Fedora :: FC9: Forgot - Partition Doesn't Work - Can't Login At The LUKS Login After Grub Starts
Feb 15, 2010
My computer was working this morning and both hard drives were working fine, then all of a sudden for about two hours I was stuck with this "problem", then after fumbling and moving and stablizing things, then Windows works? See below for details. I've finally reinstalled both hard drives, but the one with the Linux partition doesn't work: it says nothing is discovered on the disk. I can't login at the LUKS login after grub starts, therefore I can't get into Linux, but Windows works?! I used to be able to go directly into Grub when the computer starts, I forgot how to do that but it doesn't matter. If you need details I'd be glad to provide them. I just wondered why Linux doesn't work, but Windows does. I have Linux & Windows on two different separate hard drives

Got myself in a bit of a squeeze here. I was messing around with the Xorg install on my Fedora 12 system. I ended up reinstalling it. Now my mouse and keyboard work fine in single user mode / terminal. But if I try and boot to X they dont work at the login screen. HAL and udev are booting. Ive done a udevadm monitor test in single user mode and its seeing the devices connect and disconnect. Ive also tried both USB and PS2 devices. Same issue. Ive tried playing with xorg.conf and generating it with Xorg -configure :1 I dont know to use to fix it. After banging my head against the wall for 20+ hours I decided it was time to ask for help. m just Lynxing around the web at the moment =X

I burned Fedora onto a disk, but when I turn on the system it just goes straight to the Windows XP login.
I thought it was something wrong with the disk or something like that, but when I pop in the disk on my Dad's laptop, the installation for Fedora runs perfectly.
Also, yes, I checked the order for booting and the CD drive comes before the hard drive.

I've tried to ssh in as the root user w/o a password (RSA keys) but I've had no luck as the root user. I've tried the exact same commands with Debian 5 and Centos 5.5, without a problem. Fedora 13 and 14 won't work! I can only log in w/o a password as a normal user, never as the root user! It always asks for the password if I try as root. I've even tried copying Debian's and Centos's sshd_config file and restarting sshd, but it still won't work.
Code:
mkdir ~/.ssh ~username/.ssh
chmod 0700 ~/.ssh ~username/.ssh
echo "ssh-rsa AAAAB............Jw8V03loeZ username@thehostname" > ~/.ssh/authorized_keys
[code]....

I just upgraded from 10.04 to 10.10 this morning and after the upgrade I can't log in via GDM. If I log in it seems to work and the screen goes black, but then it goes right back to the login screen.I can't figure out what is throwing the signal, but the interesting thing is that if I stop GDM and log in on the console, I can run startx and my session runs fine (I'm typing this message from firefox). Any ideas on how to determine what is throwing the signal? I tried poking around in /var/log but I can't find anything that seems relevant.

I just installed Fedora 13 on a new computer and the timed login for gnome does not work unless you manually select it. This surprised me as I upgraded a separate computer to Fedora 13 and the timed login feature still correctly functions and does not require user interaction.
Code:
[daemon]
TimedLoginEnable=true
TimedLogin=<username>
TimedLoginDelay=3
Adding the above to /etc/gdm/custom.conf only adds an Automatic Login option that you have to manually select and then the computer will login. I would deem this less than useful.
Code:
[daemon]
AutomaticLoginEnable=true
AutomaticLogin=<username>
I know you can substitute the timed login with the automatic login and it will instantly login, but this provides no option to select another user. I have been unable to find any information why this feature no longer works and wanted to know if there is a new way or if anyone knows why the timed login feature was crippled.

I just added "export PATH=.:'printevn PATH'" to ~/.bashrc, then i can't use any commands, like "vim" or 'ls', it shows 'command not found'.
I cound't figure it out why. Then I logged out and tried to login. Another more serious problem occurred. after I type in login id and pass, it shows login seems to be right, but it doesn't login normally, but immediately bring me back to the login dialog box, and ask me to type log info again. I tried many times, it just constantly brought me back to the login page.

I was helping a friend of mine upgrade his system from 9.10 to 10.04. The upgrade went okay and he was able to use Lucid last night.
He has a dual boot with Windows 7, which was broken during the upgrade. I was able to help him fix that, using the instructions at [URL]
So the Grub issue is not the problem. However, after fixing his Grub install, he now cannot log into Ubuntu.
He selects the current kernel from the Grub menu, and the system starts up as expected. The splash screen that generally has the login box on it comes up - but no login box with user names and prompt for password never displays.
He can press CTRL-ALT-F2 and login from a terminal, but has no option to log into GDM.
I've gone through the usual dpkg-reconfigure gdm and had him reboot. Still no luck.

We use a linux (centOS I believe) cluster for our research. My professor somehow forgot the new password he set for root, and now can't login as 'su'. What is the way (or best way) to reset the root password without damaging something. I don't know whether it's even setup for 'sudo'. What will the procedure with and without 'sudo'?

I am new to ubuntu and I've installed it but I didn't use it too much. Now I was trying to login into ubuntu but I forgot the root password. Can I login into ubuntu or change the root password. I didn't make any other user than the installation were asking me. If I try to reinstall the ubuntu, the setup will help me to choose the same partition (to overwrite on the previous ubuntu)?

I am using 10.04 ubuntu and I have forgotten my password to login to a ssh tunnel. It is not the root password on my computer. Is there any way I can find the password out, change it, or just start over and create a new one? I know it isn't a connection problem because I can't login to ssh from localhost either. I've tried reinstalling ssh too.

I have a problem with my ubuntu account. I am running 4 virtual machines, based on jeos-8.04 and I am using a public key authentication to login to my account (via ssh). This is not the problem, I have the key and the passphrase. But when I am logged in, I can't sudo, because I forgot the password for the accout.

I'm trying to configure an autologin account for a kiosk. I can create the user, no problem. I can set the user to automatically log in, no problem. I can set a delay in the automatic login so that someone is given a chance to log in using their own account, no problem. But if the autologin user logs out, then gdm does not automatically log it back in. This is where I'm stumbling. It seems that for such kiosk uses like this such behaviour would be a bug and not a feature.

My mother runs Ubuntu 10.04 on her home computer, but on her workplace they use some version of Windows. Her IT-guy sent her a .rdp-file for logging in to her workplace server. This file doesn't work in Ubuntu, and the IT-department at her job can't solve the problem. Ergo; She's unable to log on to her workplace computer/server from home.

I recently installed OpenSUSE 11.4 64 bit with GNOME yesterday and everything is going fantastic. I like it much better than Ubuntu 10.10 64 bit Maverick Meerkat because it is much more stable, reliable, and dependable. I own a heavily modified ASUS N61JV-X2 notebook PC. I installed OpenSUSE using the LVM based method and LUKS encryption. When I turn on the power to my notebook PC, it asks me for my password to decrypt my Intel 2nd Generation 160.00 GB Solid State Drive. I expected this behavior. However, I never get to see the OpenSUSE login screen. After I type in my password to decrypt my SSD, it loads up the desktop immediately. How do I configure my OpenSUSE so that I can see the login screen so that I can select my standard user profile and enter the user password to login?

Just before Lucid was released, I installed karmic on a vanilla VM in 64-bit mode, and all was good. Did a desktop setup and afterwards installed Eclipse, and I was happy: A new system for coding on-the-go! Now, after upgrading to Lucid with do-release-upgrade -d, I can no longer enter my password on X login. The keyboard just doesn't work for some reason. When I enable the onscreen keyboard, and click my password, I can login. The strange thing is that my keyboard works like a charm after I've logged into my X session?

I've encrypted my root partition with LUKS and cannot remember my password. My main question is this: is it possible to extract the hash (or key; not sure on the correct terminology here) from the LUKS header and run it through a cracker? The hash type is SHA1 and I can remember the characters I used for the password, just not in the correct order (lots of special characters). That being said, given such a small charset, it should be crackable within a reasonable time, correct? Especially if I used a GPU accelerated cracker. What I don't know how to do is go about getting the hash from the LUKS header. Is any of this possible, or am I SOL? Of course, I have physical access to the system so I can boot it into any utilities I may need to.

I'm running Karmic Server with GRUB2 on a Dell XPS 420. Everything was running fine until I changed 2 BIOS settings in an attempt to make my Virtual Box guests run faster. I turned on SpeedStep and Virtualization, rebooted, and I was slapped in the face with a grub error 15. I can't, in my wildest dreams, imagine how these two settings could cause a problem for GRUB, but they have. To make matters worse, I've set my server up to use Luks encrypted LVMs on soft-RAID. From what I can gather, it seems my only hope is to reinstall GRUB. So, I've tried to follow the Live CD instructions outlined in the following article (adding the necessary steps to mount my RAID volumes and LVMs). [URL]
If I try mounting the root lvm as 'dev/vg-root' on /mnt and the boot partition as 'dev/md0' on /mnt/boot, when I try to run the command $sudo grub-install --root-directory=/mnt/ /dev/md0, I get an errors: grub-setup: warn: Attempting to install GRUB to a partition instead of the MBR. This is a BAD idea. grub-setup: error: Embedding is not possible, but this is required when the root device is on a RAID array or LVM volume.
Somewhere in my troubleshooting, I also tried mounting the root lvm as 'dev/mapper/vg-root'. This results in the grub-install error: $sudo grub-install --root-directory=/mnt/ /dev/md0 Invalid device 'dev/md0'
Obviously, neither case fixes the problem. I've been searching and troubleshooting for several hours this evening, and I must have my system operational by Monday morning. That means if I don't have a solution by pretty early tomorrow morning...I'm screwed. A full rebuild will by my only option.

I'm trying to migrate my LVs over to a Luks volume (prompt on password at boot). Unfortunately, as soon as I add my luks-encrypted physical volume to my volume group, I'm no longer able to update my grub configuration. I've detailed my steps below:
I've created and unlocked my encrypted partition with the following:
Code:
sudo cryptsetup -c aes-cbc-essiv:sha256 -y -s 256 luksFormat /dev/sdb1
sudo cryptsetup luksOpen /dev/sdb1 crypto_agilityssd
My /etc/crypttab looks like this:

New to Linux in the last year, used Debian Wheezy off and on for a time - trying to build a system up from a minimum net-install, just to learn more about it.
I have a niggling little problem - either of understanding or configuration. I started with the min install and installed X using apt-get or aptitude. Then installed JWM, which I would start from the console via startx. I really liked this setup, since it was simple and I knew what was going on. This was all on Wheezy.
After the upgrade to Jessie (via dist-upgrade), I would get messages popping up "on top of" the console login when I booted. Stuff like "b43-loading firmware …" would pop up on screen while I was typing my login/password. This was kind of disconcerting (seemed like something must be misconfigured) but didn't effect functionality at all.
Eventually I decided to try a display manager, since that would (I thought) avoid the whole console login process and thus the weird overlapping messages. I installed LightDM through aptitude and it works great, but the console login is still displayed first (briefly, maybe 3-4 seconds) before the LightDM greeter takes over the screen.
It is there just long enough to confuse the unwary, who start typing their login name only to have the screen replaced by the LightDM login screen and have to start over. Obviously this isn't a big deal (everything works fine), but since the whole point of this project was to understand, I'm very curious if this is normal behavior (videos I've seen of folks installing Debian seem to show boot messages jumping straight to the DM without showing:
Debian GNU/Linux … tty1
debian login:
or if I've neglected to configure something that would allow boot directly into LightDM or hide the text console while LightDM loads or … something.

When I boot my Fedora 15 installation it shows me the blue screen with progress indicator, however I do not reach the login screen.Instead I see the textual shell where the last item is:Started Display Manager.It looks like my monitors are not detected anymore. I have been working with them though (this appeared after a restart). I am not sure how I determined it but I read in some log that no display was detected. Nothing changed to the hardware set up however.I see some suggestions to run system-config-display as root.However this command can not be found nor can it be found when I run yum install system-config-display.
