• cannot make ubuntu 64-bit v12.04 install work

  - by honestann

  I decided it was time to update my ubuntu (single boot) computer from 64-bit v10.04 to 64-bit v12.04. Unfortunately, for some reason (or reasons) I just can't make it work. Note that I am attempting a fresh install of 64-bit v12.04 onto a new 3TB hard disk, not an upgrade of the 1TB hard disk that contains my working 64-bit v10.04 installation. To perform the attempted install of v12.04 I unplug the SATA cable from the 1TB drive and plug it into the 3TB drive (to avoid risking damage to my working v10.04 installation). I downloaded the ubuntu 64-bit v12.04 install DVD ISO file (~1.6 GB) from the ubuntu releases webpage and burned it onto a DVD. I have downloaded the DVD ISO file 3 times and burned 3 of these installation DVDs (twice with v10.04 and once with my winxp64 system), but none of them work. I run the "check disk" on the DVDs at the beginning of the installation process to assure the DVD is valid. When installation completes and the system boots the 3TB drive, it reports "unknown filesystem". After installation on the 250GB drives, the system boots up fine. During every install I plug the same SATA cable (sda) into only one disk drive (the 3TB or one of the 250GB drives) and leave the other disk drives unconnected (for simplicity). It is my understanding that 64-bit ubuntu (and 64-bit linux in general) has no problem with 3TB disk drives. In the BIOS I have tried having EFI set to "enabled" and "auto" with no apparent difference (no success). I never bothered setting the BIOS to "non-EFI". I have tried partitioning the drive in a few ways to see if that makes a difference, but so far it has not mattered. Typically I manually create partitions something like this: 8GB /boot ext4 8GB swap 3TB / ext4 But I've also tried the following, just in case it matters: 8GB boot efi 8GB swap 8GB /boot ext4 3TB / ext4 Note: In the partition dialog I specify bootup on the same drive I am partitioning and installing ubuntu v12.04 onto. It is a VERY DANGEROUS FACT that the default for this always comes up with the wrong drive (some other drive, generally the external drive). Unless I'm stupid or misunderstanding something, this is very wrong and very dangerous default behavior. Note: If I connect the SATA cable to the 1TB drive that has been my ubuntu 64-bit v10.04 system drive for the past 2 years, it boots up and runs fine. I guess there must be a log file somewhere, and maybe it gives some hints as to what the problem is. I should be able to boot off the 1TB drive with the 3TB drive connected as a secondary (non-boot) drive and get the log file, assuming there is one and someone tells me the name (and where to find it if the name is very generic). After installation on the 3TB drive completes and the system reboots, the following prints out on a black screen: Loading Operating System ... Boot from CD/DVD : Boot from CD/DVD : error: unknown filesystem grub rescue> Note: I have two DVD burners in the system, hence the duplicate line above. Note: I install and boot 64-bit ubuntu v12.04 on both of my 250GB in this same system, but still cannot make the 3TB drive boot. Sigh. Any ideas? ========== motherboard == gigabyte 990FXA-UD7 CPU == AMD FX-8150 8-core bulldozer @ 3.6 GHz RAM == 8GB of DDR3 in 2 sticks (matched pair) HDD == seagate 3TB SATA3 @ 7200 rpm (new install 64-bit v12.04 FAILS) HDD == seagate 1TB SATA3 @ 7200 rpm (64-bit v10.04 WORKS for two years) HDD == seagate 250GB SATA2 @ 7200 rpm (new install 64-bit v12.04 WORKS) HDD == seagate 250GB SATA2 @ 7200 rpm (new install 64-bit v12.04 WORKS) GPU == nvidia GTX-285 ??? == no overclocking or other funky business USB == external seagate 2TB HDD for making backups DVD == one bluray burner (SATA) DVD == one DVD burner (SATA) 64-bit ubuntu v10.04 has booted and run fine on the seagate 1TB drive for 2 years.

• Ubuntu keyboard shortcuts - two-part question

  - by Don

  Background: I come from a Windows background and just started dual-booting Ubuntu (my first Linux experience) about 4 days ago. So my systems are Windows 7/Ubuntu 12.04, and so far I'm loving Ubuntu. I am a dedicated mouse-abolitionist (trackpads are hell) and do most of my browsing and navigation with keyboard shortcuts. However, on switching to Ubuntu, a lot of my keyboard shortcuts are gone, and my productivity has resultantly taken a huge hit anytime I am using Ubuntu. Problem 1: My computer was designed to display on-screen notifications for a second when I hit caps-lock or num-lock, and there are no constant indicators of the lock status (LEDs, etc). In Ubuntu, the keys still worked, but the notifications were gone. Googling got me a tutorial on key-binding(Compiz) and scripts, so now I have capslock and numlock running this script: #!/bin/bash icon="/usr/share/icons/gnome/scalable/devices/keyboard.svg" case $1 in 'scrl') mask=3 key="Scroll" ;; 'num') mask=2 key="Num" ;; 'caps') mask=1 key="Caps" ;; esac value=$(xset q | grep "LED mask" | sed -r "s/.*LED mask:\s+[0-9a-fA-F]+([0-9a-fA-F]).*/\1/") if [ $(( 0x$value & 0x$mask )) == $mask ] then output="$key Lock" output2="On" else output="$key Lock" output2="Off" fi notify-send -i $icon "$output" "$output2" -t 1000 But, whether turning it off or on, the notifications always say that I have turned it on. Is there an easy fix for this, or an easier way to work it to get it do display the CORRECT notifications? Problem 2: I'm not sure if this is because of my keyboard or Ubuntu. In Windows, I use Chrome and use the ctrl+pgUp/pgDwn shortcuts quite a bit to switch between tabs. On my keyboard, I can enter pgUp and pgDwn by either disabling NumLock and hitting 9 or 3 respectively on the 10key. Alternately I can hold the fn key and hit up or down arrow. The first method is the one I very heavily relied upon, and it works in Firefox for Ubuntu, but not in Chrome nor in Chromium. The second method (ctrl + fn + up/down) works fine in Chrome. However, I'd dearly like to find a method to make the first method work. Any suggestions? Thanks in advance for your help. Update: @julien: I've checked the keyboard layout options - I didn't find anything that seemed useful for this goal. @Marty: The script runs once when the button is pressed. In Compiz, I've tied those two keys to the script, so when I press the button, it runs the script with the button pressed as a parameter. Update: @elmicha: Thanks. That one works a lot better, and it even pops an icon into the status bar when caps lock is on. There's still a very slight problem in that if I quickly tap the key twice, the image will show that it has been turned on and then turned off, and the notifaction will come and go from my status area, but the text of both notifications will be "Caps Lock on". Same with Num Lock. However, if the time between presses is long enough for the first notification to disappear, everything displays correctly. Given how quickly the notifications disappear, I don't expect this will pose too much of a problem for me.

• Starting an Erlang slave node in escript fails when using custom Erlang in Ubuntu 10.4

  - by Adam Lindberg

  I have the following escript: #!/usr/bin/env escript %%! -name [email protected] main(_) -> NodeName = test, Host = '127.0.0.1', Args = "", {ok, _Node} = slave:start_link(Host, NodeName, Args), io:format("Node started successfully!"). When running it on Ubuntu 10.04 I get this: $ ./start_slave Node started successfully! $ I want to install my own Erlang (latest version, debug compiled files for dialyzer etc) since the stock install of Erlang on Ubuntu lacks some features. I put my Erlang binaries inside ~/Applications/bin. Starting Erlang normally works, and starting slave nodes inside an Erlang shell works as well. However, now my escript doesn't work. After about 60 seconds it returns an error: $ ./start_slave escript: exception error: no match of right hand side value {error,timeout} Even if I change the first line to the escript to use my erlang version, it still does not work: #!/home/user/Applications/bin/escript The slave node is started with a call to erlang:open_port/2 which seems to be using sh which in turn does not read my .bashrc file that sets my custom PATH environment variable. The timeout seems to occur when slave:start_link/3 waits for the slave node to respond, which it never does. How can I roll my own installation of Erlang and start slave nodes inside escripts on Ubuntu 10.4?

• newly added files don't sync down

  - by poolie

  I added some files into my Ubuntu One/My Files folder on my desktop machine. I can see them in the U1 web ui. My laptop is connected to the same U1 account, and in the Ubuntu One preference pane I can see it's connected to the account. However, my new files never download. In syncdaemon.log I can see it checking a bunch of other existing files, and then the file ends with many repetitions of 2011-01-04 11:05:42,277 - ubuntuone.SyncDaemon.Main - NOTE - ---- MARK (state: <State: 'READY' (queues WORKING_ON_METADATA connection 'Not User With Network')>; queues: metadata: 1; content: 0; hash: 0, fsm-cache: hit=5086 miss=69) ---- I do have a working network connection. What do I do now?

• Can't reboot netbook with any of the reboot parameters

  - by Delan Azabani

  I have a Sony VPCW218AG netbook that I've dual-booted with Ubuntu 10.10. Unlike the preinstalled Windows 7, Ubuntu will not reboot on this computer. Rebooting from Gnome, using the reboot command and SysRq+REISUB all don't work; they end hanging with a blank screen. I have read that Atom netbooks don't have a keyboard controller and therefore the default reboot method, kbd, won't work. I have actually tried all ten reboot= parameters listed here; none of them work. I have also tried disabling ACPI with noacpi acpi=off for each one; that didn't help either. Are there any other things I can try to fix the rebooting problem?

• Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

  - by Madiyaan Damha

  I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,

• Generalize, or Fix The Problem?

  - by Droogans

  Which of these two programmers is "better", from a managerial standpoint? The first programmer is Albert. You tell Al to make a system that will pass you the salt at the dinner table. He does it in less than a day. It works fine. The second programmer is Ben. Ben is told to make a program to pass the salt, and after two days, he's still working on it. It will save time in the long run...if you need pepper, ketchup, etc. There isn't any clear indication that there will be a need for this, but it's not improbable. Who's the better programmer to have working under you, as a manager?

• KVM CLI install for CentOS 6.3 defaults to Minimal Install

  - by i.h4d35

  So I now I've installed KVM (and its associated tools and packages- libvirt, VMM etc.). On the GUI (i.e using the VMM), installation works as its supposed to. However, when I try to create a VM using the command line interface, the OS (I am working with CentOS 6.3) defaults to a Minimal Install instead of giving me options to choose from at the time of installation. I am trying to install using the following command: virt-install \ --connect qemu:///system \ --virt-type kvm --name testVM2 \ --ram 512 --disk path=/var/lib/libvirt/images/testVM2.img,size=8 --vnc \ --cdrom /media/db18de8e-0853-49fb-80de-5c794d58a46f/CentOS-6.3- x86_64-bin-DVD1.iso \ --network network=default Specifying the OS-type or the OS-variant parameters doesn't make a difference. Is there something that I am missing out on or some other parameter that I must specify? Thanks in advance.

• Disk utility running for a long time

  - by Nik

  I had a spare, old external usb hard disk which stopped working long time back due to improper removal of disk. I tried fixing it in windows (when I did not have ubuntu yet), however I couldn't fix it. So I tried formatting the disk and creating a new partition using the disk utility in ubuntu. However it seems to keep running without any indication of the progress or whatsoever. I have no idea what is happening. I have attached a screenshot below to show what I mean. As you can from the screenshot above it seems to be working on it but no indication on the progress or what it is doing. Any attempt to exit it or do any other task like safe removal or format partition leads to the the following dialog box. What should I do? Wait or restart the computer..???

• Installing on a Lenovo S10-3

  - by Søren Hauberg

  I'm trying to install Ubuntu 10.10 netbook edition on my Lenovo S10-3. According to the release notes, there is a bug in the kernel that forces me to add intel_idle.max_cstate=0 to the kernel parameters. I did this when booting the install CD and I was able to install Ubuntu. During the installation I chose to fetch updates from the net. Now when I try to boot the machine it just hangs. I have tried booting the machine as-is and I have tried adding the above-mentioned kernel parameters. Same experience. So, my questions is how do I install 10.10 in this machine and how do I boot it after I've installed the OS?

• Which, among the humble indie bundle V games, work on 10.04?

  - by daithib8

  Inevitably, I've coughed up for the latest Humble Bundle, containing 5 games: Amnesia, Bastion, Limbo, Psychonauts and Superbrothers: Sword and Sorcery. At the download page it says download for ubuntu but after that it transpired (after much head scratching) that the three games it lists "are not available for your version of ubuntu". The other two, Bastion and Psychonauts "will appear on the page soon", but until then does anybody think they might work? I don't want to to be disappointed after downloading a 4gb file, causing me to reminisce on childhood memories of loading 8-bit tape games for 45 minutes only to find out that you had to reload them once you died after 30 seconds in.

• Kinetic Scroll in Maverick

  - by Shoaib

  I have Sony VAIO FW 230J laptop. I was using Lucid and upgraded my system to Maverick beta in September 2010. Although there were few issues with beta release on my system although I did not felt myself in any deadlock. The most notable experience on my ubuntu was the smooth and kinetic scrolling and very sensitive touch pad experience with finer control that was oddly normal in previous releases and even on windows 7 currently. Definitely this release of ubuntu is improved for touch UI experience. I believe that this is magic of 10.10. For my official system I waited until the final release was out. After installing (upgrading) official system to Maverick I am not feeling the same smooth and kinetic scroll experience. My laptop has Graphics: Intel DMA-X4500MHD while my official desktop has Graphics: Intel DMA-X4500HD Do I need to install or update some software package to have similar kinetic scroll experience?

• Should a programmer "think" for the client?

  - by P.Brian.Mackey

  I have gotten to the point where I hate requirements gathering. Customer's are too vague for their own good. In an agile environment, where we can show the client a piece of work to completion it's not too bad as we can make small regular corrections/updates to functionality. In a "waterfall" type in environment (requirements first, nearly complete product next) things can get ugly. This kind of environment has led me to constantly question requirements. E.G. Customer wants "automatically convert input to the number 1" (referring to a Qty in an order). But what they don't think about is that "input" could be a simple type-o. An "x" in a textbox could be a "woops" not I want 1 of those "toothpaste" products. But, there's so much in the air with requirements that I could stand and correct for hours on end smashing out what they want. This just isn't healthy. Working for a corporation, I could try to adjust the culture to fit the agile model that would help us (no small job, above my pay grade). Or, sweep ugly details under the rug and hope for the best. Maybe my customer is trying to get too close to the code? How does one handle the problem of "thinking for the client" without pissing them off with too many questions?

• Unity does not display properly [closed]

  Ubuntu Unity on the Ubuntu netbook edition installs without a problem but when I log in though, where the panels are, there is just blank area with a shadow effect style thing on it. I can open apps but the Window buttons and the global menu are not visable. Does this mean that I cannot use Unity. I'm running it through Wubi on a Dell Inspiron 1501 laptop. My total ammount of graphics memory is 831MB My dedicated memory is 128MB. The odd thing is is that Windows Aero displays without a problem so why is there a problem with Unity Hope this helps Ben

• When syncing, removed contacts still show upp (One contacts)

  - by Niklas

  Hi! I just tried out using the Ubuntu One Contacts app for android. First I imported all the contacts from my phone, SIM-card and Google mail account, then I spent quite a while removing duplicates which got imported. Then I tried to sync it for the first time. The strange thing is that I also got all the contacts which I removed from my contacts list on the website. So I have to set "show only contacts with phone numbers" to get all the email adresses I imported from google ealier to not show up, even though I deleted them from the contacts list and have only Ubuntu One contacts showing. Why is that? Thank you!

• How do I set up multi seat?

  - by JJ Mcfly

  Hi I was hoping to have a 2 seat setup. One will be for my TV just going to run Boxee. The other is for my main Desktop. I've been looking for a good guide to help me navigate this, I'd like to use ubuntu 10.10. I am assuming it's just a case of getting a box + 2 graphics adaptors and 2 usb mice and keyboards, one of which will be bluetooth for the TV. I can't seem to find much documentation on this idea. Can anyone point me in the right direction? Also I am assuming that this is all possible with a standard ubuntu install, but with some additional configuration. Thank you in advance for any advice you can offer me JJ Mcfly

• Minimal Lunix distribution with sshd and apt

  - by Sergey Mikhanov

  When I signed up for my Debian Linux VPS hosting and first logged on and invoked ps, there was the only user process running: sshd. As I can see, this was minimal Linux with only two things installed and configured: sshd and apt (plus all dependencies, of course). I want to build (or use existing) similar Linux distro, any advice on how to build (or pick) one? Googling "minimum linux", or "linux with sshd only" usually brings up Debian's netinstall, which is not what I want. Thanks in advance.

• Need help running Python app as service in Ubuntu with Upstart

  - by GreeenGuru

  I have written a logging application in Python that is meant to start at boot, but I've been unable to start the app with Ubuntu's Upstart init daemon. When run from the terminal with sudo /usr/local/greeenlog/main.pyw, the application works perfectly. Here is what I've tried for the Upstart job: /etc/init/greeenlog.conf # greeenlog description "I log stuff." start on startup stop on shutdown script exec /usr/local/greeenlog/main.pyw end script My application starts one child thread, in case that is important. I've tried the job with the expect fork stanza without any change in the results. I've also tried this with sudo and without the script statements (just a lone exec statement). In all cases, after boot, running status greeenlog returns greeenlog stop/waiting and running start greeenlog returns: start: Rejected send message, 1 matched rules; type="method_call", sender=":1.61" (uid=1000 pid=2496 comm="start) interface="com.ubuntu.Upstart0_6.Job" member="Start" error name="(unset)" requested_reply=0 destination="com.ubuntu.Upstart" (uid=0 pid=1 comm="/sbin/init")) Can anyone see what I'm doing wrong?

• Why can't i ping server? VMware set to 'Bridged' loses IP address on 10.04.

  - by Dave

  I have installed a fresh 10.04 server onto a laptop on a home network as a VMware machine and set network connection to 'Bridged: connect directly to the physical network' from within VMware and rebooted the server. It then loses its IP address. 'dhclient eth0' says "No working leases in persistent database - sleeping" DHCP is working fine on the wi-fi router. The laptop is wired to a wireless router and from there wirelessly to a desktop. Desktop and Laptop can ping each other from Windows. I can ping the VM from Windows on the same laptop, but not from the desktop. Strangely ping has started to resolve hostnames to IPv6 addresses and not IPv4. Don't know whether that's connected? A kick in the right direction would be greatly appreciated. I've been an Ubuntu desktkop user for a few years, but new to ubuntu servers.
