• How do I get my HP M1132 printer to work?

  - by Lucas

  I connected my printer to the computer and Ubuntu 12.04recognized it and installed it, but when I try to print something, the printer just gives a signal as if the document had already been printed and nothing happens, and at the printing queue the job is still there as "Processing - Not Connected?" or "Stopped". The printer is working fine on Microsoft Windows and I am sure it is connected. In the status field in the printer properties, it says: Processing - /usr/lib/cups/filter/hpcups failed. I'd like someone to please teach me how to get this printer (and it's scanner) working on Ubuntu.

• How to get the Dash and HUD to appear. (and stop Unity spewing error messages.)

  - by Ubuntiac

  I just installed Ubuntu 12.04 on my wifes Dell Inspiron 1501, which uses an R300 ATI graphics chip. Neither the Dash or HUD appear when pushing the appropriate key. When I try unity --reset & in the terminal, I see that over and over it's spitting out: r300: CS space validation failed. (not enough memory?) Skipping rendering. This is just after starting Ubuntu with no apps open, so I find it hard to believe that just rendering the Dash / HUD is completely blowing out the VRAM. Any suggestions on getting this working? /usr/lib/nux/unity_support_test -p shows OpenGL vendor string: X.Org R300 Project OpenGL renderer string: Gallium 0.4 on ATI RS480 OpenGL version string: 2.1 Mesa 8.0.2 Not software rendered: yes Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: yes GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: yes All sections say "YES"

• keep getting added to hosts.deny + iptables

  - by Sc0rian

  I am confused to why this has started to happen. On my local network, if I click 10-20 apache/http links my server will decide to add me hosts.deny file and block me on iptables. Its not just apache, it seems to happen with any kinda of traffic, that comes in on a flood method. Like I use subsonic, if I change tracks 10-20 times, it will do it. I would assume I have some sort of firewall which is sitting on the server which is doing this. However I do not have fail2ban or any denyhosts in /var/lib. I cannot work out why I keep getting added to hosts.deny/iptables. Thanks

• Tons of problems a new user is encountering

  - by Barney

  I've borrowed this laptop from a friend. I wanted to install AdBlock to boost performance. First weird thing was that even though I was on Chrome, Chrome suggested me installing him? So I tried to install ,than it gave me some message about broken dependencies. I Googled and tried to run those commands you guys were suggesting, but than it popped up error messages about everything again. Than I found out that some package called linux image generic is broken, than I tried to find an answer to that, but on the topic it was ” ndk.bhj\spo;ujvsdljvaEOYUFgidgAPIF;hsgvk in other words, I didn't understand anything about it, than there's this thing: E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? Seriously, when I'm trying to fix an error, there is another one. I'm on something called GNOME. Sooo, where do I start?

• Xubuntu all Icons disappeared

  - by user1392185

  I'm running Xubuntu 12.04.1 with kernel Xen4.1-amd64 and the following problem is mine: Nearly all icons have been replaced by the default "no icon available"-icon, even on the login screen and the all icons in software like e.g. Firefox and the icons I manually assigned to launchers, too. Changing the icon theme does not seem to affect this. The only icons that did not disappear are: LibreOffice, gThumb, Simplescan, Ristretto and in the XFCE menu office, tools and graphics. How could I bring the icons back? EDIT: When I tried to use Ristretto the following error showed up: Could not load image-loader module /usr/lib/x68_64-linux-gnu/gdk-pixbuf-2.0/2.12.0/loaders/libpixbufloader-png.so Unable to open shared-object-file I/O error (Had to translate this to English.)

• Motivation Problems, Middle School Programmer [closed]

  - by Anonymous

  I'm in middle school at the moment and have been programming for about a year and a half. I mostly work with Python and Ruby, and am currently learning Rails. I know, you can never learn enough, it takes a looong time to master a subject, but I feel like I don't have much left to learn :(. I've learned many concepts in Python, learned basically the whole std lib and have written a ton of programs, same with Ruby. In Ruby I've also done a lot of metaprogramming. After I've learned all the concepts, and written a lot of programs, there is nothing really left for me to do! What can I do, now that I've learned all the concepts, and written some programs? I can't get a job working with real developers, and the programming camp I went to last year was far too easy.

• HIB Games (Aquaria & Penumbra) cannot find libGL.so.1 even though it exists

  - by aberration

  I'm try to play some Humble Indie Bundle (HIB) games, but I'm getting errors with Aquaria and Penumbra: Overture that are related to the libGL.so.1 file. Aquaria gives this error on launch: Message: SDL_GL_LoadLibrary Error: Failed loading libGL.so.1 And Penumbra: Overture gives this error on launch: ./penumbra.bin: error while loading shared libraries: libGL.so.1: cannot open shared object file: No such file or directory I know that the file libGL.so.1 does exist (in /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1). From past errors like this, I'm guessing that you need to symlink the library to another directory, but I can't figure out which one.

• Ubuntu boots into terminal

  - by DKuntz2

  When I turn on my computer (a CR-48), I keep loading tty1. I have tried xstart, and all I get is: Fatal server error: Could not create lock file in /tmp/.tX0-lock When I attempted to make the directory (both sudo and not), I received these two errors: sudo: Can't open /var/lib/sudo/don/tty2: Read-only file system (I've gotten other tty's for different virtual terminals) mkdir: cannot create directory '/tmp/tX0-lock': Read-only file system Before I got to the only terminal state, I had the computer moving a few files from a network server to the computer, I put it to sleep without stopping the transfers, and started the computer again away from my home network, and attempted to stop the transfers, the computer than restarted. Running sudo reboot puts me right back in the virtual terminal, and I can't get into any sort of x application.

• Do I need any additional Java packages if I'm running the Oracle JRE?

  - by George Gorski

  I am running the Java 7 JRE from Oracle. I installed it through terminal and it works properly with my web browsers, and otherwise, as far as I can tell. However, I was browsing through my installed packages in Software Center, and noticed that both the 'openjdk-7-jre-lib' and 'openjdk-7-jre-headless' packages were still installed from when I had the OpenJKD JRE installed, which I have since uninstalled, but did use for a good period of time before I switched. Should those be there, or might they cause complications if I leave them installed? Or would it be best to leave them installed?

• Can't install ATI proprietary drivers in 12.10. Unity is Missing

  - by EApubs

  I have a laptop with ATI Radeon 6770M HD Hybrid graphics card. In Ubuntu 12.04, I installed the fglrx driver through "additional drivers" and it worked. (I can even switch GPUs). But in the new Ubuntu 12.10, after installing, Unity won't load. Only the mouse and the wallpaper. If I initialize the settings sudo aticonfig --initial then after rebooting it gives a warning saying I'm in low graphics mode! How to fix this? PS : Earlier i used software source to install the drivers. But when using the terminal, I got this warning : update-alternatives: warning: forcing reinstallation of alternative /usr/lib/fglrx/ld.so.conf because link group x86_64-linux-gnu_gl_conf is broken Update : Filed a bug report in launchpad : https://bugs.launchpad.net/fglrx/+bug/1068661

• Is avoiding the private access specifier in PHP justified?

  - by Tifa

  I come from a Java background and I have been working with PHP for almost a year now. I have worked with WordPress, Zend and currently I'm using CakePHP. I was going through Cake's lib and I couldn't help notice that Cake goes a long way avoiding the "private" access specifier. Cake says Try to avoid private methods or variables, though, in favor of protected ones. The latter can be accessed or modified by subclasses, whereas private ones prevent extension or re-use. in this tutorial. Why does Cake overly shun the "private" access specifier while good OO design encourages its use i.e to apply the most restrictive visibility for a class member that is not intended to be part of its exported API? I'm willing to believe that "private" functions are difficult test, but is rest of the convention justified outside Cake? or perhaps it's just a Cake convention of OO design geared towards extensibility at the expense of being a stickler for stringent (or traditional?) OO design?

• Why ~/.bash_profile is not getting sourced when opening a terminal in Ubuntu 11.04?

  - by Viriato

  Problem I have an Ubuntu 11.04 Virtual Machine and I wanted to set up my Java development environment. I did as follows sudo apt-get install openjdk-6-jdk Added the following entries to ~/.bash_profile export JAVA_HOME=/usr/lib/jvm/java-6-openjdk export PATH=$PATH:$JAVA_HOME/bin Save the changes and exit Open up a terminal again and typed the following echo $JAVA_HOME (blank) echo $PATH (displayed, but not the JAVA_HOME value) Nothing happened, like if the export of JAVA_HOME and it's addition to the PATH were never done. Solution I had to go to ~/.bashrc and add the following entry towards the end of file #Source bash_profile to set JAVA_HOME and add it to the PATH because for some reason is not being picked up . ~/.bash_profile Questions Why did I have to do that? I thought bash_profile, bash_login or profile in absence of those two get executed first before bashrc. Was in this case my terminal a non-login shell? If so, why when doing su after the terminal and putting the password it did not execute profile where I had also set the exports mentioned above?

• Distributing a very simple application

  - by vanna

  I have a very simple working console application written in C++ linked with a light static library. It is just for testing purposes. Now that the coding part is done, I would like to know the process of actually distributing the program. I wrote a very basic CMakeLists.txt that create makefiles or VS projects to build the sources. I also have a program that calls the static library in order to make some google tests. To me, the distribution of this application goes like this : to developpers : the src directory with the CMakeLists.txt file (multi-platform distribution) with a README.txt and an INSTALL.txt to users : the executable and a README.txt on my git repo : everything mentionned above plus the sources for testing and the gtest external lib A this point : considering the complexity of my application, am I doing it right ? Is there any reference that would formalize this distribution process so I can get better and go further ? Say I would like to add dynamic libraries that can be updated, external libraries like boost : how should I package this to distribute it in a professionnal way ?

• Dependency problem while missing package is already installed

  - by hakermania

  I am trying to install a program but I am getting a dependency error. The error clearly points out: Dependency is not satisfiable: libc6-amd64 (>= 2.14) I went on to investigate and I found out that I have 2.19 version installed, actually: alex@MaD-pc:~$ apt-cache policy libc6-amd64 libc6-amd64:i386: Installed: 2.19-0ubuntu6 Candidate: 2.19-0ubuntu6 Version table: *** 2.19-0ubuntu6 0 500 http://us.archive.ubuntu.com/ubuntu/ trusty/main i386 Packages 100 /var/lib/dpkg/status Why am I getting this error if I already have this package? I also should probably mention that the system is 100% up to date. I run the updates and upgrades, restarted the system and then tried to install the package again with the same error popping up. Edit 1: I am using amd64 but I have installed some 32-bit libraries required by some program installed via wine if I recall correctly.
