  • How do I make mailto: links open gmail in Ubuntu?

    - by Matthew
    I've tried using this How-To Geek guide, but it doesn't work. Running the script from the terminal works (although I had to change its permissions first), but clicking on a mailto: link does nothing. Note: I am using the Chromium Daily Builds for my browser. I would mailto: links in all applications to point to gmail, not just the ones that I click on in my browser.

  • How to vertically split widescreen into two virtual workspaces on ubuntu/gnome?

    - by David
    My new laptop has a big 16:9 screen, and I'm finding it hard to fully utilize it during the 95% of the time that I'm not watching HD movies on it. I'd like to set it up as a kind of virtual dual screen by splitting the physical screen into two workspaces. I know I could arrange my windows manually, but I'd like to be able to maximize a window and have it only consume half the monitor, and have its pop up dialogs centered on its half-screen, that sort of thing. Is there some kind of plug in available to do this? Thanks in advance for any pointers.

  • Lucid Lynx login issue

    - by Bart Silverstrim
    Recently upgraded from Karmic to Lynx. Upgrade seemed to go well, no noticeable issues. I logged in, and my window manager wasn't starting. An application would appear, but sans control buttons and border, so figured the windows manager needed to be given a swift kick. Opened a web browser and a quick google had me run "metacity --replace &" and everything popped up. I re-ran the Compiz configuration tool to enable my rotating desktop cube to the way I liked it, and had to reconfigure my desktop switcher to the right number of desktops (although the first time I ran it, it crashed on the panel and reloaded...odd, but once it relaunched it seemed fine.) Today I installed updates, rebooted and logged in for the second time since my upgrade. Again, the window manager was dead, and my compiz settings were gone, and the workspaces were set back to four (and when I clicked on the preferences to change them, it crashed on the panel and reloaded again). Resetting everything made things look somewhat normal again. I'm guessing it'll work until I reboot again. Googling around isn't turning up similar complaints about Lucid Lynx and the window manager. Before I go deleting preference files, anyone else know of this kind of issue and what could be done about it? Or should I start taking the stab in the dark approach of deleting preference files hoping one of them is corrupt or has something unsupported in it that's throwing LL for a loop?

  • How to get the Three.js import/export scripts into Blender on Ubuntu?

    - by Bane
    I have been working with 3D primitives in Three.js, but now I want to import some models. I plan on using Blender, which I have just downloaded with: sudo apt-get install blender However, I was instructed to put the import/export scripts in the .blender/2.62/scripts/addons folder, but it does not exist! .blender/2.62 does exist, but it only has a config folder. The next thing I did is manually changed the script search path in Blender's preferences from // to my homefolder/scripts, which contained the required io_mesh_threejs folder (which, in turn had the .py scripts inside). I saved the changes, restarted Blender, but still nothing: in the menu there is no mention of Three.js at all! What do I do? It would be great if I knew the installation path for Blender, because maybe I could put those scripts there manually. Where should it be installed? EDIT: these are the scripts I'm talking about, along with the instructions: https://github.com/mrdoob/three.js/tree/master/utils/exporters/blender.

  • Possible boot conflict?

    - by Evan Kroske
    I was installing Ubuntu on a computer on which Windows XP was already installed. The computer has multiple hard drive bays, so I decided to remove the XP HDD and install Ubuntu on a blank HDD when it was the only HDD in the system. Unfortunately, if I now try to boot Ubuntu with the Windows XP drive in the second slot, nothing will boot. However, if Windows XP is in the first slot, it will boot fine. Can anybody explain why this happens? When I was checking out the BIOS to see if something was messed up, I discovered that when Ubuntu is in the first slot, the BIOS doesn't recognize any HDDs. However, if XP is in the first slot, the BIOS recognizes both drives. Any hypotheses about why this happens? Edit: Here's the setup. I have an old server with seven SCSI HDD slots. I have five identical 68 Gb SCSI drives, but I can keep only two plugged in. XP is still installed on the first drive, but I reinstalled Ubuntu on the second drive and had Grub overwrite the XP bootloader on the first drive. Now, the setup works fine, and I can use Grub to load either XP or Ubuntu. However, if I plug in another identical blank HDD in the third slot, the computer recognizes only the XP drive and doesn't boot. Grub starts to load, then gives me a "disk not found" error. Running ls from the grub rescue prompt only shows one drive with two partitions. I guess this is a BIOS problem, but I'd still like to know what triggers it. What about a blank drive could cause the BIOS to freak out?

  • How can I reset the permissions of /bin /boot /etc and /dev to orignal owner, Ubuntu?

    - by Camsoft
    I accidentally changed the ownership of the /bin, /boot, /etc and /dev recursively to nobody:nogroup using chown when I misplaced a forward slash! How can I resort the original file ownerships? I've managed to get them all to root:root but I'm not sure if all the files should be owned by root and if this will break something? Is they are option to fix file permissions like there is in OS X? Help!

  • Can't change permission/ownership/group of external hard drive on Ubuntu.

    - by MikeN
    I have an external hard drive connected to my Linux box. I wanted to setup a web server to access files on it, but the permission on all files and directories on the drive are "rwx" for the owner which is my local login, and the group is the "root" group. I need the files readable by the apache user, I was trying to set all files to be "chmod a+rwx -R *", but this doesn't do anything (gives no errros, just has no effect.) I tried chaning the group using "chgrp" to my user group, but that won't work either, it gives me errors that I lack permission even when I run all those commands as sudo! What's up with this hard drive??? "sudo chmod a+rwx *" should work on anything, right?

  • Ubuntu Pound Reverse Proxy Load Balancing Based off active server load?

    - by Andrew
    I have Pound installed on a loadbalancer. It seems to work okay, except that it randomly assigns the backend server to forward the request to. I've put 1 backend machine under so much load that it went into using swap, and I can't even ssh into it to test this scenareo. I would like the loadbalancer to realize that the machine is overloaded, and send it to a different backend machine. However it doesn't. I've read the man page and it seems like the directive "DynScale 1" is what would monitor this, but it still redirects to the overloaded server. I've also put in "HAport 22" to the backend figuring since I can't ssh in, neither could the loadbalancer and it would consider the backend server dead until it gets rid of the load and responds, but that didn't help either. If anyone could help with this, I'd appreciate it. My current config is below. ###################################################################### ## global options: User "www-data" Group "www-data" #RootJail "/chroot/pound" ## Logging: (goes to syslog by default) ## 0 no logging ## 1 normal ## 2 extended ## 3 Apache-style (common log format) LogLevel 3 ## check backend every X secs: Alive 5 DynScale 1 Client 1200 TimeOut 1500 # poundctl control socket Control "/var/run/pound/poundctl.socket" ###################################################################### ## listen, redirect and ... to: ## redirect all requests on port 80 to SSL ListenHTTP Address 192.168.1.XX Port 80 Service Redirect "https://xxx.com/" End End ListenHTTPS Address 192.168.1.XX Port 443 Cert "/files/www.xxx.com.pem" Service BackEnd Address 192.168.1.1 Port 80 HAport 22 End BackEnd Address 192.168.1.2 Port 80 HAport 22 End End End

  • Ubuntu 9.10 Karmic, nVidea Quadro NVS 280 PCi, Eizo S1921 Dual Screen (Twin View) Slow Window Draws

    - by Spasm
    I have been following this Tutorial to get dual monitors working on my box http://www.dwasifar.com/?p=862&cpage=1#comment-5727 It works! However, when ever I move a window, the redraw of that window takes 3-8 seconds. Even moving the window takes the same amount of time Is this being done in software rather than the nVidea hardware? The windows themselves do not respond. I have seen a few old threads but no relevant fixes - If anyone could suggest a fix I would very much appreciate it. Thanks in advance

  • How does allmyapps.com work on Ubuntu and Windows?

    - by zengr
    The question describes everything, how does allmyapps work? With a single click (like iPhone app store), you click on install and my system asks me "DO you want to install?" In contrast to regular installation, we 1st download the .exe or .deb and install it. So, how is it possible via web? I think, I am missing out on something very basic, but can some one please explain.

  • Shouldn't emesene themes change the emesene indicator icon?

    - by D Connors
    As it stands right now, I can't get the emesene icon in the indicator applet (or notification area, or whatever it's named) to change. No matter what icon theme I choose, even installing new themes, the icon is always the default one. Is that a standard behavior, or am I getting a bug? I'm running the latest version of emesene from their ppa (1.6-dev), on Lucid Lynx.

  • Ubuntu - Automatically mount external drives to /media/LABEL on boot without a user logged in?

    - by endolith
    This question is similar, but kind of the opposite of what I want. I want external USB drives to be mounted automatically at boot, without anyone logged in, to locations like /media/<label>. I don't want to have to enter all the data into fstab, partially because it's tedious and annoying, but mostly because I can't predict what I'll be plugging into it or how the partitions will change in the future. I want the drives to be accessible to things like MPD, and available when I log in with SSH. gnome-mount seems to only mount things when you are locally logged into a Gnome graphical session.

  • How does it hurt to use Linux (Ubuntu) as a guest OS for all my tasks?

    - by sauparna
    I have a machine running Windows, where the disk has two partitions C (50 GB) and D (250GB). I do research in Information Retrieval and need to work with a large corpus (more than 50 GB) and in Linux. So if I want to install Linux on the existing system, keeping the Windows installation intact, will it be fine to run it in a virtual box? (say, QEMU, VMWare, etc.) An alternative is using Wubi. In that case the Linux installation has to be on drive C. Then, if I keep a small Linux installation (say 5GB) on C, and my corpus on D (mounted in Linux), how will it affect the performance of my programs which would be accessing the mounted Windows drive D. Is it feasible to use Linux this way? Which of the above is better if at all they are a way out? Note : Since my post in July 2010, I have been using and have tried several ways of maintaining a disk-image that I can mount in Linux. I had a 100GB qcow2 disk and a 100GB raw disk, both formatted to an EXT3 file system. I was mounting and connecting to the qcow2 disk using qemu-nbd. The problem was that every now and then, the connection to the disk would get lost and the running programs would throw disk I/O errors. The raw disk would mount and work fine as a loop mounted device, but when writing data to it, the mount.ntfs program would hog the CPU and the process would take an enormous amount of time. I was in fact running make on a piece of software located on this raw disk, and after a point of time make was waiting while mount.ntfs would show 100% CPU usage.

  • How do I remap ctrl-j to ctrl-c on ubuntu?

    I'm trying to remap a bunch of my keys and I'm running into trouble. I'm currently trying to use xmodmap but failing. Maybe there is a better way? Can someone explain how I can best remap ctrl-j on the keyboard to produce ctrl-c? It's not as easy as just making j=c. I want this happen only when I'm holding down ctrl.

  • Anyone know how to get dual screens working on a Dell E6410 laptop with Ubuntu 10.04 64 bit?

    - by Curtis
    I've installed the drivers from nVidia. When I go into the NVIDIA X Server Settings application, in the X Server Display Configuration setcion, and click the "Configure" button, "TwinView" is disabled. Also, clicking "Detect Displays" doesn't pick up my monitor (which is connected through a port replicator - keyboard and mouse in that port replicator work fine). Has anyone else seen this? Is this just a limitation of the current nvidia linux drivers?
