file compressed with everything in it and other with lots of little compressed files. If I had lots of individual files I would not need to load a large file at once and use up memory but the code would have to go about file seeking when the level loads to find all the correct files needed. There is no file seeking needed when dealing with one large file, but again, what about all the assets not currently needed that would get loaded with the one file? I could also have an asset file for each level, but then how do I deal with shared assets This has been bothering me for a while so tell me what other advantages and disadvantages are there to either way of doing things.

• How to flag a class as under development in Java

  - by Usavich

  I'm working on a internship project, but I have to leave before I can finish up everything. I have 1 class that is not stable enough for production use. I want to mark/flag this class so that other people will not accidentally use it in production. I have already put the notice in Javadoc, but that doesn't seem enough. Some compiler error or warning would be better. The code is organized like this: [Package] | company.foo.bar.myproject |-- Class1.java |-- Class2.java |-- Class3.java <--(not stable) If there was a single factory class that calls those classes in public methods, I could have set the method to class3 as private. However the API is NOT exposed that way. Users will directly use those class, e.g. new Class1();, but I can't make a top-level class private. What's the best practice to deal with this situation?

• Titles in Google results contain spammy prefixes

  - by rfoote

  Over the past couple of weeks, we've noticed that the search results from Google for some of our drupal-powered sites are having their page titles hijacked somehow. An example would be: free streaming porn - [Actual page title] There are other variations of the porn prefix, that's one of the more tame ones. I looked in the databases for each of these sites and the titles haven't actually been changed or anything along those lines. When you click on the result to visit the page everything looks normal (sans porn stuff). Would anyone be able to point me in the right direction as to what the cause of this is?

• Lubuntu: How do I autostart xfce4 power manager?

  - by user203766

  I just upgraded my 64 bit Lubuntu to 13.10 on my netbook today. After the upgrade, I simply can't autostart the xfce4 power manager. I tried to add from the desktop session settings, I tried to copy the power manager.desktop file to ~/.config/autostart folder. Everything looks fine. Then I logout, log back in and the darn power manager just won't start automatically. It only starts when I double click the icon, or if I start it from the terminal.
