I installed Xubuntu 9.04 on an old Acer Aspire 1200 (PIII, 256Mb of RAM). The install went ok and I was greeted with a login screen at the beginning of every new session.
I later upgraded to Xubuntu 9.10 and since then I've lost the login screen. All I'm left with in the shell (tty1) for which I have to put in my login and password before I can do anything. Typing startx at the prompt starts the desktop.
how I should reinstall GDM or its XFCE equivalent?

I have recently upgraded to ubuntu 10.04 on a machine which I installed the kubuntu-desktop package onto. After the installation I tried to login to a KDE session and my password is accepted. The login screen disappears before the loading splash screen for KDE appears, however this only stays on the screen for a few seconds before the login screen appears again and the drumbeat sound is played (as if you had just turned it on).
Note that GRUB works fine.
UPD (17:48:10 4/06/2010) I have re-installed plasma-desktop, kubuntu-desktop and kdemain packages and this has only caused a longer delay before the login screen is displayed again.
Please could somebody send me in the right direction to get this fixed. I have attached kdm.log.1 as a txt file as this may help diagnose some errors.

I've just ran the upgrade from 9.10 to 10.04 via the online update manager. It rebooted and now hangs at the text screen before any graphical login screen appears. The last line on screen appears to show a failure to connect to a cifs share on my other windows computer.
I've tried to select the recovery menu, which then appears but the keyboard does not allow any of the options to be selected with the arrow keys or any other I tried, I've tried a ps2 keyboard and that doesn't allow any selections either. But it is possible to use ctrl-alt-del to reboot from this non responsive menu.

i've created a completely new user, so config files for fluxbox/unity/gnome cannot be the problem. when i try to login with this user in gdm, the screen goes black for a few seconds and gdm displays again.
tried:
- new user without any gnome/unity/fluxbox config
- tried "ubuntu", "ubuntu-classic", "ubuntu-classic without effects", and "ubuntu-classic safe mode"
- did aptitude purge gdm & installed it again
- nvidia module is loaded properly
- no errors in /var/log/Xorg.0.log
- login with NXCLIENT on this server works perfectly fine

I just upgraded to 10.04 from 9.04 and I cannot log in to the machine. I tried launching the on-screen keyboard but it just flashes and disappears. Anyone else having this issue?I also tried attaching a different USB keyboard, but that didn't work either.

I upgrade my system from 9.04 to 10.04, then when booting, I get the purple wallpaper and mouse, but nothing else, No login menu. I can hopefully connect to my system with ssh from another machine, I update everything, upgrade, etc etc, try to boot on recovery mode, and clean packages and so one...Nothing happens, still no login menu.

I did a upgrade to 10.04 on my server. Then after a reboot I was unable to remotely get into server. Upon connecting the monitor I am greeted with the purple 10.04 boot screen with this text at the bottom:
Code:
The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present
Continue to wait; or Press S to skip mounting or M for manual recovery
Now I did some googling and the results I came across involved a encrypted drive which I have never even tried to setup. Now if I choose a manual recovery I am dropped to cli which from there I can start networking then ssh into the system and run updates, ping other machines, etc. But again this is meant to be a remote access server so everytime I reboot I cant just hit the M key let alone run service networking start! So I commented out the swap entry's in both my /etc/crypttab and /etc/fstab...now I cannot even get to terminal as I could before...now it just loops with no errors!

Recently I decided to upgrade my 10.04 installation the lazy way, by clicking the upgrade button instead of a clean install (32bit). Now, I can only get into Ubuntu with the recovery mode. If I let the system boot the normal way, I end up at the login screen where I (correctly) enter my password and then nothing else happens. I can move the mouse, the clock ticks on, and I can even use the restart button, etc. But the login screen stays gray and does nothing else, so no desktop. With recovery-mode I can use the failsafeX option to get into the desktop, everything works fine there. And even though it calls it a low-graphics environment or so, everything looks normal, its even my native resolution of 1440x900.
My first idea was some driver issue for my Ati Radeon HD 2600 Mobility card, so I looked into that. I've checked/done the following:
- Installed the drivers manually (downloaded from AMD)
- Uninstalled those drivers
- Used aptitude to remove any fglrx things
- Installed Jockey
- Installed the drivers with Jockey
- Removed the drivers with Jockey (Ive read this is the cleanest option)
- "no drivers" at this point
- Use generic/default X config, make specific X config (both from the failsafe X boot thing)
Nothing worked at all, booting still only works with recovery option and then the low graphics mode. Otherwise, it will just "hang" on the login part. When I boot first recovery mode, and then pick the resume option, I'll see some errors near the end of the booting process.
I've seen 2 errors which might be related to my issue:
- "Unable to allocate crypto cipher with name [ecb(aes)]" (home is encrypted, and accessible with safe boot)
- BUG: CPU#1 stuck for 61s!
Now, the second error seems to "match" with hanging at login. I login, something is stuck and churns the CPU... and never gets unstuck, so login just hangs there. However, I can't find any information related to that stuck CPU thing. Only changing PIDs and other numbers/stack traces, no processname or any other name to work with. So I'm at a loss here.
Big dump of possibly interesting part of kern.log:
Code:
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572381] BUG: unable to handle kernel NULL pointer dereference at 00000021
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572386] IP: [<c027c1b0>] sysfs_delete_link+0x30/0x70
Nov 26 20:31:25 lexmortis-laptop kernel: [44.572397] *pdpt = 0000000035f29001 *pde = 0000000000000000 .....
Despite that with low graphics mode everything works, it seems to be a non-graphical issue here (stuck CPU on some process?). Unless I missed another option I can test for the graphics / drivers. ow I could find more info on stuck CPUs during boot?

I just finished the upgrade of 10.10 to 11.04, restarted and now i can't login anymore, i'm stuck in an endless login loop.
1) Boot
2) Xorg starts
3) I see my user, login
4) Screen goes black like it's loading
5) Loop back to login
It's not a password issue, i can login in command line It's not a profile issue cause i tried creating a new user from the command line and it still loops. I looks briefly at the /var/log/... but i couldn't find anything relevant,respond ASAP this is my work PC.
I thought it would be simple since it's a very simple a relatively new machine (2months ago)

Right after I type in my username and password and hear the usual login sound I have to wait about 15 to 20 seconds to get the X desktop. The system load average monitor is at its max and starts to become lower.If I log out and in again I dont get that delay. It only happens with logging in after a reboot/power on.I tried to open a console (Ctrl+Alt+F1) before I log in, move back to X and login then jump to console and use htop to see what's eating up my resources during that time with no luck. Everything seems to be normal.

I had a working workstation with Karmic. Then I decided to upgrade to Lucid. Bad move, it turns out.First the upgrade crashed. Just stopped doing something for hours on end, and I eventually had to reboot. After that, I had to apply lots of apt-get and dpkg love to get the machine to book. Now, I *think* I have a Lucid system, at last. Only that it doesn't work where the Karmic system used to...Our setup uses kerberos and autofs. To begin with, the upgrade lost my /etc/krb5.keytab (making it impossible to log in), but that can be easily replaced.Now, I can log in, but my home directory doesn't get mounted. In /var/log/auth.log, I get this:
Code:
Jun 23 11:13:58 pc13477 gdm-session-worker[1801]: pam_krb5(gdm:auth): pam_sm_authenticate: entry (0x0)
Jun 23 11:13:58 pc13477 gdm-session-worker[1801]: pam_krb5(gdm:auth): (user hans) attempting authentication

I did an upgrade on my system yesterday. After the completion of the upgrade on restarting the system the computer enters tty1 mode straight without giving me the GUI login screen making it difficult for me to work. The question does now is what could have caused this to happen ? Have i gottten something wrong somewhere?
To switch to tty7 mode i hit the key crtl+alt+7 but it gives an error message about an unknown user even after login in with my username and password on tty1. Start the computer on recovery mode and selected the option correcting broken packages and it produced a result requiring me to download some new packages. I have a huawei e1550 modem which i use to browse in Nigeria. I want to know how i can connect to the internet on the tty1 after insertion of the modem so i can download the necessary packages it requested on issuing dpkg command

Today I was prompted to upgrade to Ubuntu 9.1, and then again to 10.04
Doing these upgrades wreaked havoc on my system. I have been able to fix most of the problems that were caused but I am having trouble finding information on the following:
When I boot up the system and after passing the GRUB loader, the system freezes up at the login screen and I have to power down.
If I hit ESC at the GRUB screen and choose Kernel 2.6.32-25-generic (recovery mode) and then choose "failsafe graphic mode", then I am able to log in to GNOME as normal.

I was running 10.04 until yesterday, when it occured to me that I could upgrade to 10.10. So I went to Software Center, set it to get normal releases and left it to do its job. The upgrade appeared to go without a hitch and I rebooted. The login screen appeared. But just before I could click on my username and enter my password, the screen went blank and a second later the login screen was back. But then just before I could click... Undeterred, after half a minute of frantic clicking I did manage to click on my username and get the password prompt. This time, the login screen didn't go anywhere. Yay. To cut a long story short, this is now my standard logon procedure. However, the plot thickens. I appears that instead of 10.10, I ended up with 11.04, Natty Narwhal, which 'was released in April 2011'. If I download an .iso of Maverick and install it over my current version, will it leave my data unharmed AND reset everything so that it works again?

I have upgraded from Ubuntu 9.x to 10.04 LTS after the upgrade, my netbook goes to sleep in a short period of time and makes me login every time i resume. This is very annoying as i have to wait for login and sometimes my wifi connection drops. I just quickly want to check my messages. The delay is annoying and has me using a windows (argh) laptop instead. i miss my ubuntu netbook.
i have tried adjusting power management setting to never go to sleep and adjusted some other power management module from the command line, but with no luck. is there a way to reset the sleep pref's or any way to fix this.

After a recent upgrade I'm now completely unable to log in to my computer. GDM autologin lets me start my computer and enter gnome as before, but su and sudo wont let me access my root account. If I start in single-user mode and try to change my root password with the command passwd I drop back to the shell after entering my current password, no error messages. Same with su and sudo, just drop back to the terminal without error messages. I am running ubuntu jaunty, any idea what's happened?

I just upgraded from 9.10 to 10.04 beta and now I get the login screen - but after logging in, all I get is a blank screen with a black bar on top showing just the time on the top right hand corner. If I CTRL+ALT+F1 and reboot using the command line, it restarts showing mythbuntu on shutdown. Im have nVidia GEForce 8600 - is this due the X crashing? I tried all these - no change
Code:
sudo dpkg --configure -a
sudo apt-get install --reinstall ubuntu-desktop
sudo apt-get install -f

When I boot up my password is requested three separate times by the keyring. Sometimes if I have left my computer to boot up it will actually be requested four times. I get the impression it relates to start up programs, for example if I leave it so that it requests the password a fourth time, at the same time the wifi connection settings pop up requesting the wifi password. I remember having a similar problem before and I think I was able to set a program as always having access to the keyring once logged in, but I can't remember or find how to do this. The programs that are maximized on startup are; transmission, liferea. Docky and gnome-do are also arranged to load on startup.

Since upgrading my Debian/unstable amd64 installation a few days back I can no longer log in as either root or user, whether to SDDM, via the console, or via ssh. When trying with the console, I can see the login message flash briefly on the screen, before the console resets itself.
I can boot into recovery mode, and examine log files. I enabled systemd debug logging and, amid reams of messages, these seem the most pertinent:
Sep 25 02:24:43 cooler systemd[1]: Received SIGCHLD from PID 937 (login).
Sep 25 02:24:43 cooler systemd[1]: Child 937 (login) died (code=killed, status=6/ABRT)

After upgrading from FC10 to FC12 here I notice I cannot login to the GUO console locally as root, yet this worked with FC10. Attached is my /etc/gdm/custom.conf settings and I've got the login for root set true whih is where it was and working prior to the upgrade.. Also I don't see the shutdown/restart options as before either:

I've recently upgraded my hardware. Now, the system boots perfectly fine, but I can't login to the tty as root or any other user. Infact yes, I can login, but as soon as it shows Last Login, it exits and then I'm back to a login prompt. I've successfully booted into single user mode, and changed all the passwords, but still it fails. X doesn't start, although I think it's due to the old xorg.conf having the wrong driver.

About a week ago I used preupgrade to make the transition F14 -> F15 on a x86_64 workstation.
The system has been fully updated ever since, but I'm still not able to login either with KDE or Gnome. With KDE, the login process freezes before completion, whereas with Gnome I get the "wallpaper" behaviour reported here: [URL]
Funny though, I can login in the KDE failsafe session.
I could find no other thread reporting this problem and am at a loss on how to start diagnosing the problem. If anyone out there has any suggestion, I'd welcome it...
what's the difference between a "regular" KDE session and the failsafe one? They both look & feel the same to me...

I have a Fedora Core 6 web server I've been testing. Everything was working fine(http, mysql, etc) until I installed Shorewall. After a reboot, now I get "(NONE): LOGIN" From what I've googled on this, this isn't an uncommon error, but I don't see any consistent way to correct this issue. Everyone just says boot single user and change roots pw. But thats where I run into problems. When I log in single user mode and try to run "passwd" to change root pw, I get "module not found". I've tried running vi(vim) to edit /etc/passwd but I also get an error about a library file missing. So, I'm at the point of thinking about reinstalling FC6. I'm assuming I should upgrade to a new version of FC. If I do this, will it "break" http and mysql? What version would be safest to upgrade to from FC6? Would it be better to just reinstall FC6 on top of whats there?
