Ubuntu Installation :: Desktop Session Crashes To Login Screen Soon After Logging In?
Oct 10, 2010
After upgrading my netbook (Eee 1005HA) from Ubuntu Lucid to Maverick, I can log in okay, but it crashes back to the login screen a couple of minutes after logging in, after the desktop has loaded. I haven't been able to find anything in syslog/dmesg/etc. about why this is happening, but it isn't happening on my other laptop which I just upgraded to Maverick as well.
Edit: memtest86+ showed no errors and the live USB desktop works fine.

When I start a screen session over SSH, I can edit and save files from within the screen session before I log out of the SSH session. But after I log out and log back in, I find that the screen session has lost write privileges, so that I can no longer edit or create any files, even within my home directory. How do I prevent this from happening?

recently had to reinstall ubuntu 9.10....after all the updates & changes i made in synaptic and some restarts, i wanted to proceed in installing my nvidia drivers, so i stopped gdm and attempted to login as root, but it would not let me. it's strange because i created the root account password prior to this.
so, issuing the command to restart gdm brought me to the login window. after logging in, the screen remains in the login splash and a small terminal appears in the upper left corner. can't seem to get gnome started up.

I have a new install of xubuntu 10.10, everytime I try to choose a screensaver the user session crashes back to the user login screen? The video card is an onboard ATI Savage on a Gigabyte motherboard.

I want my Ubuntu 10.04 to login to an Xterm session every time, so I changed it to auto login to Xterm in the login screen settings. This worked fine until I went to do something in a gnome session again, and now even though it is still selected as logging into Xterm automatically, it logs into a Gnome session. Can anyone help me with fixing this?

Just recently I noticed that I suddenly couldn't open any folders, just getting a message in my bar saying it was opening the folder, then it'd immediately close. I also could not right click on my desktop. I removed and then reinstalled Nautilus, then reboot, but now my problem has worsened.
I can no longer select a session type at the login screen, and after logging in I just get a small terminal window in the top left of my screen while the rest is the background for the gnome login screen.

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.

When I start up my computer Xubuntu is asking me to login (which is strange as I have login disabled). Then, when I do enter my password, it is accepted and after a few screen changes I am returned to the login screen. (I know the password is correct as the login screen informs you immediately if you enter it incorrectly.) Also, I can see that my display settings have been changed--the monitor resolution is wrong--my cursor is way big as are buttons, text etc..

If I log out of my initial login session, the login w/ username+password screen is *sometimes* shifted to the right (so that the power icon on the bottom right is off-screen, and I have a black column on the left). When I log back into an account, the same shift *sometimes* happens, independent of whether or not the login screen was shifted. User switching *sometimes* results in the same behavior (it's not just logging in and out).
I have also logged in using a different desktop manager (openbox), and have had no issues (so far) with shifted graphics. Logging back out from openbox, the login screen still *sometimes* has the shift.

I like very much the Guest Session feature of Karmic, it comes very handy when someone needs to use your computer. However, it's only available if I'm already logged in, it won't show this option at login screen. Is there any way to make this possible? Also, I once tried the guest session and configured its appearance to my taste. The next time I entered, though, the default desktop reappeared. I know this happens because no setting is permanently stored for this session, so the only solution I can think of is to change the default configuration it is loaded from.

I learned how to do this on the 'net somewhere. This HowTo will help you create an account on the login screen that will log in the same guest-session seen in the user menu. The advantage of this is that it will be an easily accessible guest account, while not preserving any files or changes on logout, and a higher security model for the account. Confirmed to work on 10.04 - 10.10, but the directions are for 10.10
1. Under an existing administrator account, go to the menu entry System --> administration --> Users and Groups.
2. Click Add. you may need to provide a password at this point. Name your new user anything you would like, except guest. The account cannot be called guest, but visitor does nicely. encryption of the account is not needed. This account will be a "booster" account to guest-session.
3. On the next screen, enter a password, and make sure that you click the check box "Don't ask for password on login", Click OK to finish.
4. As an extra precaution, click Advanced settings, when back on the Users and Groups screen, and on the User Privileges tab, uncheck Monitor System Logs.
5. Exit the Users and groups menu, and then log out and into your new account.
6. Once there, make a folder called GuestManager, and in that folder, make a plain text file called Guestmanager.sh, with this code in it :
Code:
#!/bin/bash
# Launches the guest session
/usr/share/gdm/guest-session/guest-session-launch
# Logs the user when done
/usr/bin/gnome-session-save --logout
7. Save that and then right click on it, go to properties, and then go to the permissions tab. On this tab, click "allow executing file as program", and then close that window.
8. Open the menu entry System --> Preferences --> Startup Applications, and once there, turn off all the startup applications, and then click add. Fill in the name and comment as GustManager, and for the command, enter /home/visitor/GuestManager/GuestManager.sh, where visitor would be the name you picked for the account in step 2. click add, then close
9. Delete all applets and extra toolbars (might want to leave the main gnome menu), and set the background to black or something else bland, and log out. Since this account is just a "booster" none of these toolbars and such will be needed, so removing them saves memory and load time.

i am wondering if it is possible to do this all i can find with google is idea proposals and brainstorms i know i could make a separate account and call it guest user bu that user would get to keep data/settings where as a guest session places a temporary account in the /tmp folder which combined with a ram disk for /tmp would result in some really fast performance since i use a ssd for / which would make the traditional hdd only used for /var also since /tmp would be a ram disk it would be like the guest is using a live cd with security restrictions and performance enhancements on top of this there would be no trace of the guest on my computer after shutdown

Since I have upgraded to Lucid (and thus to Mozilla 3.6.6), I am experiencing a bunch of annoyances with Mozilla.
1) logging into my GoDaddy account keeps displaying the login screen and not my accounts page (yes, I checked the password)
2) creating an account in bugzilla resulted in an "Invalid OpenID transaction" error message instead of a confirmation page
3) the [URL] page popped up a parser error instead of the website.
Midori and Mozilla 3.0.8 work just fine. Does anybody else have problems with mozilla 3.6.6 and above?

Basically, the problem is, we have a bunch of computers in a computer lab, that we want to students to access, but not modify in ANY way. That includes backgrounds or whatnot. And after restart, any changes they may have made, change back. Also, they can't have read access to the administrator account on the computer.
This needs to give a permission denied, or something:
Code:
cd /home/(admin account username)
ls
The Guest Session is exactly what we are looking for, but try as I might, I can't get it to work. Because, we don't want to have to login as administrators, then activate guest session, just for our students to use the computers. The idea being, we can leave the computers in there, and not worry about the students breaking anything.
One thread I tried was: [URL]. However, using his method, will log the student into the account, and after about 5 seconds, log them back out.
The other method listed lower in the thread,
Code:
/usr/bin/guest-session
Seems to work, but upon logging out, fails to launch the gdm
Only way to restore is restarting the computer.

I had openSuse 11.3 KDE4.4.4 installed and used the 1-Click install to get the nVidia drivers. However, this gave me the problems with Amarok and other applications crashing. I switched the system repos to use packman but that didn't help.
The solution on the forums seemed to be either recompile with an old nVidia driver or upgrade to KDE4.5 as most people were reporting to not see it under 4.5.
Upgrading seemed to be the easiest method, especially as there appeared to be a stable repo now.
I upgraded and now plasma-desktop crashes on login! Is getting the old nVidia driver my only option now?
zypper lr -d
Code:
# | Alias | Name | Enabled | Refresh | Priority | Type | URI | Service
--+--------------------------+-----------------------+---------+---------+----------+--------+---------------------------------------------------------------------------+--------
1 | KR45 | KR45 | Yes | Yes | 99 |

I upgraded 10.04 to 10.10 (32bit), the upgrade process didn't go that well because first it didn't boot beyond GRUB. Solved this by unplugging my keyboard (my ubuntu is a server machine without keyboard or mouse, I like to use the desktop version through vnc). After that is booted to shell, which was not so nice either. This time it was the legendary nouveau driver which sorry for my language I will never install again (caused major problem twice already). Installed nvidia drivers and got a display for X this time and it booted nicely to login screen.
My problems have arised since the upgrade, the system will randomly "crash" and go straight to login screen, ending my current session. Sometimes my mouse cursor even changes to the X-mark. I can't see anything in gdm, x11, syslog etc. that would explain the crash. So far I've found best log from .xsession-errors which is here:
[Code]...
I got a lot IPv6 errors on the same log too, but those were caused by utorrent+too old wine. Didn't remember that upgrade deletes/disables extra-repos and I was running the stable wine (1.2.1) instead of the latest one (1.3.7). Upgrading wine solved the error from utorrent IPv6 connections.
So any ideas what I could do to fix these crashes? I'm not so much into clean re-install because of all the configuration I'll need to do then. I do have home on a separate partition but there's lots of software to install and configure.

I saw some pictures of Kubuntu online and thought it looked awesome. I installed it from Gnome using the command "sudo apt-get install kubuntu-desktop". It installed fine, no errors. I logged off and picked Plasma Workspace or whatever its called from the menu and it showed a black screen for about 7 seconds, then showed a clear bar with a hard drive icon fading in. Then it crashed back to the login screen. I rebooted and tried again: same thing. I installed xfce and it works perfectly. Gnome still works. Ditto for Unity. But kde keeps crashing. PS: Graphics card is an ATI Radeon.

I just put on my Linux PC now and after booting logging into the user a/c, it just gives a blank screen with the desktop wallpaper - no menu's or anything, so there's pretty much nothing I can do. I know I had removed the menu and replaced it with the dock (awn dock or something).
However, I can log in as root and root works fine (so I'm doing the update at the moment).
Coming back to my question, I used to know an Ubuntu command which I put in as sudo (terminal)and it used to work like a magic command which would literally restore and repair my linux installation - I even used it when I bought a new system and transferred my linux hard drive from my previous machine to the new one and this one command actually setup and prepared my linux installation to work smoothly in my new PC - just one command after connecting my h/drive in the new PC.

any ideas where I might find some error messages telling me what's going on?
this seemed to happen when I was running "blender" and making the machine do some heavy number crunching, it actually locked up.

I'm currently using Fedora 11 Gnome and I installed the Kde core desktop. However, when I logged out there was no way I could change the session. I installed kdm, but after searching on google I found out that i need to change /etc/sysconfig/desktop to make kdm the default login manager. However, such a file did not exist. How can I change my session?

I cannot start the desktop session: After upgrading from 10.04 to 10.10 (dual-boot system) via Alt+F2 as suggested on [URL]. Grub loads fine after reboot (booting Windows works, Upgrade without errors). If I boot Ubuntu (no matter which Kernel, etc.), I end up in shell (black screen + prompt, stating the new Ubuntu version) and being asked to log in. Entering my name and pw results in the shell prompt changing to my name, but nothing else. So how do I start the desktop session? Repairing packages had no effect...

I have recently downloaded and installed Ubuntu 11.04 desktop. I'd like to be able to dual boot into Windows or Linux on my PC so I've installed in on an ext4 partition on a separate drive from Windows. The installation process ran smoothly and the dual boot functionality works as planned. The problem I'm having is that after logging in, the login window disappears (as does the options bar at the bottom of the screen), and then nothing else appears, just the mouse cursor (sometimes the loading icon, sometimes not) and an empty background image, no icons, no menus. It doesn't matter how long I leave it for, nothing ever happens from this point on. I am technical, however, unfortunately ,I'm very new to Linux (something I'd like to remedy) so I'm a bit stuck with what to try next.

my ubuntu 10.10 64bit (in Dell Latitude machine) login screen is not working. the blank bar to type username and password is not appearing at all. In a quick appeareance there also a sentence: "permission denied". I've tried to browse this forum and seems no answer. I still can access the terminal though using alt+ctrl+F2 but i don't know how to access the desktop because when i hit alt+F7 it come back to login screen. how can i fix it? I have several files in the laptop that need to be saved, if not I probably just clean install it.

I have used Ubuntu since 7-4; I now have 10.4. However, in the last week I have been taken to the login screen three times. This could be potentially calamitous. Ctrl+Alt +Backspace have by default been disable since 9-4. There is no way I am pressing atl+Prtscr +K. I wonder if there is a new zap command in 10.4, and if so, how to disable it. I have never found the need to go back back to the login window. I am generally using the command line when doing this.

Put an remote desktop launcher on the lucid login screen.
I'm running a ubuntu lab, and adding an rdesktop launcer to the login screen would really make login much easier for the users, so they don't have to login twice. First into lucid and then into windows with rdesktop.
I'v already made the rdesktop launcher on the lucid desktop, but where (if possible) do I put it so it will also be avalible in the lucid login screen ?

I have just did an upgrade from 9.04 to 9.10. I am planning to go to 10.04 . After the upgrade everything was ok but I noticed the GRUB was still legacy. So I updated my GRUB to GRUB2. Now when I boot, after entering my logon-id and password, it just brings me back to the login-id screen (to logon on). Any indication of what is wrong and how I should fix this ?
I have no encryptions. [added comments] Currently reading thread about login loop bug with 9.10 Followed instructions about possible missing pre-release update but even if it did do updates, I am still login screen looping. Doing additional researches until someone answers with the fix.
did :
CTRL + ALT + F1 switch to one virtual console
sudo service gdm stop

Trying to install ubuntu 11.04 drove me nuts until I found this page .
My system is an ASUS moderboard with an AMD chipset. The solution came when I entered the BIOS and disabled the cool&quiet feature for the chipset.
After installation, I have to keep cool&quiet disabled in order to run ubuntu. Re-enabling cool&quiet results in ramdon restarts or freezing
