Ubuntu :: Login To Xfce The Screen Goes Black - Flickers A Few Times Then It Brings Back To The Login Screen
Apr 12, 2011
My last setup (years ago) ran fluxbox so because it was familiar I installed it as a secondary to xfce right off the bat. I download a lot of different stuff because I like to try out all the apps I can find but somewhere I broke something. I can still run fluxbox fine, but nither the Xubuntu nor Xfce sessions will run now. Last thing I remember changing was pulse audio(removed it for an experiment I was trying with jack audio), not sure if it is connected but when I try to login to xfce the screen goes black, flickers a few times then it brings me back to the login screen.
I tried failsafe but everytime I do my monitor gives me a "frequency out of range" error. I tried purging and reinstalling xubuntu desktop and xfce settings but I am thinking its my xorg config. My laptop is a Toshiba satellite M305D-s4830 with ATI Radeon 3100 mobile graphics card and I am running Xubuntu 10.10. Unfortunately I also broke the screen, so right now I am stuck with an external monitor till I get a new one.

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
[Code]...

I'm having a bit of an issue. I was transferring some files from an external hard drive onto my desktop computer running ubuntu 10.04...It filled up the hard drive to the max, rebooted and I couldn't login. Did some googling and thought it might be because it was too full so I plugged the ubuntu HDD into my laptop, removed some files and tried again. Still no luck.
What it does is tries to automatically login (that's how I have it set) at the main login prompt, it for some reason is not able to and the screen flickers a bit and shows the login screen. I enter my username and password and it flickers really quick and goes back to the login screen. Does this for my other user account as well. I can login via the command prompt (ctl-alt-f7) and do stuff there, but I cannot login to the GUI.

1st Problem:The problem that I am having is for Ubuntu 10.10. When logging in for some reason it will:1. Login and play the Ubuntu login sound.2. Will start loading the desktop and panels.Right after #2 it goes black and kicks back to the login screen. I am not sure what to do since it constantly does this. It renders the computer useless if I cannot get passed the login page. Yes the username and password are correct.2nd Problem:Before this 1st problem occurred this has also been a problem that has not went away.When I used to be able to login to the desktop I have just the panel on the top of the screen with the traditional Ubuntu "start menu", "system", etc. For some reason the right side which is the other half of the panel will not load. The only solution which fixes it while I am on the current session is to right click the panel and click Minimize/Expand button which toggles to center the panel on the top of the screen. Now when I click Expand its like the problem never happend, but this only fixes it for that session.

I have installed VirtualBox and setup a Windows Vista host, initially with a .vdi of 10gb. That filled up quickly, so I added another 20gb secondary partition, after first trying to allocate a .vdi to a SCSI controller. Configured the drive in Windows (Computer Management), and all seemed ok. I shutdown VB, and rebooted my Linux host (openSuse 11.3). Now I keep bouncing back to the login screen, and can't login to Linux KDE, but can login to a console.I do have the following info:
/etc/fstab:
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part5 swap swap defaults 0 0
/dev/dis/by-id/ata-ST9250410ASG_5VG0B5VS-part6 / ext4 acl,user_xattr 1 1
[code]....
I did see a message before, that I don't see anymore, that said it could not start NFS services due to missing entry in fstab. Another I'm seeing now is it couldn't start the avahi-daemon, no space left on device. This is odd, since I have a 200GB drive, with half of it left, only max 30GB set to VB. Here's my df -k output:
/dev/sda6 Use% is 100%
devtmpfs Use% is 1%
tmpfs Use% is 1%
/dev/sda7 Use% is 46%
So root "/" is mounted on /dev/sda6, which looks like it could be a problem, but why would this suddenly be a problem after working with VirtualBox? Could this be a matter of just freeing up space on /dev/sda6? Like the /tmp folder that's under "/"?

So, I just installed Fedora yesterday. I have been trying out different Linux distros and Fedora was next after Ubuntu and SuSE failed severely. So, I installed F14 yesterday and everything has been great... until I tried to set my JAVA_HOME variable. I followed the instructions here.
After editing $ vi ~/.bash_profile as the site instructs, I proceeded to log-out and log back in...except I can't log back in. I have repeatedly gotten the login screen, selected my account, and entered my password. When I enter my password incorrectly, it says 'Validation Error' and that is not what is occurring. The display goes black for a couple of seconds and I am redirected back to the log in screen.

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.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.

I just bought this desktop from my friend and it runs win 7 and ubuntu 10.04. it worked very well the first two days until I changed the hostname of the system.
I did like: hostname myNewName
And everything worked fine. The problem now is when I start ubuntu and and reach username and password screen , I enter my password to login the screen becomes black and return me again to the screen where I put my password again. If I entered wrong password , the system message stating wrong password. On the other hand, when I try to run ubuntu from live-cd I can login easily and access my account.
My friend told me he removed Naultius package and reinstall it for some reason before he gave it to me. Note windows 7 is working properly.

When I try to login with my username, the one I created when I installed the OS, it seems to try to login but almost immediately kicks back to the login screen. No authentication error it just seems to just logout? The only change I made since last successful login was to add ". .alias" to the .profile file - the only entries in the .alias file are comments and "alias" commands. I have one other username but it is not in the sudo's list of users so I can not change anything in the master login.

My OpenSUSE 11.2 is working fine as samba server, no problems, but I have a problem with KDM.My default init runlevel is set to 5 and every time I try to login at KDM (KDE4), the monitor goes black and returns to the login screen.If I hit Ctrl+Alt+F1 to go to console and start /usr/sbin/console-kit-daemon manually, press Ctrl+Alt+F7 to return to KDM login, everything is fine.What do I have to do to fix this issue?

Every account every option I try. when I login, it just cycles back to the login screen. I have attempted to do a repair install, but to no avail. it happens when I try to boot normally or if I boot into failsafe.

The graphical login screen is loaded just fine. Though very shortly after (a moment after the loading screen could be seen) it crashes back to the graphical login. And that happens no matter what wm I'm trying - gnome, kde3, kde4, e16, e17, even twm.
It happened after the logout after a zypper up yesterday morning. Looking through the list of what packages were upgraded (two machines, both last zypper up'ed last Sunday, checked on the second one after the problem with the first one), the only packages which might be responsible are kwin or qt4.
The graphics card seems to be fine (NVidia 9600), as it happens whether or not I use nv or the propietary driver. Also tried reinstalling it from the repo as well as using the binary blob from NVidia. Has been tested on Windows and games are running fine there, so it shouldn't be the card.
What is strange, is that when calling upon sax2 -r from runlevel three, the initial screen loads nicely, but sax2 crashes back to the cli once one presses 'Change Configuration'. No error messages are being printed.
Any pointers on how I can narrow down the cause (and get it fixed)?
Packages:
OpenSuSE 11.2 + KDE 4 factory & enlightenment & qt 4.6 repos
X.Org 7.4-35.3
Kwin 4.3.98-406.6
libqt4 4.6.1+4.6.20100202-1.1

Alright guys. I need to find a way to enable a black screen screensaver (or turn off the monitor, or something to avoid burn in) while the machine is sitting at the login screen and completely turn off the ability for the computer to sleep. how I can accomplish that?

This problem started within the last few minutes. I run a program in my browser that uploads data from my machine (ubuntu) to another machine (Fedora 13), for manipulation and then spits back the data that does not match our standardised information.
When I tried to run it a few minutes ago, it seemed to take a long time to make the connection. I went back and checked the machine, everything was connected and fine. I decided to reboot the machine from within KDE and then try again. Same result. I went to the machine again and tried to login through KDE, the screen goes black for a few seconds and then returns me to the login screen. I switched over to a virtual terminal and was able to login using the same credentials. I checked the .xsessions-errors file and this is what I am seeing:

I have a few machines set up and running Red Hat 4.1.2-42 in a computer lab. I also have a single test machine running the same version. The machines in the lab work flawlessly.However, when machines are on the login screen, they don't go into power saving mode. That is, after a certain amount of inactivity, the idle login screen should be replaced by a black power saving screen. But this does not happen. The monitor should go into standby (the little green light becomes orange, and the whole screen shuts down until you move your mouse again...you know the drill).I know this is supposed to be the case because this works on the test machine. It just doesn't work in the lab. I think it has something to do with gdm, but I can't for the life of me figure it out.

I would like to post my problems here with Fedora 11 regarding that I am using Dell inspiron 1525, Dual core-N series. I have got two problems:
First;- After I updated my system, I have experienced a a login problem , which is each time I try to login and insert my password correctly it seems that it will login but it comes back to the same login screen as if I did not do anything, but after too many times it works.
Second: I read some posts in a website that talks about configuring the RPM fusion "Repo" and I did all the steps posted there , but after that whenever I try to update or download anything through terminal.... it appears the following:

I'm running Ubuntu 11.04 on my laptop. At work, we are beginning to tinker with running Ubuntu on our student systems (school district). The thing is, Unity and Gnome Shell are new enough that they are not considered right now as viable options to test in. That said, an alternative was needed that was quick on older systems yet very configurable. XFCE. So I installed XFCE on my Ubuntu machine. This way I can tinker with the interface as if I was a student but then I can bounce back to Unity which I do prefer for personal use. The thing is, the login screen switches over to XFCE's. Is there a way to get my regular Ubuntu login screen back?

When she wants to log into xfce, there is only a blank screen. The cursor shows, but there is no way to go any further. No panel, buttons or background.
However, she is able to log in using XDMPC from a local computer without a problem.
There are the processes active under both settings.
Direct login

Questions:
What may have caused xfce not to load some modules on log in? How to fix it, to allow a normal login? How to prevent this problem in the future?

My default desktop environment is Xfce 4.7 (older machine). Monday I came back to work to discover a 17 GB log file in /var/log that ate up my root partition and gave me trouble running. I deleted it, which solved the problem EXCEPT that now when I boot, instead of the Xfce login prompt, I get an X-Windows login prompt. This takes me to a terminal (which apparently reads my .zshrc file), from which I can start an Xfce session by running xfce4-session. How can I get back to booting into the Xfce login screen?

I am trying to set up xfce so that I can be able to switch between multiple users. To do so I seem to need gdm. So I installed it from slackbuilds.org, but the login screen shows rectangles instead of text.

I've been using Ubuntu 10.10 for a while it is so great But for the first time, I've booted my laptop on battery power instead of AC power. I have a black screen on the gnome login and i can hear the ubuntu sound. If i press CTRL+ALT+F2 the screen switch from black to the login (terminal version). The problem only appear when i boot from battery power...if i boot from AC power everything is fine !!! I can see the gnome login page. in fact i've reinstalled ubuntu same problem. I think it's a bug with the release. My laptop is a HP TX2000.

I did a clean install of xubuntu 9.10. I set up an account for my wife on it and now everytime I try to login under my own it keeps going back to the login screen. Sometimes twice last night I had to log in 4 times before it went to the desktop. I have played with some live CD's of ubuntu and xubuntu, but this is the first full install I have done. Before I set up the wife account, I could login first time. Should I try and reinstall and hope for the best or is there something in terminal that could be done?

Ubuntu 9.10, x64. Around 30-40%of the time, after i login, I just get a totally black screen. If i leave it for a few minutes, nothing seems to happen. Whether or not i get login seems fairly random, and I don't notice if there is any common factor- This is always from a clean boot, and i could be on power, or not on power.This is on a HP 6730b, so the video should be a Intel GMA 4500.

I tried to install Ubuntu 9.10 on one of them by default installation. For the moment there is only one user declared. The installation seems OK, except that Ubuntu didn't find my PPPoE connexion. When I logged in, I got a blank screen with the mouse cursor (it moved, but when I left or right-clicked nothing happened) and on the left something looking like two 1-pixel wide menus, as if the system had understood there were a dual screen. These menus could roll and unroll, and I think I even once managed to shutdown by going to the last invisible item thanks to the keyboard arrows (I'm not sure, because I had also clicked on ctrl+alt+suppr, so it could be a delayed effect of that).
I restarted the computer several times, to get no more than that. When I'm in Gnome safe, everything is OK but I don't have any root privilege there (I guess it's normal): for instance, I can't set up the internet connexion. My 20" 4/3 Philips screen is recognized. Then I changed the screen frequency: it's still OK for Gnome safe session, but now, in the Gnome normal session, instead of a black screen with 1-pixel wide menu, I get a black background picture with white light coming from above and reflecting to an otherwise invisible floor. The mouse cursor is moving, but this is the only thing which works.

I just Installed Ubuntu on my PC (win XP-pro) using wubi, by downloading the .iso from webpage and burned it to cd. The installation went fine, but when I login the screen goes black. I can still see my mouse pointer and one vertical pixel line of the desktop. Could it be the graphics drivers, if so how can I update/change them, via rebooting in safe mode and using command line?

I get a black screen (with tiny bits of white on opposite corners of the screen) every time after logging into Kubuntu Lucid AMD64. The only thing I can do is move my mouse pointer over that black screen which doesn't go away. I booted into recovery mode and with command prompt typed "startx" to start graphical mode. That resulted in the same black screen. Then I decided to reboot and install Fluxbox via the command prompt under recovery mode. Now, I'm able to view graphically under Fluxbox after selecting it over the default KDE and logging in. But how do I get regular KDE/Kubuntu to work again? I don't know what happened to make it stop working!
