Ubuntu :: Natty Hanging At Login If Network Not Plugged In
Jul 26, 2011
I have an acer one 522 netbook. I have installed Natty as a new install but if I don't have the network cable plugged in the system hangs at the login screen. This is prior to me having any input. Sometimes I can hit enter and get the password box but it freezes before I can input any information. Had a look at syslog and cant see anything wrong. Cant seem to find the messages log. why this would happen? If it continues and there is no solution I will install 10.04 instead

I'm running a fresh install of Lucid without any issues thus far. I have my computer setup to log me in automatically, without requesting a password.
I installed Gnome-do and set it up to run at login (as I always have). After a reboot, my system is not responding to input from my mouse or keyboard. I can move my cursor, but it will not accept input.
I see gnome-do, which is partially covered by the "Unlock keyring" dialog" (which always comes up, I think to unlock my wifi).

In the process of trying to make Ubunti authenticate with AD2008, I followed some instructions and edited files as follows:
# /etc/pam.d/common-account
account sufficient pam_winbind.so
account required pam_unix.so
# /etc/pam.d/common-auth
[Code]....
After doing this I can no longer log in, it just hangs on the brown screen after logging in... it also asks me for my password twice before authenticating?

Acer 5250-BZ475 laptop, fresh install of Ubuntu 11.04. Boots up beautifully as long as an ethernet cable is plugged in. Otherwise, I get to the login screen and have just enough time to start typing in my password before the entire system hangs hard - no mouse, no keyboard, can't even get to a terminal, nothing. Have to hard power off the machine.
It seems to be a problem with the wireless card trying to initialize, but there doesn't seem to be a bios option to disable wireless on this laptop, so I'm a bit at a loss as to how to fix this problem. By the way, wireless works fine if I boot up with a cable connected - I can see all the wireless access points in my area no problem. I just can't boot without a wired connection, which makes my laptop more or less useless when I'm away from home with it.

We are experiencing a rather odd issue with SSH access to our opensuse linux server. When accessing it via SSH on the local network everything works fine and there are no issues. However, when accessing it via SSH from an external location it hangs randomly. We can log in without issue and some commands seem to work ok. If we attempt to run a command such as "top" the SSH session simply hangs permanently. using "strace" the process hangs at different points so it is not a particular part of it's execution that appears to be the problem.

Alright, every time I boot or shutdown my routing box, it hangs at configuring and deconfiguring network interfaces. Below is my interfaces file. I see no errors or warnings in my log and I am running a pure kernel, not tainted with proprietary drivers. All of my hardware is 100% supported.

I have a kubuntu 10.04 box and it runs virtualbox with windows 2000. For the most part, the network cable will be plugged in and i should be able to rdp into my windows 2000 install just fine, however, for testing purposes and for backup server testing, I will not have the cable plugged in all of the time.How would I rdp into that windows 2k install on the same machine if no cable is plugged into the ethernet port?I have both the kubuntu install and the windows 2k install setup with static ip's, but it is not working.

Is there a way to have linux connect to the network when the ethernet cable is plugged in? I'm using Gentoo Linux, and I haven't found the right setup for the conf/net that'll allow me to do that.

I have been encountering this problem, not only on 10.4, but on older versions too: I use a wifi router to connect my laptop to the Internet, but sometimes I need to connect directly to another computer to move some files over GLAN. But Ubuntu's Network manager doesn't allow me to configure the eth0 interface without specifying a gateway (no gateway = grey submit button), but when a gateway is specified, it always rewrites the default gw specified already by the active wifi connection and returns back after unplugging the eth cable.
Of course this can be solved by a few route commands, but this is unacceptable since it is needed to establish the cable connection without any further assistance from within and as well without replacing the default gw and thus breaking the Internet connection. Is there, please, any possibility how to prevent Network Manager from replacing these routes?

I just tried upgrading to the Natty beta. I am having a problem logging in now. When I boot up I get to the GDM login window and try to log in. Then I get an error message that says: Failed to load session "ubuntu" And then I click log out and it just states me back to the login screen. There is no menu to select sessions or anything on the login screen, just the shutdown menu and the clock.
--Edit-- I fixed part of the problem and I can access my sessions now. I can log in using GnomeShell, but any of the other options result in "failed to load session 'ubuntu'" or "failed to load session 'gnome-classic'". I'm getting the feeling something is broken with Gnome, but I don't know what.

I just upgraded to Natty Beta 2, and when I tried to login, I was told that /tmp/2145539930/.kde/share/config/kdedrc is not writable (along with tmp/2145539930/.kde/share/config/knotifyrc is not writable). When I run ls -l, I get
Quote:
-rw------- 1 kdm nogroup 39 2011-04-16 19:55 kdedrc
I can dismiss the dialog box, and after a few seconds of delay, see a crash report that kdeinit4 seg faulted. I dismiss this and log in to see plasma not running, but I can Alt+F2 any command I wish (except plasma-desktop, it doesn't run). I already purged kdm and reinstalled, and I'm trying plasma-desktop now.

I thought before breaking my working PC, i thought id better ask the question.Is it possible to download a GDM log in theme and get it running on Natty? I've googled loads of possibilities, but got a feeling that as Natty is GDM2 it can't be done.I've downloaded Tweak and been able to change the log in wallpaper and the icon, but i want one of those fancy log in screens that ive seen on Gnome eyecandy.

I just did a fresh install of natty, installed a few programs along with the ati catalyst control center.
I am having serious login issues, here is what I do:
I am at the login screen right from start-up, type in username and passward and hit enter, screen goes blank, it appears I am logging in, ubuntu plays a sound and puts me back at the login screen. I do not get an "Authentication Failed" error like I would expect. Unable to login as myself or as root.
However, I am able to login if I select the "safe mode," I am not able to login under the normal mode or the ubuntu classic modes.
I suspect that this issue has to do with the ati proprietary drivers, after playing with the settings for a while in safe mode I am now able to login to the normal natty mode without any apparent issues.
Here is what I changed in ati catalyst control center to boot into natty mode:
I disabled the Xinerama and Tear Free options.
Under the 3D settings, I selected the "override application setting" for all the 3D settings I could.
I believe I still have some display issues as I am unable to drag windows from one display to another, my mouse is able to move just fine across displays though.
I also found that enabling Xinerama prevented me from logging into the ubuntu and ubuntu classic modes, but I was able to login to the ubuntu with no effects mode.

I just installed a test Natty VirtualBox server from the "mini" iso. After doing that the normal boot always ends with a blank screen and cannot login. The recovery boot option does work normally. After much digging around and various tests I found that the "splash quiet" boot options cause this issue.
I removed them from the /etc/defaults/grub file and ran update-grub. Next boot the login screen came up after as normal. It seems when the splash flashes that purple screen with the Ubuntu 11.04 message it is breaking something and does not get back out of some graphics mode.
This is in a VirtualBox window and I noticed that vesa framebuffers seem to be used by default in grub now. I never had this issue in previous releases and I'm just wondering if others have seen this and if there is a better fix than disabling splash. I don't mind having it disabled as this is a server install anyway and I'm fine with seeing debug messages during boot. If other have seen this then perhaps it needs to be logged as a bug?

i've installed ubuntu 11.04 on a friends Asus Eee pc 1005HA netbook. after the installation i tried to connect to the router using wireless, and when i enter the key, it fails to connect, so i tried using an Ethernet cable to connect but that doesn't work either,the network devices on the computer are:
Atheros AR8132 PCI-e fast ethernet controller
Atheros AR 9285 wireless network adapter
It lists the wireless device and the solutions to the problem, however, the solutions seem to be for Ubuntu 10.04 and also 10.10, and im not sure if it will work for 11.04 so far i have been unable to find out anything on the forums about the ethernet

I have two laptops, both with broadcom drivers and in both it's working pretty well with my university network but I can't find my home network on the list (I can see my neighbours network). It was working perfectly before the upgrade, and of course, I can connect on windows to my home network.

I upgraded to Natty at the beginning of May and Unity has been working fine until about 4 days ago. Around then, then I cold boot and log in, Ubuntu starts in "Ubuntu Classic" desktop. If I log out then back in, Unity starts as expected.In both cases of my logging in, Ubuntu Classic is not selected - Ubuntu is, which should start the UI under Unity.

I installed natty finally on my laptop (T410 Lenovo) via an upgrade from maverick. I tested maverick thoroughly first, since I had to perform the upgrade over the network, due to issues with natty booting from DVD. The upgrade went fine to natty, the system came up and I was able to get on locally and install other packages, though I did notice from time to time a lag in network performance. I installed VNC server and started it, as well as other network related services. However, I am noticing a definite issue with the network support and I suspect the natty kernel. The configuration looks sound, ifconfig, netstat and other functions appear to display the correct information, at least what I had with maverick (which worked).
Has anyone else seen issues with natty and networking? The glass looks okay, though I am using xfce and frankly there is nothing new there to really force me to upgrade, its just that this is a new LT and if I can cold install natty right now, it will save me an upgrade later.
System configuration (lshw) is below, ipaddress removed to protect the guilty..:
description: Notebook
product: 2522AP1 ()
vendor: LENOVO
version: ThinkPad T410
serial: R8M9B2Z

I have a wireless network (192.168.1.0) that's bridged to the Internet and a wired one (192.168.0.0) that's only local. When I am connected to both networks, Natty wants to route my Internet traffic through the wired, local-only one.
Can I make it automatically "just work", so that the right network is chosen for Internet traffic? Otherwise, what's the workaround?

I'm new to networks and servers, been using Linux on the desktop for a while now but always relied on the company's IT guy for setting up everyting LAN-based.
Now I want to build up my home LAN, and want to do it with Linux. I've managed to set up LAMP and file share servers.
What I am looking for is information on what I need, and how to set up a server for the following tasks:Centralized Username and Password, that when the user logs into any one of the desktops in the LAN, it uses this for authentication
Something that allows this authentication to be utilized in other servers (file access, web access, router logging, etc.). Something to make it easier for continuing permissions from one service to another. e.g. I have IPCop filtering content, and it has provisions for tracking who is making which request if there is authentication going on. (optionally) to run a script for mounting Samba shares or mapped network drives so from one system to the next. For example, in whatever box somebody logs in, it mounts a server share ("smb://Myserver/users/<username>") to a local folder ("my_user_share").
So;user "fred" ="smb://Myserver/users/fred" and user "wilma" = "smb://Myserver/users/wilma" but both would find their respective one mounted under "~/my_user_share". This would be irrespective of which box they are loggin in with. If the server share location changes (new server/servername), I change it on the server so the next time they log in it points to the right place.
I guess it is similar to Window's Active Directory, though I'm not sure what it's called, how to configure it and what it is and is not capable of doing.

I have found this link "Login Failed" message when logging in through RDP
I am suffering from exactly these symptoms. Can anyone suggest what the likely cause is? How would that bug/solution relate to my environment: openSUSE 11.3/xrdp 0.4.1-85.1?
And lastly, how can I find out if the update implied under "Additional Information" has happened?

I've tried Ubuntu, Arch, and most recently Fedora but the SUSE GNOME environment blows everything else away!
The only problem (so far) is that Network Manager requires you to enter your password every time you login to unlock the password keyring. I want to disable this.
I think some distros disable the prompt by using the login password to unlock the keyring, but I use auto-login (if that makes a difference).

I was wondering if there was some "clean / easy / official" way to enable networking during boot up and before a user logs in, other than editing /etc/network/interfaces by hand? Could be useful when away and in need of rebooting and still be able to access the computer, etc. I wouldn't mind doing it by CLI but just wondering if there is a GUI / simpler solution.(On Ubuntu 10.04.1)

I need to be able to login to my brother's comp, which is in another place quite far away from mine, and help him install some softwares and get some settings done for him, as he's more a newbie than me, but has been only able to install ubuntu successfully. He has a broadband connection and I have one too. I have used ssh over Lan and have been successful in this regard. From my understanding of the manual page, i don't think I can use ssh over two different networks. Which similar command/package will work for me if I want to login to his comp and execute commands as easily as I can do using ssh for two computers on the same network.
