• Password Authentication Problems

  - by Bobby Hathorn

  I am new to Ubuntu, am extremely delighted with the performance and speed, as compared to Windows 7-However, I messed up, I think...when I booted my USB disc, I set a password, as directed, and when Ubuntu booted up I tried to reset my password via User Accounts to "None". Now, the Password Authentication window prevents me from downloading software, (Audacity and my Ubuntu updates. Also, I've tried to boot into GRUB and the Recovery Console, as directed; however, the PC bypasses GRUB and boots into Ubuntu instead. Also, when attempting to use the terminal as directed to change the password, I'm given a password prompt there also. If the problem is on my end, could you email/reset my password? My PC is an emachines EL1358G. I am otherwise happy with Ubuntu!

• Compiz using 40% CPU on Ubuntu 13.10

  - by Olli

  After upgrading to 13.10, compiz process has started taking up to 40% of CPU resources. In addition, Unity is sluggish just like in this recent question Compiz at 30% of CPU on Thinkpad T420. My PC is HP Compaq NX6310 and Compiz version is 0.9.10.2. First I had error message during boot, but did find solution for that (Bug #1014289) by updating the kernel to newer 3.11.4, it did not change the CPU usage. For the CPU problem I tried solution for Bug #1221837 by adding the line MESA_GL_VERSION_OVERRIDE=1.4 in the file /etc/environment - that did not help me, so my problem seems not to be the same bug. Any suggestions on how to resolve this issue?

  I'm running Ubuntu 10.10 with ATI proprietary FGLRX graphic drivers When I boot, I can see this very quick message appearing; I don't have time to read it: **Fatal Error ..................................**(&@something i cant read) I searched through the log file in /var/log/ in order to find what is wrong and I did find something in the /var/log/Xorg.1.log: 21:31:08 [ 15.734] (--) using VT number 1 [ 204.647] Fatal server error: [ 204.647] xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call [ 204.647] [ 204.647] Please consult the The X.Org Foundation support at http://wiki.x.org for help.

• Which iso image do I need to install Ubuntu 12.04 on a Macbook Pro so that it boots using UEFI?

  - by gentmatt

  Unlike with earlier releases, the website is unclear on giving a straight recommendation for installing ubuntu on a mac: http://cdimage.ubuntu.com/releases/12.04/release/ I've read several times, that I should use an alternative image. But this is only offered as 64-bit. However, I'm also told to rather use 32-bit images for better software compability. http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-alternate-amd64+mac.iso Even though I should only use alternative images, there is offered a standard desktop image which is "adjusted to work properly on Mac systems". http://cdimage.ubuntu.com/releases/12.04/release/ubuntu-12.04-desktop-amd64+mac.iso Question Which image should I take? Do both of these images offer UEFI boot? I've tried both of them already, but both have setup an install with BIOS emulation. This is quite annoying because of the short battery life and high temperatures which are harmful to battery longevity.

• DIY Wirelessly Charged LED Lanterns

  - by Jason Fitzpatrick

  Earlier this year we shared a clever project that turned LEDs, batteries, and PVC into mini, waterproof, and virtually indestructible lanterns. This remake of the project makes the units rechargeable. Our favorite part about this project–the upgrade to an older project and the introduction of wireless charging aside–is the fact that the maker behind it is 15 years old. It’s great to see younger people taking an interest in tinkering!

• How to recover partially removed components of ubuntu-desktop?

  - by Rick_2047

  So I was messing around with tasksel to install LAMP. Foolishly I unchecked the ubuntu-desktop item. About 25% through the process I realized it is removing my desktop components. So I closed the terminal window, but now maybe something went wrong. Many default applications are gone and I can't even boot into the desktop. I have a separate home folder so I don't really have to worry about data, but I did install a lot of other software which would be gone if I take reformat and reinstall. So is there a way to recover the desktop from a live CD?

• Kernel Panic while Installing Ubuntu 12.10 from USB Drive

  - by user100889

  Good evening, I recently looked into installing Ubuntu alongside my Windows. I was able to mount the iso on a USB drive using Universal USB Installer. I verified it with the MD5sum utility and the hash is correct. When installing, I can get to the screen where I choose the boot order, select the USB drive, and then I get to a screen where Ubuntu seems to be 'loading' (purple background with Ubuntu logo and name in the middle). Then, all of a sudden, I get a "Kernel Panic - Not syncing: fatal exception in interrupt" error message. My specs : Intel Core 2 Duo CPU T5850 @ 2.16 GHz / 4 GB of ram / Packard Bell computer from 2007. / Windows 7 Ultimate x64 installed. What should I do now ? Thanks for your help.

• can't control pianobar after using echo

  - by Ubuntuusr22222

  I have a script that starts pianobar (pandora player) and autoloads into tty2 after booting. I'm running Ubuntu Precise 12.04. it's a pretty simple script: #!bin/bash sleep 5 echo "2" | pianobar This works, it selects station 2 and begins playing... but when I try to type in commands it doesn't work (like pushing "p" for pause.) It'll show the letter for a second, then hide it. If I try to exit with ctrl+z it just sits there and I can't use it at all. If I run this it works fine but doesn't auto-select the second station: #!bin/bash sleep 5 pianobar Is there anyway to write this so it will automatically input "2" and then allow me to control from there? Or am I stuck with having to select 2 every time I boot up?

• Kubuntu permanent install won't attach sound card

  - by rob

  I installed Kubuntu Live version and sound card visible in the volume/mixer panel. After installing the permanent version I have a dummy output where my sound card should be, therefore no sound. I re-installed the live version three times and then to permanent but the same problem each time. There is a very brief error on boot up to the permanent version that says: error. cannot attach card default. no such file or directory. I'm running Kubuntu 12.04 on a Mac G4 PPC with no other OS. I'm very new to Linux. I am able to follow instructions to help resolve this, but I'm not familiar with the OS.

• Changed profiles; lost Ubuntu; how do I get it back?

  - by Tim

  Installed Ubuntu-secure-remix 12.10 in a dual boot with Windows 8 on an HP laptop. A first-time Linux user, I was exploring settings when I changed profiles (not sure what I changed it to). Now the Linux boots into what I believe is the shell. I can still log in (that is, I am already a user - so that's still there). Due possibly to using rEFInd, I cannot figure how to run Ubuntu in recovery mode. How can I get Ubuntu back up and running again? Thanks in advance.

• Will 3D games run in a VirtualBox4-hosted Windows system under Ubuntu with Intel GMA X4500HD card?

  - by Ivan

  I've just got a laptop with Intel GMA X4500HD card (which is said to be DirectX10-compliant, while my previous laptop had Intel 82852/855GM and no chance to play modern 3D games at all). It would be nice if I could play some games (like HalfLife 2, StarCraft 2, Fallout 3) from time to time (while I am ok using lo-fi settings and having low performance) but as I strongly prefer Ubuntu environment and don't need Windows usually I'd like to install Windows inside VirtualBox instead of using a dedicated partition and dual-boot. So the question is if VirtualBox can use 3D acceleration of Intel GMA X4500HD if run on Ubuntu.

• FatCow and iPage real deal?

  - by Tribbey

  I need a cheap host that I can upgrade if needed for a startup. From searching, FatCow and iPage seem reliable and inexpensive web hosting services with a Unix OS and good bandwidth + disk space. I suspect they were bought from the same company. They propose to offer unlimited bandwidth/disc space and perks like AdSense/Facebook credit however, they're packages range from 1-3 years @ 3.15 USD/mo, there isn't a monthly package but they do allow you to cancel at anytime and there servers run on wind-mill generated energy which is a plus. I was suspicious because I couldnt seem to find one negative review about them, just affiliate pages until I read a review explaining they're strict policies on copywritten data. Has anyone experience with one of these two hosts?

• HP Bluetooth Mouse Connection Problems

  - by Arthur Upfield

  About a month ago, I turned on my laptop (Ubuntu 14.04 and Windows 8.1 dual boot, though the mouse works fine in Windows), logged in and connected my HP x4000b mouse via a bluetooth dongle (Kinivo BTD-400), and noticed that the battery indicator in Ubuntu said that the mouse battery was at 0%. The day before it was around 30%, so I decided to just change the batteries in the mouse, but after reconnecting with the new batteries, it still said 0%. The mouse connected and worked just fine, so I didn't think much of it. About a week after that, I noticed that my mouse would sometimes disconnect if I didn't use it, but since reconnecting isn't that hard I just decided to leave it. Now it also won't reconnect unless I log out and back in again, which is getting sort of tedious. Is there any way to fix this issue? Any help is appreciated, and I will try and respond to questions ASAP. Thanks.

• Time display and Cursor bug in Ubuntu 14.04 LTS

  - by user291774

  Just installed Ubuntu 14.04. Noticed the time in seconds speeds up then slows down to normal speed. The cursor for the keyboard has a strange rhythm; it stays normal, then slowly speeds up faster and faster till it looks like it's not blinking anymore, then goes back to normal and starts the process again. It almost seems like my whole operating system speeds up then slows down again. Even the hour circle that spins when it's loading starts slowly then it picks up speed till it spins so fast it looks like it's not even spinning. It interferes with video and the whole system. I have a Dell Vostro 3750 dual video cards and dual boot with Windows 7. Windows is running fine.

• How to use encypted home directory after reinstallation

  - by user15533

  I reinstalled Ubuntu on a machine with encrypted home directories. After that installation I have edited the fstab to boot the old home partition in /home. After doing so I can not login anymore with LDM. If I type my password, witch is the same as before, after a short moment of activity I am referred back to login page. I think this is due to the fact, that my home directory is not decrypted correctly. But I read here that this should work. What am I supposed to do?

• Ubuntu 11.10 USB 3.0 HDD

  - by Chazm

  I have a problem with my external HDD (WD My Book Essential 1TB) working on USB 3.0 port. I'm using dual boot setup with Windows 7 and Ubuntu 11.10, both 64 bit. While I'm running Windows and rebooting back to Windows everything works well. When I'm switchin to ubuntu everything works great as well. But after 1st reboot from ubuntu neither windows nor ubuntu mount the external drive. I have to reboot the device manually. I suspect that the problem is with unmounting the device on shutdown on ubuntu. The case concern only usb 3.0. When i plug the same device into usb 2 port the problem doesn't persist. Does any1 hit the same problem or have a clue what might goin wrong?

• Will everything (downloaded fonts, files, apps etc) remains the same when I upgrade from Maverick to Natty?

  - by Suffi

  I'm planning to upgrade from Maverick to Natty, and to try out Unity, but I don't want to lose any settings, customizations and downloads in Maverick. I just want to know, if upgrading alter anything that I said earlier? I don't want to start over with a clean, fresh Natty, and I hope I can keep all of my files and folders and settings in Maverick, and to have them in Natty after the upgrade. Is this possible? Should I use Update Manager to achieve this? And would all my compiz-settings be reset after I upgrade? Sorry for too much questions, but I'm asking this because you know, in Windows, any version upgrade would require the disk to be reformatted. I hope Ubuntu is more convenient than that.

• 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.

• Cannot get grub menu to timeout (or go away)

  - by Eric

  I am running Ubuntu 12.04. I cannot for the life of me get the grub menu (with options) to go away. I would like it to auto-boot into the first option. I've edited /etc/default/grub so that it looks like the following: GRUB_DEFAULT=0 GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=10 GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian` GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" GRUB_CMDLINE_LINUX="" After this, I ran sudo update-grub. Then I realized that I had grub 2, so I ran sudo update-grub2 (both make it look like they create the grub.cfg file successfully. I restart my computer and it goes back to the grub menu and just sits there until I make a choice. This is not desirable if the power goes out... :-) I also tried reinstalling grub using sudo grub-install /dev/sda - also unsuccessful
