CentOS 5 :: Where Greeter Application Keeps Crashing
Oct 29, 2009
My web server has Centos 5.3 installed and uses webmin for the administration.Recently the login hangs on a black background with the mouse animation.After a long time I get the message "The greeter application appears to be crashing. Attempting to use a different one."I click OK and the message just repeats.
The web server is running fine and all the applications are still active.I can access the server via SSH.Also, I can login via my vncserver from another computer and access the gnome and kde interfaces.

I have an application running in my machine.I copy the source code to make it run in another machine.I copy the libraries that are needed and paste it to the other machine.I am able to build without any problem and I get the executable. As soon as I start executing,the application crashes with the following message.
0x00110416 in __kernel_vsyscall ()
#0 0x00110416 in __kernel_vsyscall ()

I'm using Centos 5.3 with xen to virtualize some virtual machines (mostly windows 2003).
It works perfectly fine excepted one thing :
Each monday morning, the server is crashed with nothing noticeable in the logs that help.
Since it allways happen between sunday 22h00 and monday 05h00, I suspect a crash when running some cron tasks...
The server works fine. I look at cron.weekly and deactivated makewhatis.com which is the only task apart 0anacron...
But it makes no difference.
I really don't see what can cause such a regular failure... As I am more specialist on Debian, there may be some specific tasks running every week on centos I didn't noticed.

1st of all, I use my centos mainly as a desktop PC. It started about a few weeks ago when i did a yum update and there was a huge number of files to update. I think it was since then (really not sure) that my gnome panel kept crashing. There was a bug report text but no bug number. Changing new user profile, gnome panel hung as well.

Recently switched my home server from Gentoo to CentOS and have been getting kernel panics consistently since I made the server "live". The machine was built with all new hardware. I'll post relevant configuration info and picture of the kernel panic below. So far all kernel panics have been with kernel "2.6.18-164.9.1.el5.centos.plus", right now I am testing with the kernel listed below to see if it does the same thing (2.6.18-164.9.1.el5).
justin@empire justin $ uname -rmi
2.6.18-164.9.1.el5 x86_64 x86_64
justin@empire justin $ rpm -qa |grep kernel |sort
kernel-2.6.18-164.6.1.el5
kernel-2.6.18-164.6.1.el5.centos.plus
kernel-2.6.18-164.9.1.el5

Use python as example, I have 64bit python 2.4.3 yet I can't found rpm for 32bit one so I try to build it.Use default make or make --enable-readline is ok, python make cannot use CFLAGS, can use OPT and LDFLAGS to add -m32, yetit seems can only search for 64bit lib, or else crush.[Moderator edit: Moved from CentOS-4 to CentOS-5 forum.]

I have a dual monitor setup using TwinView running an up-to-date Ubuntu 11.04 amd64. The GDM (login) greeter is displayed in the center of the screen, and thus, one half of the greeter is on the left monitor and the other half is on the right monitor. I've been trying to find away to move the greeter to only one monitor. I've searched Google and the forums for an answer.
Here's what I've tried:
1) gmdsetup => does not have an option to position the greeter
2) gconf-editor => does not have an option to position the greeter
3) ubuntu-tweak => does not have an option to position the greeter
4) Tried these settings in
/etc/gdm/custom.conf, /etc/gdm/gdm.conf,
/etc/gdm/gdm.conf-custom, /etc/X11/gdm/gdm.conf:
Code:
[greeter]
SetPosition=true
PositionX=200
PositionY=300
5) Mucked around with
/usr/share/gconf/schemas/gdm-simple-greeter.schemas ,
/usr/share/gdm/gdm-greeter-login-window.ui,
/var/lib/dpkg/info/gdm.conffiles

System is Wheezy 7.9 with lightdm and MATE desktop.
I have 128GB SSD with various partitions for operating systems and a separate HDD for the /home folders for each OS. Wheezy is my primary system, the others, apart from the original XP are experimental.
/etc/lightdm/lightdm-gtk-greeter.conf is
Code: Select all#
# background = Background file to use, either an image path or a color (e.g. #772953)
# show-language-selector (true or false)
# theme-name = GTK+ theme to use
[code]....
The problem is that each time I use the Ubuntu system and I change back to Debian, the greeter background contains snippets of whatever was displayed while I was in Ubuntu. What I don't understand is how this can happen, given that the operating systems are installed in separate partitions with separate /home partitions as well. After I have used Debian and restart, the greeter screen is clear, as it should be.URL....

I would like to be able to exclude a certain user name from the list presented by the Greeter. Is that possible? I tried adding:

I today upgraded to 11.4 using a downloaded DVD.
I was at 11.3/kde4.6.1. I did a clean install of 11.4, reusing my /home partition from 11.3. This is a desktop, legacy ATI (uses RADEON driver)
After the install process, I ran YAST-Software Management to grab recent updates.
Rebooted system, all seemed OK.
I then added the KDE46/11.4 repo, ran YAST and performed a "Switch to files in this repo" to move to 4.6.1.
I logged out, but cannot log back in, I simply return to the Greeter GUI after a brief blip.
Logging in to console, I don't see anything definitive in /var/log/* as to what the problem might be.

I have tested this on Ubuntu 10.10 64 bit many times . Use at your own risk.
1. Enter command in terminal.
Code:
sudo cp /usr/share/applications/gnome-appearance-properties.desktop /usr/share/gdm/autostart/LoginWindow
2. Close terminal and reboot .
3. Make changes to greeter box using appearance preferences by selecting a theme that supports color change . Use Customize > Controls > Colors to change colors of the box and text.
4. Close Appearance Preferences and log in .
5. Enter command in terminal.
Code:
sudo unlink /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop
6. Close terminal and reboot .

Since I've made the switch to Systemd, I've been having various problems with LightDM.
The most interesting and frustrating problem is when I choose Shutdown or Restart from the XFCE4 shutdown menu, the XFCE4 session closes but then the lightDM greeter pops back up. The system doesn't even try to shut down.
Its as if restart and shutdown both act the same as the Logout button.
Im running XFCE4 4.12 (but same behaviour on 4.10). I have the latest LightDM and the latest Systemd.

I have a laptop connected via HDMI port to different external displays throughout the day. I have configured the displays (Settings > Displays) to turn off the laptop display and set the external display as primary. However, this setting only takes effect after login. Thus, I am unable to see the login screen greeter on my external display because I close the laptop lid, so I am logging in blindly to a gray login screen background.
he issue I am facing is that when I start the laptop with an external display connected, the greeter only appears on the laptop display. The gray login screen background image spans both laptop and external displays and my mouse pointer appears on both displays, so I know both displays are detected and configured as dual displays. But, I am guessing, the laptop display is set as primary while the external as secondary.
I would like to know if there is a way to dynamically switch the greeter between the two displays, regardless of which one is set as primary and secondary. Or, is there a way to configure the system such that if there is an external display connected via HDMI, then it is set as primary, and if no external display is connected, then the laptop display is set as primary?
I have searched all over the net and this forum to no avail. I read a post which required copying the user's ~/.config/monitors.xml file over to /var/lib/gdm/.config/ but this caused my laptop monitor to be turned off at login even when there was no external display connected.
Hardware: Acer Aspire 8730G, Core 2 Duo T9900, 8GB RAM, Nvidia Geforce 9600M GT.
Software: Debian 8.4 Jessie, Gnome 3.14.1, Gallium 0.4 on NV96 (I am assuming this is the Nouveau driver)
Contents of the /etc/X11/xorg.conf file which I generated with the command "Xorg -configure" as root in console mode:
Code: Select allSection "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection
[Code] ...
I suppose I will continue to login without seeing the greeter on my external display.

I installed the pam_face_recognition package to try out but decided couldn't get it working properly so removed it via YAST. Now when I boot up I get a pop up dialogue saying the login greeter widget is missing and to check my configuration. Clicking OK on the pop up drops me to the console login.

After today's update in Maverick, GDM showed no users in the greeter and so it was impossible to input any login info through the GUI, though Alt-F1 console worked. I re-installed GDM and a variety of other packages to no avail.
I found this same problem in an old OpenSUSE message: [URL]
Indeed, console-kit-daemon isn't running, and if I start it by hand and restart gdm, all is fine.
I also see the error message Error org.freedesktop.DBus.Error.Spawn.ExecFailed: Failed to execute program /lib/dbus-1/dbus-daemon-launch-helper: Success#012
in the logs. I also get a similar popup after logging in. It says "You might not be able to connect to the Bluetooth network via this machine."
why console-kit-daemon would fail to start?

Some days ago (2015-09-28) I installed Debian testing amd64. Log in as a user failed and instead of the Gnome UI there was a sad face with the text: „Oh no! Something has gone wrong. A problem occurred and the system can't recover.
All extensions have been disabled as a precaution. Log out“.
The relevant output of journalctl (run as root) said:
etc/gdm3/Xsession[5379]: cannot connect to brltty at :0
- /etc/gdm3/Xsession[5379]: Service 'org.kde.kaccessibleapp' does not exist.
- gnome-session[5379]: x-session-manager[5379]: WARNING: Application 'gnome-shell.desktop' killed by signal 5
- gnome-session[5379]: x-session-manager[5379]: WARNING: App 'gnome-shell.desktop' respawning too quickly
- x-session-manager[5379]: Unrecoverable failure in required component gnome-shell.desktop
[Code] ...
After some investigating, I found three work-arounds.
(1) Use gdm3-autologin: In /etc/gdm3/daemon.conf, remove the double crosses and insert own user name
AutomaticLoginEnable = true
AutomaticLogin = <own user name>
Disadvantage: Only one user can have access to the Gnome ui. If you log out, you enter the gdm3 greeter and … see above.
(2) Turn off gdm3 by running 'systemctl stop gdm3' as root, log in into a terminal as a user and run startx.
(3) Install package lightdm and make it to the standard display manager with 'dpkg-reconfigure lightdm'.
Disadvantage: Energy manager and screensaver settings of the Gnome control center are ignored.
The easiest way, however, especially if there are several users, is logging in via the gdm3 greeter.

I want to set the login to the old default of having to enter a username,password. I've tried to use the configuration editor to achieve this and have ticked the "disable-user-list" option under /apps/gdm/simple-greeter but it makes no difference, the greeter still starts with a user list. It appears that the default valuef TRUE for this function is overriding my choice, but I'm notre why. My next step appears to be to edit /etc/gdm3/greeter.gconf-defaults to change the default value. I haven't actually tried that yet so not sure if it would work but, even if it does, it doesn't seem a very elegant way of setting this up. Is there some simple way of changing the behaviour back to asking for username first?
I seem to remember the whole login process as being more configurable than it is now, with options to choose backgrounds, allow root accest finystem->administration->login_screen only gives a choice between selecting a user or automatic login of a particular user, with no further options available.On a general note, would the old method not be a more secure default than presenting an unauthorised user with a list of login id's to be tried?

I am running 11.4_64, KDE47 (recent update from 46)
I have three Suse Linux pcs on my network.
I'll call them desktop, media center and laptop.
I am logged in to my desktop , I want to open a new session and log in to my media center.
From GUI, I select application launcher - leave -switch user and get a fresh kdm greeter screen.
On the Greeter screen, I select Menu - Remote Login
A window opens displaying three machines - my desktop, my laptop and my media center.
When I move the mouse into the new window to select the media center as the new target machine, the window immediately closes.
I have Xdmcp access enabled in kdmrc on all three systems(and rebooted).
This did work fine back when I was on KDE45 and KDE46.
Is there a new permission or setting now under KDE47?

I have a fresh install of Cent OS 5.4 and am having a problem with Openoffice application not starting up, word processor, spreadsheet, etc. none of them start.
When I try to open word processor, It just loads for a bit says "starting word processor", then closes.
I uninstalled and reinstalled through add/remove software tool and that didn't help. I read somewhere that selinux causes problems with it so I disabled selinux, restarted, and that didn't change anything.

I am fairly new to linux.We have a machine running CentOS 4.4 and sometimes the machine has to be rebooted. Each time after the reboot, I have to SSH in and manually restart one of our application. I have been reading about doing this online and I am a little confuse.Seems like there are multiple possibilities for starting things up. My finding suggest using the inittab file. Then my question is what runlevel do I pass in? Should I use runlevel 1, 2, 3, or 5? Once the runlevel is determine, then how should I name my startup script? I know to use "S" but what number should I give it? Or, another way to approach this is to put my autostart script in the /etc/rc.local file?
