• OKI-B2540 printer doesn't print?

  - by NCLI

  There is a driver for the OKI-B2520, and it is automatically selected when the printer is connected. From looking at various websites, it seems like the B2500, B2520, and B2540 all work perfectly fine with the OKI-B2520 driver, so I let it install that. Everything went smoothly, the printer shows up as available, and I can queue jobs without any problems, and they disappear after a few seconds. However, nothing actually comes out. There is no error message on the printer display, or from Ubuntu. This is the output from the CUPS error log: http://pastebin.com/S6ifZAup So my question is: What is wrong??

• How to build list of items available in World of Warcraft?

  - by Cyclops

  There are a number of non-Blizzard sites that show a complete list of available items in World of Warcraft (such as wowhead, etc). I would like to know the best (easiest) way to compile a similar list. I believe some sites are based on user-entered input, which I would like to avoid. Looking at the lua API, it seems that there are functions to get a list of items, but it's not clear if I can just download everything (I remember a reference to throttling somewhere, can't find it now). Does anyone have code samples that would do this, or links to source? Also, Eve Online has made a database of items available (and I do mean SQL database file for download, not the Armory) - is there anything similar for Wow? I'm just looking for the names and stats, not the graphic icons.

• reading k&r(c book) and confusing 1st chapter code [closed]

  - by DarkEnergy

  #include <stdio.h> /* copy input to output; 2nd version*/ main() { int c; while ((c = getchar()) != EOF) putchar(c); } this is very confusing... since you never escape the while loop. I've learned that EOF is -1. i type -1 but it just reprints it. It's a never ending loop. Over time did the library get changed and differs from what the book intended it to be? when i say library i mean the putchar()/getchar() that's in the library... sorry.

• Ctrl-R Not Working in SSMS After a Patch?

  - by andyleonard

  I whined about this recently on Facebook. After that, I did something practical: I searched for a solution. I found a workaround at Connect : Open SSMS Select "Tools", "Customize..." - Click "Keyboard..." - In the list window, scroll down and select "Window.ShowResultsPane" - Under "Use new shortcut in:", select "SQL Query Editor" - Place your cursor in the "Press shortcut keys:" input area and press Ctrl+R - Click "Assign",...(read more)

• ALSA Mutes Incorrect Audio Device on Headphone Event

  - by Gardiner

  I know what the problem is, I just don't know how to prevent it. When I plug in my headphones, ALSA automatically mutes (and sets the volume to 0) the 'Speaker' entry in alsamixer. If I go in and manually unmute (and turn the volume up) I have sound from my headphones. Question is, how do I change this behavior? I want it to adjust the volume to half, but not mute or set the volume to 0. I'm using Ubuntu Gnome 13.04 Output of amixer scontents Simple mixer control 'IEC958',0 Capabilities: pswitch pswitch-joined penum Playback channels: Mono Mono: Playback [on] This answer solved my issue: How can I get sound on headphones without switching back to 'Speakers' manually?

• 12.10 sound resumes only after Suspend

  - by user70716

  I installed the 12.10 yesterday and like 12.04 there was no sound, I have an ACER 4830 TG. I noticed that the HDMI output is working fine, but Speaker or Headphone isn't working. So I did the following: sudo add-apt-repository ppa:ubuntu-audio-dev sudo apt-get update sudo apt-get dist-upgrade and still couldn't get the sound. Then I found the temp fix for this issue which is to Suspend the machine completely and resume. However, after restart the same thing happens. Is there a solution to this issue?

What other flags are there? How to read the flags? (because the explanation is quite complicated, IMO) Thanks.

• Tell the CDI 2 Expert Group What You Think!

  - by reza_rahman

  Since it's introduction in Java EE 6, CDI has become a key API for the platform. CDI 1.1 was a relatively minor release included in Java EE 7 as was CDI 1.2 (to be included in GlassFish 4.0.1). We have much higher expectations from CDI 2 (projected to be included in Java EE 8) under the new leadership of Antoine Sabot-Durand. Much like we conducted the Java EE 8 survey to solidify future direction for the platform, CDI 2 is now undergoing the same effort. Towards this goal the CDI 2 leadership is now soliciting feedback on some very specific items via an open survey. Topics include the likes of Java SE bootstrap, asynchronous processing, modularity, EJB-style @Startup and @Asynchronous in CDI, configuration and CDI Lite. You can of course also provide free-form input on anything that's not on the survey. Take the survey now on the CDI specification site and help shape the future of CDI 2 and Java EE 8!

• How to install Radeon X600 driver

  - by mmrs151

  I am completely new to Ubuntu and now running into so many problems regarding my display. I will be so grateful to the community to help me out and keep me loving Ubuntu. When I run lspci | grep VGA I get the following output 01:00.0 VGA compatible controller: ATI Technologies Inc RV380 [Radeon X600 (PCIE)] I am not sure if it means the driver is installed. Now the problem is I can not change the resolution like I can do in windows. I wanted to use dual monitor but it can not detect dual monitor. The monitor option in the preference shows 'Unknown' I tried to use a VGA switch for my ps3 and computer, but the computer is stuck with 1024x768 resolution. I have been trying for last three days, couldn't figure out anything. Now asking for you wisdom to get my display work. Regards, MMRAHMAN

• Sense of "stop on..." stanza when job is a task

  - by Binarus

  Hi, an upstart question (I think I have read all relevant man pages but could not find the answer there): What is the sense of using a "stop on ..." stanza in the definition of a job which is a task? The manuals tell us that such a job, after being started, just waits until its script (or exec stanza) is executed completely, and then stops automatically. Given that, what is the point in using "stop on ..." stanzas in such job definitions? For example, this is the job definition for Upstart's (very important) rc job in Natty 11.04 (leaving out comments and empty lines): start on runlevel [0123456] stop on runlevel [!$RUNLEVEL] export RUNLEVEL export PREVLEVEL console output env INIT_VERBOSE task exec /etc/init.d/rc $RUNLEVEL IMHO, the job, after being started by a runlevel event, will be stopped automatically as soon as /etc/init.d/rc $RUNLEVEL has finished. Thank you very much for any explanation!

• How do I check whether partitions on my SSD are properly aligned?

  - by elementz

  I just installed ubuntu on my new intel SSD. Now I am not sure, whether paritions are properly aligned in respect to my specific SSD. Here's my fdisk output. $ fdisk -l Platte /dev/sda: 120.0 GByte, 120034123776 Byte 255 Köpfe, 63 Sektoren/Spur, 14593 Zylinder Einheiten = Zylinder von 16065 × 512 = 8225280 Bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000a6294 Gerät boot.

If it is the case, that my partitions are not properly aligned, what could I do to fix this without having to reinstall everything?

• Triple monitors on hybrid video system GeForce+Intel

  - by v_mil

  I use Lenovo Ideapad Z580A with hybrid video: GeForce+Intel with Ubuntu 12.10 x64 Ukrainian. It has internal display and two outputs: HDMI and VGA. When I connect third display to VGA all displays go black. Pressing alt+backspace and login causes output to two displays: internal and VGA. System Settings - Displays (or monitors - I have Ukrainian interface) shows three displays: two are on, one (DVI) is off. Turning DVI on and pressing apply causes an error: Can not set configuration of controller CRTC 65. BIOS setting is Optimus (two video cards). Driver for GeForce is Nouveau. With best regards. Viktor.

• Why can't I access hw:1,0 until gstreamer-properties is run once?

  - by Shadd

  Not necessarily an Ubuntu-specific question but I wasn't sure where else to ask. I have an AverMedia DVD EZMaker 7 which plugs into USB and works well on Ubuntu 12.04. I downloaded and installed the official drivers without error. However, when I try: gst-launch alsasrc device="hw:1,0" ! alsasink device="hw:0,0" it tells me: Setting pipeline to PAUSED ... Pipeline is live and does not need PREROLL ... Setting pipeline to PLAYING ... New clock: GstAudioSrcClock which is the normal output, however there is no audible sound. Trying the command again doesn't help. If I run gstreamer-properties and close it right away (don't need to touch any controls), THEN the gst-launch command works. If I unplug the device and plug it back in or restart the computer, I have to run gstreamer-properties again. What is gstreamer-properties doing that enables the audio?

• My boss decided to add a "person to blame" field to every bug report. How can I convince him that it's a bad idea?

  - by MK_Dev

  In one of the latest "WTF" moves, my boss decided that adding a "Person To Blame" field to our bug tracking template will increase accountability (although we already have a way of tying bugs to features/stories). My arguments that this will decrease morale, increase finger-pointing and would not account for missing/misunderstood features reported as bug have gone unheard. What are some other strong arguments against this practice that I can use? Is there any writing on this topic that I can share with the team and the boss? I find this sort of culture unacceptable to work in but want to try and change it before jumping ship. Any input is appreciated.

• Help! Installer crashing

  - by Mike

  I had ubuntu 12.04 installed on a Satellite l635. I wanted to start over with a fresh install because I had experimented with a bunch of different things, and computer was getting glitchy and random freezes. I used the same iso I used for original install, and it keeps say the installer crashed with a erron5 input/output error. Tried an older iso for 11.10 I had used in the past with same issue... To see if it was disc or computer (not a great idea) I tried the 12.04 iso on another laptop. Now I have 2 laptops with no os. Both discs however live boot on both systems. PLEASE HELP! I've searched forums and can't find the same problem.

• Radeon HD5570 HDMI Video Card 5.1 Audio doesn't work

  - by ryandlf

  I am using Ubuntu and XMBC on my HTPC and have chosen the Radeon HD5570 Video card which has an HDMI output. In the sound preferences there is no surround sound option for the video card just stereo and although I can get sound through it in XBMC, my receiver does not state Dolby Digital on movies that are in fact Dolby so its definitely not giving me the true sound it should. Does this card not support surround sound through HDMI and I somehow missed it? If that is the case does anyone have suggestion that has been tested and works? Id like to know its going to work before investing in yet another video card. UPDATE I purchased a Nvidia GeForce GTS 450, plugged it in, downloaded the proprietary driver from the system control panel, disabled the onboard audio from the BIOS (not sure if this was necessary but I did it anyways), and changed the sound settings to use the new video card. Everything works flawlessly. It was a seemless setup.

  Before the update (I was using 13.04), editing: sudo gedit /etc/default/locale so that LC_TIME="en_GB.UTF-8" does the job. However in 13.10, this does not work anymore. I've tried editing: sudo gedit /usr/share/i18n/locales/en_AU sudo gedit /usr/share/i18n/locales/en_GB sudo gedit /usr/share/i18n/locales/en_US so that first_weekday 2 in each of the files, but this also does not work.

• W520 External monitor setup with Ubuntu 12.10

  - by user108372

  I just installed a fresh Ubuntu 12.10 64-Bit Desktop on my Lenovo W520. It looks like there are a lot of challenges around making it work with out of the box Nouveau drivers or propriety Nvidia drivers or Intel GPU. I looked at couple of notes on how to make it work with Bumblebee with Optimus Nvidia. None of them seems to work for 12.10. Anybody has a solid answer on this? It seems like a lot of people are suffering from this. Here is my xrandr output. Let me know if you need any additional information. Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192 LVDS1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm 1920x1080 60.0*+ 59.9 50.0 1680x1050 60.0 59.9 1600x1024 60.2 1400x1050 60.0 1280x1024 60.0 1440x900 59.9 1280x960 60.0 1360x768 59.8 60.0 1152x864 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) Thanks, Sef

• Interface design where functions need to be called in a specific sequence

  - by Vorac

  The task is to configure a piece of hardware within the device, according to some input specification. This should be achieved as follows: 1) Collect the configuration information. This can happen at different times and places. For example, module A and module B can both request (at different times) some resources from my module. Those 'resources' are actually what the configuration is. 2) After it is clear that no more requests are going to be realized, a startup command, giving a summary of the requested resources, needs to be sent to the hardware. 3) Only after that, can (and must) detailed configuration of said resources be done. 4) Also, only after 2), can (and must) routing of selected resources to the declared callers be done. A common cause for bugs, even for me, who wrote the thing, is mistaking this order. What naming conventions, designs or mechanisms can I employ to make the interface usable by someone who sees the code for the first time?

• Upgrading Ubuntu to 12.04 stuck

  - by Chris Britt

  While upgrading from 11.10 to 12.04, I'm stalled at the step: Installing new version of config file /etc/init/udevtrigger.conf The Terminal in the Distribution Upgrade window is expanded, there is no prompt for user input. I've hit enter a few times but it doesn't change anything but add a blank line after the last print statement. It's been sitting for ~6 hours at this stage. No other windows or dialog boxes are open. The upgrade has progressed through "Preparing to Upgrade", "Setting new software channels", and "Getting new packages". Under the progress bar (which estimates 1 day 2 hours remaining, and has for some time), it says Preparing to configure libpcap0.8. I'd take a screen-shot, but it won't let me save the file anywhere. The progress bar is about 1/3 complete.

• Why is Web SQL database deprecated?

  - by user221287

  I am making a hybrid Android app. At first I decided to use localStorage, after spending 2 days, I realized that it is very strange and so dropped it. Then, I picked up indexedDB, after spending today's whole day and actually getting the output in Google Chrome, it is not running inside a WebView of the android app. And I never used Web SQL database at all because it was deprecated. Anyhow, it has come to my notice that PhoneGap still uses Web SQL and android's browsers support it. Why was Web SQL deprecated in the first place? And will it be a good idea for me to go with Web SQL now?
