• No sound coming from HDMI

  - by cypwrx

  (Ubuntu 12.04 x64) After looking at other questions (here and other sites) and trying their respective answers, I am still unable to get the hdmi audio out working. I have downloaded the recommended hardware drivers for my card (radeon hd 4350), made sure that the card is not muted in alsamixer, and set it as the correct output device in sound settings. I have also disabled the onboard sound devices in the bios menu. In aplay -l, it shows my hdmi card as hw:0,3 Even after doing sound tests I still cannot hear anything. Any suggestions? Not sure where to go from here, I am fairly new to linux.

• Win7 installation on VirtualBox

  - by Will

  I have Ubuntu 12.04 installed on my machine. I also installed Virtualbox so that I can run windows 7. I set my virtual box with 4 GB RAM and 25 GB virtual HDD and after I press Start, it doesnt boot from the windows dvd in the optical drive, but instead i get this error: Failed to open a session for the virtual machine win7. VT-x features locked or unavailable in MSR. (VERR_VMX_MSR_LOCKED_OR_DISABLED). Result Code: NS_ERROR_FAILURE (0x80004005) Component: Console Interface: IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb} Do you have any idea what is it and how I could overcome this? Thank you!

• CPU spikes cause audio stuttering in Audacious when browsing? (Lubuntu)

  - by Alucai Vivorvel

  My default audio player is Audacious, browser Google Chrome. I tried Firefox, and while I love it, the CPU load spikes when doing something as simple and small and switching a tab, which causes the audio playing to stutter (as sound is onboard and handled thru the CPU). Chrome doesn't do this as much, but there is the occasional stuttering when browsing, which is ridiculous, as not even Windows Vista does this. So I thought maybe it's something to do with how Lubuntu handles sound, I checked and only ALSA was installed. I tried installing PulseAudio, but, while the music "plays", nothing comes through the speakers. Immediately after switching back to ALSA the music pours out of them. So I was wondering if you had any idea what was going on here. I asked on Ubuntu Forums but apparently my problem is too complex, as it's been over a week since the last reply. Specs are: AMD Athlon 64 3200+ @ 2GHz 2GB Corsair 667MHz DDR2 RAM ATi HD Radeon 3650 (AGP) 512MB 500W Cooler Master PSU 80GB SATA II HDD (Vista is installed on 500GB drive) Biostar K8M800 Motherboard

• Accidentally deleted my windows 7 while installing ubuntu, trying to reinstall it

  - by user286874

  I had Windows 7 Ultimate on my desktop and I believe have downloaded the correct ISO file. I've been trying to use GParted and UNetbootin to create a bootable usb by formatting to FAT32, flagging the boot box, and writing to the flash drive with UNetbootin, but there have been problems. When I select my flash drive in the BIOS, it just reflashes the BIOS stock MSI picture 4 times then boots to Ubuntu anyway. Details: it's a new computer, self-built, hasn't shown any problems in the past, got Windows 7 through r/softwareswap so it's a MSDN file, the flash drive is a Sandisk U3 Cruzer, I uninstalled the bloatware when Iwas using Windows 7, but in the BIOS it still comes up as "Sandisk U3 Cruzer" I don't have a cCD/DVD drive. I dont care if I have to completely delete ubuntu in the process, I just need Windows 7 back by monday. I think the problem is because of the cruzer and am going to pick up a different flash drive today.

  - by FilthyCasual

Trying to get the latest AMD Radeon drivers automatically installed? the main file downloads...but just shows up in a window full of files but idk where to drag them. And PlayOnLinux my one hope for gaming since Steam is buggin out without proper drivers? Can't figure out where to "mount" the DVD version it asks for. I'm so lost. I dove head first into the Linux thing thinking it was wildly superior, and maybe it is, but dang if the simplest things aren't hard to do. Any help appreciated. I've been reading guides and manuals but what I need is human experience most of all.

• Getting Started with 12.04 LTS Problems

  - by mark

  Okay previously I used ubuntu 10.04 in Desktops and Loved it! I bought a newer Toshiba Satellite with an i7 CPU, 8GB Ram, 1TB HD, first thing I tried to do was install Ubuntu 9 on it then I found out it was no longer Supported. (I gave my 10.04 disk away) So I tried installing Windows 7 and experienced SO MANY problems, I am going back to try 12.04. Starting all over again. After installing 12.04 Wireless was Detected yet said it was Disabled by a Hardware Switch. Went read through the Message Boards found Solution which was Sudo rf Kill All. Okay all excited I would finally get my Ubuntu to finally work I rushed back to my laptop from the internet cafe, and went looking for the TERMINAL input on my Ubuntu 12.04, and I cannot find the Terminal. If I can't find the TERMINAL how Can I enter any Sudo Stuff? So I guess the first question is Where is the Terminal Located in 12.04? Thank you.

• Can't boot ubuntu 12.04, stuck in busybox. Can't view files from ubuntu trial disc, or windows partition

  - by Maura

  So, I'm slightly computer literate, and find myself frustrated and overwhelmed. My computer is a acer laptop, extensa 5620-6572. I have a dual boot with windows vista and ubuntu 12.04. The ubuntu 12.04 I got was from an upgrade, not a disc. I tried to load ubuntu 12.04, and it gets stuck in the "busybox", and I don't know how to proceed from there. I went to my windows partition and downloaded Ex2 from http://sourceforge.net/projects/ext2fsd/ and thought I'd try access my files and save them to a external HD. Then when I restarted my computer and went to windows, it always freezes after it loads the OS. So then, I downloaded and burned a ubuntu 12.04 boot disk, and the disk works fine. But I still can't figure out how to view files on my harddrive.

• No video signal after install

  - by tW4r

  Today I tried to install Ubuntu 12.10 to my machine, but all the time I encountered the same problem, I successfully boot from Ubuntu 12.04 DVD, and a purple background comes up with accessibility and keyboard icons at the bottom of the screen, then when you wait a while a monitor text comes up "No signal" (Keep in mind that this signal is only shown when there's cable in the monitor HDMI plug), and nothing happens, a little later disk drive stops flashing meaning that disk finished being read. Even if you reset the computer you still get no signal, you have to turn the power of and on again, and plug HDMI out and put it in again. My info: Graphics card: ATI/AMD Radeon HD 4850 Connection to monitor: HDMI Monitor: Samsung SyncMaster T220HD

Can you give me some solution for this?

• DRIconf in Ubuntu 64x plus ATI GPU or something more?

  - by Balask

  I've been trying to get Call of Duty 2 to work in Wine in Ubuntu. It gives me a black screen. So I tried the fix suggested by the wine apphq and downloaded DRIconf. Funny thing is that it can't find my direct rendering device. "Could not detect any configurable direct-rendering capable devices. DRIconf will be started in expert mode" When I enter into it in Expert Mode is just errors out anyway. fglrxinfo gives me: display: :0 screen: 0 OpenGL vendor string: Advanced Micro Devices, Inc. OpenGL renderer string: ATI Mobility Radeon HD 4200 Series OpenGL version string: 3.3.11627 Compatibility Profile Context That shows me my driver is installed correctl,y right? World of Goo which is Linux native and requires direct rendering works like a charm. So I'm wondering, is there some other workaround? Is there a bigger issue? Does me running 64-bit affect it at all?

• Boot prompt hyphens

  - by purjuntu

  Booting an Ubuntu DVD, pressing F6 and then ESC presents the boot prompt with the default kernel options, with the possibility of editing and adding extra options. Something like: kernel /casper/vmlinuz boot=casper quiet splash -- Questions: What's the meaning of the two hyphens? When adding an extra option (such as "toram" or "vga=791"), is there any difference between adding it BEFORE or AFTER the hyphens? When typing commands in Bash, two hyphens in a row means "options end here; anything that follows should be treated as an argument, even if it starts with a hyphen". But the hyphens must have another meaning at the boot prompt, as "toram" or "vga=791" really are options.

• Not sure which Ubuntu to install (64 or 32 bit)

  - by user285993

  I want to use Ubuntu. I have Win 7 Home Premium 32-bit right now... I used to have 64 on this laptop (Toshiba Satellite c650) but my disc got a ring of death. Intel Penium CPU B940 2.00GHz, 4GB RAM Also, I'm guessing I need an image mounter such as PowerISO to install Ubuntu, if I don't have a DVD lying around that I can mount to? I'm a noob. Thanks for your help, in advance. EDIT: My question wasn't clear... can my processor and RAM handle 64-bit Ubuntu? Hell of a lot nicer than Win7

• Ubuntu 14.04 upgrade succeeded partially - I would like to use a different mirror; how can I do that?

  - by user290648

  When I wanted to upgrade from Ubuntu 13.10 to 14.04 the update manager told me that there was an unresolvable problem with calculating the upgrade. In order to see more details I performed the following on the command line: apt-get update apt-get upgrade apt-get dist-upgrade apt-get install update-manager-core do-release-upgrade Now do-release-upgrade tells me that no newer version is available but the "about" box in the main menu tells me I am still on 13.10. I think the latter is right, as for instance in the "system settings" there is no way to select local menus, which is present in 14.04 (I tried with a DVD, and there it is). Maybe the problem is related to the fact that "apt-get update" cannot get two resources called "saucy/InRelease" and "saucy/main/binary-i386/Packages" from the mirror (mirror.informatik.uni-mannheim.de; 404 not found). I would like to use a different mirror; how can I do that? Any help appreciated, thanks in advance.

• Why does Ubuntu Freezes on ASUS K42DY laptop with RADEON HD6470M Graphics Card?

  - by ix3

  Hi,I have an ASUS K42DY laptop with AMD Phenom II x2, 8 GB Ram , 500 GB Hard Drive and has a didicated ATI RADEON HD 6470M Graphics Card and I'm running Ubuntu 12.04 LTS 64bit on it. I have installed GNOME 3 and also followed this Make Ubuntu look like Mac OS X. I have also installed apps from the software center, getdeb & playdeb all of which worked fine. However, I noticed that Ubuntu freezes after inactivity let's say 1-3hrs. I have already set power setting to never standby or hibernate. This is completely annoying because all I can do is log-out via ctrl+alt+del or manually shut down and reboot my laptop. What should I do? By the way, this happens on all shells Unity, Gnome (even with the basic) and Cairo Dock.I set Swap Space at 8GB during installation. Any help will be appreciated. Thanks!

• Why is FTP file transfer from Android Phone Slow?

  - by Frychiko

  To transfer files from my Android phone to Ubuntu, I use an app that creates a FTP server on the phone. Copying files to Ubuntu 12.04 (same with 12.10) I get up to 260 KB/s. Copying files to Windows 7 I get up to 1050 KB/s. I am currently on a fresh install of 12.10 with barely anything installed with the same results. I have tested with both a Galaxy S3 and HTC Desire HD with identical results. I have tested about 5 apps with the same results. Why is it slow on Ubuntu?

• poor font rendering in browsers on 12.04

  - by Alecs

  I'm using a Lenovo B570e. I've installed the mesa-utils for the graphic driver because it wasn't recognized by default. Now I have this: graphic card : Intel® Sandybridge Mobile x86/MMX/SSE2. I don't know if it's just my impression but I think all the images are a little bit pixelated and I think it have something to do with the drivers. Maybe is not the correct driver associated with it, I'm saying this because when I was on Windows 7 the name of the driver was something like " Intel hd graphics..." Any suggestions? Thank you! Later edit: This seems to happen only in browsers.

• Delete all traces of windows from Ubuntu

  - by TheOm3ga

  I used to have a dual boot in one of my hard disk drives - Ubuntu and Windows 7. Then, I added a SSD which is now my main hard disk drive, and I'm using it for Windows 7 completely, keeping Ubuntu in the old HD. I restored the Grub so everything works ok, except for one thing. Everytime I update the grub, it detects two windows: Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 Obviously, I don't want it to detect the Windows on sdb1. Because I no longer use it (I manually deleted the files). What can I do about that without wiping out completely the partition?
