Ubuntu Installation :: 10.10 - Unable To Login On Restart
Nov 6, 2010
I am using windows since I first get my pc but itz day-2-day demands and vulnerabilities make to turn to linux but for some other things I do need window yet last time kubuntu was on my machine along with window 7 (through wubi) but then I uninstall that kubuntu, coz I want to use ubunto. I've got my ubuntu 10.10 cd, so I just sat infront of my pc, inserted the disc and it was a happy installation as it usually does with wubi but when I restart my pc and go for ubuntu OS , there show up a kubuntu screen, which has a title like ubuntu login and there in username field, that's not my username dat I've choose for my ubuntu but it is my pc-name from win7. Well I try to log-in with the user I'd made during installation but it didnot let me logged-in I try again n again even through console but no hope. Then I go back to win and uninstall wubi and get install again ubuntu but nothing different was there to meet me. I have a core 2 Quad Q6600 2.40 Ghz intel processor with 64-bit win 7 ultimate. I am installing 32 bit ver of ubuntu 10.10...!

I upgraded Ubuntu to 9.10 and tried to log in, it worked that is until it freezes up and the only way out is to hit the restart button.
Note: I CAN log in with Failsafe Gnome.

I am using Ubuntu 10.04 on a dual-boot system with Windows 7. Yesterday I upgraded from 2.6.32-23 to 2.6.32-24. After that, pressing the shutdown button and selecting shutdown or restart (whether on the login page or after I've logged in) will only bring me back to the login page. I can shutdown or restart if I do sudo shutdown now, but I'd prefer to use the GUI. Also, there is no sound now (not a big deal, but still not good). And I can't access my storage partition (not the windows7 partition, but a third ntfs partition with data on it). I get the error message that I am unauthorized to mount. I have the only account on this computer, so I should be authorized. This one is a HUGE problem for me, because I need to be able to access my data for work. None of these were problems before the upgrade.
Oh yeah, and quickstart is not enabled. Also, if I go to Power Management, and try to alter what to do when Power Button is pressed, my only option is Ask Me. I know these have been problems/solutions to the shutdown/restart problem in the past.

I have just finished the upgrade of the latest version and I'm at the point of my system restating.
My system automatically tried to restart but on the restart I got the 'terminal' view. It stopped when asking for my username (it never normally asks for this before the grub menu) and then password. I didn't get any further than that.
I now have on my screen (still in the terminal view before the grub menu)
"name@name-desktop:...$ "
I'm on my phone now so I don't actually have the symbol for before the dollar sign but your know what it is. The raised S on a 90 degree angle.

I've tried to test 10.04. One, by upgrading a working KK installation. The other, was a fresh install. Both were as VMWare virtual machines.Both installs had the same problem. The install/upgrade process goes smoothly. When the GUI logon screen appears & I click on the user name, I'm unable to type in the password box. Nothing appears. If I then click "continue", the result is "authentication failure".

I have a weird problem. When I restart/reboot, the computer restarts (I see the BIOS, Grub, etc., sequences) and goes right back into my desktop session - no login required. This is not the behavior I want.How can I make it reboot to the login screen?I'm running Ubuntu 10.10 Maverick

I have installed Ubuntu 11.04 32-bit on my new desktop. After installation all gone well.
The initial upgrades after fresh installation also ran well and I was able to reboot and use the system successfully.This was before three-days.Yesterday night I ran again the Update Manager and installed the available (4-5) updates and then I installed Sun-Java-JDK using Synaptic Package Manager using the packages from the canonical partners.
After installation was done I shut down the system and in the morning when
I restarted the system the login screen is coming up but on entering the login credentials a black screen with some text(unable to see the text) flashes and returns me back to login screen.I tried logging in with both normal and admin type users.But admin type user too encounters the same problem.
I have partitioned my 500GB into 5 partitions and there is sufficient data on each partition.
I assume fresh installation would fix it and the data on logical partitions would be intact but doing this re-installation would require me to install the updates again and do all the settings I did till now again.

I made a huge mistake. I was installing dtc-toaster in a Lenny box, and i accidentally closed the aptitude window. Then I opened another konsole (I have kde 3.5 installed), and I couldn't switch to root via "su" command. I can't remember the error message that i got, but it was something like "module not recognized".
Next i reboot the PC, and when I tried to login in tty1, system saids that root "is not a valid username". I had no better luck with other users.
As I'm not an experienced user, I really don't know where to begin. The good news are that starting in recovery mode seems to work.
I have no extra data by now, except that I ran fsck (from a System Rescue CD) on the lenny root partition, and it found no errors.

I'm running Ubuntu 10.04 (and, on another server, 10.10) and can't seem to figure out how to remove the Shutdown and Restart options from the menu on the bottom right of the login screen.
I've tried
Code: gksudo -u gdm dbus-launch gconf-editor and checking the /apps/gdm/simple-greeter/disable_restart_buttons, but it doesn't do anything even after a reboot. I've also tried the above command as root (without the "-u gdm").
I have also tried adding the following lines to /etc/gdm/custom.conf:
Code: RebootCommand= ShutdownCommand= These seem to have no effect either. Is this a Gnome bug, or am I doing something wrong?

I upgraded to fedora 10 using yum but i have a problem, the installation went fine and after rebooting i got a login screen. I typed in my user name and password and after a second it returns to the login screen. Im sure the username and password are correct. If i type in another password i get an error message. So how can i log in?
This is what i did to upgrade to Fc10:
Code:
Then i got an upgrade wizzard and selected Fedora 10 and than reboot.
In the grub menu only one kernel is present which is the Fc10 so couldn't use the old one.
I've tried to edit the kernel with single for single user that works gives me a command line but im just not experienced enough to figure out how i can use the command line to login.

I've installed F12 twice now. After completing the installation and getting all the updates via YumEx, my network trouble begin after a reboot. I am not able to login as root under gnome so I can't see the services panel.
Tried to reinstall 'NetworkManager' after the fact but of course I have no network connections so I may have made the problem worse. I hate to reinstall and repeat the same troubles over again as it consumes a lot of time. I don't know where to begin.

If I'm getting good at anything with Fedora, it would be making mistakes. I have Fedora 12 installed and it was running fine until I attempted to set the path in bashrc and cshrc for jdk. Now I am unable to login using the only user account I created at install. When I enter my password the login screens goes blank then my mouse pointer appears with the circling dashed loading symbol for a few secs and then brings me back to the login screen asking for my password again.

My system is Dell 4300S with 1.4 GHz Pentium processor, recently upgraded to 1 GB RAM,120 GB WDC1200JB hard drive Sony DRU-720A DVD/RW drive, ATT plugandshare wireless adapter with Atheros AR5001X chip, ATI Rage 128 Pro Ultra TF video card, and Actiontec V90, and 56KFlex modem (Agere System Venus). I attempted to use preupgrade to upgrade from Fedora 12 to 14 using wireless connection. It seems, that upgrade finished successfully, except I am not unable to get to a GDM login. I updated SElinux to selinux-policy-3.9.7-10 and selinux-policy-targeted-3.9.7-10, and touch /.autorelabel overnight, I was able to login using GDM once. And that is all. After I boot, after Ctrl+Alt+F4, I can login to terminal.

I downloaded Gentoo and burnt it on CD.I did boot the livecd and the system passed starting stage and it recognised my hardware. After that, there islivecd login prompt, and obviously I tried to use root and no password but it says login incorrect. This is what I did:
Code:
livecd login: root
Password: [hit enter here]

I use firefox3.6.x, and i play online video (sockwave flash) often, but while opening the page (often has swf), the whole X restart, and back to login window of gdm. The problem not accured everytime i open the page, but very often. I met this problem both in ubuntu 9.10 and 10.04, and also lubuntu 10.04. So, i fall back to use firefox 3.5.9, and evrything seems fine.

I recently powered up my netbook... Selected my user log in, entered my password, and after a couple seconds I briefly see what looks to be the console and am returned to the login splash screen... I can Ctrl+Alt+F2 to get to the console and log in... but that is as far as I can get. This is the case for Gnome, Remix, and Remix 2D.
I can sudo apt-get (update, upgrade, etc) as well. It is the right password because if I type in a wrong one it presents an authentication failure dialog box.
How can I fix my log in screen and get to my desktop? I am Currently running 10.04.... waiting to get 10.10

I'm having a minor inconvenient issue with Suse 11.2/KDE4.3.From a cold boot, and then the first login, the desktop and WM [Compiz-Emerald] loads ok, but the plasmoids/icons are not 'clickable', although I can use keyboard, Command Line and 'right click' menus ok.If I restart X, then log in again, everything is ok, and stays ok until the next cold boot.It's as if the plasma desktop is masked [if that makes sense?], but only on the first login, as if there is a boot sequence issue or something.

I just installed slackware on my pc. The installation went fine (I think). When I am trying to turn the computer on, I am asked to type the "host login". As I can remember I didn't write any username, or password. But as it seems, I have to type this in to login. I tried with "root", then this comes up "root@host:^#" if this is right, what should I type here to get further...

I have a workstation with Fedora 13. This workstation is used for very long remote processes. Recently it has been shutdown accidentally by a user and has caused the loss of some of these processes. As such, for precautionary reasons, I have decided to remove these options from all our workstations so that only the super user can initiate reboots or shutdowns.
In previous versions I was able to do this by using gdmsetup and unchecking the Show Action Menu option. This also added the SystemMenu=false flag under [greeter] in the /etc/gdm/custom.conf file. This was under RedHat EL5. However in Fedora 13 neither of these methods work. Gdmsetup no longer exists and adding that flag to the custom.conf file does not work. I rebooted after editting the file and the shutdown option still appears at login.

Have installed Ubuntu Lucid and I'm unable to restart the computer. Doesn't work using the power icon in the top right or using sudo reboot from the termial - I have to hit the reset button to get the computer going again. The problem is only related to restart - shutdown works as it should. When I try to reboot, the screen goes black aside from a narrow band of crimson on the far left of the screen; it freezes at that point. I've had a look through the var/log/messages and saw nothing that was an obvious problem, but then again it's not something I've ever had to look at before. Tried adding acpi=off as an option but that seemed to make no difference.
Not sure whether it's relevant, but specs are 3ghz Core 2 Duo; ATI 4850;4gb ram; Gigabyte motherboard with Intel p31 express chipset.

Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?

I installed 10.04 on my old Dell Inspiron 600m laptop. After using it for about an hour, I was suddenly had no option to shutdown or restart the system when logged in on the main and only account. The 'Shut Down' applet on my bar was greyed out and the shutdown option was missing from the system menu.
I removed the 'Shut Down" applet and was unable to re-add it afterwards (wasn't a selection when adding to panel). If I log off, selecting shutdown or restart from the login screen does nothing.
'Sudo shutdown now' will shut it down, though it won't power the system off; it just hangs on an all-white screen.
I saw other posts suggesting Open Office Quickstart was the culprit, though I am not running this.

I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?
This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.
