• Usb boot device totally unable to be formatted

  - by fuqda

  I'm really upset by now, I've been trying 2hours straight to format a stupid usb drive (I'm new to ubuntu and I dont know if I will last long at this rate) Basically this was the lubuntu boot usb key I tried to remove files with sudo rm I tried to format disk with disk utility I tried to format disk with gparted (with unmounting beforehand) NOTHING WORKS. I cant delete a file. I cant move a file to the usb key. I cant do anything. This is really infuriating.. I dont know what to do ? here are some gparted errors while trying to format to fat32 after unmounting error fsyncing/closing/dev/sdb: input/output error input/output error during write on /dev/sdb when I try to remove by hand, it says "read-only file"

• Download a file over an active SSH session

  - by Oli

  So I'm SSHed into my Ubuntu server from my Ubuntu desktop. I'm at a certain path and I want to download a file to my local filesystem (preferably the path I was at before I entered the SSH session). I could mount SSH and pull the file across by mouse but what if I was trying to get a root file and logging in by root directly is disallowed? Even if that wasn't the case (it isn't now), surely there must be a simple way of pulling back a file over an active SSH connection. Surely!

• Ubuntu 12.04 GNOME Terminal (3.4.1.1) Xorg 100% CPU

  - by EaZ

  after upgrading Ubuntu 11.04 to 12.04 (x64 arch) maximizing or resizing GNOME Terminal (3.4.1.1) windows larger cause the Xorg (1.11.3) or X process to utilize 100% CPU. Resizing smaller, moving windows or minimizing do not seem to have the same impact but by no means are snappy either. I'm running on a Dell E6500 laptop (upgraded from 11.04) running the nvidia proprietary drivers v. 295.49 (Quadro NVS 160M) with compiz 0.9.7.8. Other terminals such as xterm/uxterm are unaffected. Hoping it has to do with some configuration settings but not sure where to look (nvidia/compiz/gnome/X?). Thanks!

• Setting up lvm with HDD and SSD

  - by stonegrizzly

  My current hard drive is just about full and rather than just toss it and get a new one (since it works fine), I want to get a new drive and set them both up using lvm. While I'm at it, I also want to get an SSD to install the OS and applications on. This is my plan: Put / on the SSD (one partition) Put /tmp on a ram disk Put /var on a partition on my new drive Put /home on the rest of the new drive and my current drive using lvm. My goals are: Speed up boot time and application launch Minimize unnecessary writes to the SSD Never have to worry about which disk/partition to store my files on. I want the OS & lvm to take care of that Does this make sense? I'm fairly experienced with Ubuntu but I've never dealt with lvm before.

• Best book/source to learn the unix commands

  - by Kraken

  So I was intern at this company wherein they'd use just putty. Now I've never worked with unix commands, apart from the basic , compile code , run C code. But now I would love to know all the things about the unix. Starting off with the commands, from the most basic of all to the decent level. Also, moving forward, how the different folders/files are arranged in a unix (ubuntu is installed on my system) system. I have picked up a couple of books, but they dont seem to help. Can someone suggest a comprehensive book that'll fulfill my needs. Because, working with a GUI on ubuntu does not really give me the real feel of things. Hence I'd want to move on to the terminal instead. Thanks.

• restore window sizes, drag and drop functionalty in Unity (a simple use case)

  - by Avetik Topchyan

  Once application is maximized (say "Cheese") how can I restore its size back to the original? Is it possible to drag-and-drop from one application to another application in Unity? If so, how can I do that? Suppose I have a Rhythmbox open and I would like to drag a picture from a Desktop location (actually where is it?) to Rhythmbox album art section in the lower left corner? Unity was poorly designed, IMHO.

• Binfmt config not persisting after booting

  - by Ishpeck

  I have the binfmt kernel module set up so I can run .NET apps as if they were native binaries. I have the /etc/rc.local file configured identically to this. If I power down my computer or boot into Windows, when I come back to Ubuntu, I can't run .NET apps without calling Mono. However, if I simply touch /etc/rc.local and restart, the binfmt configuration appears to kick in and I can run my .NET EXE's as I expect to. How do I get my configuration to stick?

• AMD Catalyst Beta Open Source Drivers

  - by FourZer0

  I'm a gamer with a pretty low-end computer, so I always update to the beta drivers to squeeze out every bit of performance I can get. I currently have 13.3 installed, but I want to install the 14.6 beta. I want to use the open source version, instead of downloading from AMD's website. How can I do that in the terminal? And please explain what the commands mean so I can do it on my own in the future. Thanks in advance!

• Unable to record from USB sound card line-in connector

  - by tete

  I've been googling and struggling with this for a while but haven't been able to make this work. I bought a USB sound card (Encore ENMAB 8-CM) to record from its line-in connector. I'm not sure which input to pick in Audicity, but I'me sure I've tested them all. These are all the available inputs I have in Audacity. But there's no sound being recorded at all. I've already checked the device is working, so I really don't know if I'm doing something wrong. Any help will be very appreciated. Cheers.

• Login Screen hangs after entering password

  - by Ravi

  When I enter my password in the login box nothing happens. It gets stuck. It was running fine earlier. I have installed gnome-panel and cairo-dock, after which, I logged out, logged back in, and choose gnome classic session. I also added a ppa from the webupd8.org to install the themes (link). I opened Ubuntu Tweak tool, and changed the theme to Evolve the whole laptop stopped responding. The keyboard and mouse were unresponsive. So I was forced to do a shut down. Now whenever it starts, I cannot login into Ubuntu. I hear the fan noise, as its spinning very fast, when the laptop freezes.(Probably the CPU is running at 100%). Please help me. How can I login back to Ubuntu? I am using Ubuntu 12.04 and have installed all the latest updates.. EDIT: I want to know how can I delete a folder from the file system using the live CD?

• How do I install ubuntu 12.04 over windows HP

  - by Cakemix

  I have an HP Desktop AMD 64 6-core processor 10GB RAM 1.5TB HDD and Windows 7 installed. I downloaded the 12.04 ISO and burned to a DVD. I want to install Ubuntu over Windows. I have recovery CD's made in case Ubuntu isn't for me and my family. During the install it says No root file system is defined please correct this from the partitioning table. In the box where I should be able to choose a partition, none are available to choose from, it is blank. I know that HP has decided to use 4 partitions. How do I go about deleting all the partitions using the LiveCD? I've never used GParted before and am a bit lost when it comes to anything to do with partitions.

• Can someone explain why Chromium is difficult to build for Ubuntu?

  - by vasa1

  I hope this question is not regarded as a duplicate of Does someone know why the Chromium daily package isn't build anymore? because that question relates to daily builds and not to "stable" Chromium available from the Software Center. So what are the technical difficulties that the Chromium team is facing? A very similar question has been asked in Default Browser Follow-up. I would very much to have an updated Chromium stable on my system. Also, is the problem of building Chromium restricted to 32-bit versions? (I have a 64-bit CPU but just 4 GB RAM and so I'm staying with 32-bit all the way.) I'm asking this partly in the light of the discussions, here for example, about having Chromium as the default web browser in future releases.

• Where I can I find Zentyal ?

  I'm using Ubuntu 10.10 Maverick. Does anyone know where I can find a version of Zentyal for it? I heard that webmin is not available any more, and I had a problem with it, so I'm trying to change the webmin to Zentyal. The problem now is that I can only find the version for Ubuntu 10.04 (Lucid). I'm having a problem with connection speed, which is why I need Zentyal to help me configure squid to cache the webpage for faster loading.

• Windows Wireless Drivers - Install

  - by Justin Y.

  I have nearly ended my journey of making a dual-boot windows xp and ubuntu computer. Along with version 12.04, came the problem with my NetGear WNDA3100v2 wireless adapter. It wasn't compatible. My last step in my adventure is to install the software called Windows Wireless Drivers. I have internet access on my laptop and a flash drive. It would be preferable to receive a link to this program, because I see no link on the website, and I can't download it from the Ubuntu Software Center. Thanks.

• How can I get the touch screen working on a motion computing m1400

  - by pgcudahy

  I picked up a motion computing m1400 for cheap and was successful in getting 11.04 installed on it but have run into trouble getting the touch screen to work. This is one of the older tablet pcs that need a special pen for the touch screen. There are instructions out there for older versions of Ubuntu but they usually rely on a package called wacom-tools that is no longer in the repos. Is there any support for these old tablets or has time passed them by?

Anyways, when I upgraded and tried to create a shortcut from the launcher it reported this, "The application launcher "libreoffice3.5-base.desktop" has not been marked as trusted. If you do not know the source of this file, launching it may be unsafe." Any ideas of fixing this. Thanks in advance: Regards

• Broadcom 4313 doesn't work following 12.04 upgrade

  - by Lucas

  I have an hp G62-228Ca laptop with a BCM4313 previously running Ubuntu 11.10. I ran the 12.04 upgrade last night without much thought. Following the upgrade and mandatory reboot, the wireless card no longer shows up in the network manager, the first time I've had any kind of issues with wireless under Ubuntu. I've done much Googling on the issue but so far I haven't found a permanent solution. Mucking around with some packages though (I've installed five different ones or so), I've managed to devise a workaround that I must run every time I boot the laptop. I have to remove the Broadcom STA driver and reinstall it. Inspiration taken from here: WiFi does not work, Broadcom STA Wireless driver does not work on a BCM4313 After the second modprobe command, the wireless reappears in the network manager and ten seconds after that I'm back on the wifi. If anyone can provide some advice on how to fix this permanently I will be extremely grateful. I'd rather not roll back to 11.10 or reinstall, but I will if I need to. Just let me know if you need the output from any terminal commands. Thanks in advance!
