Ubuntu Installation :: Can't Login To GNOME After Upgrading
May 4, 2010
Yesterday I did a successful upgrade to 10.04. Today, after a few hours of using and a few reboots, when I provide my password in GDM, the screen turns black and gets me back to the GDM. The same with recovery mode.When I turn onto the terminal I can't see any letters but a bunch of blurred lines on the top of the screen. In recovery mode the terminal works properly.GDM also works properly. Neither graphics, nor the resolution has changed.

I added the repo Index of /repositories/GNOME:/STABLE:/3.0/openSUSE_11.4. Then did
Code:
zypper dup
After the installation completed I tried to logout (from Gnome 3 shell) but couldn't. A notification appeared saying "cannot find gnome save session" or something similar. Then pressed ctrl+alt+F2 then used the reboot command as root. After booting the new looking login screen appeared but after typing my password when I tried to login it said "something has gone wrong" and the only option which I see there is logout.

yesterday I updated my fedora 13 to fedora 14 (on laptop) and today i cannot log in on user. It just go blank for a sec and is back to login.
At text console (alt+ctr+f2/f3) i enter my username and pass it give this for a sec and resets (clean) console
username: Name
password:
last used: [date]
login: no shell permission denied
i used unetbootin (fedora 14 netinstall to update) and later i updated 1,5G before reboot (did update that fix, forgot its name tho :s)
I would most likely reinstall everything, but i have some work at laptop and as death-line is near, i would prefer to fix it if possible.

i have installed F13 on unused space, is there a way for me to access and fix it? or at least get some files from there?

I have a problem after upgrading from Kubuntu 9.10 to 10.04.1 (LTS): after reboot I get the login panel but when I type login + password, the system begin to go ahead but immediately comes back to login panel, so I can't get the Desktop obviously .
I checked the following : The kubuntu-desktop is already in place the kdm I think it works well (start & stop work) and the file xorg.conf has been rebuilded with the cmd "dpkg-reconfigure xserver-xorg".

I can't seem to login to X after I've upgraded from F13 to F14 (x86_64 KDE Spin). I retained my /home partition with my user account etc.
The system fails when I try to login to the account I had on F13, but if I create a new user account I can login to X.
I did have the nvidia proprietary graphics drivers installed... how to track down an X issue like this relating to logging in to a system via the GUI?

I just did a distribution upgrade on my laptop from 9.1 to 10.04, and it went fine for the most part except this issue. After it boots up, I don't see any window titles/scrollbars/borders and on clicking the icon for "Show desktop" on the bottom left, I see the following error message:
"Your window manager does not support the show desktop button, or you are not running a window manager."
After googling a bit, I realized that gnome-wm is not starting automatically and so I have to manually start each time to see the windows working properly. Can somebody tell me if there is a way to make sure that gnome-wm starts automatically? I know I can put it in my .bashrc but I want to do it the correct way if possible. If not, I will have to go with that workaround.

I am trying Xfce in my Ubuntu Karmic installation. I just logged out and I get the Xubuntu login screen. I prefer the GNOME one, and xubuntu-desktop sets Xfce as default. I tried editing /etc/x11/default-display-manager and it already says /usr/sbin/gdm.

I'm having this problem with Ubuntu 9.10, it has happened the three times I have tried to install it.
I have made a video showing the problem: [url]
After upgrading and rebooting, the flashing login screen appears and it is not possible to use the GDM.
I have tried to install KDM and it works, but when trying to load gnome I get the blinking bars again.
I have also tried this (and got the same problem); installing the Nvidia driver (manufacturer), installing the Nvidia driver (repositories) and installing no screen driver.
I think the problem is with GNOME, and not with the graphics card.
Now I have installed windows xp :-/, for the first time in a whole year, cause it is not possible for me to use Ubuntu 9.10 at all.

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...

Here's the error I get:
"The configuration has not installed correctly for Gnome power management".
Updated my 11.04 install via the update manager last night. When I turned my computer on today it wouldn't boot into the normal gui desktop. Where my normal login screen usually appears a different login screen appears with my username. I login. Screen flickers black for a few seconds and a page with a ton of text shows up for a fraction of a second ( too short of a time to read a single word). more flickering. Then I am returned to the slightly different login screen once again with the error. I tried booting into failsafeX gui mode. Same issue.

I tried to install Compiz on F9 Gnome and I added a startup entry (system, preferences, personal, session, startup programs). Now I can't log in to the gnome window manager, it logs in and then logs out again. I would like to remove the entry that I created in the startup programs, but I don't know which file to edit. Where the settings to the System > Preferences > Personal > Session > Startup Programs are stored.

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.

I have recently upgraded my System from F13 to F15.
I use an ATOM Board with an Intel N10 graphic chip. It worked without any issue with F13.
F15 boots up, I can see the blue screen with the Fedora Logo. Then it changes to the background picture of gnome and thats is. No login screen. I checked the logs but I am unable to find any hint, why gnome does not boot up completley.
btw: With TigerVNC I am able to login.
What can I do, to solve this problem?

I have installed Ubuntu 9.10 on my Dell GX240. I have severe difficulty logging in. If I try to login on GNOME or GNOME fail safe mode , I just cant get in . I keep getting the login screen again. I am able to go into terminal mode. Sometimes I have to try upto 100 times to login in GNOME or failsafe mode. Once I am in everything is fine. Is there a way to do some troublshooting? Also transfer to USB sticks is very slow - sometimes as slow as 1MB per min. Is this normal with Ubuntu?

I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.

As the title suggests, I am running Ubuntu inside a VMWare environment. I did the upgrade to narwhal and I see the boot-up screen just fine but when I get to the screen to log in to my Ubuntu account this is where Ubuntu freezes up completely and I get nothing out of it at all. I do have VMWare upgraded to the latest version that is available as well.

I upgraded my Fedora Core distribution from 12 to 14. Everything worked fine, except for SQUID which refused to upgrade. I then went to rescue and installed SQUID using yum and then restarted the upgrade. It did finally upgrade the system and then asked for a reboot. Well, when I selected the new kernel option in the GRUB options, since I also have Winduhs, it gave a kernel panic. I tried booting into the older kernel and it worked. Now I see the users that are there in the system in the Graphical GUI login greeter screen. But none of the users get authenticated. I used the rescue option and removed graphical login and changed boot level to 3. I also enabled the root user. In the rescue mode, if I do a startx, everything works fine.
I logged off rebooted the system. When I login, I see the version is shown as Fedora Core 14, but the kernel was still the older one with Core 12. I again went to rescue and checked out GRUB and saw that it had no initrd for the new kernel. I created a initrd image with the mkinitrd command and then added it to grub. I again rebooted. This time it shows the correct kernel, but still the system does not allow any of the users to login. All the Logins fail. I have tried going to rescue and going to the system using 'chroot /mnt/sysimage' and doing a startx for Graphical. Everything works, but only with the Rescue mode in the DVD. The normal boot/login sequence does not work.
Incidentally when I do a 'yum distro-sync', I get something like this :
---> Package dialog.i686 0:1.1-9.20080819.fc12 set to be downgraded
---> Package dialog.i686 0:1.1-11.20100428.fc14 set to be erased
---> Package diffstat.i686 0:1.51-1.fc12 set to be downgraded
---> Package diffstat.i686 0:1.51-2.fc14 set to be erased
---> Package diffutils.i686 0:2.8.1-25.fc12 set to be downgraded
---> Package diffutils.i686 0:2.8.1-29.fc14 set to be erased
It still seems to believe its a Fedora Core 12 system. Another information is that when I leave rescue mode and do a normal boot without installation media, it starts doing some SELinux relabelling and reboots. Any pointers on how I can get the system working. I am able to work with the rescue mode way, with any user, as it does not ask for any password. I can even do startx and work on the GUI. All my data is also there. I just am unable to get the user authenticated using normal boot/login. I have tried using passwd -d username, but it gives an error :
passwd: libuser initialization error: could not open configuration file `/tmp/libuser.ElY0r9': No such file or directory
In fact, I am now in rescue mode only when I am writing and sending this.
My GRUB file is :
default=4

After I did all steps in that DOC, I've rebooted the system, and then Debian booted in TTY( gdm didn't start!!!!! )
and the main problem is I can't login to TTY and it say's "Login incorrect"!! (I'm sure the username and password is correct).
Overall :
1- GDM doesn't start
2- I can't login to TTY

I was recently watching an avi file, when suddenly, my tower (the computer) got really, really noisy. That's pretty normal when I'm on my Windows side, but very unusual for Ubuntu Linux. I knew something was in the wind then and there. So I exit my Dragon Player to discover that ! gasp ! KDE is down, replaced with the default wallpaper for GNOME, and no bars anywhere. I reset the system only to find that it refuses to boot into either KDE or GNOME. Having been in something similar to this situation before, I decide that Xorg.conf must be broken somehow. In an effort to get to the GUI where I can safely edit it, I try reinstalling KDE and GNOME, which both failed.
So I try installing xdm...which results in only being able to access the login screen for XFCE. Whenever I try to log in using the correct credentials, it simply refreshes the log-in screen.
1. Is this, indeed, the sign of a broken Xorg.conf, or a broken Xserver in general? Or is there something larger that was changed?
2. How do I fix this? (I've already tried using Ubuntu 10.10 64 in rescue mode, but I can't seem to change anything in the system itself.)
3. Is this possibly a result of upgrading straight from 10.04? Is it possible that having both KDE and GNOME contributed to this?
