I installed Ubuntu on my external hard drive but it won't boot on my laptop. It works fine on my desktop but not my laptop. It says it can't find root... what do i do?
I noticed that the username I used to install Ubuntu got added to a bunch of groups in the /etc/group file. I'm getting rid of unneeded accounts. Would anything break if I removed that first account?
What is the standard/correct way to re-install grub2?
I am using liveusb right now and i am unable to boot into Ubuntu on my hard drive.
Partitions are as follows:
/dev/sda1 1 3917 31463271 7 HPFS/NTFS
/dev/sda2 3918 10444 52428127+ 7 HPFS/NTFS
/dev/sda3 10445 15671 41985877+ 7 HPFS/NTFS
/dev/sda4 15672 19457 30411045 5 Extended
/dev/sda5 * 15672 17711 16386268+ 83 Linux
/dev/sda6 17712 19457 14024713+ 83 Linux
Pleas help.
thanks
i have ubuntu 10.10 x86_64 with nvidia 9800 gt and nvidia driver version 270.41.06
my video card has two DVI sockets, but i only use single monitor configuration. Now, i think the main DVI socket might be busted, so i want to try to enable the other as the main one, however, i don't know how to achieve that. I tried just plugging the monitor in that socket but it won't just auto-detect (it would have been way too easy to just work)
Which command should I use to download security uodates for Ubuntu Hardy?
Ideally would like the command to also create a log file listing files downloaded, install and any errors.
Thanks for help.
I have set up a Ubuntu PC on a next work that is behind a ISA Proxy.
When I run the command
sudo apt-get update
I get several messages with this message:
502 Proxy Error (The ISA Sever denied the specified Uniform Resource Locator)
The computer can see the internet and adding the proxy settings in the Network Preferences does not help. When I do a ifconfig Im on a 192 address which is not the usual subnet our PCs are on.
Any ideas?
I can't wrap my brain around the new pam.d configuration syntax used in Ubuntu 10.04. How do I setup PAM so that it allows users stored in my LDAP database to login.
I already configured nscd, so id <user> or getent passwd are already listing my LDAP users, but PAM doesn't work, whether the normal shell login nor su.
I have a small java project that handle connections.
In order to run it from the terminal I have to cd into the folder that contains the source and run the following command:
java -cp classes com.packagename.mainclass
Where classes is the folder that contains the classes.
I want ubuntu to run this application on startup, is there a Java command I can use? Or am I just better off creating a shell script?
Thanks!
I use Ubuntu 11.04 and Gnome 2.32.1.

I have Ubuntu 10.04 guest on Windows XP host. I need to use a specific VPN software that works only on Windows. How should I configure virtualbox/guest so that the VPN connection would be visible on guest?
I already tried NAT and bridged network settings. With both of these options I get only normal internet connection to work, but sites requiring VPN don't work on guest, only on host.
Hi here
I'm planing to buy a laptop or mini-laptop and use a Ubuntu OS on it. The thing is that i really need it to use it many hours on batery mode. I'm thinking that i'll have troubles in finding the right rivers and my batery to be waisted. What other problems can I have?
Also, I wana use the laptop or mini-laptop outside/outdoor. What display technology is most recommended for that?
Normally when I read a book I use a bookmark held horizontally under the current line I'm reading to help me keep my eyes on the right spot. When I read a PDF or other document on my computer I would like to be able to do the same thing, only with a line on the screen controlled by the up and down arrow keys. Any suggestions for an application which would do this? I'm a Ubuntu Linux user.
I've installed ubuntu 10.04 LTS, and ran apt-get install couchdb. This installed 0.10.0, however the newest is 0.11.0 and I would like to install that from source.
What's the appropriate way of upgrading the current install to the newest version?
I am new to Ubuntu(and Linux for that matter) and I am trying to access files using the terminal. The network folder is on my Desktop, but when I go to the Desktop folder via the terminal, the network folder is not there.
How do I access files on a network folder via the terminal?
I'm using Firefox 3.5.9 in Ubuntu 9.10. The "Clear recent history" menu item on the Tools menu is greyed out. I tried launching Firefox using sudo from the command line, but no luck. What gives?
In my Ubuntu8.04 'Other' menu, it has 'OpenJDK Java 6 Runtime', 'Sun Java 5.0 Runtime' , 'Sun Java 6 Runtime'.
Can you please tell me where are these actually installed?
I can only fine 1, the OpenJDK :
$ which java
/usr/bin/java
$ java -version
java version "1.6.0_0"
OpenJDK Runtime Environment (build 1.6.0_0-b11)
OpenJDK Server VM (build 1.6.0_0-b11, mixed mode)
How can I find the others?
Thank you.
This is perhaps the most bizarre problem I've ever come across, but my home directory in Ubuntu 9.10 seems to be occasionally reverting to a previous state.
For example, I'll change a setting in Opera (whose settings folder is in my home directory), then upon subsequent restart, may or may not have reset to what it was previously. This happens with all programs with settings in the home directory.
I have the Kubuntu desktop downloaded as well, so I am using KDE4. Any ideas?
I have an Ubuntu 10.10 EBS boot server on EC2. There are new updates available for it:
linux-image-virtual
linux-virtual
Is it even ok to upgrade those packages on an EC2 server?
When I do try to upgrade them I get:
The following packages have been kept back:
linux-image-virtual linux-virtual
Should I do a dist-upgrade or something to force it? Will my instance be able to be rebooted?
I'm running Ubuntu Squeeze and on one of the partitions df is showing the Total size as 335G:
Filesystem Size Used Avail Use% Mounted on
/dev/sdb 335G 225G 94G 71% /mnt
However in the past it was showing as 360GB (which is the actual size):
fdisk -l /dev/sdb
Disk /dev/sdb: 365.0 GB, 365041287168 bytes
lsof +L1 does not return anything (and anyway if this would be the case the Total space should not be affected.)
On this partition I'm writing (and deleting) a lot of files and this happened before in the past, but problem solved by itself.
