• How to install Ubuntu 12.04.1 in EFI mode with Encrypted LVM?

  - by g0lem

  I'm trying to properly install Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with the alternate install CD ".iso" on a lenovo Thinkpad X220. Default Hard Disk (with a pre-installed version of Windows 7) has been replaced with a brand new SSD. The UEFI BIOS of the lenovo Thinkpad X220 is set to "UEFI Boot only" & "USB UEFI BIOS Support" is enabled (I'm using an external USB DVD reader to perform Ubuntu installation). The BIOS is a Phoenix SecureCore Tiano, BIOS version is 8DET56WW (1.26). The attempts below are made with the UEFI BIOS settings described above. Here's what I've tried so far: Boot on a live GParted CD Create a GPT partition table Create a FAT32 partition for UEFI System, set the partition to "EF00" type ("boot" flag) Leave remaining space unformated Boot on Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with alternate CD: Perform the install with network updates enabled Use manual partitioning FAT32 partition created with GParted is used as "EFI System partition" Remaining space is set to be used as "Physical volume for LVM" Then "Configure encrypted volumes" using the previous "Physical volume for LVM" as the encrypted container, passphrase is setup. "Configure the Logical Volume Manager" creating a volume Group using the encrypted container /dev/mapper/sda2_crypt Creation of the Logical Volumes "Create logical volume", choosing the previously created volume Group Assign a mount point and file system to the Logical volumes : LV-root for / LV-var for /var LV-usr for /usr LV-usr-local for /usr/local LV-swap for swap LV-home for /home NOTE: /tmp would be in RAM only using TMPFS Bootloader step: neither my ESP partition (/dev/sda1, /dev/sda or MBR) seems to be the right place for GRUB, I get the following message (X suffix is for demonstration only): unable to install grub in /dev/sdaX Executing 'grub-install /dev/sdaX' failed This is a fatal error. Finish installation without the Bootloader & Reboot The system doesn't start, there's no EFI/GRUB menu at startup. What are the steps to perform a clean and working installation of Ubuntu 12.04.1 Precise Pangolin, 64bit version in U(EFI) mode using the encrypted LUKS + LVM scheme described above?

• Transferring ratings and playlists from Rhythmbox to Clementine

  - by xpanta

  After the latest update, Rhythmbox (which was my main mp3 player on my Ubuntu Latest distro) stopped functioning: it dies just after startup. So, I turned to Clementine which I like a lot. However in Rhythmbox I had my playlists and ratings. Song ratings are very important to me because many of my auto-playlists are depending on them. Is there anyway I can get my playlists and ratings from Rhythmbox and add them to Clementine? Thanks.

• Ubuntu 12.04 shut down freezes

  - by sam

  I am using Ubuntu 12.04 for last one month without any problem. It was upgraded from Ubuntu 10.10. Recently I needed to replace my hard disk. After replacement I installed Windows 7 and Ubuntu 12.04 on the system. For some days it went ok, but now shutting down from Ubuntu is causing problems. It freezes on the text screen saying acpid=exiting checking for running unattended upgrades. After that I waited for a long time, but it didn't go off and I had to hit ctrl+alt+del to restart the system and booting from Windows and then shutting down from there. This happens every time I shut down my system from Ubuntu. I have seen many posts regarding the same kind of issues but none of the solutions reported there helped me out.

• Ubuntu 13.10 upgraded from 13.04 issues

  - by Andrew Sadach

  The keyboard stopped working after a while, I started using 13.04 again VIA USB because I am waiting for the keyboard issues that 13.10 has to get an update. 13.04 had tons of issues I didn't care about because most of it worked. Now almost none of it works. There's even a huge amount of graphical errors. Others have had these issues I've noticed while looking at the similar questions area next to this text box, but my question is can I downgrade 13.10 to 13.04?

• Ubuntu 12.10 with kernel 3.5.0-18 failing to boot

  - by Chaitanya

  I had 12.04 with kernel 3.0.2. Today I have updated my system and got 12.10 with kernel 3.5.0-18. Now when I boot my machine with 3.5 kernel, it starts until the page where I enter my password. Within seconds, I get a page with looooong list of some commands or list. I can't take screen-shot of that. It looks something like: [1.2234978942837]kjsahfa;lsfksld;fkjsf;owieurwirejw/rnw;erkjwelrjw2309480432 [1.3294823498230948]as;lfjsf;iuwrijrwjlkerjw;rekwer;lkwjre;lkjRIJWEORIWE'JJA; Luckily, in my boot page, I have 3.0.2 kernel also. When I boot with 3.0.2 kernel there is no problem. But when I boot with 3.5.0, it throws that weird error. I wont be able to do anything at that time. None of the keys work. I have to forcibly shutdown the machine and restart with 3.0.2 kernel. Please help.

• Ubuntu12.10 not installing on new computer?

  - by Joshua

  I'm trying to Install the latest 12.10 Desktop. I have burned the iso file onto a DVD using an ISO burner. I then reboot my computer, and use the boot menu, I choose the DVD and it asks me if I want to try it, install it, or check for defects. Whichever one I choose my screen goes blank and for a bit you can hear my DVD burner, but then it stops and the screen goes completely blank and doesn't so anything. I am using a new HP Pavilion model P7-1455 running windows 8. What is wrong? How can I fix this?

• Ubuntu 14.04 key arrow up is being pressed by itself

  - by Margo Nikolopoulou

  Keyboard's up arrow key is keep pressing itself every few seconds. I tried to install Ubuntu 14.04 via boot cd, even before installation the arrow key was being pressed by itself. I tried to use Ubuntu first without installing it and then tried to install it from there, the issue seemed to be fixed. I was using the PC for months until out of the blue the issue came back. IT IS NOT A HARDWARE ISSUE! Thank you in advance.

• forward sudo verification

  - by Timo Kluck

  I often use the following construct for building and installing a tarball: sudo -v && make && sudo make install which will allow me to enter my password immediately and have everything done unattended. This works well except in the rare case that building takes longer than the sudo timeout, which may happen on my rather slow machine with large projects (even when using make -j4). But when the build takes a long time, that's exactly when doing things unattended has a great advantage. Can anyone think of a shell construct that allows me to input my password immediately, and which has make executing under normal permissions and make install under elevated permissions? For security reasons, I don't want to configure my user to use sudo without password. A viable option is to set the timeout to very long, but I'm hoping for something more elegant.

• Lubuntu from USB

  - by WGCman

  I have An Acer Aspire 1362 Laptop with AMD Sompron 2800+ processor and only 256MB RAM, with Windows XP installed. I have downloaded Lubuntu-12.04-alternate-i386.iso and installed it to a 16GB USB stick. I do not want to install Lubuntu on my hard drive (yet!). I have got the USB stick to boot, and am working my way through the menu. At one stage, the installer wants to partition my hard drive, so I abort the installation. There doesn't seem to be an option on the menu to boot and run Lubuntu from the USB stick without putting stuff on the hard drive. How can I achieve this, please?

• To make or not to make...python-nautilus a dependency?

  - by George Edison

  That is the question! Okay, all silliness aside, I really am forced to make a difficult decision here. My application is written in C++ and allows other scripts to invoke methods via XML-RPC. One of these scripts is a Nautilus extension written in Python. The extension is packaged with the rest of the application and copied to the appropriate place when installed (/usr/share/nautilus-python/extensions). Now the problem is that the Nautilus extension requires the python-nautilus package to be installed to be operational. So therefore I have three options: Make the python-nautilus package a dependency. This option will ensure that anyone who installs my package will be able to use the Nautilus extension. However, this option will not be attractive to XFCE or KDE users - a ton of python-nautilus's dependencies will be installed on their machines and take up a lot of space - even if they never use Nautilus. Put the python-nautilus package in the suggests: or recommends: field. This option provides the end-user with a way to avoid installing the python-nautilus package (by providing the --no-install-suggests or --no-install-recommends argument to apt-get). However, this won't work when the user installs the package in the Software Center. (I always get mixed up as to which of those two fields are installed by default.) Prompt the user when the application is installed or first launched. This option is more complicated than the others but offers the best compromise between making it easy for the user to install python-nautilus (without going into a technical explanation) and not installing it when the user doesn't need it (or want it). I guess the best way to implement this is a simple prompt that invokes apt-get if the user would like the package installed. Don't install the package at all. This option ensures that nobody has python-nautilus installed on their machine unless they want it. However, this also means that my Nautilus extension will simply not run on the end-user's machine unless they manually install the package. Which of these options seems the best choice? Have I missed any pros and cons for each of the options?

• USB Keyboard doesn't work in Ubuntu 14.04

  - by Steven Crossan

  My USB keyboard isn't working in Ubuntu 14.04, but also didn't work in 13.10. I upgraded today in the hope that the issue would be resolved, but it wasn't. The keyboard works in BIOS and GRUB but stops working when I reach the login screen. It is detected by the system, but just doesn't work.

• Why doesn't unity show icons or panel after installing numix theme?

  - by Sid

  I'm a beginner to Ubuntu/Linux and I have a problem: Unity is not loading! When I choose Unity in the log-in screen, I get notifications and I can see the mouse, but that's it. I have Ubuntu 14.04 installed, along with Bumblebee/Primus. I had no issues whatsoever, until I decided to try the numix-theme and the numix icon pack. I added the PPA and installed it, but when I logged off and logged back on, nothing showed up. I panicked, and in tty1, I purged numix-* but that did not solve the issue. To get by day-to-day use, I installed gnome-flashback, and among those environments, only the metacity one works. (The compiz one does not.) I've tried installing the unity-tweak-tool to reset unit, installing dconf and doing: dconf reset -f /org/compiz/ but that didn't work either. One site even told me to delete /org/compiz/, but that did not resolve the issue. When I checked ccsm, the Unity plugin had a check to it. I also tried with Unity doesn't load, no Launcher, no Dash appears, but it gets stuck on "loading icons". Any help will be awesome!

• How do I rename a mounted Truecrypt volume?

  - by invert

  When I mount the Truecrypt file on my USB drive it shows up as truecrypt1. The volume is FAT, using mtools to rename a volume label involves e2label /dev/sdbx, however truecrypt1 does not map to a physical partition. fdisk -l does not show the volume partition (only the physical USB device), and df -h lists the volume path as /dev/mapper/truecrypt1. Finally, using the Nautilus 'Rename' context action, gives the error: "Sorry, could not rename "truecrypt1" to "towel": Operation not supported by backend". Apparently this can be done in Win, but how can I rename this volume in Ubuntu? As Nicolas said, specifying the mount point names the partition the same. The truecrypt GUI does not remember the mount point I set, so I specify the mount points in a script which I placed in my main menu. #!/bin/bash gksudo truecrypt /media/usbdrive/encryptedfile /media/securedata/

• Ubuntu 12.04 wired ethernet not working and wireless not working, How do I fix it?

  - by Eloy

  I am new to ubuntu. I recently installed the latest ubuntu for desktop from http://www.ubuntu.com/download. I was very excited to start using ubuntu until I booted the computer and saw that i couldn't connect to the internet at all. I have spent hours trying to figure this out. I keep running into people suggesting installing drivers etc. I have tried about everything and nothing seems to work. I have the ethernet cable connected to the computer but it doesn't recognize it. I ran the following: lspci | grep -i eth and I get this 09:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5752 Gigabit Ethernet PCI Express (rev 02) Any help would be much appreciated. I am kind of bummed I have spent all this time tyring to get the internet to work and haven't even gotten to use the power of ubuntu Update copied from comment: Changing the Ethernet cable to a different one fixed the problem.

• xubuntu 12.04 can't change desktop background/wallpaper permanently

  - by Frank

  If I change the desktop background (wallpaper) via right-click on desktop = desktop settings = single image, and select another background image from the list, or add a photo of my own (via the "+" symbol), I can actually change the background image, but after logging out or restarting, the wallpaper is always reset to the original xubuntu 12.04 background. So, basically, I can't find a way to permanently change the desktop background. Any ideas?

• Effect of using dedicated NVidia card instead of Intel HD4000

  - by Sman789

  Short version: Can someone please advise me of the effect of adding a dedicated NVIDIA GeForce GT 630M card to an Ubuntu laptop in terms of power consumption and performance gains/losses when doing general productivity tasks and booting up. Also, how good are the closed source, open source, and Bumblebee drivers for these newer cards compared to support for the Intel HD4000? Long version/Background, if any info here is helpful: I'm thinking of ordering a laptop from PC Specialist (a UK company who actually sell machines without Windows pre-installed) with the following specifications: Genesis IV: 15.6" AUO Matte 95% Gamut LED Widescreen (1920x1080) Intel® Core™i5 Dual Core Mobile Processor i5-3210M (2.50GHz) 3MB 4GB SAMSUNG 1600MHz SODIMM DDR3 MEMORY (1 x 4GB) 120GB INTEL® 520 SERIES SSD, SATA 6 Gb/s (upto 550MB/sR | 520MB/sW) Intel 2 Channel High Definition Audio + MIC/Headphone Jack GIGABIT LAN & WIRELESS INTEL® N135 802.11N (150Mbps) + BLUETOOTH Now, as I want this laptop mainly for work and not for games, I would be more than content with the HD4000 integrated chip which comes with the processor. However, for compatibility reasons, I am not able to get the specs I want unless I choose a NVIDIA GeForce GT 630M 1GB graphics card, which I don't have a great deal of use for. I'm willing to buy it, however, as it's still cheaper than any other laptop with the specs I want. However, I know that Linux power management isn't fantastic with open-source graphics drivers, and I don't much about Bumblebee. Basically, whilst I'm happy to 'tolerate' the card being there, I don't want to experience any negative effects on the rest of my system (battery, performance etc) and if there are likely to be any, I might reconsider my purchase. So if anyone can advise me on the effects, I would be very grateful, since I doubt I can just turn the card off. Thankyou for any assistance :)

• Thinkpad W510 with default graphics drivers shows weird brightness issues

  - by Chantz

  Hey guys, I am currently running 10.10 - 32 bit on a new Thinkpad W510 with nVidia Quadro FX 880M graphics card. I am running with the default graphics drivers that installed with ubuntu install. My problem is that when I am logging in the screen acts normally as far as birghtness is concerned. I can increase/decrease brightness with Fn keys. But few seconds after I log in screen goes pitch dark. Hitting Fn+Home flickers the screen to all the way bright, then all the way dark. This behavior continues until I reach maximum brightness, in which case the screen stays all the way bright, for a few more seconds and then again goes dark if there is no activity & the cycle continues. Have you guys faced any of these issues? If so any pointers on how to resolve it. I am not alone, on ubuntu forum I saw another person having the same issue - link but no solution. Please help! UPDATE I followed the instructions that htorque mentions in his answer and it worked.

• Cannot read from 2nd SATA data drive connected via SATA docking station

  - by Robbo

  Installed 10.10 this week on dual boot system. Everything else works fine but cannot read from 2nd SATA drive with all my data. Same drive works normally when booted to Windows XP. Interesting part is that I can see the drive in Ubuntu Disk Manager, can read all its attributes, can test it, shows up in Disk Manager, Storage Device Manager and Mount Manager, and can mount it, even change attributes; it appears healthy but does not show up in "Computer" or anywhere else that it can be accessed. The drive is connected via an external e-SATA docking station which is connected to a SATA port on the motherboard.

• How can I set 'Print to File' as my default printing option?

  - by edm

  At the moment when I print, my Deskjet-3050 is selected as the default printer. I would like 'Print to File' to be the default 'printer' without using cups-pdf I specifically do not want to use cups-pdf because of the way it renders text (see below). I am not entirely sure what it is doing but it seems as though it renders the text as bitmaps and embeds them in pdf (as I am not able to highlight/copy/search embedded text as I am using a standard Print to File pdf). N.B. this is not a dupe of: Can I make PDF the default for 'print to file'

• Why does tomcat-admin install require adding admin and manager to tomcat-users.xml manually?

  - by J G

  I installed tomcat6 on lucid using apt-get. All working. I installed tomcat-admin. Not working. I amended the /etc/tomcat6/tomcat-users.xml file to uncomment the users and roles (from the default) to be like the following: <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="password" roles="tomcat"/> <user username="both" password="password" roles="tomcat,role1"/> <user username="role1" password="password" roles="role1"/> This still didn't work. Then from the following page I added. <role rolename="manager"/> <user username="admin" password="secret" roles="manager"/> then it worked. Why doesn't this occur as part of the install? (Why isn't this in the Ubuntu Manual on Tomcat ?)

• Upgrade with backports installed

  - by deshmukh

  I am running Ubuntu 12.04 with backports for TexLive. Ubuntu 12.10 is to contain the same version of TexLive that backport provides currently to 12.04. I, of course, want to move from backport to the normal version of TexLive available in Ubuntu 12.10 repositories. How do I handle the situation? Do I upgrade the normal way and everything will be taken care of i.e. my TexLive installation will now be from repositories instead of backports?
