• No bass from the speakers

  - by Bhavesh Jogadia

  In Ubuntu 11.10 no bass sound at all when try to play mp3 or 2channels audio. I have 5.1/6 channels speakers. When I test speakers from the sound preference it works perfectly fine and then I try to play any MP3 there is no bass only the speakers work, I play 5.1 movies it plays fine bass sounds good. Also tried to to some changes as instructed with deamon.conf file but no go... When I turn my speakers on play speakers only mode it plays the bass but sound quality is not good compared to normal playing. I have a Creative 5.1 vx ca0160 sound card. In Windows also had the same problem unless I do bass redirection crossover frequency so is there any kinda software package or any kinda changes i can make in system file so that my speaker bass works fine or any thing who can let me change the bass redirection crossover frequency?

• Hard-copy approaches to time tracking

  - by STW

  I have a problem: I suck at tracking time-on-task for specific feature/defects/etc while coding them. I tend to jump between tasks a fair bit (partly due to the inherit juggling required by professional software development, partly due to my personal tendancy to focus on the code itself and not the business process around code). My personal preference is for a hard-copy system. Even with gabillions of pixels of real-estate on-screen I find it terribly distracting to keep a tracking window convienient; either I forget about it or it gets in my ways. So, looking for suggestions on time-tracking. My only requirement is a simple system to track start/stop times per task. I've considered going as far as buying a time-clock and giving each ticket a dedicated time-card. When I start working on it, punch-in; when done working, punch-out.

• What kind of screen has the best image quality for reading/programming?

  - by EpsilonVector

  I'm thinking about buying a new laptop, and while I bought my original one oblivious to the fact that there could be different quality screens out there, after seeing the screen on my sister's netbook I realized that I might have to be cautious with my next purchase. Granted, I did not confirm that the reason my sister's screen looks the way it does is due to the screen itself and not color scheme/graphics card, but I know very little about the different screen technologies and how they differ in image quality and therefore can't really tell if wondering about it even makes sense or not. So what I'm asking is: should I be worried about screen quality? And if so, what technologies should I be looking for? How do they differ and which are the best ones? What are the different elements that determine the quality of a screen and which stats should I go for in each element? For the record, I'm not interested in opinions about screen size, but picture quality for lots of reading/coding.

• ATI Proprietary Driver Over/Underscan setting ignored after reboot

  - by Lassi

  I installed the proprietary driver (fglrx-updates) on Ubuntu 12.10 64-bit for my graphics card (ATI Radeon HD 7570). I am using two displays, one connected with DVI, one with HDMI. I set the desktop to be expanded to both screens and disabled the under scan for the HDMI screen, which is always for some reason enabled on HDMI screens. Now the issue. Everything was fine until I restarted my computer. After reboot, the screen connected with HDMI cable had the black borders again, meaning that the under scan is again enabled. I checked the ATI CCC, and under scan was disabled. However, moving the slider to enable under scan and then back to zero fixed the issue -- temporarily. The same issue is repeated every time I restart my computer. The settings remains the same, but the computer seems to ignore it. Any ideas how I could solve the issue?

• Vdpau performance in Precise with Unity 3d

  - by bowser

  vdpau seems to be broken in Precise under Unity 3d. CPU usage ranges around 50-70% for 1080p movies while same movies utilizes around 5-10% in Natty with vdpau enabled (under Unity3d) The card is Nvidia G105m. It doesn't seem to be a Nvidia driver problem because in gnome-shell everything works as expected and I have tried different versions of Nvidia drivers (295.20, 295.33, 295.40 and the latest 302.XX from xorg-edgers) The results are all the same, works in Gnome Shell but not in Unity 3d. Disabling syn to vbank works if movie is not in full screen mode, but it doesn't work for full screen. I have searched around and haven't found much info. I am wondering if others are experiencing the same problem and if there are some known work around that I have missed. Unity 3d is otherwise very nice in Precise, but this is a show stopping issue for me (literally). Thanks. I have filed a bug here https://bugs.launchpad.net/unity/+bug/993397

• Grub-Efi wrong resolution

  - by Nikki Kononov

  My question, as it comes from the title, related to grub, but it's a different thing. I re-installed Windows 7 and Ubuntu 12.10 in UEFI mode (before that I was using normal BIOS) and everything went perfectly fine. Both systems load as they should but there is one thing that keeps bothering me. The problem is before I installed both systems in UEFI I used to boot in both system using common grub (non-uefi) and resolution in this grub was correct (which is 1366x768). Right now with grub-efi I have wrong resolution (which is seems to be 640x480). So my question is can can I safely set grub-resolution using grub config files or issue is related to something else? (for instance graphics card). I am using Ubuntu 12.10 Intel HD 3000 + Nvidia GT 540M Optimus (I am using bumblebee) Kernel 3.5.0-19-generic all updates installed! I also added ubuntu x-swat ppa for drivers. Thank you for your help!

• PIN request at each login after update to Maverick

  - by Giacomo Verticale

  I have a netbook with included 3G mobile broadband card (Huawei E620). I have configured the broadband network connection in the Network Manager and it works perfectly. However since Maverick upgrade, a window appears just after login I asking for the SIMcard PIN. This happens every time I log in and did not happen with Lucid. Note that the PIN is stored in the configuration of the mobile broadband connection and Lucid was satisfied with that. Is there a way to prevent this request or, at least, to have the system rember the PIN and stop ansking for it? If it may be useful, the broadband network connection is configured as not being available for other users. Also, I would like to keep the SIMcard asking for the PIN; only I do not want to insert it manually at login.

• Shotwell not available in 11.10

  - by John Speed

  I had used Shotwell happily previously then updated to Natty last week. Despite Shotwell showing on the tool bar on screen, when clicked, nothing happened, and it ignored my SD card when loaded. I read all sorts of remedies and tried everything to no avail. When I next turned on the laptop, Ocelot was available so with nothing to loose, I upgraded again. Still no Shotwell. Tried all the new fixes and now atleast I have the icon pictures but nothing behind it. When I ran the command to load the log file, Shotwell loaded and all my photos are present. Exited programme, and now nothing. Can anyone tell me where I have gone wrong please.

• Better drivers for SiS 650/740 integrated video?

  - by Bart van Heukelom

  I installed Xubuntu 10.10 on an old box today and the graphical performance is horrid. According to lspci, the video card is this: 01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter (prog-if 00 [VGA controller]) Subsystem: ASUSTeK Computer Inc. Device 8081 Flags: 66MHz, medium devsel, IRQ 11 BIST result: 00 Memory at f0000000 (32-bit, prefetchable) [size=128M] Memory at e7800000 (32-bit, non-prefetchable) [size=128K] I/O ports at d800 [size=128] Expansion ROM at <unassigned> [disabled] Capabilities: <access denied> Kernel modules: sisfb Is there a way to make it faster? Alternative drivers? The additional drivers tool shows nothing. I'm specifically interested in improving Java's Java2D rendering speed, because I'll be running a "stat screen" written in that language on it.

• Replace Broadcom "wl" driver with "b43"

  - by Laszlo Boros

  I'm using Ubuntu 10.04.4 LTS, and in my laptop there is a Broadcom BCM4312 wlan card. lspci output: 04:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g (rev 01) Subsystem: Broadcom Corporation Device 04b5 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at f4500000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [58] Vendor Specific Information Capabilities: [e8] Message Signalled Interrupts: Mask- 64bit+ Queue=0/0 Enable- Capabilities: [d0] Express Endpoint, MSI 00 Capabilities: [100] Advanced Error Reporting Capabilities: [13c] Virtual Channel Capabilities: [160] Device Serial Number 81-ac-1d-ff-ff-12-54-92 Capabilities: [16c] Power Budgeting Kernel driver in use: wl Kernel modules: wl, ssb So as you can see, the current (and default) driver is wl - installed with jockey. But I have another Ubuntu based distribution on my laptop (BackTrack linux), which is also 10.04, but it has the b43 driver installed and the overall performance is MUCH better. So I would like to install it on this OS too, but even google didn't help me. So my question is how to install the latest b43 driver on my Ubuntu?

• How To Specify Bitrate, Codec and Demultiplexing for VLC Video Capture or Recording

  - by Subhash

  I capture video from old TV tuner card - Pinnacle PCTV - using VLC. The video is from the Composite input and audio is from I guess the mixer or Line in. The command I use is: vlc v4l2:///dev/video0:normal=pal:width=720:height=576:input=1 :input-slave="alsa://hw:0,0" In VLC, I have enabled the Advanced Controls toolbar, which allows me to record videos when I want to. However, these videos are uncompressed - very big and play only with VLC. Totem throws the "Could not demultiplex stream" error. I need to convert them using WinFF to reduce their size and make them playable with Totem and other software. My question is whether I can configure the recording settings - the codecs and the bitrate, and also get the stream demultiplexed. If I pass any -sout parameter with command I get a "Segmentation fault". I use 64-bit Ubuntu 10.10.

• A certain flash application causes a system crash

  - by noobermin

  It's no surprise I guess. Go here to try it! http://www.belgeler.com/blg/2hni/griffiths-introduction-to-electrodynamics-3-ed-solutions-manual It's wonderful, after a few seconds, top shows that our good friend plugin-container takes 83% of the physical memory (8 GB) before everything freezes and the PC doesn't respond. I'm using Ubuntu 12.04 and I have an nvidia (GTS 250) card with the "post-release updates" version of the driver. OFFTOPIC: Yes, it's the solutions manual. I'm self-studying so I don't have a professor to check my work. Please don't judge me :)

• Emailing Interviewer after interview regarding technical solution

  - by Raghav Shankar

  I had an interview yesterday where I was given a programming problem and I was asked to figure the optimal solution for it. I gave a solution that worked in linear time, but used 2 loops (not inner loops). At the end of the interview, the interviewer saw I was interested in solving the problem, so he said the optimal solution uses only one loop and has linear complexity and at the end of the interview I had asked for his card and he gave one to me. I think I might have figured out a solution and I was wondering if it's alright to email the recruiter thanking him for his time and also mentioning about the solution I had figured out?

• How do I record audio through M-Audio Keystudio?

  - by interstar

  Hi, I'm trying to get my M-Audio Keystudio (which has an audio input as well as the keyboard) to record audio to Audacity. I'm in Ubuntu 10.10. When I look at the Sound Preferences I can select "M-Audio RunTime DFU Analog Stereo" as my input device. However, when I try to record in Audacity, Audacity remains frozen. The program seems to be running and recording, but the recording cursor won't advance. If I reset the audio input to the internal sound card, recording works normally. Any ideas what to look for?

• 12.04 Dual Monitor Configuration changes to "Mirrored" automatically

  - by Josef

  After installing 12.04 on my Samsung X120 Notebook (with Intel GMA 4500 internal graphics card) i have a Problem with the configuration off my 2nd monitor. Its a 22" with 1680 * 1050 Pixel connected via HDMI. I use the display configuration and set internal display=off and external display=main display. That works fine. After rebooting i still have that configuration, but after a while (often when i press a button on the keyboard), the configuration automatically changes to "Mirror Screen" and the internal display switches on. Both displays then have a bad resolution. When i do the manual display configuration again, everything is fine for the duration of that session. What could be the problem, that this display configuration gets lost / resets?

• Is it normal to not have desktop effects after installing on an Asus N53S?

  - by Fabzter

  I've just installed 11.10 and so far so great, except I just discovered (after looking at another installation) I'm missing some effects. First of all, I am using unity 3d (I chose ubuntu at the login menu), and have already the correct nvidia drivers. Yet, my launcher is the same from unity 2d, the same as the app switcher, and when dragging windows to screen corners, they don't get grabbed. This "error" was present since the begining, so I was not able to detect it. Please help, I want to have an ubuntu experience as nice as everyone else. EDIT 1: I'm using an Asus N53S. My graphic card is Nvidia geforce GT540M. It says cuda, if that matters.

• List of eCommerce sites that use end-to-end SSL?

  - by Jon Schneider

  My development team is considering implementing an eCommerce site using end-to-end SSL -- that is, every page on the site is accessed via an https:// URL -- rather than the more traditional "mixed mode" where most pages are accessed via http:// and only "secure" pages such as login and credit card entry are redirected to https://. Pros of doing such a "pure SSL" approach include avoidance of some session-hijacking attacks such as Firesheep; cons include performance considerations. My question is: Is anyone aware of a list of eCommerce websites (especially USA-based sites), or even specific websites, that use this end-to-end SSL approach? I'm especially interested in "regular" eCommerce sites rather than banks or other "financial" sites.

• Ubuntu 12.10 AMD/Intel Hybrid Graphics not working

  - by Marian Lux

  On Ubuntu 12.04 my Sony Vaio VPCSE with Intel® HD Graphics 3000 and AMD Radeon™ HD 6630M worked fine with the Catalyst Control Center version 12.6. Also the switching between integrated and discrete graphic card was working. In both cases, I followed this tutorial. But it is not working on Ubuntu 12.10. I tested the tutorial with the Catalyst Control Center from the Ubuntu Software Center, the version 12.8 and version 12.9. Always the same problem: After installation process I am able to boot in the login-screen. But after entering the password for my username, only the background-image appears. Unity seems not to be starting. I am only able to reach the context-menu by right clicking the mouse button. I also tried his fix, but is also does not work for me. Any ideas what to do to fix this problem?

• Sound Problem due to wrong driver installation

  - by Starx

  First of all, the audio used to play from the speaker but whenever I connected a headphone or speaker in the I, the sound didn't came. So I installed a realtek sound driver to fix this (actually I didn't find any relevant driver for my sound card so I installed it hoping it would show some light) When I rebooted the system, my sound is completely gone and now ubuntu does not detect any sound devices in my system. I clearly installed wrong driver, now I need to remove and go to previous stage and find a correct driver. My laptop is: Dell Studio 1747, uses a speaker Creative Labs Sound X-Fi MB Sound Blaster and the chipset is INTEL PM55. How can I fix this?

• NVIDIA 560 TI driver install ubuntu 14.04 leads to "missing on display" error

  - by allthosemiles

  Currently on my Ubuntu 14.04 install, I boot it up install the latest updates and attempt to install the NVIDIA drivers from xorg-edgers while following the top answer on this post Installing Nvidia Drivers It installs 304 for my card and when I check the "glxinfo | grep OpenGL" I have about 8 lines that read Xlib: extension "NV-GLX" missing on display ":0". I did the "sudo apt-get install nvidia-current" to get the latest. I install it but didn't see any errors in the terminal. I'm not sure what I'm doing wrong here. I'm not a complete beginner with Linux so I can find my way around just fine but I can't find a solution to this issue. Should I have done one of these two instead? sudo apt-get install nvidia-304 sudo apt-get install nvidia-graphics-drivers-304
