• Ubuntu firefox: some web-pages stuck on loading

  - by kristaps.skujins

  Just installed Ubuntu 10.04 beta, installation went fine and all programs are working smooth. Just this one weird network problem. Some sites simply are not opening and loading forever. For example, google.com and youtube are working well, but ubuntu.com and many other are not opening at all, or are loaded partly. One thing i noticed is that on all of those pages on firefox status bar is message "Looking up for www.google-analytics.com" (or similar remote resources) message appearing all the time (even on this page, but it somehow has loaded and working). I should mention that i tried those pages to open on windows OS on this same machine, and they opened without problems. So i am guessing that it has to be some sort of network configuration problems on Ubuntu. What could cause such problem?

• Dell Latitude E6420 dual-boot Ubuntu + Windows 7 Optimus graphics problems

  - by Ryan

  I have a Dell Latitude E6420 laptop with Ubuntu 12.04 alongside Windows 7 (dual-boot) docked in a docking station with 2 DVI outputs. It took me a week of tinkering to get the dual external monitors to work in Ubuntu, and I had to disabled the "Optimus" feature in the BIOS. But now neither external monitor is detected in Windows, and the resolution is also very low. Do you know how I can successfully dual-boot Windows 7 and Ubuntu on this machine using my 2 external DVI monitors? I have an open question here too, trying to resolve this same issue: http://askubuntu.com/questions/146933/dock-with-dual-external-dvi-monitors-with-intel-nvidia-optimus

• Poor CPU usage under Ubuntu

  - by remek

  Hello, I just upgraded from Ubuntu 9.10 to Ubuntu 10.04 and I am now experiencing a strange problem. My computer has a quad-core processor, and when I am running several processes simultaneously, none of the cores is fully used. Before the upgrade, when I was running 4 processes, each of them was using 100% CPU (I could see that with the 'top' command). But now, CPU usage oscillates and is always pretty low. Has anybody an idea about this problem? Is it due to Ubuntu or to the program I am running? Thank you very much in advance for your help! Best, remek

• Unusable Source for Ubuntu image on Xen 3

  - by Roberto Aloi

  Hi all, I'm trying to create a new VM in Xen 3, running Ubuntu 10.4 (32 bit) as the guest OS. Xen 3 is installed on a machine running OpenSuse 11.2. I downloaded the Ubuntu image from the ubuntu.com website and I mounted it on /dev/loop0. When I try to create the new VM in Xen with the given source, Xen complains the "source is unusable". I've also checked the md5 sum for the image. It's fine. Any suggestion or hint that could help me?

• Ubuntu 11.04 hangs at "checking battery state" while booting

  - by MisterSir

  When I try to boot Ubuntu 11.04, it just hangs when it gets to checking battery state. I know this issue is usually related to graphic drivers, but it worked like a charm for months now. Last time I was on Ubuntu I updated my system with the update manager, so maybe an update caused it. Anyway, I really need Ubuntu. I'm in the middle of work on a website and I have a deadline, so I need some help over here. Thanks. p.s. I tried reinstalling gnome-power-manager. Didn't work. And I'm not on a laptop.

• Ubuntu 9.10 freezes when HDMI port is connected

  - by Felipe Hummel

  Hi, I have a Sony Vaio FW350 with a HDMI output. I'm trying to use it under Ubuntu 9.10 with a LG LCD monitor 21,5'. I've tried two approaches: Boot the laptop with the HDMI cable connected and monitor turned on. Result: LCD Monitor keeps turned on but the whole screen is black and Ubuntu do not seem to be initializing. Boot Ubuntu until the end. I then connect the HDMI cable into the Laptop. The mouse and the whole system freezes. In both cases the only way to turn off the laptop is holding the power button. I've looked around the internet for similar problems, but only found workarounds for the same problem with VGA input, not HDMI. I also tried to use metacity before connecting the cable, but still got the same result. Any hints?

• Ubuntu Volume overriding settings set in Alsamixer

  - by Hayek

  Problem: How do I "lock in" the volume I set through alsamixer? I'm running Ubuntu 9.10. I adjusted the bass/treble columns in alsamixer but changing the system volume resets them all back to 100% I did save the settings by running alsactl store but everything is reset once I touch Ubuntu's volume icon in the top menu bar. This is rather painful because the computer is hooked up to a 650watt system with a massive subwoofer. As much as I enjoy my music, there's no need to have the walls vibrate :) What can I do to prevent Ubuntu from overriding the settings?

• How to change the terminal to SCO compliant in Ubuntu

  - by kaushik

  I have a server in which SCO 5.x is installed. I have several thin clients which were supplied from our head office. Those thin clients have linux pre-installed in them. When we tried to connect to our SCO server, we have found out that the thin client does not support SCO terminal type. So the program (Which is written in Oracle forms) is not working correctly. Lots of function keys stopped working and screen also not getting refreshed correctly. Hence we decided to use Ubuntu Live USB keys in thin clients. Now the problem is how can we change the terminal type to SCO in ubuntu ? Means I want it in the text terminal (Alt+Ctrl+F1,F2...) (Not in xterm...graphical terminal emulators). Does ubuntu support SCO terminal type ?

• Can't install Ubuntu 12 into VirtualBox (USB not recognized, ISO would not boot)

  - by wvxvw

  I'm trying out VirtualBox 4.18 and wanted to install Ubuntu 12 as a test. After installing VirtualBox (on Debian squeeze/sid), creating a virtual machine for Ubuntu and pointing it in Settings Storage IDE Controllers to the ISO with the proper version of Ubuntu, checked the "Live CD" option. Tried to define the IDE as master / slave, primary / secondary - all to no effect, and trying to boot this system, I'm getting to the screen which says: FATAL: could not read from the boot medium! System halted I've copied the same ISO to the USB stick, and I can boot from the USB (outside VirtualBox). I've looked at couple of tutorials / walk-through, there's nothing I can see that I would've done wrong. So, how would I configure it to boot from the desired ISO? Below is the snapshot with the current settings (sorry, I don't know how to get them as text).

• Centos OS resource footprint vs Ubuntu package refresh

  - by webworm

  I am trying to determine which distro to sink my teeth into. I am new to the Linux world and would like to choose a distro to focus on. I have read that CentOS uses less resources than Ubuntu, which is an issue for me since I am renting a VPS and resource cost is an issue. I have also read that Ubuntu has more up-to-date packages which is a concern for me as I want to use PHP and some packages that have a fair amount of dependencies. I am not using Linux as a desktop OS, rather just as a server for Apache, PHP, PERL, and Java development. What would be the best choice for a server OS? CentOS or Ubuntu? Are the resource requirements that different? Are the packages that different between the two? Thanks.

• Ubuntu (desktop) server needed for school

  - by Dave Moody

  I need to build an ubuntu server for school, but I hate with a passion command line interfaces. I need a server with a desktop, like the current win server 2003 (which has crashed, ugh). This server needs to host the school lan domain, have an active directory, and handle the roaming profiles that the students and staff access through WinXP workstations. It also needs to work as a file server, maybe a print server. Can anyone advise me on how to create an Ubuntu server starting with Ubuntu Desktop edition? Much thanks if you respond... Dave.

• Share files - Ubuntu 12.4 and Windows 7 - one network - password not accepted

  - by gotqn

  I have three machines - two with windows 7 and one with Ubuntu 12.4 version. There are in the same network connected by modem. The two machines shares file with no problem, but they can not see the machine with Ubuntu. On the other hand, I am able to see the share files of the windows machines from the Ubuntu's Network. When I select a folder, it wants the network password - I changed it several times in order to be sure that I am entering the correct one but in every case it says that the password is wrong. I have read some topics about files sharing between Linux and windows in which it is said that I should use samba, but is there a more easy way to do this, using the build it options?

• How to create launch icons on Ubuntu Desktop?

  - by MattSlay

  I installed Ubuntu in a VM using VirtualBox, and after a few hours of Googling all the things I had to install and configure for the rest of the environment, I am finally up and running with a Ruby on Rails IDE and have MySql up and running. After I start up the Ubuntu VM, I have to go to a terminal window and do this to start MySql: /etc/init.d/mysql start So that works fine, but, since I am such a GUI person, I’m wondering how I can create an icon on the Ubuntu Desktop that I can click on to launch this command. Can you tell me how to do that?

• How to install stuff on Ubuntu

  - by Industrial

  Hi everyone, I have just launched my first EC2 instance and choosed a Ubuntu image to start from, since it's quite well documented. However, I am trying to install the Redis package: http://packages.ubuntu.com/lucid/redis-server Maybe I am not googling properly or just stupid since the weekend is approaching, but I'll keep getting errors: root@ip-10-229-123-199:~# sudo apt-get install redis-server Reading package lists... Done Building dependency tree... Done E: Couldn't find package redis-server I'll assume that I need to add a repository or something to Ubuntu to help it find the package I want, but how do I do it? I can only find graphical guides which doesnt help me too much since I am using SSH. Thanks alot!

• Installed Ubuntu on usb drive, now it's read-only and can't be formatted

  - by weiszam

  I installed Ubuntu (ubuntu-13.04-desktop-amd64) on a 8 gb pendrive. Because it worked pretty slow, I wanted to change it back to a normal pendrive. But this is what happened. Windows7 can't open the usb drive, can't view files or anything, can't access attributes. When I select to format, it says it can't format it because it is write-protected. Tried the same running from an Ubuntu, and trying from a booted GParted thing. When I view the partitions, they can't be deleted either. What should I do to get it formatted?

• sudo like in Ubuntu (for Debian and other Linuxes)

  - by chris_l

  Hi, I personally like the default sudo behavior of Ubuntu: - Root login impossible - "admin" group granted "ALL=(ALL) ALL" - users in the "admin" group are asked for their user password (not a root password) when using sudo. [I like it, because this way, there's no root password to be shared among several people. There may be good reasons for other opinions, too - but that shouldn't be the topic of this question.] Now I'm trying to re-create this behavior in Debian Etch. It basically works, but there's one important difference: Debian doesn't ask for a password. It should ask for the user's password. I edited the sudoers file to be exactly the same as in Ubuntu, and I added a user to the newly created "admin" group. What else do I have to do to get the Ubuntu behavior in Debian (and other Linuxes)? Thanks Chris
