• Why is Ubuntu offline (except torrents) while Windows is online?

  - by Fahim al Islam

  I am using a static wired connection. Everything was perfect. But suddenly from few hours back I can't access any website. Dropbox, Ubuntu One also can't connect. Ping request is also unsuccessful, but I can download through torrent. I am not trying torrent download and browsing at the same time. So, I think it's not an issue about torrent using all the bandwidth. One important point is that this connection works perfectly on Windows on this same PC (My PC is dual-boot). I have tried the way what izx has suggested (using "sudo sh -c 'echo nameserver 8.8.8.8 /etc/resolv.conf'"), but I'm facing the same problem again. Now I can't even ping 8.8.8.8 and google.com. Though I can ping 74.125.228.2 (which is Google IP address) I can't understand what's happening and why this is happening. I'm new in this website many rules and regulations is unknown to me. So, please don't be bothered for my mistakes. Looking forward for help from anyone. Thanks to all.

• Git push origin master

  - by user306472

  I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

• Good development themes/environments for Gnome/kde/whatever?

  - by EvanAlm

  I've searched forever for good themes or customized versions of any type of x-server that is designed for development in terms of web productions/programming for all kind of stuffs. Features such as simplified workspace overviews, good tabbing support etc. For multimedia "UbuntuStudio" exists, and something like that but for programming instead. I know that it's possible to customize it by myself but I don't have the skills to make it all happen. Another reason why it's hard for me to customize it is that I simply do not know everything that would make it good for me. I've looked into gnome-shell and it has (according to me) superb workspace overview functions, but lacks in other spaces instead. Any help in finding a good solution for me in this case is appreciated. If some of you also have had this problem and found a solution that works for you, please tell me how you did :) Would love to solve this for once!

• What does the "build-essential" & "build-dep" Terminal commands mean & do in Linux based operating s

  - by Adam Siddhi

  Hi. I am researching how to install Ruby 1.9.1 in Xubuntu 10.04 and I came across the command build-essential and build-dep multiple times. Sometimes it is followed by packages and sometimes it is both preceded and post-ceded by packages. The 2 examples I am looking at are: sudo apt-get install build-essential zlib1g zlib1g-dev zlibc libruby1.9 libxml2 libxml2-dev libxslt-dev sudo apt-get build-dep ruby1.9 and sudo apt-get install ruby irb ri rdoc ruby1.8-dev libzlib-ruby libyaml-ruby libreadline-ruby libncurses-ruby libcurses-ruby libruby libruby-extras libfcgi-ruby1.8 build-essential libopenssl-ruby libdbm-ruby libdbi-ruby libdbd-sqlite3-ruby sqlite3 libsqlite3-dev libsqlite3-ruby libxml-ruby libxml2-dev Thanks :adam

  Can anyone recommend a safe solution to recursively replace spaces with underscores in file and directory names starting from a given root directory? For example, $ tree . |-- a dir | `-- file with spaces.txt `-- b dir |-- another file with spaces.txt `-- yet another file with spaces.pdf becomes $ tree . |-- a_dir | `-- file_with_spaces.txt `-- b_dir |-- another_file_with_spaces.txt `-- yet_another_file_with_spaces.pdf

• How do I fix the HDMI/DVI display output with Intel HD 4000 Graphics in 12.04?

  - by YumYumYum

  I have an Alienware Dell PC with Intel HD 4000 Graphics (Ivy Bridge) as verified by the output of lspci | grep VGA posted below. 00:02.0 VGA compatible controller: Intel Corporation Ivy Bridge Graphics Controller (rev 09) The PC only has HDMI and DVI display outputs and using the HDMI output I am only being offered abnormal resolutions. As you can see below it does not even list HDMI1 or DVI1 but just only a fallback. $ export DISPLAY=:0.0 && xrandr xrandr: Failed to get size of gamma for output default Screen 0: minimum 640 x 480, current 1360 x 768, maximum 1360 x 768 default connected 1360x768+0+0 0mm x 0mm 1360x768 0.0* 1024x768 0.0 800x600 0.0 640x480 0.0 How can I fix this?

• How do I force Wubi to install a 32-bit version?

  - by marx

  I'm using Windows 8 (32bit) customer preview and installing WUBI Ubuntu 12,04.1. I down loaded 32 bit installer from ubuntu dot com, The wubi installer says AMD 64 xt. I had a previous 12,04 install and in the terminal typed in uname -a, it say's 64 bit. I also opened detail from the system and it read 64 bit system. My question is: how to ensure that a windows/wubi/ubuntu/installer is 32 bit or 64 bit BEFORE making a commitment to install from the wrong wubi install? After posting this I did another wubi installation. Signed into ubuntu, opened system settings, open Details: OS Type 64 Bit. Why is it doing this? I have a 32 Bit machine: Toshiba Satellite A-215 S5818 (previous Windows Vista)<--wiped clean. from an earlier installation of Ubuntu 10.10 which worked, in feb 2012 i installed Win8 Customer Preview Release (32Bit) which took over the BOOT order and 140 GB Hard Disk. I am trying patiently to install WUBI 32 BIT Ubuntu 12.04 Install, it keeps returning 64 BIT install.. Why?? I should also mention that i was successful in a dual boot install ubuntu 10.04/win8 32 bit install and upgraded to 12.04 which is fine for now, but i want a win8/wubi/ubuntu12.04 32 bit working not 64 bit breaking what i have. thank you.

• Wireless drops on HP ENVY dv6 with RT3290 wireless, worked without problem prior to upgrading to Ubuntu 13.10, can it be fixed?

  - by Tim

  I have a HP ENVY dv6 Notebook PC with an AMD A10 quad core and RT3290 wireless. Since I upgraded from Ubuntu 13.04 to 13.10, the wireless connects, but then drops after a few minutes or longer, whether or not I am running openconnect to get through a VPN.

• Question about Linux Device Drivers.

  - by smwikipedia

  I have just installed the Xubuntu. My box runs quite slower than before when installed with a Win7. I am wondering if I am missing some device drivers. I can use gnome-device-manager to list my devices. In the device list view, I saw several blue question mark on the left side of devices. Based on my windows experience, the question mark should indicate the device is not properly configured. Is it the same with gnome-device-manager? And most importantly, how could I know for sure whether or not the corresponding device drivers have been installed? Many thanks.

• Problem in accessing Windows shared folder on Ubuntu using terminal

  - by vikramtheone

  Hi Guys, Description I have 2 systems with me, one running on Windows(Host) and one on Ubuntu, both on a LAN. On the Windows(Host) I develop software intended for the Linux system and because the Linux system has little external memory, my idea to overcome this is by making the project folder on the Host side a Shared Folder with full access and access it on Ubuntu over the network. To achieve this, I have installed Samba on Ubuntu, when I go to Places -> Network I can see the shared project folder and I simply mount it. A link appears on the desktop. Next, using Nautilus I open the link and I can access the contents of the shared folder. Problem Even though I mount the shared project folder, I don't see it appearing in the /media or the /mnt folder, as a result of this I don't know what path to use to access this folder, from the terminal. For example: When, I mounted my USB stick, as expected, a link for the device appears on the Desktop and I also see a folder in the media folder. So, similarly, a mounted shared folder should have appeared on the /mnt folder, too. Can anyone suggest what I should do now? There are many posts around, but no solid solution for this problem. Help!!! :) Vikram

• Ubuntu won't suspend anymore, but it did upon install.

  - by Bruce Connor

  I fresh installed Ubuntu 10.10 back when it came out, and my laptop was suspending fine. All of a sudden, I can't get my laptop to suspend anymore. It's an HP Pavilion dv2-1110, but I don't think it's a hardware issue, here's why: It suspended fine upon first install. I haven't installed any new kernels since then, but I have installed tons of packages, so it's probably a package. The suspend and hibernate options disappeared from the shutdown menu. If I press my keyboard's suspend button (or if I close the lid) I get the following message: If I try the command pmi action suspend, I get the error message: Error org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.Hal was not provided by any .service files. If I try the command echo -n mem > sudo /sys/power/state I get absolutely no output and no visible effect. What might be causing this behavior? I thought a list of installed packages might be useful, but it's huge and I don't know how to post it here in collapse/expand mode or something. EDIT:Just in case someone asks, none of the installed packages are kdm or anything like that (which would justify the lack of options in gnome's shutdown menu).

• How do I force apt-get to install a package that will not install due to a bug introduced by Ubuntu 11.10?

  - by Hemm

  Ubuntu 11.10 separated out python-profiler from the Python standard library due to licensing philosophies. (According to what I could Google, correct me if I'm wrong.) This is an active bug since October for 11.10. I have Python 2.7.2 installed, so the dependency errors are wrong. 'apt-get check' does not resolve the problem. What is the best way to resolve to this? Thank you. sudo apt-get install python-profiler 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: python-profiler : Depends: python (>= 2.5) but it is not going to be installed Depends: python (< 2.8) but it is not going to be installed E: Unable to correct problems, you have held broken packages.

• Botting from a stick drive

  - by Zap

  Am trying to boot from a usb stick. Have carefully followed the instructions at the following link and successfully downloaded and installed version Ubuntu 12.04 desk top: http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows I used the Universal-USB-Installer-1.9.0.2 as instructed and choose the "Ubuntu 12.04 desk top" option, after downloading the respective iso/zip file onto my Dell laptop from the Ubuntu site. Also modified my bios to select the usb first as boot drive instead of hard drive. Also, turned off bit blocker on my laptop and usb stick. Usb stick has the setting of "Automatically unlock this drive on this computer". When i reboot my laptop, it first boots into a black screen (i assume is the bios), but prompts saying "Remove disks or other media. Press any key to start". I press any key and regardless the laptop boots up to windows. Hence, it appears that the boot process is checking the USB first before going to the hard drive to look for it's boot disk and starting Windows 7. Is it that the USB stick is not correctly configured with Ubuntu as a boot disk? Is there anything else that i need to do besides the instructions at the following link? http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows How can I ensure that USB boot stick is configured correctly? After running the Universal-USB-Installer-1.9.0.2 to "install" Ubuntu, is there additional configuration/installation steps? What is the first file that the bios would look for on this USB drive? Is this configured somewhere in the bios, or would it just look for an grub file or /boot dir? The only message i get when booting is "Remove disks or other media. Press any key to start". Any and all help would be much appreciated.. Thanks ... :)

• automate operations within a Virtualbox machine

  - by samb

  Hi, I'm Having some trouble in a vm that seems to occur only once in a hundred during shutdown/reboot. To help the debug, I'm thinking to write a script that runs on my desktop, which starts the vm and automate operations for a huge number of times (keyboard key pressed) whithin it. (VirtualBox preferred). It's just exactly how a script using the expect lib would do with a program in command line. I'm not sure it's possible, but anyway, if anyone has an idea... Cheers

• Why can't I install 10.04 on a system that already has 8.04?

  - by Android Eve

  Ubuntu 10.04 is beautiful. I love it. I am dying to install it on my PC, alongside the existing Ubuntu 8.04 (from which I write this message right now). But... it won't let me! When I reach the partitioning stage (manual!) Ubuntu 10.04 sees my two HDDs as one RAID volume. It doesn't see all the partitions I already have in place in /dev/sda and /dev/sdb. Even Windows 7 doesn't behave like this... (yes, I actually managed to install Windows 7 64-bit in dual-boot configuration with Ubuntu 8.04 on this same system). Note: GParted on Ubuntu 10.04 (live CD) sees the partition intended for Ubuntu 10.04 (/dev/sda4) perfectly, but is unable to format it. Note: I also removed that partition trying to reformat it via GParted once 10.04 LiveCD is loaded. It didn't help. I believe that the problem lies in Ubuntu "deciding for me" that the HDDs should be "seen" as a RAID, hence any partition is seen by GParted as "busy" or "locked". Any idea how to solve this problem?
