• Macbook Pro 13" Retina (10,2): Keyboard and Touchpad don't work

  - by Dirk

  I'm dealing with Ubuntu since about 5 years and installed it on several laptops. Now I'm stuck when trying to install Ubuntu 12.04.1 on a brand new Macbook Pro 13" Retina (10,2). I sucessfully can start Ubuntu from an USB stick, the Ubuntu desktop is visible, a mouse cursor is visible. But there is no respond to keyboard or touchpad input. So I cannot really install Ubuntu on the Macbook. The details of my approach: Prepare an empty USB stick Download "ISO 2 USB EFI Booter for Mac" and copy the file bootX64.efi to the USB drive as /efi/boot/bootX64.efi. Download Ubuntu 12.04.1 Desktop for Mac from http://cdimage.ubuntu.com/releases/1-amd64+mac.iso and copy the iso the USB drive as /efi/boot/boot.iso Put the USB stick into the Macbook Press and hold the "alt" button while switching the Macbook on Select "EFI Boot" from the boot menu that appears and press the Return / Enter key Immediately a black terminal screen appears with the headline "Welcome to the Ubuntu ISO << - EFI booter". 30 seconds later the familiar Ubuntu startup graphics screen is showing. Further 20 seconds later Ubuntu has started and the desktop is visible - in wonderfully fine resolution Now the computer does not respond to any actions on the touchpad nor the keyboard Who did install Ubuntu on this Macbook Pro 13" Retina (10,2) successfully? On this site https://help.ubuntu.com/community/MacBookPro this unit is not listed yet, anyway. Any help would be greatly appreciated! Dirk

• sqlite3 timestamp (current_timestamp) one hour off

  - by Eiriks

  I run a small crawler on a virtual ubuntu server, initiated by crontab hourly. Datetime is inserted by defaulting the date filed to TIMESTAMP DEFAULT CURRENT_TIMESTAMP. Table creation looks like this: CREATE TABLE links (page TEXT, link TEXT, date TIMESTAMP DEFAULT CURRENT_TIMESTAMP, PRIMARY KEY(page,link)); The datetime gets stored fine, but it one hour off (one hour behind) Norwegian time (GMT +1). The server is located where-ever, I just need it to be on GMT+1. By typing datein the ssh session I get: Wed Dec 19 17:26:02 CET 2012 and that is correct (just now). So where does sqlite3 get it's time from? What must I do to set the time so that sqlite3 gets the time right?

• How to make "xset s off" survive a reboot (12.04)

  - by matteo

  On an almost-fresh install of Ubuntu 12.04, after disabling screen turning off, screen lock, and suspension on inactivity from all the (two) places one can find under Ubuntu's System Settings, the screen still turns black after some minutes of inactivity. I can't tell for sure whether it only becomes blank/black or turns off. I've uninstalled gnome-screensaver, which didn't change anything. Of the several answers I found out there (most of which I didn't try because they were either unclear or reported to not work for everybody), I tried one that DID work: sudo xset s off after which I left the computer unattended for hours and the screen never turned black, so it definitely worked. HOWEVER it does not survive a reboot. After reboot, screen starts turning black again after N minutes of inactivity. Given that "xset s off" does work until reboot, how do I make that setting permanent? I guess I could create a script that runs at startup issuing that command, but I think that would be a horrible hack and there should be a cleaner way to accomplish this.

• Deploying war files in tomcat6

  - by user3215

  I am using tomcat5.5 for a long on ubuntu servers 8.10 and 9.10 and '/usr/share/tomcat/webapps/' is the path where I place my .war files and access them on the browser over network. On a sytem I've installed tomcat6 and I'm failing to find that where do I place my .war file of tomcat6's webapps. I checked deploying war under /var/lib/tomcat6/webapps/ and the war file is extracted and I think this should be the location but I could not access the page when I tried http://serverip:8080/myapp. I could access the default page properly when I navigate to http://serverip:8080. The same war file is working fine on tomcat servers which were not installed from apt repository.

• Black & White screen after resuming from Suspend [Ubuntu 12.04]

  - by Rakatash

  I recently thought of giving Linux a try with Ubuntu 12.04. So far I managed to figure out how to troubleshoot and fix some of my older issues. But i wasnt able to find a problem similar to mine. The issue is, whenever my laptop starts up after suspend, the screen stays black for a short while. then after that comes a black and white 8-bit kinda screen with nothing else. I am not sure if it's an issue with the graphic card or not. because I am able to write my login password and proceed normally if i wait till this screen shows up...after that everything is displayed normally. is there a fix for this?

• Chromium stays in backgound

  - by Alexander Wada

  I'm running Thunderbird 31.0, FireFox 13.0 and Chromium 36.0.1985.143 on Ubuntu 14.04. Both Thunderbird and Chromium are open and running. When I click on a link in an email in Thunderbird I expected to switch from Thunderbird to Chromium to the foreground to display the website associated with the link. What happens instead is that Chromium wiggles in the Launcher and Thunderbird is still displayed. I have to click on Chromium to see the website. I don't have this problem with FireFox 13.0. Is this normal behaviour with Chromium on Ubuntu or can you change this so that you switch from Thunderbird to Chromium automatically?

• Setting user's group and umask has no effect

  - by Andrew Vit

  I'm trying to allow my "deploy" user to have access to files created by www-data: I added "deploy" to the www-data group. I set umask to 002. When I run the following commands, I'm not seeing the result I expect: deploy@ubuntu-lucid-32-generic:/var/www$ groups www-data adm dialout cdrom plugdev lpadmin sambashare admin deploy sysadmin deploy@ubuntu-lucid-32-generic:/var/www$ newgrp www-data deploy@ubuntu-lucid-32-generic:/var/www$ umask 0002 deploy@ubuntu-lucid-32-generic:/var/www$ mkdir test deploy@ubuntu-lucid-32-generic:/var/www$ ls -la test total 0 drwxr-xr-x 1 deploy deploy 68 Nov 7 20:37 . drwxr-xr-x 1 deploy deploy 476 Nov 7 20:37 .. I see that: The folder doesn't belong to the www-data group. The folder permissions don't have group-write (775). Note that the /var/www directory is owned by the deploy user: drwxr-xr-x 1 deploy deploy 510 Nov 7 20:45 . How can I give www-data selective access to directories? Or, how to share the /var/www directory with my deploy user: I don't care who owns it, as long as I can write to it, and so can www-data. (Ideally I would set up a directory with SGID access for www-data.)

• Can't install Apache 2.2.22 on Ubuntu 13.10

  - by B18C1

  My work environment requires Apache 2.2.22 instead of the latest version of 2.4. My machine is currently running Ubuntu 13.10. When I use Synaptic or apt-get it will not allow me to choose an older version of Apache than 2.4. So my question is, how can I force an install of Apache 2.2.22 on Ubuntu 13.10 using Synaptic or apt-get. When I do try to specify the version I get the following: sudo apt-get install apache2=2.2.22-1ubuntu1 [sudo] password for b18c1: Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: apache2 : Depends: apache2-mpm-worker (= 2.2.22-1ubuntu1) but it is not going to installed or apache2-mpm-prefork (= 2.2.22-1ubuntu1) but it is not going to be installed or apache2-mpm-event (= 2.2.22-1ubuntu1) but it is not going to be installed or apache2-mpm-itk (= 2.2.22-1ubuntu1) but it is not going to be installed Depends: apache2.2-common (= 2.2.22-1ubuntu1) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

• Apps missing in Software Centre

  - by Hahn Do

  I'm using Elementary OS Luna beta 1, based on Ubuntu 12.04 Precise. I used to used Quantal, as I remember there were roughly 68000 apps. Massive commercial apps, and the banner on top shows new hot apps all the time. Now I switch to Elementary because Compiz sucks with Nvidia. However, Software Centre now only has 41000 apps. No commercial apps, no 3rd party apps. I'm pretty sure I have all the sources enabled: My sources.list: http://paste.ubuntu.com/1396213/

• Unity desktop became transparent after installing VBox Guest Additions [closed]

• Ubuntu - Install Mate Desktop - Themes missing?

  I just installed Mate on top of Ubuntu by the following commands: sudo add-apt-repository "deb http://packages.mate-desktop.org/repo/ubuntu oneiric main" sudo apt-get update sudo apt-get install mate-archive-keyring sudo apt-get update sudo apt-get install mate-core sudo apt-get install mate-desktop-environment Which caused no problems, but many things (window theme, Mint menu, ...) are missing. It looks like: But it should look like: How can I install the missing packages?

• Cloning (mirroring) laptop display to area of external monitor display

  - by intuited

  I'm using Maverick "10.10" Meercat on a HP Pavilion tx2110. This machine has an NVidia Go6150 graphics card, and sports a 1280x800 display. I have an external monitor which can do 1280x1024 resolution. FWIW I'm using openbox as my window manager; as I understand it this shouldn't be a factor. I'd like to clone the display to the monitor, so that the size of the desktop remains at 1280x800, and there is a horizontal blank area on the external monitor. I.E. I want to avoid having to pan the display of the desktop on either monitor. So the actual resolution of the monitor would be 1280x1024, but the resolution of the section of the monitor where stuff was actually being displayed would be 1280x800. Using the nvidia-settings applet, I'm able to set up the cloned display so that the desktop size is 1280x1024 (the resolution of the external monitor), but can't find a way to instead have the desktop size stay at the resolution of the laptop's built-in display. Is this achievable? Ideally I'd like the external monitor's blank area to be at the top of the screen, i.e. for it to align the display with the bottom of the screen.

• Do I need to replace my hard disk?

  - by Sneha Kamath

  Hello everyone. Whenever I start my computer Ubuntu pops up the following error: A hard disk may be failing one or more hard disk report health problems A friend of mine ran some test and it was found that my hard disk has 74 bad sectors. Is this merely a software issue that will be solved after a complete format of my hard disk, or is it a hardware issue and I will have to replace my hard disk? Awaiting your responses. Thanks, Sneha Kamath.

• Slowdowns while using Firefox

  - by aneal

  I have Windows 7 and Natty installed on my computer. There is no problem on Windows 7's side, but whenever I log into Natty, it slows down while using Firefox 4. I tried it in normal mode using Unity and classic mode. However, the result is the same: it slows down e.g. when I scroll, it takes time to get effect, and also when I click other tabs, it takes time to active them. Moreover I cannot type properly, due to the lag. I don't know what the problem is?

• rsnapshot for remote backups...

  - by Patrick

  I want to use rsnapshot to make backups from my production server to a remote backups server. Should I install rsnapshot on the remote backup server and not the production one, right ? rsnapshot is going to pull the files to backup from the production server and store them locally on the backup server ? I've just realized that I don't have sudo privilegies on the backup server. Does this mean I cannot use rsnapshot for remote backups ? thanks

• Ubuntu 12.04-2 does not install with UEFI

  - by Rodrigo

  I'm in trouble to instal Ubuntu in Insipiron 14z. I've already created this question (that was wrongly marked as duplicated): First question But, the error seems to be with UEFI. If I disable UEFI on BIOS Setup, I can get into installation process of Ubuntu normally. But, I didn't finish the installation process because I think that will screw Windows 8 installation. So my questions is: Ubuntu installation should work with UEFI. So, why it didn't? Knowing that the error is with UEFI. I can forget the errors listed here?

• How to install compat-drivers or compat-wireless

  - by Sasho

  Could someone please explain me in detail how to install some of this drivers. I am running Ubuntu 12.04.2 and have the infamous (as I see everywhere in the net) problem with Atheros AR9462 wifi card. I tried everything to fix it and compat drivers are the only solution that I haven't tried. I tried to install some random package from kernel.org site and it couldn't make the driver (it threw some error). Then I updated the kernel to 3.10-rc7 and downloaded the last release of compat drivers and again the same problem occured. I reinstalled Ubuntu 12.04.2 and now I am using the 3.5 kernel because I don't know if rc7 is stable version. So my question is which compat wireless or compat drivers to download for this kernel and what is the process of installing. I tried with some command from the repository and it returned that it's not found. PS I am new to Ubuntu and Linux in general so explaining at length the install process and which driver I should install would be appreciated.

• Remove gradients from elementary theme?

  - by John

  I really don't like the gradients in the elementary theme, and I was wondering if there were a way to remove them, from applications like Nautilus-Elementary, Postler, Dexter, etc. I've tried commenting out the Apps/[Application].rc in /usr/share/themes/elementary/gtk-2.0/gtkrc but it doesn't work, still leaves the gradients in their place. I'm a big fan of the other controls in the theme; the scroll bar, the way it borders gedit and the buttons, and I'd like to keep these features, but I don't like the way it styles its windows. Thanks for any help, as always!

• Ubuntu on a netbook. Wait for 12.10?

  - by Kevin Duke

  My friend has a really slow 2 yr old Toshiba netbook with 1GB of RAM. She is annoyed how slow Windows Starter runs on it so I suggested switching to Ubuntu. Since 12.10 is due in a few days, I'm not sure if we should wait before installing Ubuntu or if we should install it now in order to use Unity 2D. For a low-end device, should we use Unity 2D or use Unity 3D on 12.10 since Unity 2D is no longer present in 12.10? I understand Unity 3D has been greatly improved but is it faster than Unity 2D in the LTS version for a low-spec'd device?

• Menubar hidden in all KDE apps

  - by Francesco Feltrinelli

  I am using Kubuntu 10.10 with Plasma-Netbook on my netbook. Somehow I messed up with window's settings and now the menubar (the one on top of the window, just below the titlebar, which has the File button, Edit, Settings, Help, ...) is hidden from all my KDE applications. Here you can see how the menubar should be correctly displayed: Here you can see how it is actually displayed on my netbook: I don't remember what I did to hide the menubar, I clicked somewhere in the context menu which shows right-clicking on window title, but I cannot find that setting anymore. Can you please help me? Thank you very much.

• How to make whoopsie more silent (log clutter with "online"messages)

  - by Rmano

  I know what whoopsie is from the answers to What is the 'whoopsie' process and how can I remove it? I do not want to stop error reporting, as I think that error reporting is the minimum a user should do to try to help Ubuntu. But since the upgrade to 13.10, whoopsie has grown up quite chatty. I have literally hundreds of messages like that in my logs: SYS: Nov 4 14:40:48 samsung-romano whoopsie[1156]: online SYS: Nov 4 14:41:56 whoopsie[1156]: last message repeated 4 times SYS: Nov 4 14:42:56 whoopsie[1156]: last message repeated 2 times SYS: Nov 4 14:43:56 whoopsie[1156]: last message repeated 2 times SYS: Nov 4 14:44:56 whoopsie[1156]: last message repeated 2 times % zgrep whoopsie /var/log/syslog*gz | wc -l 773 Is there a way to tell whoopsie to be less verbose? (the funny output format is from SLogger, a homemade program to check system log files I wrote ages ago, but this is basically the content of /var/log/syslog file).

• Ubuntu 12.04 - Workspace switcher is shown after switching to another workspace

  - by David Kuridža

  I've just upgraded to Ubuntu 12.04 on HP Envy 14 and found a rather interesting bug. When I switch between workspaces using keyboard shortcuts, for example moving down to Workspace 3 from Workspace 1, workspace switcher is shown (as seen on below screenshot). It stays there until I hit escape key. After debugging, the problem only happens when I change shortcut keys to Super + direction. With default Ctrl + Alt + direction, everything is OK. I've searched but haven't found this problem reported before, I'm also not sure this is called workspace switcher :) Can you please let me know what to search for, are there any logs which might have some related information?
