ISO booting with grub2 in Ubuntu on an Apple

- by Robert Vila

I have Ubuntu with grub2 installed in an Apple Macbook pro with dual boot (using rEFIt), and I would like to use grub2 to boot the LiveCD ISO image of a system based in Debian too (CrunchBang). The ISO image is saved in the same hard disk, same partition as Ubuntu. I can easily boot many other LiveCD ISO images, but I cannot boot this one, and I cannot boot the MacOS system, from the grub menu, either. The installation of Ubuntu left a couple of menu entries to boot MacOS, but they never worked. SO I don't know if it is possible to boot them, and how. I have tried many options, but the menuentry I am trying now to boot crunchBang is this one: menuentry "crunchbang-10-20120207-i386.iso" { set isofile="/home/user/Desktop/ISO/crunchbang-10-20120207-i386.iso" loopback loop (hd0,3)$isofile linux (loop)/live/vmlinuz1 iso-scan/filename=$isofile toram=filesystem.squashfs findiso=$isofile boot=live config -- initrd (loop)/live/initrd1.img } And I copied it from here: http://linux4netbook.blogspot.com.es/2012/08/due-crunchbang-e-un-pennino.html

Ubuntu Desktop Environments, No Internet Access

- by Sneha429

Windows has been a pain, so I installed Ubuntu 13.10 on my parent's HP Pavilion first with Cinnamon. For the first few days, it worked wonderfully, and then stopped connecting to the internet. I tried using the windows partition and it worked fine. Posted a question about this - no answer yet. Since then, something happened while my parents were using it. The Windows partition was completely erased. I reinstalled Ubuntu and the Cinnamon desktop. Worked great for a day, then same connectivity issue. Since Ubuntu works fine on my netbook without Cinnamon, I thought perhaps this was a Cinnamon issue. Removed Cinnamon and installed LXDE. LXDE, much like Cinnamon, worked well. Then I rebooted and couldn't connect to the internet. I encountered the same issue when using KDE. I would personally like something with a bottom panel as my parents are familiar and comfortable with Windows and can barely use their cell - phones so I do not think Unity will work too well for them. Ubuntu with Unity seems to be the only way to access the internet. My parents mostly use the internet to check email/facebook/watch video. Anyone know how to fix this?

Why are two indicator-network versions being worked on?

- by Daniel Rodrigues

Some months ago, on the road to Ubuntu Maverick, a new system indicator, network (with connman as a backend), started to be developed. The plan was to get it into UNE and release it with no notifcation area. Unfortunately it didn't make it into the final version. However, continued efforts are still being made to improve it, and I'm getting regular updates. From a blueprint from the last UDS, I read that the plan was to ship no notification area and only indicators. For that, it was defined that nm-applet (backend: NetworkManager) should be ported to the appindicator library. Today I discovered that those efforts are going on and a initial version is available for testing, available from Matt Trudel PPA (Natty only). So, my questions is, to whoever has the necessary info: wouldn't it be easier to join efforts and concentrate the work in just one version (probably NetworkManager backend, as that's the official plan), instead of breaking those efforts apart and hampering both testing and developing? Both indicators are being developed by Canonical engineers, and that really doesn't make much sense. So, any Canonical engineer willing to clarify this?

Ubuntu USB boot failure

- by Steve

When trying to boot from a boot USB drive I got the message, "Vesamenu.c32:Not a com32r image." I was trying to boot a fairly new Toshiba laptop with a Ubuntu 10.04.2 LTS created USB boot. I re-created the USB drive with 11.04 and it booted fine. These were both 32 bit versions even though the laptop is a 64 bit. I was trying to create a generic boot USB that would work on everything I might try it on. What is the consensus on this idea? Any solution to the above error? Thanks from a noobe.

High load (and high temp) with idle processes

- by Nanne

I've got a semi-old laptop (toshiba satellite a110-228), that's appointed 'laptop for the kids' by my sister. I've installed ubuntu netbook (10.10) on it because of the lack-of memory and it seems to work fine, accept from some heat-issues. These where never a problem under windows. It looks like I've got something similar to this problem: Load is generally 1 or higher, sometimes its stuck at 0.80, but its way to high. Top/htop only show a couple of percentage CPU use (which isn't too shocking, as i'm not doing anything). At this point all the software is stock, and i'd like to keep it that way because its supposed to be the easy-to-maintain kids computer. Now I'd like to find out: What could be the cause of the high load? Could it be as this thread implies, some driver, are there other options to check? How could I see what is really keeping the system hot and bothered? How to check what runs, etc etc? I'd like to pinpoint the culprint. further steps to take for debugging? The big bad internet leads me to believe that it might be the graphics drivers. The laptop has an Intel 945M chipset, but that doesn't seem to be one of the problem childs in this manner (I read a lot abotu ATI drivers that need special isntall). I'd not only welcome hints to directly solve this (duh) but also help in starting to debug what is going on. I am really hesitant in installing an older kernel, as I want it to be stock, and easy upgradeable (because I don't live near it, it should run without me ;) ) As an afterthought: to keep the whole thing cooler, can I 'amp up' the fancontrol? Its only going "airplane" mode when the computer is 95 Celcius, which is a tad late for my taste. Top: powertop:

Synaptic won't launch from menu in panel in fresh Lubuntu minimal desktop 12.04 install

- by ven42

I performed a fresh install of Lubuntu 12.04 with minimal desktop, as described here: https://help.ubuntu.com/community/Lubuntu/Documentation/MinimalInstall. To clarify, I did a command-line install from the Lubuntu alternative install disc, then I did an "apt-get install --no-install-recommends lubuntu-desktop". Everything is working fine, except that Synaptic will not run from the menu entry in the panel. I am not prompted for a password, and no window of any sort appears after clicking the menu entry. I installed lxshortcut to see what the shortcut was running, and the command is "synaptic-pkexec". If I type this command into the "Run" menu, I get the same behavior (or lack thereof). I can get Synaptic to open up just fine by typing "gksudo synaptic" at the "Run" menu. Also, if I run "synaptic-pkexec" from the terminal, then I am prompted for my password within the terminal, and after that Synaptic opens normally. Can someone please suggest the right way to get Synaptic working? I could just change the menu entry to "gksudo synaptic", but I'm guessing that it's set to "synaptic-pkexec" for a reason. I have a vague understanding that this pkexec business has something to do with PolicyKit, but I don't really know what PolicyKit is or how to tell if something is broken with it. Thanks.

sudo dhclient eth0 | sudo: unable to resolve host ubuntu

- by Merianos Nikos

I have a computer of a friend of mine, that runs Ubuntu (I don't know what version, due to the current system status) and while he was updating the kernel, he reboot the computer (yes that could be happen !!, anyway) Currently I am trying to recover the system by using a live USB, with Ubuntu installed on it. What I am doing, is the following: Update Failure The problem is that when I try to execute the fifth step, I am getting error because I do not have Internet access. The computer is properly wired on my rooter, and I have Internet access in any place apart of the shell. This message for example is send it via the live USB. but I cannot access the Internet via the shell. In my shell I try to use this command: sudo dhclient eth0 but the result of this command is the following message sudo: unable to resolve host ubuntu My hosts file has the following content: 127.0.0.1 localhost 127.0.1.1 ubuntu # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters ff02::3 ip6-allhosts how can I get connected on the Internet, in order to download the appropriate updates ? UPDATE 1 I just notice, that when I execute the ifconfig I am getting the following warning: Warning: cannot open /proc/net/dev (No such file or directory). Limited output. UPDATE 2 I just found that, and looks like solving the problem with dhclient eth0 command, but still I cannot ping Google UPDATE 3 Now the sudo dhclient eth0 returns the following message: RTNETLINK answers: File exists UPDATE 4 I just ping my rooter and I getting response, so, it is looks like I cannot ping outside the rooter (ie. Google) Kind regards ...

Encrypting a non-linux partition with LUKS.

- by linuxn00b

I have a non-Linux partition I want to encrypt with LUKS. The goal is to be able to store it by itself on a device without Linux and access it from the device when needed with an Ubuntu Live CD. I know LUKS can't encrypt partitions in place, so I created another, unformatted partition of the EXACT same size (using GParted's "Round to MiB" option) and ran this command: sudo cryptsetup luksFormat /dev/xxx Where xxx is the partition's device name. Then I typed in my new passphrase and confirmed it. Oddly, the command exited immediately after, so I guess it doesn't encrypt the entire partition right away? Anyway, then I ran this command: sudo cryptsetup luksOpen /dev/xxx xxx Then I tried copying the contents of the existing partition (call it yyy) to the encrypted one like this: sudo dd if=/dev/yyy of=/dev/mapper/xxx bs=1MB and it ran for a while, but exited with this: dd: writing `/dev/mapper/xxx': No space left on device just before writing the last MB. I take this to mean the contents of yyy was truncated when it was copied to xxx, because I have dd'd it before, and whenever I have dd'd to a partition of the exact same size, I never get that error. (and fdisk reports they are the same size in blocks). After a little Googling I discovered all luksFormat'ted partitions have a custom header followed by the encrypted contents. So it appears I need to create a partition exactly the size of the old one + however many bytes a LUKS header is. What size should the destination partition be, no. 1, and no. 2, am I even on the right track here? UPDATE I found this in the LUKS FAQ: I think this is overly complicated. Is there an alternative? Yes, you can use plain dm-crypt. It does not allow multiple passphrases, but on the plus side, it has zero on disk description and if you overwrite some part of a plain dm-crypt partition, exactly the overwritten parts are lost (rounded up to sector borders). So perhaps I shouldn't be using LUKS at all?

Ubuntu Won't Load Up

- by Russ

I'm having trouble with Ubuntu. It was working fine on Weds 24/08/12. Fired up my laptop yesterday and came up with the Grub screen. What I basically want to know is how do I get back to normal service? I'm pretty illiterate when it comes to Ubuntu/Linux systems. I think I'm running the latest version of Ubuntu. Currently using the 11.10 trial which I burnt to disc to use my laptop at the minute to post this question. This is the first screen I get come up. 'http://img.photobucket.com/albums/v419/R1187/20121025_173033.jpg' Following the first option it just takes me to a black screen with a flashing underscore. Pretty sure it doesn't allow me to enter any text. When I follow the second option I get this screen: I've tried following the advice on this question, but it hasn't done the trick. It keeps asking me if it's mounted. Any help will be appreciated. Ideally I'd like to get things back to normal. Failing that copying my data from the hard drive to an external one and reinstalling Ubuntu would be fine.

Install Ubuntu 12.04 on a ACER AC100

- by pidarn

I'm trying to install a 12.04.1 on an ACER AC100 - Mini-Server. After booting from the Install-CD there are no Disks shown. In Bios I disabled the Intel-Raid /LSI-Raid. I want to install on the 1st of 4 "native" disks and I tried to do this with RHEL 6.4 where all Disks are visible - but the UBUNTU-Installer doesn't find any of them. btw ... If I boot from the UBUNTU - Install-CD in "rescue"-mode the disks are visible?! Any Ideas?

Some problems after running ubuntu tweak application

- by sachin

I am a first time user of ubuntu 12.04 and must say that i am enjoying it. Somehow my skype on ubuntu is screwed up. The message that i am getting says (Disk IO error). Did any one face the problem before. Also i downloaded the ubuntu tweak application. After that application has clean some file, the application it self is not starting now.. I am quiet new to linux much and fear that if the tweak application has cleaned some files which were necessary. Is there anything i can fix these problems or short of auto-recovery, i have got some more leads: here seems to be the error but not sure how can i fix this. buntu-tweak:2887): Gtk-WARNING **: Locale not supported by C library.

Do we really need a thousand Linux distributions?

- by nebukadnezzar

Pointed from an answer to a (possibly related) question, I came across this graphic, and I'm shocked how many linux distributions currently exist. However, it seems that most of these distributions are forks of already popular distributions with minimal changes, usually limited to themes, wallpapers, buttons, the kind of stuff most people probably wouldn't see as a reason to fork a Linux distribution. Of course, someone will always say "Opensource is also about the freedom of choice", and while I wholeheartedly agree, I do not believe that this is a valid reason to fork an already perfectly working Distribution into a new one, which might possibly result in less security/stability due to smaller group of developers. There's another problem: Those, who want to switch to Linux, are confronted with a neverending list of Linux distributions, and wonder rightfully which they're supposed to chose (infact, I was facing that problem before I've discovered Ubuntu). There might be (very few) valid reasons to fork a distribution: Specializing on a particular topic (FOSS Only, work-related topic (i.e., for a Hospital), etc) An exceptional architecture, that requires a special set of software Use of non-FOSS, propietary technology, and such But even with these points in mind, it would still seem easier to create a subdistribution with the required changes, such as XUbuntu with XFCE4, KUbuntu with KDE4, Fluxbuntu with Fluxbox, etc. So, why exactly do we need so many distributions?

OS X Mavericks Won't Connect To Ubuntu Server (Netatalk, Avahi)

- by Andy Ibanez

I'm really sorry for posting this. I know it may have been asked a thousand times. I have googled like crazy and I'm on the verge of desperation here. Basically, I followed this guide: http://motionsoundfx.com/2012/05/ubuntu-vnc-afp-macosx/ To create a small personal file server. When I installed it, I was able to connect to it just fine, I connected with my Ubuntu username and password and I was able to see the home directory. But later, I had to restart the file server so I could prepare a couple of other hard drives to put in. When the server restarted, I tried to connect to it, but I got an error message on my Mac: "The version of the server you're trying to connect to is not supported. Please contact your system administrator to solve this problem." Again, I have googled like crazy for this, and everybody says it is a problem with OS X Lion and up (assuming it affects Mavericks too). I have tried all the fixes mentioned for Lion and Mountain Lion and I haven't had any luck. That's the reason I'm posting this here: I suspect the problem is with my Ubuntu server. This happened after I restarted the server. Before restarting the server, I just put in my credentials and saw my home directory. Something when I restarted the server must have been messed up. I have found some other solutions, including to use "SHX2" in the conf file, but it hasn't worked for me. I ask for your help to solve this issue. Also please understand I'm completely illiterate when it comes to Linux. This is a nice chance to me to learn the OS so please give me detailed steps to do things if you deem it necessary. Thank you! I'm using Ubuntu Server 13.10 (the latest one as of today).

Wacom Bamboo CTH460L issues in Ubuntu 10.04

- by Robert Smith

I recently bought a Wacom Bamboo Pen & Touch CTH460L. I installed doctormo PPA, however, the pen functionality didn't work and the touch was very glitchy (when I touched it, it immediately double clicked and began to drag elements in the screen). I tried to configure it using the wacom-utility package in the Synaptic Package Manager (version 1.21-1) but that didn't work either. Then I followed this post (#621, written by aaaalex), and after some problems trying to restart Ubuntu (graphics related problems), the pen works fine (it could be better, though) but the touch functionality doesn't work anymore. Currently I have installed xserver-xorg-input-wacom (1:0.10.11-0ubuntu7), wacom-dkms (0.8.10.2-1ubuntu1) and wacom-utility. The Wacom Utility only displays an "options" field under "Wacom BambooPT 2FG 4X5" but no other option to configure it. What is the correct way to get this tablet working on Ubuntu 10.04?. By the way, currently I can't start Ubuntu properly when the tablet is connected (in that case, Ubuntu start in low graphics mode). I need to connect it later.

ubuntu 11.10 foreman error

Can't add NetworkManager applet to gnome panel

- by Nate

I have researched this problem extensively and I can't seem to find an answer. In Ubuntu 10.04 LTS, I want to connect to my VPN through the NetworkManager applet. I installed all the network manager packages, including the gnome client. I understand I need to add the "Notification Area" to the panel, which I have done. I checked that the NetworkManager is running: nate@nate-desktop:~$ service network-manager status network-manager start/running, process 763 In /etc/NetworkManager/nm-system-settings.conf, I have added managed=true (don't know if this matters, but I saw it suggested on one forum): nate@nate-desktop:~$ more /etc/NetworkManager/nm-system-settings.conf # This file is installed into /etc/NetworkManager, and is loaded by # NetworkManager by default. To override, specify: '--config file' # during NM startup. This can be done by appending to DAEMON_OPTS in # the file: # # /etc/default/NetworkManager # [main] plugins=ifupdown,keyfile [ifupdown] #managed=false managed=true I restarted NetworkManager and tried rebooting, too. At this point, it looks like NetworkManager is running but it's not appearing in the NotificationArea of the panel. I don't know what else to try. Any ideas?

Ubuntu not shutting down ( going to black screen ) 12.04

- by Orrin Fox

I am currently using a USB persistent install of ubuntu. its a simple 4GB drive with a 2.8GB partition ( casper-rw storage partition ). I setup an administrator account and set it to login automatically. I also removed ubiquity to simply use this as a go anywhere install. Heres my issue. Im logged in as my account, and I click the top right gear and select "shut down". Text pops up showing its quitting processes.. etc. and then goes to the plymouth animation. But... The screen goes black, and then it goes to the login screen. Now when im at the login screen i go into terminal ( alt+F2 ) and dont you know, im logged in as Ubuntu. so then I try the following: ubuntu@ubuntu:~$ sudo shutdown now It goes to the plymouth screen again as if its shutting down, AND the screen goes black once again but the computer has not turned off, as in the usb is still flashing the light, the fans are still on, the only thing off is the screen. Is this a bug? If not maybe i did something wrong? Perhaps its that I made an account but... if there is a work around for this please let me know. Thanks again, Fox

Ubuntu 12.10 loud fan noise hp compaq 615

- by Levente Nagy

I am totally new to Linux, i installed it yesterday, since than i my fans are really loud, i did not have this problem on windows. I saw this post on this site How to control fan speed? But i am totally lost with it because im a new user to Ubuntu when i arrive to that page i see these lucid (utils): utilities to read temperature/voltage/fan sensors 1:3.1.2-2: all precise (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu1: all quantal (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.1-2ubuntu2: all raring (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.2-2ubuntu1: all saucy (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all trusty (utils): utilities to read temperature/voltage/fan sensors [universe] 1:3.3.3-1ubuntu1: all So what is lucid? trusty? saucy? and other? i thought its some kind if a ubuntu type (sorry for beeing silly here) i checked my ubuntu version it just says Ubuntu 12.10 So which one i need to download? I saw there are terminal commands, im new to that too, will it cause some problem if i just copy and paste? PS: I saw my graphics card is undetected as well i have a ATI Mobility radeon HD 3200, could that cause the problem too?

Firefox 15 hangs with Ubuntu kernel update

- by Marty

I recently ran updates and it told me that in order to get those updates I had to update my kernel. I did that and also updated Firefox to 15. Since then Firefox hangs/gray screens sites I go to. This lasts anywhere from 5-10 seconds to 2-3 minutes. I have restarted Firefox with all add-ons disabled but it still did the same thing. I found a bug report on Launchpad that sounded like what was happening with me, but I haven't received any error codes, just the hanging/frozen screens. Also it seems that it ups my CPU making the rest of Ubuntu lag while Firefox is hung. I would guess the cause is a conflict between the updated kernel and the updated Firefox, but I'm still fairly new at Ubuntu and not sure where to go from here. Is there anything else to try? My Toshiba laptop specs are: Ubuntu 12.04 (32 bit) Linux 3.2.0-30-generic-pae #48-Ubuntu SMP Fri Aug 24 17:14:09 UTC 2012 i686 i686 i386 GNU/Linux Firefox 15.0.1 Intel® Pentium(R) Dual CPU T3400 @ 2.16GHz × 2 Mobile Intel® GM45 Express Chipset x86/MMX/SSE2 Thanks!
