  • Video freezes when larger than a certain size

    - by Poyan
    I have a weird problem playing video files. I have a fairly new (a few years old) graphic card that should and has played up to 1080p video files without much a lot of trouble. I seem to be having a weird issue where the video plays back fine if the window is below a certain size, but as soon as the windowsize increases, the picture freezes. The audio still plays. Usually this is mitigated by killing som applications. Especially GTK (?) apps seem to cause this lag, like having a Nautilus window open usually triggers this error for me. With hardware rendering I get the error regardless of application. I have tried enabling software rendering in VLC and that eliminates the problem (but I get other problems using software rendering, so I've avoided it). I know this is pretty fuzzy, but I'm not sure how to approach this problem. Do you have any idea? EDIT: Some more information. I have the correct and latest drivers installed. My graphics card is a Nvidia 7600 GT.

  • Windows Physical Direct Memory Mapping

    - by chrisjleaf
    I'm a bit disappointed there is almost no discussion of this no matter where I look so I guess I'll have to ask. I'm writing a cross platform memory bench marking application which requires direct physical address mapping rather than virtual addressing. EDIT The solution would look something like the Linux/Unix system calls: int fd = open("/dev/mem", O_RDONLY); mmap(NULL, len, PROT_READ, MAP_SHARED, fd, PHYSICAL_ADDRESS_OFFSET); which will require the kernel to either give you a virtual page mapping to the desired physical address or return that it failed. This does require supervisor privileges but that is ok. I have seen a lot of information about shared memory and memory mapped files but all of these reside on disc and are thus not really useful when I'm trying to make a system dependent read. It is very similar to writing an IO driver although I do no need write permissions to the physical address. This site gives an example of how to do it on a driver level using the Windows Driver Kit: NT Insider: Sharing Memory between drivers and applications This solution would probably require Visual Studio which currently I do not have access to. (I have downloaded the WDK api but it complained about my use of GCC for Windows). I'm traditionally a Linux programmer so I'm hoping there might be something really simple I'm missing. Thanks in advance if you know something I don't!

  • iOS 5 New Features vs Android

    - by kerry
    Browsing through the iOS 5 features list, I can’t help but notice a lot of it is catch up. Having owned both an iPhone and an Android for a considerable amount of time, I figured I would jot down my opinions. Notification Center – Completely ripped off from Android but looks good and is a much needed addition iMessage – This is very interesting as most people who would think it’s cool, probably really wouldn’t understand the significance.  Basically, Apple is adding an IM application to iOS.  Now iPhone / iPad users can sit around messaging each other how cool it is like Crackberry users circa 2003.  I guess the only real improvement over MMS is that you can easily setup groups, see when each other are typing, and don’t incur text messaging charges; at the expense of leaving your non-iOS buddies out (who wants to talk to those losers anyways?). Newstand – An app update and not an OS one (Apple typically doesn’t make distinctions).  It all seems like stuff my current Nook stuff will do.  Note: I did look to compare prices but it seems that information is not available without downloading iTunes.  lame. Reminders – TODO lists are ho hum, but the ability to have reminders when you arrive or leave a position is pretty cool. Twitter integration – The fact that the best Apple can come up with is ‘one at a timing’ online service integration is laughable at best. Camera – Can control it from the lock screen.  Now you’ll have tons of pocket lint photos in your iCloud to go along with the wicked shot of that cheetah that just unexpectedly ran by your apartment. Photos – Speaking of iCloud, all of your devices photos will be synced through it.  That’s cool I guess, not sure if Android will do the same. Safari – What?  You haven’t been reading rss feeds on your device this whole time?  Something tells me you aren’t about to start. PC Free – Finely Apple untethers the iPhone.  What took them so long? Game Center – This should be an interesting service.  Attention Apple fanboys immediately forget how they are blatantly copying Microsoft achievements (at least rename them). Wifi Sync – Just couldn’t cut the cord completely could they?  For what it’s worth, the Zune has been doing this for 5 years now. All in all a pretty big update.  Mostly iCloud.  Mostly keeping up the mobile status quo.  As an Android user, I can’t say there is anything I am envious of.

  • X won't start, root filesystem mounted read only

    - by TK Kocheran
    I just experienced a very strange and puzzling problem on my machine that I can't seem to get sorted out. I was running Windows on a second partition, and everything was working great. I then went to restart into Linux, and noticed that X wouldn't start. Everything was displayed in super-low resolution, so I tried reinstalling my NVIDIA driver. I started seeing all of these I/O error problems, so I figured that my SSD was bad. After a bit more playing around, I ran fsck on the drive when mounted from a startup disk as well as badsectors and everything looked great. The SMART drive tests all passed and again, everything was looking good, so I rebooted again and still, no joy. I started then getting some weird USB errors, so I followed someone's advice and unplugged my computer's power supply, then started back up again and my graphics looked a lot better in the BIOS and in the boot logo, but X still wouldn't start. I then found out that my main boot drive was being mounted read-only for some reason. What's going wrong? I've done some pretty extensive tests on the SSD from a startup disk such as writing massive files, reading big files, running filesystem checks on the entire disk, and everything is looking great, until I try to boot. Whenever I try installing the drivers with apt-get, I get a ton of ata error messages looking like this: How can I diagnose what's going wrong and fix it so I can get back to work?

  • Can certain system-hungry modules be disabled in Ubuntu?

    - by Ole Thomsen Buus
    Hi, Let me add some context: I am currently using Ubuntu 9.10 64-bit (Desktop) on a relatively powerful stationary PC (Intel Core i7 920, 12GB ram). My purpose is highspeed imaging with a pointgrey Grashopper machine-vision camera (for research, PhD project). This camera is capable of 200 fps at full VGA (640x480) resolution. The camera is connected using Firewire (1394b) and the drivers and software from Pointgrey works great. I have developed a console C++ application that can grap a certain number of frames to preallocated memory and after this also save the grapped frames to harddrive. Currently it works fine but sometimes I am observing a few framedrops (1-3). When this happens I reset the experiment and repeat the recording and usually i am lucky the second time with no framedrops (the camera-driver has a internal framecounter that I am using). Question: I usually go to tty1 and use "sudo service gdm stop" to disable the graphical frontend. It seems to release some memory though that is not my main concern. My concern is CPU resources. Are there other system hungry modules that can be disabled temporarily such that the CPU gets less busy on Ubuntu 9.10? At some point in the future I will update to 10.10. Should I perhaps option for the server edition instead? Thanks.

  • Unity in 12.10 comes up behind other windows

    - by ams
    I've just upgraded from 12.04 to 12.10. For the most part, everything works fine, but I have a few small problems with Unity, or maybe Compiz. When I hit the Super key, or click on the dash launcher, the dash sometimes comes up behind the other windows on the screen. As you can imagine, this makes it somewhat tricky to use. Once it has started coming up behind, no amount of trying again will convince it to come back to the front. Possibly related, the Alt-Tab switcher doesn't show either. It maybe that there isn't one, or maybe that's behind also? Alt-Tab does switch the windows, but there's no visual indicator. When I hit Super-W, the windows do all do the zoom thing, but it's slow and juddery where it used to be smooth in 12.04. I'm using the standard "radeon" driver, same as before, with a triple-head monitor setup (and that works fine). I've not tried the proprietary drivers as I've previously found the multi-monitor support much weaker than the default driver, but maybe that's the way to go now? Video play fine. Even WebGL seems ok. Do other see this problem? Is it a bug? Or have I just got some left-over config from 12.04 in the way?

  • Wireless connection disconnects and reconnects with a Netgear WNA1000

    - by William Berkenkamp
    Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard.

  • Hardware issues on Samsung NF208 (NF210)

    - by KristoferA - Huagati.com
    I'm trying to get Ubuntu 10.10 running on my wife's Samsung NF208 (same spec as NF210, but shipped without OS), and I have run into a pile of problems: At first, there were problems with audio, display brightness, and WiFi, so I reinstalled Ubuntu from scratch. After reinstalling, the audio has started working but the WiFi loses network access all the time and then it takes 5-10 minutes for it to reconnect to the network. Also, display brightness is at its lowest. I have tried to use the brightness command but it won't run. Is this system utterly incompatible with Ubuntu, or are there working WiFi and display drivers for it somewhere? I have googled for days but haven't found anything useful. Help me. Update: I never got it working properly. I came across lots of useful tips and tricks over at the forum linked to in the accepted answer but I just wasn't able to get it working and stable enough for the intended use. Hopefully a future version of Ubuntu and/or the samsung tools will solve that. Related thread over at the other forum: http://www.voria.org/forum/viewtopic.php?f=3&t=682

  • Pantheon Not Completely Installed?

    - by Simon
    I have just installed the pantheon shell today, and I have not found any help with this yet. I am not just a random noob, i use a bunch of other shells and i also have a few development applications on my copy of ubuntu. But ever since ive opened up pantheon, i cannot find settings or this thing called the launchpad. (if the launchpad is the app drawer up in the upper left corner, or if its the dock. i have it, if thats not what launchpad is, then i cant access it.) I can only change my wallpaper by going back to unity, gnome, or KDE. There is a system settings in the power menu (upper right), but it only has Language Support, Ubuntu One, Additional Drivers, And Printing. I can still access the full ubuntu settings in GNOME of Unity. But thats it. I installed in the terminal, uninstalled, and reinstalled using the software center. Please Help Me If Any Of You Can! Thanks!!!

  • LiveCD/USB boot issues with Ubuntu 12.04 on blank drive

    - by Richek
    Not sure how common this issue is, or even how badly I may be missing something simple, but I am a first time usuer having some serious problems. Some background: old HDD running Windows 7 developed too many bad sectors and is bricked. I'm attempting to install Ubuntu 12.04 on a fresh 1TB drive by booting from a liveCD USB flash drive. I've not been able to get past the initial menu screen, however, as the process stalls out shortly after selecting an option (both boot from drive and install to drive). I've tried multiple USB drives as well as CDs, modified the boot order, flashed BIOS, and even tried booting with only the flash drive and the keyboard connected with the same results.Typically what I observe is that the OS begins what I think is compliling, listing drivers and components before freezing on one. When the keyboard is plugged in, its the keyboard driver, before I flashed BIOS, it was a BIOS related item, now its an unknown entry. The computer seems to be reading the drive (idicated by USB light flashing or CD drive reving) for roughly 10 minutes with no progress, followed by the drives going quiet. Some spec info: Motherboard: ASUS P5Q Pro, BIOS version 2102 (latest version), Intel chipset CPU: Intel Core 2 Duo E8400 Wolfdale 3.0GHz help would be appriciated!

  • Error: kernel headers not found. (But they are in place)

    - by Guandalino
    I'm trying to install the Guest Additions in VirtualBox 4.04. Host OS is Ubuntu desktop 11.04 64bit, guest OS is Ubuntu server 11.10 64bit. $ sudo ./VBoxLinuxAdditions.run After some output this line is printed: The headers for the current running kernel were not found. But the headers are installed, at least accordingly to dpkg: $ dpkg --get-selections | grep linux-headers linux-headers-3.0.0-12 install linux-headers-3.0.0-12-server install linux-headers-server install The running kernel is: $ uname -a Linux foobar 3.0.0-12-server #20-Ubuntu SMP Fri Oct 7 16:36:30 UTC 2011 x86_64 x86_64 X86_64 GNU/Linux How do I fix things so that Guest Additions installer is able to find kernel headers? Update: added full output. The headers for the current running kernel were not found. If the module compilation fails then this could be the reason. Building the main Guest Additions module ...done. Building the shared folder support module ...fail! (Look at /var/log/vboxadd-install.log to find out what went wrong) Installing the Window System drivers ...fails! (Could not find the X.Org or XFree86 Window System). I don't care for fail #2, because that's a server and I don't need X server. But I need shared folder support.

  • Dualboot (Win 8 / Ubuntu 13) is stuck at 'switching to clocksource'

    - by Daniel Puscht
    for days I have been crawling the web for solutions to my problem, but couln't find any. Here it is: I got a new Laptop (ASUS Vivobook S200E) with Win 8 OEM preinstalled. I wanted to create a dual-boot system with Ubuntu 13 next to it. I read about UEFI and that I have to turn of Secure Boot and use the existing EFI partition as bootloader for Ubuntu. So I did. I also ran boot-repair reinstalling the GRUB. The result is when I start the computer I get into the boot menu. So far, so good. When I pick Win everthing is fine. But when I choose Ubuntu (recovery) the system starts, but gets stuck at the line '[1.806366] Switching to clocksource tsc'. I already tried other versions of Ubuntu (12.04.2, 12.10). I played with boot-repair (using the recommended fix, setting everything manually). But nothing works. It's always the same issue. I read that it could be a problem concerning graphic drivers, but this I can hardly believe. If this is any help, boot-repair gave me this link to post in fora. http://paste.ubuntu.com/5810391/ Thanks for any help in advance

  • As a programmer, what's the most valuable non-English (human) language to learn?

    - by Andrew M
    I was thinking that with my developer skills, learning new languages like French, German etc. might be easier for me now. I could setup the verbs as objects in Python and use dir(verb) to find its methods, tenses and stuff ;-) But seriously, if you're a professional developer, in my case in the UK, what's the best foreign language to learn from an employment perspective? I'm thinking, like Hindi - if all our programming jobs are getting outsourced to India, might as well position yourself to be the on-site, go-between guy. Mandarin - if the Chinese become the pre-eminent economy, the new USA, in ten or twenty years, then speaking their language would open up a huge market to you. Russian - maybe another major up-and-comer, but already closer to Western standards. More IT-sector growth here than anywhere else in the coming years? Japanese - drivers of global technology, being able to speak their language could give you a big competitive advantage over other Westerners But I'm just guessing/musing with all these points. If you have an opinion, or even better, some evidence, I'd like to hear it. If the programming things falls through then at least it'll make for more interesting holidays.

  • Are Windows partitions gone?

    - by Gigili
    I had Windows 7 on my laptop (factory setting), because of some performance issues, I decided to use recovery options to restore it to its factory condition but I don't know what has happened or what I have done that the whole operating system was gone after playing around with recovery options from the boot menu. I couldn't find Windows, so I installed Ubuntu 11.04 on my laptop. Last time I had Ubuntu on it, it was not really compatible with laptop's configuration and I had a bit of problems trying to do normal tasks I used to do on Windows. Now I want to make sure that Windows and its drivers are gone so that I can try to install a newer version of Ubuntu or Windows. I tried the command sudo fdisk -l And the result shown was: myaccount@myaccount-VPCS116FG:~$ sudo fdisk -l [sudo] password for myaccount: Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00025b5f Device Boot Start End Blocks Id System /dev/sda1 * 1 38409 308515840 83 Linux /dev/sda2 38409 38914 4052993 5 Extended /dev/sda5 38409 38914 4052992 82 Linux swap / Solaris Disk /dev/dm-0: 4150 MB, 4150263808 bytes 255 heads, 63 sectors/track, 504 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xa668cfe8 Disk /dev/dm-0 doesn't contain a valid partition table Is it gone?

  • How to ensure nvidia_current module loads during boot

    - by Aras
    I am running Ubuntu 12.10 on an Asus G75V laptop with nvidia gforce GTX 660M. I first run 12.04 on this machine and was able to install nvidia_current drivers from swat ppa: sudo apt-add-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get install nvidia-current This worked in 12.04 and after rebooting the machine my graphics where working properly. After upgrade to 12.10 however, the machine boots into a low resolution desktop which I can not really interact with. I suspect this is due to the driver not being loaded properly. To fix this, I have to switch to ctrl+alt+F1 session and manually load the nvidia_current module and restart the desktop manager: sudo modprobe nvidia_current sudo service lightdm restart Now everything works fine again. However, I would like not to have to do this every time I reboot the machine. I also dont want to hack an script to do this on load. Basically, if things are setup currectly, the nvidia_current driver which is installed should load. How can I make sure nvidia_current driver module loads properly when system starts?

  • Is Visual Source Safe (The latest Version) really that bad? Why? What's the Best Alternative? Why? [closed]

    - by hanzolo
    Over the years I've constantly heard horror stories, had people say "Real Programmers Dont Use VSS", and so on. BUT, then in the workplace I've worked at two companies, one, a very well known public facing high traffic website, and another high end Financial Services "Web-Based" hosted solution catering to some very large, very well known companies, which is where I currently Reside and everything's working just fine (KNOCK KNOCK!!). I'm constantly interfacing with EXTREMELY Old technology with some of these financial institutions.. OLD LIKE YOU WOULDN'T BELIEVE.. which leads me to the conclusion that if it works "LEAVE IT", and that maybe there's some value in old technology? at least enough value to overrule a rewrite!? right?? Is there something fundamentally flawed with the underlying technology that VSS uses? I have a feeling that if i said "someone said VSS Sucks" they would beg to differ, most likely give me this look like i dont know -ish, and I'd never gain back their respect and my credibility (well, that'll be hard to blow.. lol), BUT, give me an argument that I can take to someone whose been coding for 30 years, that builds Platforms that leverage current technology (.NET 3.5 / SQL 2008 R2 ), write's their own ORM with scaffolding and is able to provide a quality platform that supports thousands of concurrent users on a multi-tenant hosted solution, and does not agree with any benefits from having Source Control Integrated, and yet uses the Infamous Visual Source Safe. I have extensive experience with TFS up to 2010, and honestly I think it's great when a team (beyond developers) can embrace it. I've worked side by side with someone whose a die hard SVN'r and from a purist standpoint, I see the beauty in it (I need a bit more, out of my SS, but it surely suffices). So, why are such smarties not running away from Visual Source Safe? surely if it was so bad, it would've have been realized by now, and I would not be sitting here with this simple old, Check In, Check Out, Version Resistant, Label Intensive system. But here I am... I would love to drop an argument that would be the end all argument, but if it's a matter of opinion and personal experience, there seems to be too much leeway for keeping VSS. UPDATE: I guess the best case is to have the VSS supporters check other people's experiences and draw from that until we (please no) experience the breaking factor ourselves. Until then, i wont be engaging in a discussion to migrate off of VSS.. UPDATE 11-2012: So i was able to convince everyone at my work place that since MS is sun downing Visual Source Safe it might be time to migrate over to TFS. I was able to convince them and have recently upgraded our team to Visual Studio 2012 and TFS 2012. The migration was fairly painless, had to run analyze.exe which found a bunch of errors (not sure they'll ever affect the project) and then manually run the VSSConverter.exe. Again, painless, except it took 16 hours to migrate 5 years worth of everything.. and now we're on TFS.. much more integrated.. much more cooler.. so all in all, VSS served it's purpose for years without hick-up. There were no horror stories and Visual Source Save as source control worked just fine. so to all the nay sayers (me included). there's nothing wrong with using VSS. i wouldnt start a new project with it, and i would definitely consider migrating to TFS. (it's really not super difficult and a new "wizard" type converter is due out any day now so migrating should be painless). But from my experience, it worked just fine and got the job done.

  • Difficulties with rotation of a sprite

    - by Andy
    I want to program a dolphin that jumps and rotates like a real dolphin. Jumping is not the problem, but I don't know how to make the rotation. My dolphin always rests in the same angle while it jumps. But I want that it changes the rotation during the jump, like a real dolphin does. How can I improve the rotation? public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D image, water; float Gravity = 5.0F; float Acceleration = 20.0F; Vector2 Position = new Vector2(1200,720); Vector2 Velocity; float rotation = 0; SpriteEffects flip; Vector2 Speed = new Vector2(0, 0); public Game1() { graphics = new GraphicsDeviceManager(this); Content.RootDirectory = "Content"; graphics.PreferredBackBufferWidth = 1280; graphics.PreferredBackBufferHeight = 720; } protected override void Initialize() { base.Initialize(); } protected override void LoadContent() { spriteBatch = new SpriteBatch(GraphicsDevice); image = Content.Load<Texture2D>("cartoondolphin"); water = Content.Load<Texture2D>("background"); flip = SpriteEffects.None; } protected override void Update(GameTime gameTime) { float VelocityX = 0f; float VelocityY = 0f; float time = (float)gameTime.ElapsedGameTime.TotalSeconds; KeyboardState kbState = Keyboard.GetState(); if(kbState.IsKeyDown(Keys.Left)) { rotation = 0; flip = SpriteEffects.None; VelocityX += -5f; } if(kbState.IsKeyDown(Keys.Right)) { rotation = 0; flip = SpriteEffects.FlipHorizontally; VelocityX += 5f; } // jump if the dolphin is under water if(Position.Y >= 670) { if (kbState.IsKeyDown(Keys.A)) { if (flip == SpriteEffects.None) { rotation = 45; VelocityY += 40f; } else { rotation = -45; VelocityY += 40f; } } } else { VelocityY += -10f; } float deltaY = 0; float deltaX = 0; deltaY = Gravity * (float)gameTime.ElapsedGameTime.TotalSeconds; deltaX += VelocityX * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; deltaY += -VelocityY * (float)gameTime.ElapsedGameTime.TotalSeconds * Acceleration; Speed = new Vector2(Speed.X + deltaX, Speed.Y + deltaY); Position += Speed * (float)gameTime.ElapsedGameTime.TotalSeconds; Velocity.X = 0; if (Position.Y + image.Height/2 > graphics.PreferredBackBufferHeight) Position.Y = graphics.PreferredBackBufferHeight - image.Height/2; base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); spriteBatch.Begin(); spriteBatch.Draw(water, new Rectangle(0, graphics.PreferredBackBufferHeight -100, graphics.PreferredBackBufferWidth, 100), Color.White); spriteBatch.Draw(image, Position, null, Color.White, MathHelper.ToRadians(rotation), new Vector2(image.Width / 2, image.Height / 2), 1, flip, 1); spriteBatch.End(); base.Draw(gameTime); } }

  • Two components offering the same functionality, required by different dependencies

    - by kander
    I'm building an application in PHP, using Zend Framework 1 and Doctrine2 as the ORM layer. All is going well. Now, I happened to notice that both ZF1 and Doctrine2 come with, and rely on, their own caching implementation. I've evaluated both, and while each has its own pro's and cons, neither of them stand out as superior to the other for my simple needs. Both libraries also seem to be written against their respective interfaces, not their implementations. Reasons why I feel this is an issue is that during the bootstrapping of my application, I have to configure two caching drivers - each with its own syntax. A mismatch is easily created this way, and it feels inefficient to set up two connections to the caching backend because of this. I'm trying to determine what the best way forward is, and would welcome any insights you may be able to offer. What I've thought up so far are four options: Do nothing, accept that two classes offering caching functionality are present. Create a Facade class to stick Zend's interface onto Doctrine's caching implementation. Option 2, the other way around - create a Facade to map Doctrine's interface on a Zend Framework backend. Use multiple-interface-inheritance to create one interface to rule them all, and pray that there aren't any overlaps (ie: if both have a "save" method, they'll need to accept params in the same order due to PHP's lack of proper polymorphism). What option is best, or is there a "None of the above" variant that I'm not aware of?

  • Headphones not working in ubuntu 12.04LTS

    - by mursalat
    So after a million warnings about not supported ubuntu OS, last night I finally upgraded to 12.04 - went somewhat smoothly (sadly) After my installation I got all excited with the exciting new look when I login, and all the new shebang, gently I installed chrome and went to youtube to check out some of my music and test flash in the process, now the sound worked awesomely, however when I plugged in my headphones, I could hear only a buzz-like sound when the base drops or there is a loud noise, maybe I didn't hear it from the headphones, but some other source. However sadly my headphones are not working, and I am a noob at fixing these stuff on Ubuntu. I've done loads of programming but when it comes to linux drivers and settings I seem to get frustrated. So I would really appreciate any help people! IN SUMMARY: My headphones are not working, my laptop's internal speakers are working awesome. To be as helpful as I can I have pasted the output from lspci -v to http://pastebin.com/VQNzDkZs I have also checked the volume levels from alsamixer and none are on mute. If you need any more information, please just ask, and I will be checking this post every 3 to 4 hours! Cheers!

  • Duplicated menu, panel indicators and taskbar

    - by Mykro
    Ubuntu 12.04. The first time I log into Gnome Classic I get a duplicate of every menu, panel indicator and taskbar entry. If I log out and back in again I now have three copies. Log out and log in, four copies and so forth. What would cause this? I can't see any obvious duplicates in the process list: $ ps -A | grep 'gno\|org\|nau' 27439 tty7 00:00:18 Xorg 27610 ? 00:00:00 gnome-keyring-d 27621 ? 00:00:00 gnome-session 27674 ? 00:00:00 gnome-settings- 27709 ? 00:00:07 gnome-panel 27720 ? 00:00:00 gnome-fallback- 27726 ? 00:00:04 nautilus 27736 ? 00:00:00 polkit-gnome-au 28281 ? 00:00:00 gnome-screensav 29016 ? 00:00:00 gnome-terminal 29021 ? 00:00:00 gnome-pty-helpe If it helps, I was recently trying the Nouveau drivers but have now reverted to NVIDIA. Configuration is Separate X Window, Xinerama enabled. Unity is fine, so the problem is limited to the Classic desktop. I haven't had any luck googling these particular symptoms so any tips would be really appreciated. Thanks!

  • Kubuntu not showing eth0

    I just installed Kubuntu 12.04.2 and do not have an internet connection. I also cannot access the Desktop and only have the terminal. When I enter xlcock I get Error: Can't open display:. I believe this is because I do not have the correct drivers and need to download them ... using the internet which I can't access.
