• Problem with setting up a bootable USB on corrupted OSX

  - by Nick

  I cant access the desktop because my harddrive is corrupted. Therefore I want to make a bootable USB stick so i can transfer all of my important files to my External HD. Problem is that Im stuck on Step 3 --- http://www.ubuntu.com/download/help/create-a-usb-stick-on-mac-osx . Im not sure of what i should change this to: hdiutil convert -format UDRW -o ~/path/to/target.img ~/path/to/ubuntu.iso It says convert failed - No such file or directory. Obviously the problem is that i dont know the path to the USB, maybe you know how to find out? Please help me. Thanks. ps. Ive downloaded the ubuntu desktop amd64+mac. pps. Unetbootin is a different alternative, but i dont know if it works?

• An "Invoke Update Manager to update everything and shutdown" script after idle for x minutes?

  - by unknownthreat

  I have Ubuntu 10.10 installed on a machine for my parents. The thing is they never request updates from Update Manager even the manager itself prompted them so. Moreover, when they are done with whatever they are doing on Ubuntu, they always leave the computer on. And I always have to come back and shut the machine down. Sometimes, the computer even sit idle for hours. So I want to know whether this is possible in Ubuntu. I am thinking of a script that will be activated after the machine is idle for x minutes. When x minutes have elapsed, Update Manager will automatically update everything listed. (I recall that you need the admin password for this, so is there a workaround?) After all the updates are done, the machine will automatically shutdown. Is this possible?

• Where is the Accessibility mouse click lock?

  - by user10133

  I've been a user of Linux on the desktop off and on again over the years. I very nearly switched my primary computer to Ubuntu prior to the release of Windows 7. There were a few, but significant issues at the time that prevented wholesale adoption, mostly tethering with my phone and lousy VPN Client. One key component I could count on was the Accessibility features. I have recently installed Ubuntu 10.10 and am considering giving it another try, but it appears Ubuntu has taken a leap backwards in that it no longer has a click lock feature for the mouse. Basically I need the ability to press and hold the left button to trigger a locking of the button so I can move the mouse by way of a trackpoint with my prosthesis. I absolutely require this feature and it is a deal breaker if it won't work. I've tried the Dwell keys but this is a chaotic control at best. I've never been able to manage a drag of any kind.

• Can't mount data DVD using 12.04

  - by dash2

  I cannot mount a data DVD using Ubuntu 12.04. I can read the DVD using a different OS, so the DVD is not the problem. I can read other CDs using Ubuntu.

• Create secure working environment on USB stick

  - by Chris

  I want to create an usb stick which contains an ubuntu installation that: can be used as a working environment (Covered in: How do I install Ubuntu to a USB key?) - ie the ubuntu installation on the stick must provide an accessible home folder. Is completely encrypted. I intend to use it as a secure environment to work on sensitive customer data - and also need the system on the stick to be able to connect to the internet. How do I realize the complete usb stick encryption? I am also very thankfull for any further articles and ideas on this topic!

• How to get presentation tools like windows office without windows office?

  - by ved2254

  On working with MS Office and LibreOffice I found that (as countless have) Libreoffice is not quite up to Windows' level. I would like windows Office on Ubuntu but that means using Wine, which I don't want. I tried using wine but it went a teansy bit wrong (where i have no idea). So I tend to avoid it. Hence the question : Is there any way I can get any program/plugin/patch/anyting-I-missed to get same functionality as MS Office in Ubuntu? I have Ubuntu 12.04 64bit (if required).

• Just installed 12.04 and it freezes when I try logging in

  - by James

  I just installed Ubuntu 12.04 alongside Windows 7 on an Acer Aspire 1 with AMD Dual-Core C60, 4 GB RAM, and 320 GB HDD (100 GB partitioned for Ubuntu). After restarted my computer, I was able to log in fine but when I tried to log in again after shutting my netbook off, it began to freeze on the log in screen. The freezing occurs several seconds after I'm prompted to enter my password. Even if i enter the password before the freezing occurs, I end up getting stuck while it's loading or something. I'm new to Ubuntu so I have no idea what to do. Also, before it gets to the log in screen, it says something like this: NTFS5: No wubildr NTFS5: No wubildr NTFS5: error: "prefix" edit: it was wubildr, not unbilder. Also, the freezing seems to be inconsistent

• How to make/use launcher?

  - by prosseek

  In ubuntu, I can run firefox with the command firefox in Terminal, or click the button in dock or panel. How does this possible with ubuntu? I googled to find the name launcher, but I don't know exactly how does it work. Q1 : How to make launcher? If I make a GUI program, does that mean that I need to create launcher to start by clicking it? Q2 : Can I make a launcher for whatever program, even if it's not a GUI program? Q3 : How to link a launcher? How can make a link to a launcher in a Desktop to start a program? Q4 : The idea of launcher is unique to ubuntu? Or if I have one launcher, can I use it for other distributions? Q5 : Why some of the program pops up its icon in Docky (firefox for example), but some of the program doesn't (p4v for example) ?

• Debugging OpenOffice crashes

  - by JD Long

  This is partly an OpenOffice question and partly a Ubuntu question. I'm running OpenOffice 3.2.0 and Ubuntu 10.04. I get frequent crashes of OO, especially the Calc app, although I get crashes in the word processor as well. They are very abrupt and accompanies by no warning or error message. I'm just typing away and then the app is gone. Sometimes I even end up thinking I'm typing in OO and discover that OO has crashed and I'm typing in whatever application was under OO. However, I can't reproduce these crashes on demand. They seem random. I can open the same file and do the same exact thing but it does not crash. In Ubuntu how do I trace, track, or diagnose these types of crashes? Is there software I can invoke to help diagnose? Can I start OO from a command prompt with debugging of some sort enabled? Note: if someone could add the tag OpenOffice, I would appreciate it

• issue with older laptops

  - by Adam

  I recently reimaged my Lenovo t400 with Ubuntu. However, after wiping two other systems (Compaq Presario 2100 and Dell Latitude D600) both hUbuntu 11.10 and Ubuntu 12.04 fail to load on boot. I am concerned that there is some type of issue using Ubuntu on these older systems as every part of the process has been repeated/attempted several times in the same manner as practiced in the successful load of the newer Lenovo t400. I now have two laptops without an operating system as the discs/thumb drives that were formatted to load on these devices do not seem to work. I would appreciate any assistance that you may be able to provide. Regards, -Adam

• 12.10 on Elitebook 8560w w/ WUBI

  - by iSeth

  I am trying dual boot Windows 7 and Ubuntu on my Elitebook 8560w via WUBI. Between Microsoft and HP they used up all my primary partitions so I decided WUBI was the best way to go. It all goes smoothly until I reboot to finish the installation, then it hangs at copying files. It always freezes here: debconf (filter): widget found for ubiquity/install/title debconf (filter): -- 0 OK It also says something about "so and so might freeze best to kill it" but I didn't get it written down. Can anybody tell me what that means? EDIT: This is what it says (In Full): ubuntu kernel: [365.130914] [<c1064d607] ? kthread_freezable_should_stop+0x60/0x60 ubuntu kernel: [365.130914] [<c15d04fe7] kernel_thread_helper+0x6/0x10 debconf (filter): <-- progress set 49 debconf (filter): widget found for ubiquity/install/title debconf (filter): -- 0 OK debconf (filter): <-- progress set 50

• Mouse wheel scrolls down, but not up?

  - by HDave

  I've set up a new machine with Ubuntu 12.04 (x64) and have notice that the mouse wheel scrolls down fine, but when I scroll up, it pages down! I've run xev and have verified that scroll up is registering as button 4 and scoll down is button 5. So everything there is fine. I think that button 4 is somehow mapped to page down instead of scroll up. Any idea how to fix? NOTE: I've read the Ubuntu instructions on how to use imwheel to change mouse button mappings, but it doesn't work on 12.04. See here: https://bugs.launchpad.net/ubuntu/+source/imwheel/+bug/1004812

• Graphics card support

  - by Daryl

  Brand new user to Ubuntu and Linux. Quick question that I think already know the answer to: Does Ubuntu 11.10 have an updated driver for my graphics card? I was planning on being able to s-video out and watch videos on my tv like I could when I had Vista installed. daryl@daryl-Aspire-3050:~$ lspci -nn | grep VGA 01:05.0 VGA compatible controller [0300]: ATI Technologies Inc RS482 [Radeon Xpress 200M] [1002:5975] ATI Radeon Xpress 1100 is the actual card. As it is, Ubuntu is not recognizing when I plug an s-video cable into my laptop. I've narrowed it down to using what I think is a generic driver because all of the s-video enable commands I found and tried have failed.

• What are the files in /dev/input/ and what they do?

  - by Pouya

  I'm fairly new to ubuntu and I've started to search around everywhere and check everything! Recently I saw these files at /dev/input/eventX, js0, mice, mouseX. By printing the output using "cat" I realized they are somehow responsible for mouse and keyboard input but the output had an strange character encoding (even for the keyboard). My questions are, what are these files and how can I interpret the data of these files? Are there any other places that I can access the input/output of my Ubuntu machine? And are there any ebooks, manual or something similar that I can check the duty and structure of ubuntu system files? (i.e. to find the answer of such question)

• Closing lid freezes laptop

  - by trampster

  Closing the lid on my dell studio 15 which is running ubuntu 10.04 freezes the screen. This is a new problem in ubuntu 10.04 which did not exist in 9.10 I have tried playing with all the settings in System-Preferences-Screensaver but nothing seems to make any difference. (please note the Power Management settings are accessible from here so I have tried those too.) I don't need hibernate or suspend. I just want to be able to close the lid, and then open it and still have a working laptop. Is their a settings somewhere that will make Ubuntu ignore the lid closing?

• Boot Failure: No default or UI configuration directive found Normal install on laptop [closed]

  - by user79920

  I have had Ubuntu on my laptop for quite a while, it's just a standard install, no partitioning off, no wierdness of any other sort, just ubuntu. Today my computer started to lag really bad so I tried to restart it, but after bios loaded I just got an error that said "ERROR: No configuration file found No DEFAULT or UI configuration directive found!" After that it had "boot:" and a cursor, like it expects me to type something. Once again, this is just a normal install on my hard drive, not a VM or booting from USB. It's Ubuntu 12.04 on a Sony Vaio VGN-SZ240P Any help is appreciated!

• How to get an email notification when a USB storage device is inserted?

  - by karthick87

  We are running more than 600 Ubuntu systems in our company. It is a data centre so we have certain policies. We have disabled the usage of storage devices in all the Ubuntu systems. However we would like to configure email alerts. If someone inserts storage devices, we should get an email Alert with subject as below, Email Alert: STORAGE DEVICE FOUND on IP: 172.29.35.18 Note: Where as for Windows system, we have certain policies applied in our DC. So there is no problem with Windows system. We need to receive alerts for Ubuntu system also. Any way to accomplish the above task would be great.

• How to recover an interrupted 12.04 upgrade from 11.10?

  - by martin

  Ok, I will get right to the point. I was upgrading ubuntu to 12.04 from 11.10 (x64) and right in the middle of the package installation I had a freeze (not ubuntu's fault) forcing me to do a hard reset of my pc. Now the ubuntu installation is completely broken I can only get access via recovery mode. I already tried "apt-get update && apt-get upgrade" and the option to fix broken packages. Nothing changed. So I'm wondering if its possible to fix the broken packages, or maybe to restore before the upgrade? Thank you in advance.
