Ubuntu :: Eliminate Constant Password Logins?
Feb 19, 2011
Very often I have to leave my computer for a few minutes while in the process of downloading files, or just to get a cup of coffee, and when I come back, I have to re-enter my password to continue. This level of security is unnecessary since I am the only one here, and there is no danger of anyone ever messing with my PC. How can I eliminate these annoying login requests? One reason I am trying to get away form Windows is to have the computer do what I want, and not what other people think I want. I have been experimenting with various Linux OSs and several versions of Ubuntu, and this is an annoyance in every one I try.

I don't need password protection, I don't have it on Windows 7 for any acct, and also don't want it on linux.However, as a non-tech person, I couldn't eliminate this requirement.I tried inputting an easy password to minimize inconvenience but was warned it was either "too short" or "too simple".

I want to login into my main machine from my laptop,sing ssh with several linux consoles, all running mc.Is there any way to only login once with one password, and get several consoles running at the same time?It's a pain to have to ssh and give the same password for each console I want running on the main machine.I've looked at the screen package, but can't seem to get that working.What I'd really like is 3 different terminal sessions, all connected with one password. Each terminal with 3 tabs, all running mc under the same password. So that's 9 different instances of mc running remotely

I am new to CentOS, and am having a problem with authentication.The system accepts the login if the first 8 characters of the password are correct, regardless of the length of the password.My root password is 15 characters, but entering the first 8 my login is approved, which is a bit of a security concern.I think this may be something I am missing in the PAM configuration.I've experienced the behavior on SSH as well as Webmin.

I'd like to eliminate anything unnecessary from my Ubuntu Server box (on a Compact Flash IDE drive) and set it up to boot into RAM. I've seen ways of getting a live CD to do this and seen other distributions that are designed to do this, but since I'm familiar with Ubuntu, I'd like to be able to get rid of my swap space and make the existing installation boot to RAM.

How do I eliminate the "TrashPail icon", and the "Computer icon" off the desktop..? I likes and needs a clean desktop, to display pix-edits, so there isn't anything pulling away the focus from the pix... It's a bit of a nightmare having a pix of a garbage-pail in ones face when the artist is trying to focus on the fine quality of his artistry...

I have Radeon HD 3870, which is limited to 2D purposes I understand...
Will this mean that I cannot use DRI? Will it have a performance impact in 2D applications?
Does DRI make watching movies on PC 'better'? Especially 720p ones.

I don't know why its called "GRUB 2" while it is actually GRUB 1.98 or 1.99. Anyway.So here's the thing. Due to the fact that I am dual-booting Ubuntu + Windows XP, my GRUB menu would show up during boot with or without me holding down SHIFT. This takes several seconds. What I'd like to do is that GRUB does not show up at all during "normal" boot and only shows up when I hold down the SHIFT right after BIOS POST.

Whenever I login to a certain server using SSH I get a very long delay before a prompt appears. Everything I looked up on this issue says that it's a DNS issue and that I should disable reverse DNS lookups on the server.
But, the remote server is a shared webhosting server. I e-mailed the sysadmins but they say they have no DNS issue and that they won't change the server configuration. So, how can I fix this issue from my side (client side)? I have a static IP address and a hostname that points to it.

I have a Macbook running Ubuntu Karmic and I have been asked to DJ (amateur to the MAX) a friend's wedding next weekend. I don't have the coin to spend on a Mixer so I can run my mic and laptop through my amp so I figure I'd just run the Mic into the mic input on my Macbook and let the laptop do the mixing for me.Well, I added the loopback module to Pulse and inserted a command to have it auto start:
Code:
pactl load-module module-loopback

I use tcl-expect script to ssh to the server. How can I eliminate the first 2 lines if using system(./script.sh) to execute it, as the default output will be shown on shell and the first 2 lines are included.
Essentially I just want to have the "ps" result, not the login process. code...

Every time kubuntu updates its headers/boot image I get another version on disk in /boot. These also show up in menu choices when I boot. I currently have 7 or 8 versions and would like to get down to three or four.
In the past I just deleted the files of related versions from /boot but is this the preferred method? Is there a better/safer way to get rid of old kernels?

I have a file that contains a number of lines of DNA sequences like the single (yet very long) line below. There are far too many trailing and ending dashes then is needed in the file (however some are needed so I cant just delete all leading and trailing dashes).Therefore, I want to count the number of dashes leading up to the first base (either an A,C,T, or G) for every line in the file. I then want remove the smallest number of leading and trailing dashes among all the lines from each line in the file.So basically lets say the smallest number of trailing dashes between all lines in the file is 300 and the smallest number of leading dashes between all lines in the file is 500 dashes. I then want to subtract 500 dashes from the beginning of every line and 300 dashes from the end of every line. I hope this explanation is clear.

My laptop running ubuntu 9.10 load NEVER drops below 1, and generally hovers between 1 and 2. This does not happen on any other of my ubuntu machines.
Any ideas of what to check? I've turned off indexing and watched system monitor. I always sit at 0% cpu usage, no active apps, but always a high load.
Attached is a screenshot showing top (with the load).
In my system monitors up top you can see the middle one in red, which is load. Constantly 1-2. The left one is cpu (almost no usage at all) right right one is disk IO.

I'm on 10.04. 64bit (but dont think this is 64bit related)
I have been getting this very annoying error while trying to burn DVD-DL media from an iso using growisofs. Here is the command I used (to burn a backup copy of an xbox360 game)
Code:
growisofs -use-the-force-luke=dao -use-the-force-luke=break:1913760 -dvd-compat -speed=2.4 -Z /dev/scd0=nameofmyiso.iso
Now, every single time, usually around 50%, I get this error:
:-[ WRITE@LBA=aacf0h failed with SK=3h/WRITE ERROR]: Input/output error
write failed: Input/output error
I've been searching around and found threads with people complaining about this error since 2005, but not a single one of them presented any solution (some hint to a kernel issue, which I'd have no idea how to fix. I'm a noob at linux).
I also tried burning it using imgburn under wine, same error, also at 50%.
This is very frustrating, Ive burned around 6 coasters so far and DVD-DL are expensive to keep on this trial and error.
p.s It's not faulty media before anyone asks. I tried it on Mac and it worked fine. Also, this drive worked well before, before I migrated this machine.

I'm using Lucid on a laptop, (details in sig). Often after I've been running Ubuntu for a while, like a few hours, my HD activity light will come on and not stop, causing my machine to become laggy. (A link might open 3-5 seconds I click on it, typing appears a second after I press the key, a window or dropdown menu might take 5-10 seconds to be drawn.) I currently have Firefox with one tab and a Nautilus window open. Conky says the CPU is running at 10-20%, RAM is almost all used, (I assume Firefox's cache is filling up, since I've been surfing for a while), and swap is around 25% full. I just turned Compiz & Emerald off, but the HD is still spinning away. At this point, I usually log out and in again, or reboot. I though slowing performance with usage, resource-hogging background processes and constant rebooting were Windoze traits! What gives?Apparently, this is caused by Update Manager. Unbeknownst to me, Update Manager was waiting for me to give it the go-ahead, but while it's open, instead of patiently waiting, it renders my computer unusably slow, even though it's not supposed to be doing anything.

here's the videos video of the error in action
i just upgraded from 10.10 to 11.04 and am using the "classic" gnome 2 interface. i have an ati card, currently powered by the standard fglrx drivers. something must be wrong with compositing, because when i mouse over avant window navigator, indicators, menus, drag files, etc, there is a good (but still random) chance of it breaking my display.
just for the record, i have tried this with the newest catalyst drivers from the official website, the fglrx drivers from the repository and without any fglrx drivers at all. i am running a patched version of emerald that works with the included compiz, but i still get the same crashes with metacity's window decorator and without avant window navigator. indicator menus will just crash the screen from gnome-panel.
i had also gotten this same problem in a previous natty install using unity.
edit: hmm, disabling compiz seems to keep the crashes at bay, so i think this is a (major) compiz bug. does anyone know which logs i should include in my bug report?

My dads' hard drive went up a while back. So we got him a new one and installed Ubuntu 9.10 instead of windows. All was going well until About two weeks ago. The system restarts randomly. Not when anyone is doing anything in particular. Sometimes when we are using firefox, sometimes just sitting on the desktop, and never after any certain amount of time.Some times its after five minutes, some times after several hours. It's not a full out crash, the window for shutdown/switch user/restart comes up out of nowhere. When we close the window, it shows back up pretty quickly, but then the computer will just crash. While restarting, half of the time the computer won't make it past the bios screen before restarting again,and will continue the bios restarting cycle until the computer is unplugged. By the way, the system is a dell dimension E310 from 2005 with all of the original hardware minus hard drive inside, so if it is a hardware issue that wouldn't surprise me. Also, just one time after the restart I received the message "fsck from util-linux-ng 2.16" , if that helps at all.

I'm on a MacBook Pro 2,2 with Ubuntu 10.04. Multiple times Ubuntu freezes up and then crashes. I'm not entirely sure what is causing these crashes, but they happen mostly when I'm running anything graphics related, especially games. Although the crashes haven't been isolated to those instances. Any ideas on what could be causing this?

I recently wiped and partitioned my hard drive on my Sony Vaio Z series laptop. I set up the NTFS partition for windows, the Ext-4 partition for Ubuntu 10.04 Netbook Remix, and a large NTFS partition for my all my media. I installed the netbook remix off of a flash drive, and I couldn't have asked for a smoother install. Everything went fine, and I proceeding to install google chrome and all the other little goodies. After that, I configured all my settings and ran the update manager to get everything just fine. After a reboot, I became frustrated and prevented maximus from running on start up because I did not want every windows I opened to be maximized. After a reboot, the screen would flash very brightly more than once per second. I could see the top bar with the processes and such as well as the correct background, but I cannot do anything because the screen will not stop flashing. I figured out I could stop it from flashing by pressing ctrl+alt+F7, but the screen just freezes where it is at and is still unusable. Desperate to start enjoying my Ubuntu Netbook Remix, I wiped the Ubuntu partition and reinstalled and did everything EXACTLY the same except instead of preventing maximus from opening, I used gconf-editor to change the setting to not maximize everything by default. Reboot, exact same problem.
I've searched everywhere for a solution, but I only find people with vague similarities or explanations. Could it possibly be a graphics problem? My laptop has 2 graphics cards in it - an Intel integrated one and an nVidia one. The nVidia one has a hardware issue so I just use the Intel one for now. It is also worth noting that I have installed Ubuntu 10.04 (desktop) on my machine before and I never had any such problem.
Also, I tried booting up in the "safe mode" equivalent, but I eventually encounter a black screen and I am forced to hold down the power button to shut it down.
(also, if it's worth anything, I know how to use windows well if there's any way I can change something in Ubuntu from my windows installation)

I have installed Ubuntu 10.04 LTS on a flash drive and everytime I try to do an update I get the following error message:
Code:
Setting up linux-image-2.6.32-33-generic (2.6.32-33.72) ...
Running depmod.
update-initramfs: Generating /boot/initrd.img-2.6.32-33-generic
lzma: Encoder error: -2147467259
Failed to create initrd image.
[Code]...
also, I would like to know if I want to make clones of the flash drive, would a copy and paste suffice or do i need to use some cloning software? I have followed the instructions on ubuntu wiki to make my casper-rw larger than 4GB by making it an ext4 partition.
