• Corsair Hydro i series cpu cooler fan control

  - by user214690

  Im relatively new at Ubuntu and have found an answer to basically every single issue ive ever had thru this site... Otherthan this. I have been toying with the idea of a Corsair h80i for my dual boot system (win7/U12.10) and mostly use it in ubuntu. I have done some research on the interweb regarding fan control in linux and nearly ran up short untill I came across this thread: http://ubuntuforums.org/archive/index.php/t-2096166.html And it seems to have worked around it. (altho I have not tested it for myself) Is there any program/library/source that can be used to control the fans without having to MacGuyver it??

• How to upgrade from 11.10 to 12.04?

  - by Marco

  I am using 11.10 and I really want to update to 12.04 but it's impossible. I cannot see it in the update manager (I did select the option for the releases). I tried sudo update-manager d, and sudo-apt get upgrade and sudo apt-get upgrade release d but nothing. And sudo do-release-upgrade is not working as well! (I get "no release found" message.) So finally I did put on a live USB and when I boot, I click on install, then it's telling me that I do have 11.10 and I can select for erase all and install Ubuntu 12.04 or I can install along 11.10 and the second option to update 11.10 to 12.04 is grey. I cannot selected it! Why? Am I running out of options? What else can I do to upgrade to 12.04?

• How to make Ubuntu LiveCD be able to use USB Flash drive and external hard drive?

  - by ????

  I am booting up Ubuntu 2012.04 LiveCD... and was able to do /sudo mount /dev/sda1 /mnt and be able to see files in /mnt, which is the main hard drive that can't boot up any more. So to copy files from /mnt to an external hard drive or USB flash drive, I connected a 1TB external hard drive and 2 USB flash drives to the computer, but for some reason, in "File Systems", I can't drag and drop files from /mnt into those external hard drive or USB flash drives? I can't open or look into those drives either... How to make it work?

• Wireless Very slow with 13.10 and BCM4313

  - by RyanCheu

  I have a laptop with the BCM4313, and it was working perfectly in Ubuntu 13.04, but I recently upgraded to 13.10 and now my wireless performance is horrible. Initially it didn't work at all, but I removed the wl driver and use the brcmsmac driver instead. Now when I boot up it works at the start, but gets progressively slower. My Android device is reporting 10Mbps down/20Mbps up, but my laptop only gets 1up/down. Does anyone know a solution? I really need my wireless to work, is my best option to just reinstall on 13.04? Thanks!

• upgrade from ubuntu 12.04 to 12.10 failed, now loads "grub rescue"

  - by Greg

  I attempted to upgrade from 12.04 to 12.10 last night. Installation seemed to go fine, and this morning I had a message like "restart now to complete installation". So I restart, get an initial "Loading Operating System ..." message, followed by "error: file not found. Then it kicks into "grub rescue" mode. Previously I have this running as a dual boot (window 7) and I just ran the upgrade to 12.10 via the update manager in ubuntu. Any ideas on what is going on here, or what the error means? I know my way around the command line, but this is above my pay grade. Thanks for any advice.

• installing win7 x64 in VirtualBox - error driver device missing

  - by chrisjlee

  After creating a vhd and going through that process i'm unable to install win7 x64. I've went through various settings and trying to get it right. It'll boot the windows install but then indicate the following error (image included too): A required cd/dvd drive device driver is missing. If you have a driver floppy disk, CD, DVD, or USB flash drive, please insert it now. Note if the windows installation media is in the CD/DVD drive, you can safely remove it for this step. I've also set up my storage tree like so: Would anyone know what the issue could be? It's asking for cd/dvd device drivers and i'm unable to install.

• System crashes when internet connection is unplugged

  - by Rincewind

  When i first tried to install any ubuntu newer than 10.04 on my netbook (Acer aspire one 722 11,6" WXGA - C-60 Dual Core APU - AMD Radeon HD 6250 - 1x HDMI - 2GB DDR3 - 320GB - 802.11bgN - 6CELL2.2 - BT 3.0 - VGA Webcam), it would fail to boot. I found out that the only fix to this was linking it to the internet via lan-cable during the installation. However, after installing ubuntu 12.04 successfully my system is crashing everytime i unplug the lan-cable. My first thought was disabling the netbook´s w-lan (via the band at the top) but it was not fixing the problem. Looking on the taskmanager ('top') during the process brought no further insight, no process was exploding or something like that. As i am out of guesses help would be really appreaciated.

• DrRacket icon doesnt work?

  - by Laurie

  I installed DrRacket from the Ubuntu Software Center. All went well and an icon appeared however nothing happened when I clicked the icon so I removed it. Then went to the Developer website and downloaded full-5.3.0.21-bin-x86_64-linux-debian-squeeze.sh. I installed this via Terminal with sudo apt-get install racket. The DrRacket icon came back in Dash Home but again clicking it nothing appears to happen. How do I start DrRacket? I am running Ubuntu 12.04 LTS dual boot on a 64 bit Dell

• Incorrect key mappings in remote NX session

  - by Roger Light

  I'm using the NoMachine provided NX client on Ubuntu 10.10 running on a laptop. I'm connecting to a FreeNX server that happens to be running on openSUSE. I'm having trouble with keys being incorrect in the remote session. The most noticable example is that when I press up cursor, the screen shot dialog appears instead. As far as I can gather easily, the cursor keys and delete are affected. It's worth noting that it doesn't display the same behaviour if I dual boot to Windows XP, or from a different machine using openSUSE. I'm not really sure where to begin looking. Any suggestions?

• Failure to start grub with Wubi

  - by Marco Ceppi

  My laptop battery ran down and died while using Ubuntu 10.04 with Wubi. Upon recharge (and restart) selecting Ubuntu from the Windows Boot menu brings me to the typical prompt which says (and I paraphrase): Trying hd(0,0) on Disk... After that the screen flickers to white (for a split second) then black. No grub menu comes up (as I would expect) no cursor, no grub sh prompt. Nothing. I've tried switching TTYs to no avail. As there are no logs, I can't trouble shoot anything. I've run a check disk from windows (on the NTFS partition the root.disk is stored) with no luck. What is causing this failure to load grub (and, by association Ubuntu) - How can I restore my setup and get Ubuntu via Wubi working?

• Ghosting Program for Ubuntu 12.10

  - by Sean Webber

  I am looking to figure out how to set up a mass backup system for a computer network (of about 25) and am looking for a ghosting program that makes an image of the entire system for backup/recovery purposes. While clonezilla would work.. you have to manually boot us the CD for it. I am looking for a program that runs INSIDE Ubuntu that sends a system image backup off to the network server at set times, then when needed could also be used to burn the clone back to the machine. Another words- automatically and the only time I have to do anything to it is when I need to burn a backup BACK to a 'crapped' machine. Any ideas?

• Fail to load Ubuntu11.10 onto ASUS PC 1015PX

  - by strugglingbadly

  My new ASUS 1015PX has the usual windows on the SDA1 partition - 100Gb, followed by SDA2 - 15Gb - with the recovery for windows, SDA3 with 183Gb for drive 'D' for windows. ASUS uses SDA4 - 19Mb for it's own use. 11.10 on an USB will load Ubuntu on a try basis and it seems OK, but every time I attempt an install, Ubuntu quickly shuts down and the restart process begins. Repeat endlessly. I've tried 10.4 netbook but that will not boot at all with the machine reporting - unknown keyword in config file gfxboot vesamenu.c32: not a COM32R image. I've gone through the above about 6 times each with the same results. I have also tried the above with the partitioning unchanged, and using gparted, with SDA3 formatted to ext4, windows 'D' reduced to 8Gb providing a 175Gb unallocated space - all to no avail. Please help

• Ubuntu Variant / Linux Distros which uses least system resources (RAM, CPU)?

  - by elegantonyx

  I have a netbook (an older Asus EEEPC 1005HA) which I want to get rid of Windoze on (I like Windows, but I don't think it works well in a netbook environment). Basically, my question is which Ubuntu variant will use the least RAM and CPU running idle, and/or the same question except when running Firefox and Libreoffice Writer, say. I am also open to suggestions of non-Ubuntu Linux distros, but since this is AskUbuntu I thought the first question would be more appropriate. I have a disk drive which I can attach to the netbook, so it doesn't have to be a Ubuntu Variant / Linux Distro which solely boots from a USB drive. I have at my disposal: DVDs, DVD writer/ disk drive, 4gb flash drive, 8 gb flash drive I was thinking either Lubuntu or Archbang / Crunchbang but I would like some help from more knowledgable people Specs: Can't boot into it right now, but I think I have either Intel Atom N270 @1.60ghz OR Intel Atom N280 @1.66ghz (single core, I think) 2gb RAM 160 GB hard drive

• Brightness fn key adjustment problems

  - by npCoder

  My brightness function key controls work after setting grub boot parameter to "acpi_osi=" but using them I cannot adjust the brightness higher than around 70% (there is empty bar left over and I can't adjust higher) unless I go to Brightness & Lock settings manually than I can use the slider to adjust it higher... I primarily use intel_backlight to adjust my backlight and I am running Linux kernel 3.14.1 on Ubuntu 14.04 LTS on an ASUS X550LA Laptop when I try: cd /sys/class/backlight/intel_backlight cat max_brightness 937 cat brightness 811 It seems that I can only adjust to a maximum of 811 using the fn brightness controls If I instead do cd /sys/class/backlight/acpi_video0 cat max_brightness 10 cat brightness 4 cat actual_brightness 10 With the FN keys actual_brightness is not equal to the value returned from brightness on acip_video0 (which is always 4) but on intel_backlight actual_brightness = brightness The adjustment problem seemingly arises because both intel_backlight and acpi_video0 are trying to adjust brightness

• A LEGO-Themed Take On the Movie Inception [Video]

  - by Jason Fitzpatrick

  This Inception-inspired short film combines LEGO and CGI to great effect. Courtesy of a Staffordshire University design team, the short is a result of roughly a thousand hours of design work spread between seven students to serve as their semester project in visual FX. It has everything you could want from Inception rendered in LEGO: folding landscapes, flying bricks, an a LEGO man or two even loses his head.

• Ubuntu 13.10 upgrade error. Dropping to low graphics mode

  - by aero31aero

  I was updating from the terminal and it was complete. It asked me if I would like to reboot now. I accidentally pressed 't' instead of 'y' and then it just asked me to reboot manually. Then I rebooted using sudo shutdown now -r And on reboot, the system flashed the "low graphics mode" error screen and its stuck there. I have 13.10 live-USB with me. Is there any way I can get my system to boot normally? I'm not willing to do a fresh install as I had installed several other packages. Another question: is there any diff if I drop into terminal using Alt+Ctrl+F1 or if I use chroot from a live session?

• How do I install Ubuntu to a USB key?

  - by badp

  If you are hurrying to reply, System ? Administration ? StartUp Disk Creator -- no, that's not what I'm talking about. I want to try Ubuntu 11.04's Unity without touching my existing Ubuntu install. To do this, I need to install the nVidia drivers first (sigh). To do this, I need changes to persist a reboot. To do this, I need to really install Ubuntu on a USB key. How do you do that? What I tried I tried to make a USB key from Testdrive, then boot from it, then choose "Install Ubuntu." The installer refused to install to the installation media itself. I tried, from my installed copy of Ubuntu: sudo kvm /dev/sdb --cdrom .cache/testdrive/iso/ubuntu_natty-desktop-i386.iso ...but the installer didn't detect the disk properly.

I click on the HDD and obtain the following I honestly don't really know whats going on. Looking at disks I have this... Can anyone help me out? Cheers.

• Mouse cursor lag after lock screen, 64 bit 12.04

  - by Bill Jones

  Recently I have noticed that when I return to my computer after it has been "locked" for a while, the mouse pointer has significant lag. The cursor position appears to only update a few times a second. Moving the mouse results in the pointer "following" the movement in a jerky kind of way, and then continuing for some fraction of a second after I have stopped using the mouse. Replacing the mouse has no effect. (I have two differently branded and constructed usb optical mice). Plugging either mouse into a different usb port has no effect. Once the problem was resolved by "suspending" the system, and then re-starting it with the power switch, but this does not work every time. So far, the only fool-proof fix is to shut the system down and re-start it (re-boot). I have tried this suggested fix. It had no effect.

• Switching my legacy desktop back to Windows XP from Windows 7

  - by Kevin Shyr

  I was happy with Windows 7 at the beginning, until I started to add in the peripherals.  Windows 7 was never able to recognize any of my PCI video card (I know, I know, we should be in the DVI age). Anyway, I went through another 4 days of trouble setting my computer up with dual monitor in XP (also did a bunch of other things like getting rid of my sound card and taking the computer off RAID. Kind of feel stupid to put the computer on RAID in the first place because now I can have 2 drives: double the page files program seems to run faster Microsoft Sync toy 2.1 takes care of my backup needs (Thank god they solved the network drive issue) As of last night, the system is running beautifully.  I still have a laptop with Windows 7, but even that is in dual boot mode.

• Ubuntu 12.04 wont install on Macbook

  - by user92325

  I've installed Ubuntu on my Macbook before but something went wrong with the updater. So, I had to backup my HDD and format it and reinstall OS X Lion. But here's the thing: Ever since I re-installed my OS I've been trying to get Ubuntu back on the HDD. I partitioned it to 40 GB and set the file system to Ext4. I also recently created a swap partition too and it seems to install correctly. After i installed rEFIt it just has this cute little penguin sitting there. I rebooted and tried to go back to Ubuntu and the penguin still shows up but this time a black screen pops up and it asks me to insert a bootable device and press any key. I'm not sure why this is happening. This is probably the 5th time I've tried to install it. I've even used a different Ubuntu ISO but it still won't boot after the installation.

• How can I fix intermittent iSight camera functionality on a Macbook Pro 5,2?

  - by Mmmm

  I have a Macbook Pro 5,2 laptop dual booting OSX and Ubuntu. The built-in iSight video camera works only sporadically. By that I mean that sometimes if I boot and try to use the camera it does not work (most of the time) but other times it does. I don't have good repeatable data regarding when it does vs. when it doesn't other than to say that it always seems to work right after I upgrade to a new Linux kernel with the Update Manager and reboot, but then eventually stops working again until I upgrade the kernel again. That is hard to test repeatably, so it's hard to know for sure that that is the case. This has happened consistently with every version of Ubuntu from 10.10 through 11.10. I can get around this by booting into the OS/X partition, since all of the hardware obviously works perfectly on that side of things, but it would be great if I could remain in Ubuntu and do the same thing. Thanks in advance for any inSights.

• Truecrypted Windows 7 missing in Grub2 after upgrade

  - by user287545

  I have an encrypted dual boot Windows 7/Ubuntu System and upgraded my Ubuntu today. Everything went smooth but my Windows is not shown in the Grub2-List anymore. Starting up I have the Truecrypt Bootloader and after entering the Password I get to Grub (now Grub2). There my Windows 7 entry is missing now. Here is my report: http://paste.ubuntu.com/7569182/ Updating Grub did nothing to it. My guess is that within Ubuntu it does not recognize my Windows Installation on sda1 anymore. I can't mount it aswell. I can only mount it via Truecrypt itself. I think I might have to manually insert the menu item for Windows into that Grub config file. I guess that after entering the password in the truecrypt bootloader it would be possible to start Windows if the item was there - just a guess though. Edit: I basically followed these steps to set up my system: Dual Booting Windows 7 with Ubuntu 12.04LTS with Truecrypt

• new installation won't sync directories with my account

  - by barrydrake

  I had a dual-boot arrangement on my desktop with 12.04 and 12.10 (testing). Last week, I managed to trash both and ended up re-installing both. After doing all the updates, I activated Ubuntu-one which worked just fine on the previous installations. On both 12.04 and 12.10, the Ubuntu-One window fails to show the folders for syncing and only syncs the Ubuntu-One folder. Adding a folder on my net book on which sync is working properly brings up a pop up on my desktop that tells me a new folder is available for syncing - but the Ubuntu window fails to show it. I have put a screenshot from my net book (working OK) and one from my desktop which shows the problem. Any suggestions please?
