Ubuntu :: Gnome Hangs After Login?
Jun 5, 2011
I have today done a clean install of Ubuntu 10.10. Afer the install I needed to upgrade my video driver (nVidia GeForce MX). I managed to find some instructions to uninstall the existing Nouveau driver and install the nVidia one. This all worked absolutely fine. The first time.
On subsequent logins after the login screen the system just hangs. I get a background screen with shades or purple and a working mouse but nothing else.
I can get to a command prompt (CTRL-ALT-F1) and Ubuntu seems to be working fine - it just seems to be a graphics 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.

I've had my system about a month -- 10.10, i7, 8GB RamLast week, I installed KDE and xFce desktop environments.Two things I wonder if you can comment on:1) It boots up into kubuntu instead of Ubuntu, and presents the kubuntu login screen, even when I last used the Gnome environment.This is the curiosity.When I log in, the screen brightens and then plays the Ubuntu default sound, and drops me into the Gnome desktop.2) This is the issue -- every so often , maybe every 5 or 6 logins, after I have logged in, the screen up as normal, but just sits there, empty. I have to Ctrl+[F2] to log into the text interface and issue init 6 to reboot. On the second attempt, it takes me into the Gnome desktop as at other times.

I have a desktop running Hardy and till friday it was running good. Today is monday and I guess it has got monday blues like I get every monday at work.Today I tried to start it as usual but it just refused to go further than login screen. I just can not login. It just hangs it there. I do not know what has gone wrong. I did not change anything since friday and no one else uses it. Theres nothing in logs that could give any idea. It just hangs without any reason and is still on the login screen for ever. It does ask my username and password but then it does not go further.But to my surprise I tried logging in with root and it gave me expected error that system administrator is not allowed to login from gnome.

I am using Ubuntu 11.04 and it hangs as soon as I start to enter my password on the login screen. The way I am currently booting up is using failsafeX which is leading to no sound on my laptop.
I tried deleting .gconf/.gconfd/.gnome2_private/.gnome2 folders and it didn't help
This is the output to the lshw command: [URL]
I put this up since I have no sound on my system in ubuntu ( no effects mode ) and now even on Windows there is no sound (strange)
I also tried deleting the /config/autostart/* files and it didn't help.

Just installed Lucid Lynx on my Desktop and after logging in I would get a 15-20 second pause before Gnome appeared. I found many many potential solutions for this problem on the Internet but none solved it. Finally figured out that it was due to the system seeing a floppy controller when I have no floppy drive. I was led to this conclusion by the following two lines in my syslog (System > Administration > Log FIle Viewer > Syslog).
May 1 18:27:04 Desk-Ubuntu kernel: [ 34.636665] end_request: I/O error, dev fd0, sector 0
May 1 18:27:16 Desk-Ubuntu kernel: [ 46.813441] end_request: I/O error, dev fd0, sector 0
Note the 12 second delay when it tries to read again.
So if you are getting the pause and seeing the same thing your system log then ...
Enter your BIOS and disable the floppy drive Use sudo and edit /etc/fstab commenting out the line with fd0 in it
Hope I can save someone else the headache of hunting through the Interwebs and finding 5 different solutions none of which worked. Learning as I go with Ubuntu so I didn't even know how to carry out most of the "solutions" which required more googling. I am migrating from FreeBSD due to application requirements

When I try logging in using any user name, ubuntu just returns to the login screen. I cannot actually log in. I used the recovery mode to create a new login with password 123456, and the same thing happens. What could it be? Ubuntu worked just fine for a while, then DKMS started causing problems, I had errors with upgrades, software installs/uninstalls, then my sound went. I found a great fix for the sound (https://help.ubuntu.com/community/SoundTroubleshooting), the sound came back, but then I could not log back in again. I cannot find any help for this issue, and had to install 9.10 Karmic Koala, and that's what I have been using for the past couple of days.10.04 has been fairly buggy for me and I am considering staying with 9.10, or going to another Linux distro.

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?

In Lucid Lynx, if you install gnome-do, then the system freezes at startup. The only solution is to uninstall gnome-do.
any workaround to this? I really like having gnome-do launcher

I'm running Ubuntu 10.04 Server x86 64-bit and installed likewise-open, which I think is version 5.4. I can authenticate with Active Directory credentials, but it seems to hang when I log in. I can press Ctrl-C and break out of the hang, but was interested to see what was causing the behavior. I noticed lsassd was taking up about 99% of CPU while in this hung state. I then did a
Code:
tail -f /var/log/syslog and discovered lsassd was doing some type of query for what appeared to by every user in our Active Directory as I saw hundreds of entries like this being added to the syslog:
Code:
May 25 14:21:27 coe-web lsassd[1225]: 0x7f5bc72c1710:The user attributes in the cache data for 'domainjohndoe' are invalid. The cache database or user data in Active Directory could be corrupt.
Is there some setting I can change so it doesn't do this?

I have been trying to use f-spot to export pictures to facebook. I looked around and saw some people's hanging on fetching albums or whatever. My login hangs on "session established, fetching friend details", and eventually gives me the login button again, which I press to no avail. I run f-spot --debug and get no error reports.

I just installed Ubuntu 10.10 on a vostro 1000 laptop using standard configuration.I repartitioned the whole disk for Ubuntu. Now, when starting up Ubuntu, it appears to log in fine, but right near the end of the theme and before the desktop loads, it hangs, repeating a slice of the intro music over and over again. What could be causing this problem?Note: On every ubuntu disk I use, it also says that modules/..../Kernel something is missing from the disk quickly before booting the live session.

I'm running Maverick on an Acer AO521 netbook. I've got a k125 processor and an ATI Mobility Radeon HD 4200 series video card.Since upgrading to 10.10 with the new version of gnome my computer has started getting stuck on blank screen when booting the GUI. Not every time, but most times i boot.If I boot to command line through GRUB there's no problem. When I try to run gnome from the command line i get the same problem.

I'm in LiveCD (Natty) I blew up the OS. Can't get past login & password. 'Puter just hangs there. I'm going to do a clean install, but want to make a copy of my /home. I tried gksudo nautilus to copy all of /home to an external hard drive (via USB). It won't copy all, saying that I lack permissions. I've read about recursively copying, etc. and cannot make out the sequence I need. I must copy all that is in my /home and preserve all the links, dependencies, file and directory ownership permissions and also must get the command for copying them from the external hard drive if the clean install goes bad.

Under GNOME, the X server hangs about every hour under regular use. When this happens, I can usually move the mouse pointer, but nothing else. I can't click anything, I can't type anything, etc. I have CTRL-ALT-Backspace configured to restart the X server, and that works if I do it before it hangs: after it hangs, that doesn't do anything. The only thing I can do right now is reboot the entire machine.How can I figure out why it is hanging? Also, can I somehow restart the X server without rebooting the entire machine?

Seems like a nasty bug in F13.after typing in wrong password, a 2nd correct attempt on gdm (or kdm) leads to a dark screen with a dash cursor blinking on the upper left - have to turn machine off. Then on next login, memory seems to race until properly shut down.

After Gnome logon it may hangs in any moment (window scroll, app start, opening url)
If sound was playing in that moment it continuously repeats last sample (about 1 second length), but do not respond to mouse move/click or keyboard. If to let it stay in this state nothing change - sound sample still repeats and no response to input. I need to reboot it by reset button. Sometime when I press reset nothing happen then after couple of seconds computer turns off, after 1-2 sec on and then starts booting.
During first 15-20 minutes after booting it may hangs multiple times but after that it works without problems.
Tried do not logon 20 minutes after boot - do not help, it hangs anyway. Only helps logon and do nothing for awhile.
This behavior have started after F12 installation. F13 installation changed nothing, only F11 worked perfectly.

.
Its not only this, but there is no other sounds enabled - for mouse clicks etc

I have been searching this forum and google extensively for the last few hours, and I cant dig up anything useful. I have a very weird problem:
Install Fedora 12 from livecd on a widescreen monitor:
- Using Nvidia 96xx drivers for my Gforce2 MX
Everything runs fine at this point. Connect old 17" flatscreen and no network: Login freezes for about a minute after username selection, no password prompt, no mouse movement, no keyboard response, after timeout I return to login screen before username selection .. and can repeat this or.. At that point (or before that point) I can ctrl+alt F2 to 'terminal' screen, login works fine.
init 3, login as root
startx
Works fine then, resolution is %^# tho, and cant change it at that point due to errors I get. I'm convinced the problem has nothing to do with my X configuration tbh. Booting from the LiveCD on this configuration works fine. I am tempted to think it has something to do with my GDM, but as my knowledge is limited, I cant figure it out. If I reconnect the widescreen, it all works fine ...

I installed openSUSE 11.4 today and I have a problem. After login, KDE Plasma hangs for about 30sec and I can't do anything. The keyboard and the mouse are working, but if I click, I don't get any response only after about 30sec.
This is a fresh install, 32bit, I'm using only the Oss, Non-Oss and update repositories and the system is up to date.
I have an nvidia 9500M GS graphics card, first I thought it is a driver bug, but I tried both the stable 260.19.44 and the latest 270.41.03 drivers, and was no difference.
I made an another user to try with a clean kde, but the same happened.
I have nothing in my Autostart directory, and I cleaned also the /etc/xdg/autostart dir, leaving there only the pulseaudio related files.

Running Gnome on Jessie. Have had Gnome hang a few times over the past few months. The hangs seem to be related to having open and / or closing a root terminal. It has happened on a Gateway AMD Phenom II tower and on my Gateway NV59 lappy with Pentium P6200.

Can't boot 11.3 gnome live cd on my x86_64 system with Radeon hd 4650 agp. Boots into a black screen and hangs (two tries). Boots fine on another pc with on-board radeon pci-x.It also doesn't work in latest Virtualbox. Need I remind you: very, very bad impression for non-linux afficianados...I'm a happy user of 11.1 and 11.2 on same physical pc.

I'm running an LMDE install, but with the Sid repositories.Everything has been fine until yesterday's updates, after which I can't boot normally. The boot hangs at the login screen, and nothing works - not the mouse, the keyboard, the touchpad, nothing, and it requires holding the power switch to get out. I can boot to a root recovery console, but networking doesn't work at all there. I can run startx there and get an X desktop as root, and networking still doesn't work. No wireless, no ethernet, no nothing. From the recovery console I can run shutdown, and when prompted for a password, can enter Ctrl-D, which immediately drops me back to X, to the normal login screen, which now works normally, and I get a normal X session in which everything works. This is the same for all installed kernels, including 3 versions of the Liquorix kernel and the standard Squeeze kernel. It would appear to be something in my settings in /home, but I can't find anything that looks suspicious. I ran smxi again after booting through the root console, without any improvement.

I'm using Debian Stretch with Gnome and Cinnamon. My desktop computer sports an nvidia geforce 970 gpu (this may be relevant, and it is the reason I had to go with stretch.) I'm not a very experienced linux user but I get along fine.
I'm sharing my computer with my mom and whenever we have to switch users, the computer seems to shut down for 35 seconds: the screen doesn't receive signal anymore. After a new user is chosen, it takes another 35 seconds to get to her session. This is embarassing because my os runs on an ssd and everything else is nice and fast. At first I thought it may be a matter of us two not using the same window manager or not using the "default" window manager, but changing window managers didn't work.
Today I learned about the existence of /var/log/syslog and I decided to check what happened to it when I switched users. I can't post the whole log of what happens because it is too big, but I put it on pastebin : [URL] ....
I understand almost nothing of what is written here, but I saw some interesting things:
- after 35 seconds intervals where nothing is logged, there is a stall on cpu detected (lines 68, 500)
- my gpu seems to have something to do in all this
