• How to hide keyboard layout shortcut from Unity top panel?

  - by user67715

  I'm using Ubuntu 12.04 together with X Neural Switcher, which is a program for the automatic switching of the keyboard layout. The switcher goes with a GUI called gXNeur. The GUI places an applet icon to the Unity top panel (the gXNeur had to be whitelisted for the icon to become visible) that help a lot to configure and make urgent changes in the rules that the program uses. But after the icon is whitelisted I'm having two keyboard layout indicators in the panel (one - native, the second one - gXNeur). The native is the one I'd like to hide while gxNeur is more intuitive. Is there a way to do that? Thanks a lot for your help!

• How can I fix the compiz effects lag in unity?

  - by Samir

  I've recently installed ubuntu 11.04, and I actually liked Unity (although many others prefer Gnome), but there seems to be a lag problem. Every time I press the super button to bring out the Dash, or Super+W to show all windows, or any other action that involves some sort of effect, the effect lags a bit, and it could get really annoying. I've seen a fix using CompizConfig Settings Manager, but that doesn't seem to work for me. I've got a NVidia 9800 GT 1 GB video card, a 2 GB Ram, and not sure about the CPU (if you need it, tell me and I'll figure it out). Any help would be appreciated Thanks in advance.

• How to integrate Gmail, Google contacts and Google calendar into Unity without Thunderbird or Evolution?

  - by mpm

  I want to integrate my Google contacts, calender and Gmail to Unity. And I don´t want to use Thunderbird or even worse Evolution. Is there a possibility like in GNOME 3.xx? A lightweight contact / calendar / mail app (maybe one app for contact, one for calendar) would be welcome. Edit: I want to use the calender to sync my appointments with google - e.g. I open my "ubuntu-calender", make a new appointment and it syncs with google calendar. Also return way. The same with contacts. I want a see and edit all my contacts in an app and have them sync with google. Gmail: A notifyer would be enough - just one click on the notifyer and it opens googlemail in chrome. Otherwise an lightweigth email client. Kind regards mpm

• VMWare Unity Mode with Ubunty 12.10

  - by Nick

  This is a very difficult thing to search for, and find an answer to because of the unfortunate choice VMWare and Ubuntu both having something called "Unity". My host operating system is Windows 7 - 64 bit, running VMWare Workstation 9.0.1. I have a virtual machine running Ubuntu 12.10 - 64 bit. When I attempt to put VMWare in "Unity mode", I get the following message: The virtual machine cannot enter Unity mode because: - Unity is not supported on the guest operating system. From the VMWare site, there is nothing listed that says that Ubuntu is not supported for this... and I have installed the latest vmware-tools on the guest operating system. It seems like a lot of people have had this issue, but I haven't seen a good resolution to it yet. Does anyone know how to get Unity mode working with Ubuntu?

• Ubuntu 12.04 Hangs with Software Center open then opening Dash Home

  - by Josea

  I have a Dell D610 - Intel graphics - 1 Gig RAM. I have test the hard drive and RAM and both are fine. When I open Software Center, then Dash home my system locks up. The mouse cursor moves but is unresponsive if I try to right or left click anything. The keyboard is totally unresponsive and I have to hold the power button to power off! I have reinstalled from CD, did all updates but the issue persists. I tried using the track pad only, and I plugged in an external mouse also but no change. Everything else works great ! I am sick of running Vista and have no love for Metro! Thanks for any suggestions, on a scale of 1 to 10 (Newbie - Expert) I am about 3

• How to synchronize a whole Ubuntu?

  - by Avio

  I think that the time is ripe to have my whole Ubuntu synchronized just as my Dropbox folder is. Given that we are always talking about files and directories, what's the difference between my Documents folder and my /usr system directory? Almost none, except for their location. In fact, I think that there is just one big issue that prevents people to have their beloved installations mirrored wherever they go: symlinks. Dropbox, Google Drive, Ubuntu One, Sugarsync, Skydrive, none of these services support symlinking. This means that if I push a symlink in one of the synced folders, locally the symlink is kept as is, but remotely (in the cloud or on the other synced machines) the symlink is resolved to the actual file that was originally pointed to. This completely disrupts Linux installations, thus these services can't be used for this purpose. So the question is. Does anybody knows a way to achieve this? A whole Ubuntu, always synchronized with a remote running copy, but still locally stored on both disks? My best guess is that I could use NFS. But the main difference between Dropbox and NFS is that NFS is a remote filesystem that always forces to remotely access the files, while Dropbox pushes modifcations to local filesystems (and thus would perform better). I've also heard about NFS caching. Does anybody knows if this solution could approximate Dropbox in this sense? P.s. I know that /boot, /dev, /proc, /run, /tmp and device-specific mountpoints in /mnt and /media will have to be left out the sync mechanism. What I'm interested in is the principle. Can this be done with reasonable performance, having reasonable resources (e.g. ~ 1Mbps upload bandwidth and a public IP address)?

• How can I disable as much "flair" as possible in Unity?

  - by UlfR

  I'm running Ubuntu 11.10 from a fresh install on a somewhat aged computer, so I have some speed problems. But since I do want to use the new cool way to work with things that Unity introduces I do not want to fiddle with getting another desktop environment. My idea is to disable as much flair as possible, but there are tonnes of options that I do not understand or have the time to read up on when I launch CompizConfig Settings Manager. Which of these could safely be disabled? Are there other places where performance could be gained by disabling things? So how can I make the whole thing a little more snappy?

• Unity: Is there a way to edit a Skin file?

  - by Roberto

  My project has multiple skins and sometimes we have to deal with skins with many custom styles. Editing them in the editor is difficult, for instance, I cannot delete one style that is not the last one without deleting the ones after it. Would there be a way to edit a file that represents this skin? Could I edit a skin file if I use Text in the Asset Serialization Mode (Unity Pro)? If not, is there something in the Unity Store to help me better edit skins?

• Is Ubuntu Touch a separate distribution or the same one?

  - by Nickolai Leschov

  I would like to install the latest Ubuntu Touch on a 2013 Nexus 7 tablet. Which version should I be looking for: the regular Ubuntu (for ARM platform) or a separate Ubuntu Touch? I understand that after Ubuntu Touch is in frantic development, but I would like to be able to keep track which one is which. I can see the following images: Ubuntu 14.09 RTM, daily-preinstalled Ubuntu Touch 14.10 (Utopic Unicorn) Daily Build Ubuntu 14.10 (Utopic Unicorn) Daily Build, but only i386 and amd64; no ARM. Does it mean that ARM variant has moved to one of the first two links?

• Why does Ubuntu 10.10 show blank screen during startup?

  - by user8372

  When I try to login to Ubuntu 10.10 I get a flickering screen for a second showing - Ubuntu 10.10 ............. and then I get a blank purple coloured screen[Ubuntu's theme colour] which doesn't progress any further Can anybody suggest a remedy to this problem? From whatever questions I searched in various Ubuntu Forums it seems like this problem is likely caused by a missing NVIDIA Display Driver[which is being used in my Sony Vaio Laptop] update in Ubuntu releases If that's the case then how can I update my NVIDIA Display Driver for Ubuntu 10.10 without being able to log into the Ubuntu 10.10?

• Ubuntu web server cluster checks Ubuntu repository for script updates with cron

  - by StuartTheY

  I have a cluster of Ubuntu 12.04 web servers running a lamp stack. All of these servers are connected to a Load Balancer on Amazon Web Services. What I want to be able to do is have a dedicated Ubuntu server that I can update the PHP files on and have the other web servers check with cron to get the updates files from the repository. They don't have to use cron but that was the only thing I could think of, unless there was a way to have the updated repository tell them that it has updated files. And then how to transfer those files. Also if there is a ways for a server to check for updated files when it boots because I am going to be using auto scaling on AWS so when there is an increase in the load and another server gets created I need it to download the updated files from the repository when launched. Not sure how to transfer files from server to server.

• How do I hide my custom Unity panel indicators from another user account on the same machine?

  - by Inkayacu

  I created a second user account on my machine, making it a "standard" user account. When I log into that account, most of the panel indicators I've added in my own administrator user account show up here as well -- but not all of them (e.g., the cpufreq indicator shows up in both accounts, but the multiload indicator does not show up in the second account). I'd like to prevent everything but the default panel indicators from a fresh Ubuntu install showing up in the second user's panel.

• How to configure Unity/Compiz in 12.04 so that Update Manager opens maximized w/screen bigger than 1024×600?

  - by Jani Uusitalo

  In Precise, window auto-maximize is disabled on monitors with a resolution above 1024 × 600 [1]. I have a bigger resolution, but I prefer maximized windows anyway. I want Update Manager to start maximized. What I've tried so far: In Compiz Config Settings Manager, I have Place Windows activated and 'Windows with fixed placement mode' has windows matching the rule "(name=gnome-terminal) | (name=update-manager)" set to 'Maximize'. With this, Gnome Terminal starts maximized, Update Manager does not. In Compiz Config Settings Manager, I have set a Window Rules [2] rule to match "name=update-manager". Irregardless of any rules set or not, activating Window Rules results in not being able to bring out Unity Launcher anymore, Alt+Tab window switching becoming slow or nonfunctional entirely and the screen sporadically freezing completely. Not a viable option apparently. I've installed Maximus [3] and started it. Update Manager ignores it (or vice versa). I've not tried devilspie and would prefer not to. Having to configure something external for this would seem stupidly redundant with (the no-brainer) Maximus and all these Compiz options already available. I just can't seem to make them work.

• How to switch and list windows (possibly of the same application) in Unity?

  - by Bruno

  Is there a way to switch easily between specific windows belonging to the same given application? For example, open Firefox, maximise the window; then, open its History window (History menu - Show all history), maximise it too. Is there an easy way to switch between these two maximised Firefox windows, without necessarily minimising the current window (or other windows in front of the required window)? Similarly, if I open another application alongside, how can I quickly go to the Firefox window of my choice? I have tried Alt+Tab, but when coming back from another application, which of the Firefox windows I end up with seems indeterministic. Under Gnome, I would find the window I'm looking for in the bottom bar. Under OSX, I would right-click on the application's icon and choose the relevant window from the list. Under Windows 7, I would click on the application icon and choose from the smaller windows. Is there something similar that's not activated or not visible by default in Unity? Hovering my mouse until I've found somewhere worth hovering over hasn't been very successful so far. I would prefer a click-based solution, but solutions involving key short-cuts instead are welcome.

• Lost access to the unity interface how to fix? (ubuntu 11.10)

  - by Tal Galili

  o.k, this is embarrassing: I have installed Compiz Config Settings Manager and tried to fix it so that the transition time between changing tabs (using alt+tab) will be short. by accident I un-pressed V from something else, and it asked me about a conflict - I pressed the "x" button to close the window and as a result I stopped seeing the unity interface. That is - I can not see any buttons of the left side. I went to the terminal (ctrl+alt+F1) and ran ccsm As a result I got the following error: $ ccsm /usr/lib/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning: could not open display warnings.warn(str(e), _gtk.Warning) Traceback (most recent call last): File "/usr/bin/ccsm", line 93, in <module> import ccm File "/usr/lib/python2.7/site-packages/ccm/__init__.py", line 1, in <module> from ccm.Conflicts import * File "/usr/lib/python2.7/site-packages/ccm/Conflicts.py", line 26, in <module> from ccm.Constants import * File "/usr/lib/python2.7/site-packages/ccm/Constants.py", line 29, in <module> CurrentScreenNum = gtk.gdk.display_get_default().get_default_screen().get_number() AttributeError: 'NoneType' object has no attribute 'get_default_screen' What should I do next?

• Ubuntu Touch Porting - Audio

  - by user205695

  I'm currenty trying to port Ubuntu Touch to the Galaxy s4 International LTE (GI9505/ jfltexx). I've come to the point where I need to create a UCM directory but I don't know where and how I should call it. By "looking at /usr/share/alsa/ucm/apq8064-tabla-snd-card/" is the local Ubuntu PC directory or a directory on the downloaded CM meant? Same thing for "/proc/asound/cards" which should give a hint about what the directory should be called. 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0xfb200000 irq 51 1 [NVidia ]: HDA-Intel - HDA NVidia HDA NVidia at 0xfb080000 irq 17 I dont think the directory should be called anything like this. Thanks for the help Robin Kertels

• MP3 files cut off in the Ubuntu One Android app

  - by rudefyet

  I noticed today on my phone (Droid X running Android 2.2.1) that when streaming the Ubuntu One app would skip to the next song before the previous one had finished. Looking into it, one of the mp3s downloaded from the server was only 2.5MB instead of 4.2MB as it shows on the server itself via one.ubuntu.com. It's happened with multiple tracks today (I remember it happening once the first time I used the app too but shrugged it off as a glitch). The app itself shows a star on the playlist item indicating the file was downloaded even though it was apparently cut off for some reason, perhaps lack of good cell coverage, or some sort of dropped connection. It seems like the latter may be happening and instead of showing an error or retrying it just stops and shows the download is complete.

  I'm attempting to install Ubuntu Studio 12.04 on my laptop by using VMware Workstation 7.1.5, and I've encountered a problem. The install goes well until the installation of Ubuntu has completed and the installation of VMware Tools starts; after that it just stops. I have waited about an hour and a half and nothing has changed. The installation is on VMware Easy Install, and I am running Windows Vista 32-bit with 3 GB system RAM and 2 GB of RAM on the virtual machine. Any help is greatly appreciated, thank you!

• debootstrap or virt-install Ubuntu Server Maverick fails

  - by poelinca

  Oki so running any kind of variation of debootsrap i get the following error I: Extracting zlib1g... W: Failure trying to run: chroot /lxc/iso/dodo mount -t proc proc /proc debootstrap.log : mount: permission denied if i manualy chroot into the directory then i get promted with: id: cannot find name for group ID 0 I have no name!@...# i tryed addgroup but it's not installed , apt-get/aptitude : command not found , so i can't do anything with it . I've tryed ubuntu-vm-builder but since it's calling debootstrap i get the same error . Played with it for a few days and then i stoped and gaved virt-install a try , everithing works till i get to the console to finish the install witch shows only : Escape character is ^] and nothing more , no matter what i type . So basicly what i'm trying to do is build a usable chroot system so i can use it with lxc or libvirt . What are my options to get containers/virtualisation up and running ? I've read somewhere that i can use openvz templates with lxc or libvirt ? but how ? Let me know if you need aditional info ( p.s. doing all this on a dedicated server so i can't access it by hand , only ssh , plus on my local pc running ubuntu desktop maverick everithing works ) . EDIT Getting closer , i managed to understand how to use an openvz template with lxc , now the problem comes with the network bridge lxc-start: invalid interface name: br0 # Use same bridge device used in your controlling host setup lxc-start: failed to process 'lxc.network.link = br0 # Use same bridge device used in your controlling host setup ' lxc-start: failed to read configuration file i followed the exact steps to create a bridge and lxc conf looks like: lxc.network.type = veth lxc.network.flags = up lxc.network.link = br0 # Use same bridge device used in your controlling host setup lxc.network.hwaddr = {a1:b2:c3:d4:e5:f6} # As appropiate (line only needed if you wish to dhcp later) lxc.network.ipv4 = {10.0.0.100} # (Use 0.0.0.0 if you wish to dhcp later) lxc.network.name = eth0 # could likely be whatever you want Since it's not working i know smth is wrong so could somebody guyde me ? EDIT , looks like the base install was using an custom kernel ( bzImage-2.6.34.6-xxxx-grs-ipv6-65 ) for witch you i didn't found the headers , i did a update-grub after i installed a new kernel , edited menu.lst and no it's using 2.6.35-23-server and now debootstrap is working just fine same as ubuntu-vm-builder .

• 12.04 Ubuntu studio PREEMPT_RT kernel options

  - by Nate Iverson

  My audio processing needs require a preempt_rt kernel. I roughly followed the guide: https://wiki.ubuntu.com/KernelTeam/GitKernelBuild with a little help from: https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO Currently I am using the 3.4 branch (which is the most recent at the time of this post): http://www.kernel.org/pub/linux/kernel/projects/rt/ I think I have a reasonable kernel config ( for my machine at least ). Multiple trials confirm I need the option: CONFIG_PREEMPT_RT_FULL=y I have the following questions: Is anyone maintaining a recent CONFIG_PREEMPT_RT_FULL kernel in a ppa? Is there any interest in providing a CONFIG_PREEMPT_RT_FULL in the official ubuntu-studio distribution? Does anyone have recent config pointers for a CONFIG_PREEMPT_RT_FULL kernel?

• Remote install of Ubuntu Server

  - by David Walker

  Hi all, I have a machine located 500 miles away that's running Ubuntu 8.04. I figure it's just about time that I upgrade to the latest LTS. However, there's a software raid (md_raid) in there, and I'm afraid that just a dist-upgrade when I switch over the sources.list will end with catastrophic failure. Like a panic on boot that the raid'd disk can't be read, or something else. First, hoping that's not the case, however, if it ends up happening I'm wondering if there's a means of having someone drop in a Ubuntu 10.04 server install disk, and flip on ssh, and some means for me to hop on and re-run the installer remotely. Is this feasible? If so, what would one need to do aside run apt-get install ssh on the target machine? I do have friends who can be in front of the target machine to initiate the process, just not execute it out.

• Laptop not syncing with Ubuntu One

  - by Lolwhites

  I have a desktop running Maverick, and a laptop running Lucid. Both are supposed to be linked to my Ubuntu One account. The desktop syncs fine, but when I started the laptop for the first time in a couple of months, it wouldn't sync any more. The Ubuntu One Preferences window either reports "Synchronisation complete" even though no recent files have been downloaded nor have any test files created in the relevant synced folder been uploaded, or it says "Synchronisation in progress", which does not appear to be happening as it stays like this for ages and the lights on my router suggest no traffic is going through. Have repeatedly tried disconnecting and reconnecting, and removing the device from the account then reattaching it, all to no avail.
