• Ubuntu 12.10 64bit fresh install, wireless issue!

  - by Dave

  Just installed a fresh Ubuntu 12.10 64bit on my laptop, run the update manager, restarted and suddenly I can't use my wifi anymore. Ubuntu software center installed automatically the wifi additional driver as you can see in my screenshot. If I mark the option "Do not use the device" and apply changes, restarting Ubuntu my wifi is back and I can use it. If I run iwconfig my terminal is showing this Now if I use Ubuntu for more than 20 minutes surfing the web my wifi it keeps to be connected but I don't receive any signal from it. Any page I try to open it simply don't open (just waiting icon). If I disconnect my wifi and connect it again, same issue, it doesn't work. The only way to make it work again is to restart Ubuntu. And the same story it happens again after aprox. 20, 30 minutes. WIFI device details: 03:00.0 Network controller [0280]: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller [14e4:4727] (rev 01) Thanks, Dave

• Why can't I upgrade my kernel via the terminal?

  - by Alvar

  If I type sudo apt-get update && sudo apt-get upgrade I can only see that the kernel packages are kept back, and not installed. As the screenshot shows. If I then start the update manager I can install the kernel, with no problems at all. As the second screenshot shows. Why is this? The kernel is a new package and not an upgrade of an old one, this is why you can't use the command upgrade that upgrades packages. You need to use the command dist-upgrade to install new packages.

• Can I force window to open on top of other windows when opened by keyboard shortcut?

  - by Rasmus

  I use SpaceFM as my primary file manager on Ubuntu. I typically open folder directly by keyboard shortcuts, so, e.g. Ctrl+Super+W opens my Work folder. Specifically, I use execute the command spacefm -w /home/rasmus/Work/ by the above shortcut, with the -w ensuring that SpaceFM opens a new window. However, this new window is not always open on top of the last active window on the workspace. This is rather annoying, as it means I sometimes have to "dig" for the newly opened window. So, my question is: Is there something additional I can add to the executed command that will ensure that the fresh window is opened on top? Alternative solutions to the same effect are welcome.

• how to remove update repo that always fails

  - by David M. Karr

  A week or so ago I tried to add a new package repo that supposedly had a package I wanted. Unfortunately, the information about it was out of date, and I found that it fails to connect to it each time. I'd like to just remove the new repo, but I'm not sure how to do that. For context, when I update, I get this: W:Failed to fetch http://ppa.launchpad.net/geod/ppa-geod/ubuntu/dists/precise/main/source/Sources 404 Not Found [IP: 135.214.42.30 8080] , W:Failed to fetch http://ppa.launchpad.net/geod/ppa-geod/ubuntu/dists/precise/main/binary-amd64/Packages 404 Not Found [IP: 135.214.42.30 8080] , W:Failed to fetch http://ppa.launchpad.net/geod/ppa-geod/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found [IP: 135.214.42.30 8080] , E:Some index files failed to download. They have been ignored, or old ones used instead.

• Networkmanager in systray gone and sound not working after update 13.10

  - by rubo77

  After upgrading my Xubuntu 13.04 to 13.10 I have no sound. I still have sound if I start VLC with sudo mpg123 test.mp3 So it seemd there is a right problem EDIT after adding myself to the group audio with adduser myself audio I could play sounds again from the desktop with VLC But one problem remaining: The systray, usually looking like this: is not working anymore. No audio-settings and no network-manager in the taskbar in XFCE: there is just one small box with nothing in it. When I install stalonetray, There I see the status of wicd and all the other statuses, so the systray seems to be broken.

• When clicking below window title bar in KDE, window dragging is initiated. Can I change this behavior?

  - by hdpq

  this one is regarding KDE in Ubuntu 12.04. The thing is that whenever I click below the window title bar in KDE, the window manager always assumes I want to drag the window, not just activate it. Clicking the title bar activates the window without dragging it just fine, however I sometimes find it hard to click because it's rather narrow :) Is there any way to change this behavior (besides the obvious "make your title bar larger" thing)? I also assume this is happening to Gtk applications only (Firefox, Thunderbird, Synaptic), as I have tried it with several KDE apps (KWrite, KTorrent, Gwenview, Konsole) and noticed no such behavior. Thanks in advance!

• Jquery website is not opening in UBUNTU but in XP, Everything is fine

  - by Raman Sethi

  I know it is weird, But I just discovered this, jquery.com is not opening in my ubuntu firefox or other KDE browser and hence many sites that copy codes from code.jquery.com also hanged. Is there any solution to this problem. I have found the problem It is actually with the DNS servers I am using, Google DNS, 8.8.8.8 and 8.8.4.4, whenever I use these DNS in ubuntu my system stop responding to some sites, actually they are connected nicely, but the request end up in waiting.. I dont understand why...??? I checked my DNS with cat /etc/resolv.conf Even after using Google DNS, it is showing DNS servers I received automatically after connecting to the service provider. I am connecting using Network Manager, not using DNS I provided but using the default one. Any Solution??

• How do I use apt-get to update to the latest kernel?

  - by Bucic

  My current kernel is 3.2.0-26 (my main computer) while on another of my Ubuntu computers, with which I didn't fiddle with unofficial updates, it's 3.2.0-30. Yet the Update manager on my main computer doesn't show available kernel updates. It shows other updates though. I suspect is due to the fact that in the past I installed multiple mainline kernel versions (not recommended versions), up to 3.5* series. What I'm after: Either: Fix automatic kernel updates. Or: Learn about a way to check for the latest official ubuntu kernel version and get it manually (I know how to install kernels from debs) What I have already tried: Uninstalled unused kernels including "the generic one without a number" as per http://askubuntu.com/a/103875/29347 and then also https://ubuntugenius.wordpress.com/2011/01/08/ubuntu-cleanup-how-to-remove-all-unused-linux-kernel-headers-images-and-modules/

• Program To Cascade/Tile Windows

  - by Richard

  I have perhaps ten or fifteen windows open. I'd like a program which automatically resizes all the windows and arranges them in columns and rows across the screen (a grid formation), automatically figuring out the largest size for the windows so that they still fit. This isn't an "Expose" type program - I want the windows to stay resized. I am using OpenBox to do my window management and am otherwise happy with it, I don't want to find a whole new window manager just to solve this problem. The program Tile is almost perfect, but it doesn't know how to lay the windows out in a grid formation. Any thoughts? Thanks!

• Internet connection randomly drops out

  - by Dr_Bunsen

  Since a week or 2, I have this random network failures. No error pops up, the system says it's still connected to the internet(wifi and wired). The problem is, I can't connect to anything, even a ping google.com gives no feedback. And after many network-manager resets it will work again, for just a minute, and drop out again. I noticed that the /etc/resolv.conf contains this line: nameserver 127.0.0.1 I left out the "Do not edit" stuff, and after it worked for a second, this line is added: search lan When I change the nameserver to 8.8.8.8, I am still able to connect to anywhere. Does anyone got a clue what is happening here? I will provide any information asked. Thanks in advance p.s. I run Ubuntu 13.04 since lastnight(24-06-2013)

• No graphics after installing AMD Catalyst 12.4 and installing the recommended updates afterwards

  - by Innonic

  Some days ago, I installed Ubuntu 12.04. Since I wanted to use dualview using an external display I installed the propriatary AMD Catalyst 12.4. The graphics are fine, but if I run the updates found by the updates manager, Ubuntu won't be able to start with graphics after reboot. I installed Ubuntu 3 times until I realized what the problem was. So now I got the basic installation with Catalyst running but I can't update the system. Is there any solution to this? Or can I somehow identify which update causes this? My System is a Lenovo y560 Ideapad (Intel Core i7, 8GB RAM, with AMD Radeon HD 6570M/5700 Series. Thank you in advance

• Cisco AnyConnect VPN Client broke my internet

  - by user137864

  I was using the AnyConnect client when it froze and I had to do a hard reboot of my computer. Now I can't connect to the internet at all, with or without VPN. The Network Connections manager seems to think I have a wired and wireless connection without a problem, but I can't go online. I have tried using /etc/init.d/networking restart and it even says it is "ok" with no luck. I am guessing I need to clear some settings somewhere and restart a service, but I am not sure what. Thanks!

• how to find available wireless networks

  - by Quinn

  I'm using an HP Pavilion dv6000 I've looked at other answers similar to this question how ever when I look at my network symbol it doesn't say anything that the answer below says "Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right. Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears." it how says 'Enable Networking' my wi-fi switch is on and I've tried using terminal to kill the applet as another answer suggests trying. Does anyone have any other ideas that might help? Just in case anybodies curious as to how I'm posting this I'm on my other ubuntu laptop that's running an older version.

• How to merge multiple internet connections into one

  - by Luis Alvarado

  My PC has 2 wired cards. Both gigalan. It also has 2 wireless cards. One broadcom with proprietary drivers and ralink with open software (which works much better than broadcom). My cellphone can share its connection wirelessly to my PC. But I also have a wired connection. So I have multiple connections that I can use to have internet. How can I merge 2 or more connections together and balance them to enjoy one unified internet experience that it is the sum of all internet connections connected to it. For example if I have an internet connection that offers 1024KB/Sec and another that offers 512KB/Sec and one small one that offers 128KB/Sec, after load balancing and merging all connections, I could download at a speed of 1664KB/Sec using all 3 internet connections as one for example. This question has always intrigued me.

• Fixing IP Renewal After Laptop Suspend

  - by Cerin

  I have a laptop running Ubuntu 10.04, and I've noticed that with some wifi networks, but not all, I'm unable to reconnect after coming out of suspension. I've tried both Network Manager and Wicd management daemons, and both get through validation, but get hung up on "Acquiring IP address...". The only solution I've found is to reboot the machine, after which it acquires an IP address very quickly. What's the underlying issue here? What would be a more efficient way to resolve the problem? EDIT: I've noticed that if I open Wicd and manually press "Connect", it fails to acquire an IP. However, if I do nothing and let it automatically try and connect, it acquires an IP and connects just fine...

• How to set Ubuntu as wireless accespoint in the GUI way?

  - by Agmenor

  My aim is to make my Ubuntu machine be a wireless accesspoint using wifi. Of course I found two AskUbuntu questions already treating that; this one and that one. Nevertheless, as far as I am concerned I would like to set up such a network in the Graphical User Interface (GUI) way. Please avoid solutions with the command line. So a solution suggesting to use Network Manager would be really welcomed. Please name and describe very precisely each step, so I can easily find the equivalent in my own language. Thank you for your answers!

• Window colors/shades/decoarations/whatever per instance

  - by user35186

  Sometimes I open several instances of one program at the same time and have to switch between them every few seconds and get totally confused as to which is which (they all display similar information, except few bits). I'd like to have each one of them color-coded, different shades, window border, etc or have anything visual to make them differ from one another to ease the confusion. Ideally this would happen automatically when I launch a new instance. I guess this belongs to the window manager so mine is xfce. In one of the window managers I used to use a huge label was displayed each time I switched between workspaces, something like that (with window title or simple number) would do as well. Any clues?

• mobile broadband quick connect..how to?

  - by Ubuntuser

  Hello all, I have a Reliance broadband + mobile broadband connection. It connects fine, but the only problem is it takes more than 2 -3 mins to get the connection started. If I plug in the USB datacard, the network manager applet dothes not show up the mobile broadband connection immediately. It takes a good 2-3 mins to detect the connection before I can select Reliance connection from the dropdown list. Is there any way of getting a shortcut of that connection on the desktop or on the panel? Thanks, Sayantan

• How to set up an ethernet and wireless network using /etc/network/interfaces?

  - by den-javamaniac

  Hi. Currently I have ethernet and wireless networks configured through a network manager (further NM) but it seems to be a bit buggy (I need a different MAC for ether which is never applied if using NM), so I would like to move all the network configs to interfaces file. I know (or can google for) configuration code, but I'm not sure how NM works and it looks like it overrides interface config. Please advice, how I can handle this issue. NOTE: I also would like to be able to locate and connect to various wireless networks but not sure how to do it.

• Is it possible to auto-mount sshfs

  - by Mark D

  Is it possible to auto-mount a remote FS using sshfs upon instantiating a proper VPN connection? Allow me to explain the scenario, I'm working remotely, to do that it helps if I can mount my home dir from a server in the office. To do that I need to vpn in. So within network manager I select the relevant VPN and connect. It connects but now I have to drop to the command line and mount my home dir on several machines. If I forget to do one machine my local dev environment isn't as efficient. I suppose I could write a quick bash script to do this but I'd rather get it running automatically when I connect.

• Realtek 8188ce stops working after 2minutes

  I am using ubuntu 12.10 on an hp dm4-2191us via wubi with the Realtek 8188ce wifi adapter. Everything works very well with the exception of the wifi. I have used wicd and it didn't worked at all so i went back to Network Manager with variable success. It works for 30 min - 2 min before i have to reconnect to get it to work again. I would really like to use Ubuntu (it is a better platform in my opinion) but no wifi could really be a deal breaker.
