• Is it possible to install Ubuntu 10.10 and/or Ubuntu 11.04 on a late 2009 iMac?

  - by Oliver

  I would like to install Ubuntu on my iMac 10,1 (21.5 inch display). I would prefer to instal Natty Narwhal, but would surely settle for Maverick Meerkat (which I have a install dvd of). I have an install of OS X Snow Leopard AND a Bootcamp Partition of Windows 7. I would like to keep all these partitions and setup a triple boot system. If it can work, I'm also wondering if it'd be safe to install all updates from the update manager once it's installed. Thank you in advance. :)

• Ubuntu 13.04 ERROR: /etc/apt/sources.list not found

  - by Richard Riley

  So, I tried uninstalling the LAMP stack I had following the Ubuntu documentation for it. I also manually removed dbconfig-common. Now, I'm unable to run apt-get update. When I do, I get the error message: E: The method driver /usr/lib/apt/methods/htp could not be found. After some digging, I've discovered that I no longer even have an /etc/apt/sources.list file. Also, I've received an error, when trying to run: sudo tasksel install lamp-server That aptitude can not be found. Does anyone have an idea of what I can do? I'm not able to find any documentation online that works - all the documentation out there is dated and no longer (or will not) work with 13.04. I followed this link previously prior to posting my question and it did not work for me: How do I fix a "E: The method driver /usr/lib/apt/methods/http could not be found." error?

• Gnome 3 Shell extensions not working on Ubuntu 12.4 [closed]

  - by user63960

  Possible Duplicate: Gnome Shell Extension Empty I just upgraded to Ubuntu 12.4 running on a Win 7 box via VBox and switched the user interface to Gnome 3 but have a problem. In Advanced Settings (gnome tweak), the Shell Extensions window has no listings and the Theme window shows a "caution" triangle next to the Shell theme drop box. I have re-installed the default extensions using the Noobs Lab posted instructions: sudo apt-get install shell-extensions3.4 sudo apt-get install gnome-shell-extensions The commands appear to complete without error. Symptoms are: Gnome 2 visual appearance and no window borders or controls. To close a window, I have to click the window indicator in the sys tray and select the close menu item. Any ideas?

• ubuntu 11.10 on MacBookPro 7,1 can only see one cpu

  - by gozzilli

  On a MacBookPro 7,1 running ubuntu 11.10, System monitor only sees 1 core (instead of 2). cat /proc/cpuinfo | grep 'cpu cores' also gives: cpu cores : 1 I followed this guide and added acpi_apic_instance=2 to the line with GRUB_CMDLINE_LINUX_DEFAULT, but that doesn't seem to change the situation. What can I do? I'm using rEFIt, installed under MacOS, and running in dual boot with MacOS. After the rEFIT menu, I'm still presented with the GRUB menu (I'm assuming that's normal). I saw similar posts on this matter, but could not fix my problem with what they suggested. Any help appreciated. Thanks!

• When Ubuntu Server restarts eth0 Doesn't come back up

  - by JoelGsus

  Every time I restart my Ubuntu Server 11.10 I can't ssh into it because ETH0 doesn't come up automatically. I never had this problem before upgrading to 11.10. I have to login to the server and start the ETH0 manually. I would appreciate it any help. Thanks. Here is my /etc/networks/interfaces file: #The loopback network interface auto lo eth0 iface lo inet loopback # The primary network interface iface eth0 inet static address 192.168.1.102 netmask 255.255.255.0 broadcast 192.168.1.255 network 192.168.1.0 gateway 192.168.1.1

• HP 655 Notebook (Ubuntu 12.04) wireless internet disabled after running updates

  - by Bastian

  Today the update-manaeger suggested that I should download some updates. So I did. After the updates were installed I had to reboot the system. After the reboot my notebook doesn't see any wireless networks. I was looking for a long time on the internet for answers but non of them applies to my case. I have the idea, it has got something to do with the kernel I am currently using (Linux 3.2.0-55). Is this one new for Ubuntu 12.04? When I boot my system I can choose to use an older kernel (linux 3.2.0-32). When I use this one the notebook does see the wireless networks. This is my network card according to the command lspci: Ralink corp. RT3290 Wireless 802.11n 1T/1R PCIe Anyone an idea to fix my problems with wireless internet?

• Ubuntu Gnome 14.04 - 100% CPU usage alternating between cores

  - by AwDeOh

  I've noticed my Ubuntu Gnome 14.04 has been getting a bit sluggish lately - things like Gnome Shell overview animation are jerky where they were lightning fast, Elder Scrolls Online is stuttering and dropping to low FPS where I previously had a solid 50-60 fps. Out of interest I looked at the CPU History, and when running nothing but the system monitor, I was getting this: That was 15 minutes ago. The 100% load seemed to be alternating between the cores. PC specs: i3 2130 processor. 8gb DDR3 RAM. ASUS P8-Z77M motherboard. Samsung 128gb SSD I've been trying to reproduce the problem, and while I'm not getting the 100% any more at idle, the system monitor is showing an average load of about 20-30%, that's with just Chrome and the System Monitor open. Oddly, if I touch nothing, it'll average out to about 20% - if I start moving the mouse around and do some typing, it's closer to 40%. Is this normal? Any help appreciated, I wouldn't even know where to start here..

• Where should people give feedback on Ubuntu?

  - by poolie

  Many people have opinions or want to give feedback about Ubuntu. If they are simple bugs with a crash or display corruption, that's fine, they can file in Launchpad. But, comments about the design or concept of the system are more problematic. They come up all over the place, such as "Some Unity feedback" in other places that are not really about Unity. Ideally the answer will be a place where the comments will actually be read by the design team will tend to encourage people to read the existing comments and not post the same thing again and again perhaps will tend to bubble up good solutions rather than strange ideas will not be annoying to people who are trying to use that place for something else

• Ubuntu Wifi Not Connecting (And keeps asking for authentication every minute or so)

  - by kelvinsong

  This is a problem in 12.10 that has been driving me nuts, and it's a problem with the wifi. Ubuntu will never connect to the network. All of my other devices work fine. What will happen is I will type in the password, the authentication window will go away, and the Wifi icon will pulsate for a while. Then about a minute later, a window will pop up asking for authentication to join the same wifi network. If you type in the password again it will do the same thing, and even if you hit [Cancel], the window will still pop back up in another minute. This is a very irritating thing.

• Set up Trendnet TEW-638APB Access point on Ubuntu 14.04

  - by Mr. Smileys

  I have a computer running Ubuntu 14.04, it has 2 Ethernet ports. I would like to set up this computer so that the internet comes in on one of the ports and is then shared through the other port with the Trendnet wireless access point that my other devices would connect to and use the internet. I have looked online for information on setting this up but have not been able to find anything. If someone could point me to a guide that would help me or just tell me how to do this in an answer I would really appreciate it. please help me to solve this problem

• x11 Remote Desktop with Ubuntu 12.04

  - by BSchlinker

  When I was running Debian, I was able to start a remote session over x11 by just typing gnome-session However, with Ubuntu 12.04, this only seems to result in my desktop and background being forwarded over x11 -- the top bar (where the clock is) and dock are both missing. I tried starting all of unity by executing unity, but that just resulted in a segfault. How can I start a Unity 2D session over x11? Edit: I prefer x11 as I need to tunnel the connection over 2 other servers. I would need to do a good amount of port forwarding within SSH to get any other connections back. Of course, if someone has any other suggestions, I'm willing to listen.

• Pppoe wireless connection, Ubuntu 12.4

  - by Barbara

  I recently bought a new computer (Asus 1015 cx) with Ubuntu (12.4) as preinstalled system. My problem is with the internet. The computer connects just fine to the free wifi we have at home, but in college, we have a little bit different system. There is wifi, but it is not free - everyone receives a user name and a password. I cant manage to estabilish this Pppoe connection - the computer "sees" where can it connect, but I dont know where to write my username and password. It is not the DSL connection, what I have already tried. Can you help me?

• How to use unused space in ubuntu

  - by Ravi.Kumar

  I installed ubuntu on my machine with only 80 GB of memory anticipating that I will remove it later but now I want to keep it forever (until I am frustrated with linux). I have 500 GB in my machine and now I want to use that raw 420 GB of space. How I can I do that ? with "space/memory" I am referring to secondary memory not Ram.

• How to fix Bluetooth Sound in Ubuntu 11.10

  - by Cerin

  Bluetooth sound worked perfectly for me in Ubuntu 10.04. I recently upgraded to 11.10, and although sound in general works fine, Bluetooth sound almost never works. My headset is paired, and Sound Settings shows it's selected as the output device, but no sound is being output. I've tested the headset with other devices, and confirmed it still works, so the issue is definitely with 11.10. I'm not seeing any explicit errors and I can't find any similar issues with 11.10 through Google. I tried restarting the bluetooth service, but that had no effect. What can I do to fix this?

• KDE fonts not rendering bold in Ubuntu 12.04

  - by Doran

  I'm using Ubuntu 12.04 with some KDE programs: kate and yakuake. Neither of these programs will render bold font. Instead, the font appears as "Regular". How can I fix this? The image below shows an example of Kate rendering python with the stock python highlighting (the colors are inverted using CompizConfig Settings Manager's Negative option). The following words should have appeared bold: class def __init__ lambda + print Similarly Yakuake (or perhaps, the underlying Konsole) is not rendering bold. My LS_COLORS includes: di=01;34 (bold blue) Below is my gnome-terminal rendering bold fonts just fine.

• Unity environment way too slow in Ubuntu 13.10

  - by Santiago

  Unity and its apps open too slowly whenever I open one. It takes a while for them to appear completely. Everything works properly when the window is already open. The biggest problem is with the dash: it's SO SLOW when I'm looking for an app although I have removed some lenses. What should I do or what can I do? These issues only occur with Ubuntu 13.04 and 13.10 whereas 12.04 works AMAZNGLY but I have issues when updating a package or installing a new one, that's why I don't opt for that one. Specifications: RAM: 2GB, Processor: Intel® Atom™ CPU N2600 @ 1.60GHz × 4, Graphics card: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits)

• Problem with keyboard and trackpad on ubuntu 12.04

  - by Cdub

  Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

• upgrade from ubuntu 12.04 to 12.10 failed, now loads "grub rescue"

  - by Greg

  I attempted to upgrade from 12.04 to 12.10 last night. Installation seemed to go fine, and this morning I had a message like "restart now to complete installation". So I restart, get an initial "Loading Operating System ..." message, followed by "error: file not found. Then it kicks into "grub rescue" mode. Previously I have this running as a dual boot (window 7) and I just ran the upgrade to 12.10 via the update manager in ubuntu. Any ideas on what is going on here, or what the error means? I know my way around the command line, but this is above my pay grade. Thanks for any advice.

• Trick Ubuntu into resolving a domain name locally

  - by Matthew Brown

  I have an Ubuntu box that I use for all sorts of things. One thing I really want to do is redirect a sub domain to a local script. For example thisbit.example.com should actually show the content from localhost/~USER/FAKE.thisbit.example.com/ which is a folder that Apache is running for me which contains a very simple PHP script which implements an offline version of a server script that I am testing against. But example.com should continue to behave normally as should notthisbit.example.com etc. Ideally I need to be able to switch from testing to live with minimal fuss when the time comes.
