• HP dv2700 series, Wifi not working in Ubuntu 12.10, Wifi Button always disabled

  - by Chicoscience

  I have a HP dv2745se laptop. I always had Ubuntu with the Native Windows Vista and Wifi worked fine. Suddenly my Ubuntu wouldn't load anymore, I tried fixing it for a week and eventually I formatted its partition and just installed Ubuntu 12.10 This laptop has a Wifi switch that works fine in Vista disabling / enabling the wireless connection. HP Wireless Assistant in Windows say Wireless is on. However, whenever I log in Ubuntu the Wifi button is always orange (disabled) and Wireless never works. I had this problem once when I had Ubuntu 12.04 and I fixed it by verifying in Windows that the Wireless Assistant showed the Wireless LAN in "On" mode. However, the same does not work now. I've seen some possible solutions that involve updating the firmware with apt-get. There comes my 2nd problem, my network adapter card is not working and thus I have no internet at all. Any suggestions? Thanks!

• How to reduce noise in Skype?

  - by tkc

  According to Alsamixer I do have a HDA Intel soundcard with Nvidia MCP77/78 HDMI chip (Realtek sound card on MSI notebook). When I use Skype under Ubuntu 12.04 for video calls, the other side hears background noise such as in Windows when you have your microphone boosted. In fact they can hear everything, even the fans turning on. There is nothing tweaked on Ubuntu's fresh installation. Also tried this site: https://code.launchpad.net/~ubuntu-audio-dev/+archive/alsa-daily/+packages , but there are no *.deb files that I can test if any fix the problem. The question is if there is a way to add/tweak something to enable on software level the noise cancellation like the Windows sound drivers have that option. I use my build in mic.

• Ethernet Wired Connection Help

  - by user107598

  I have recently installed Ubuntu 12.10 onto my Dell Inspiron N5010 and Ive been all over many forums trying to figure out how I can get my ethernet cable to be recognized so I can set up a wired connection. My Network Card is the Realtek RT8139 and from what Ive gathered the ethernet port driver for it is installed. Whenever I run ifconfig in the terminal it says that eth1 is up and running but no matter how I edit the connection I cannot get it to work. If anyone can help it would be greatly appreciated!

• Ubuntu 12.04, Intel Centrino 1030 Wireless-N 1030 not able to connect to wireless

  - by playcat

  I saw several similar threads, but none really does it... I have 12.04 precise x64 installed and things worked great for some 10 days. Then it all stopped - I wasn't able to connect any more. Even more, things were so scre*ed up that it were showing other network's name while connecting :( I have an Asus K53SM-SX054. Here's the text from dmesg related to my card: http://fixee.org/paste/iaw23iw/ Basically, it's Intel Centrino Wireless-N 1030. Not sure if it's important, I had Gnome with unity and then moved to KDE. Any ideas what to do? I'm on the verge of reinstalling things, but I already set plenty of things and have some things that I'd need to back up... and I'm rather lazy to go on with it :) EDIT: My wlan network is hidden. Not sure if this should have any influence.

• Problem with NVIDIA G86 on Kubuntu 12.04

  - by Stefan

  I got problems some weeks ago with my NVIDIA G86 (8500 GT), supposedly due to the infamous 295.40 version of the driver. I got errror messges like NVRM: RmInitAdpterFailed. Tried varous sugestions about setting kernel acpi and memory options, but no luck. I pulled in x-swat and got 302.17, if I remember correctly. It did not help. People recommended xorg-edgers , so I pulled that in and got kernel 3.5.0.12 and nvidia 304.43 but the problem remained. Getting slightly panicked, I tried to back back to vanilla 12.04, so I purged nvidia* and located and removed anything on the system that smelled nvidia. I installed nouveau, cause people said it was great, but as it turns out, my card does not seem to be supported. :-( Sigh... So now I fear that I have atmessed up system, and graphics is terrible. Any help would be appreciated. Xorg.0.log: http://paste.ubuntu.com/1189616/ kern.log: http://paste.ubuntu.com/1189634/

• How to install Radeon Open Source Driver in Ubuntu 12.04

  - by Clintonio

  I have an MSI Radeon HD 7850 card. MSI provide no Linux support, and the AMD driver gives me an Unsupported Hardware watermark that does not show up in screenshots. I uninstalled the proprietary driver and found that Unity 3D no longer works, and I really only picked Ubuntu because of the excellent shortcuts provided in the recent versions. Trying to locate the open source driver has been a pain for me. According to the documentation I have read it is pre-included in Ubuntu 12.04, yet there is no Unity 3D support. I tried using the newest drivers from AMD's website, but that also had the watermark. Does anyone know how I can get the open source driver? If not, does anyone know how to remove the watermark. I'm on the verge of going back to Windows.

• Vmware 3D Acceleration Ubuntu 14.04

  - by Bowser5543

  I have installed Vmware Player 6.0.3 build-1895310. The problem I have is that when I run a Windows 7 Vm, it says that 3D support was disabled. (I can't read the exact report atm because it has a chance of crashing my machine.) I have the 3D support box enabled. Here is my graphics card: Mobile Intel® GM45 Express Chipset x86/MMX/SSE2. Can anyone tell me to install drivers or something? I can't find mine anywhere!

• Is it really a security problem to have non secure assets on an ssl page?

  - by blockhead

  My understanding is that this is just an example of being overly cautious, but if my checkout form contains an unsecure asset on it, that doesn't endanger anybody's credit card numbers from being caught by a man-in-the-middle. I'm asking this because every once in while, maybe because of cached content or whatnot, somebody writes in saying that they are seeing this "error" (even though there are no unsecure assets on my page), but they want an explanation. So yes, I can tell all about encryption and certificates and trust and men-in-the-middle. But what do I tell them about this. How do I convince them that the site is 100% safe (and if it isn't let me know that I'm mistaken!)

• Has anyone got "Creative Soundblaster X-Fi Surround 5.1 Pro" - (usb Interface) installed?

  - by Vivek Sharma

  Has anyone tried this external usb sound blaster on ubuntu. http://us.store.creative.com/Sound-Blaster-XFi-Surround-5.1-Pro/M/B0044DEDCA.htm. I have bought M-Audio Bx5a deluxe Studio Monitors for my T61. I think the onboard Intel HD sound card will not do any justice to these speakers. So I am looking for an external sound interface. I particularly liked this one as it is not very expensive and it has a volume control (speaker lack a central-front volume knob). Has anyone been able to use this on ubuntu. Also, if anyone would like to recommend me another option?

• 12.04 sound keeps auto-muting when idle

  - by fali

  I just installed 12.04 on an HP8510W. Everything works fine except for one weird behavior which I have noticed. When ever there is no audio playing, the audio mute indicator on the laptop is on. As soon as I start playing a you tube video the mute indicator turns off and I get sound. Here is my pulse audio output which says that the sink is suspended because it is idle: Welcome to PulseAudio! Use "help" for usage information. list-sinks 1 sink(s) available. index: 0 name: <alsa_output.pci-0000_00_1b.0.analog-stereo> driver: <module-alsa-card.c> flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY DYNAMIC_LATENCY state: SUSPENDED suspend cause: IDLE I tried running alsamixer, but I don't see the auto-mute option.

• How to add a command permanently to grub2

  - by tomodachi

  I have a fairly special setup, using Linux on a MacBook Laptop. to switch off my secondary graphics card in it I'm required to add these lines to my grub outb 0x728 1 outb 0x710 2 outb 0x740 2 outb 0x750 0 I do this by pressing 'e' for my selected grub menu option and adding the lines one by one . then finally booting . But as we know it's not permanent. I cant really figure out where i need to add it for grub to always append it to my Linux boot options. It's doesn't seem to belong in /etc/default/grub since here i can add stuff to the kernel boot line Honestly i'm afraid to fiddle to much with grub on my computer since getting it to triple boot Linux/Mac/Windows was a very delicate and timely matter. Does anyone have any idea of where to add it?

• Nvidia Fullscreen Metanode "Sliding" Issue

  - by user68202

  i have 2 monitors, the left one is my "main" monitor with 1920x1080_120, the right one my second with 1680x1050_60. (i have a nvidia card setup with twinview) when i play a game or something in fullscreen mode, the full resolution is used in fullscreen (monitor 1 + monitor 2). i read something about the metanodes i can use to shut down the one monitor that i dont need durning a "fullscreen session". i used the following: Option "metamodes" "DFP-0: 1920x1080_120 +0+0, DFP-2: 1680x1050_60 +1920+0; DFP: 1920x1080_120 +0+0, NULL" Its working great, the second (right) monitor is shutting down when i press "CTRL ALT +" and is starting agin when i press the same keystroke. But in the second mode when the second monitor is "down", i got the full "monitor 1 + monitor 2" resolution on my first (left) monitor, i can move my mouse to the right to see the contents of the second monitor and move it again to the left to the what is normally seen on the first monitor. Its something sliding between the 2 monitors on one display. How can i avoid this?

• 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

• play sound from different applications on different output devices (speakers, headphones)

  - by Mike

  I want music (played e.g. via Audacious) to be played on speaker system, and all other sounds produced by other applications (including ubuntu sound effects) to be played on headphones. My computer has sound connectors at its back, and also connectors on its front panel. When I connect both headphones and speakers, only headphones work (I take it, the front connectors take precedence?). Should I purchase another sound card (in addition to the motherboard-integrated sound I have)? When I go to Audacious output settings, I see only the ouput plugin selection list, with PulseAudio selected and options like ALSA, OSS4 etc. But there's no facility to select particular output device (and I guess it wouldn't magically appear even if I had the second soundcard). Is this at all possible to bind specific application to particular output device?

• Backtrack 5 R2 Dual-Boot w/Windows 7 No Longer Loads

  - by dstars5

  A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says: fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver Since it last worked, the only changes I can think of are that the computer is now connected via ethernet cable to the router, and I upgraded the graphics card (to nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me? Thanks!

• What's the difference or purpose of a file format like ELF when flat binaries take up less space and can do the same thing?

  - by Sinister Clock

  I will give a better description now. In Linux driver development you need to follow a specification using an ELF file format as a finalized executable, i.e., that right there is not flat, it has headers, entry fields, and is basically carrying more weight than just a flat binary with opcodes. What is the purpose or in-depth difference of a Linux ELF file for a driver to interact with the video hardware, and, say, a bare, flat x86 16-bit binary I write that makes use of emulated graphics mode on a graphics card and writes to memory(besides the fact that the Linux driver probably is specific to making full use of the hardware and not just the emulated, backwards compatible memory accessing scheme). To sum it up, what is a difference or purpose of a binary like ELF with different headers and settings and just a flat binary with the necessary opcodes/instructions/data to do the same thing, just without any specific format? Example: Windows uses PE, Mac uses Mach-O/PEF, Linux uses ELF/FATELF, Unix uses COFF. What do any of them really mean or designate if you can just go flat, especially with a device driver which is system software.

• Display monitor info via command line

  - by icyrock.com

  Is there a way to query monitor information from command line? For example, get monitor model, similar to e.g. what lspci does for graphic card info, or whether it's currently on or off, things like that. If possible, what kinds of basic information such as the above can be easily gathered? For example, is it possible to determine if monitor is in portrait or landscape position? Or if it has built-in speakers or not? Command line is the preference, but if there's a GUI method, I'd like to hear about it, too.

• How to test 3d acceleration?

  - by HappyDeveloper

  I want to install and test 3d acceleration in Ubuntu 12. I have read these pages: https://help.ubuntu.com/community/RadeonDriver https://wiki.ubuntu.com/X/Troubleshooting/VideoDriverDetection?action=show&redirect=X%2FTroubleshooting%2FFglrxInteferesWithRadeonDriver#Problem:_Need_to_purge_-fglrx I think I have installed it correctly, but I don't know how to test it. I tried to play minecraft in the browser, but I got a black screen. It may be a java problem too, so I need to troubleshoot. So how can I test my video card and drivers?

• Wireless not functional

  - by Michael Berkenblit

  I am a complete newcomer to Ubuntu. Today I installed Ubuntu 12.04 onto an 3 or 4 year old laptop - an HP DV2221. Install went fine, except that I can't get the wireless card to operate. I see that there are drivers installed (Broadcom STA wireless) and it says they are activated, but the wireless light on the body of the computer is lit as orange, when it should be blue, and if I disconnect the Ethernet wire, there is no ability to get onto Firefox. I've looked at some of the similar questions on this site, as well as Googling the issue - mostly, I guess I don't understand how to navigate or do some of the fixes recommended - I'm fairly adept technologically around Windows, but know zilch about Linux and how to perform some of the fixes - so, if possible, please tell me how I get to the menus needed to rectify the situation.

• Gnome Shell opens as classic

  - by Joe Horgan

  I'm running 12.04 on a Gateway LT4004u netbook, and I installed Gnome3 using the apt-get commands in the terminal. When I rebooted and ran "Gnome Shell" it opened up classic mode. I thought that my cursor might have slipped the first time, but on multiple retries logging in under gnome shell would open the gnome classic desktop. I even uninstalled Gnome Shell and reinstalled it with software center, but I still have the same problem. I was wondering if this might be an issue with my graphics card? Any help would be much appreciated, thanks! -Joe

• Problem with the screen resolution on 12.04

  - by sveinn

  I just installed Ubuntu on my laptop. The screen resolution is stuck in 1024x768. The screen is made for 1280x800. When I run xrandr I get: xrandr: Failed to get size of gamma for output default Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768 default connected 1024x768+0+0 0mm x 0mm 1024x768 61.0* 800x600 61.0 1280x800 isn't offered and I get gamma size error. I was going to look into the Xorg.conf file but I couldn't locate it. 1280x800 was displayed in Windows 7 and I think it is being displayed in Grub before Ubuntu starts also. Here are some details about my computer: CPU: Intel atom D2500 1.86GHz Chipset: Intel 945GSE+ICH7M LCD: 14" TFT 16:9 Resolution ratio: 1280*800 Video Card: Intel integrated GMA950 Does anyone know how to fix this?
