Debian Multimedia :: Gdm3 Can't Start Gnome-session

May 7, 2015

I installed jessie from a beta/rc shortly before release on my MacBook Pro 13 Retina and have kept it up to-date with apt-get dist-upgrade. Rcently gdm3/gnome-session have stopped working together. When I log in the screen goes black for a couple of seconds then goes back to the login screen. This happens with "System Default", "GNOME Classic" and "GNOME", but not with "GNOME on Wayland". However, Wayland seems to have some other issues. I haven't tried an alternative dm yet, eg lightdm, but the GNOME desktop does work when started with startx.

I've just used journalctl to get logs of what gdm3 and gnome-session were doing at the time. After booting I waited until the clock reached the next minute (19:55) so I'd know at which point in the logs I'd hit enter on my password. I'll post the gdm log separately in two chunks because the forum server doesn't seem to like text attachments and they're too long for one post.

Log from gnome-session:
Code: Select all-- Logs begin at Thu 2015-05-07 19:54:06 CEST, end at Thu 2015-05-07 19:56:41 CEST. --

Debian Multimedia :: Gnome-shell Does Not Start Logging In Via Gdm3 Greeter

Oct 8, 2015

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.

Debian Multimedia :: How To Log Into X Session As Root Using GDM3

Sep 20, 2015

To use most of my Kali applications, I want to be able to log into an X session as root. I know it is generally a bad idea and I don't want to do it as a rule, but it is useful for penetration testing (e.g. nmap and its GUI don't have most of the useful options when run as a regular user).

So how do I get GDM3 to allow me to log in as root? Currently, if I type in the user name "root" and log in, it just takes me back to GDM3. Could it work to add root to my user group (I really don't want to add all kinds of security holes)?

Debian Multimedia :: Gdm3 / Gnome And Multiple X Sessions

Sep 11, 2015

Running Jessie (with a low-pinned Debian-based repositories added to my sources.list (e.g. Kali, kxstudio) for those packages not currently available on Debian (like the Kali menu of security tools). Running on a HP 15-r189nd (Energy Star) laptop.

First question: How do I get GDM3 to add root as an option during login? I can type the root user name in. I don't need it to show the root user in the user list (would actually prefer to need to type it in), but I do want to be able to start an X session as root, since some of the Kali tools (e.g. nmap) needs root to function fully. If I type in root and try to start, it just takes me back to the GDM3 login.

Second question: When I want to select my Desktop Enviroment/Window Manager in GDM3, the list appears below the little gear so I can only see half of the list (xfce not visible to select). How do I change the GDM3 appearance/settings that will change the position of the DE list?

Third question: How do I get multiple X sessions running simultaneously? What I have been able to do, while logged in as myuser and running X on tty7, is to log into a tty[1-6] as root, and then startx -- :1, but this somehow skips my default desktop manager (GDM3) and boot straight into LXDE (with no menus!). In /etc/X11/default-diplay-manager I have: /usr/sbin/gdm3 ? How do I get startx -- :1 to start a desktop manager?

Fourth question: When I did the above startx -- :1 as root, it would start the X session in the same tty (e.g. tty2) where I was logged in as root running the startx command. It used to be (in older Linux versions) that startx -- :1 would start an X session on tty8 (and the default would be :0 on tty7). Is this the (new) way things are supposed to work? Or is there something wrong with my setup?

Question 5: Once I have started an LXDE session as root, how do I get it to show the full application menu that my regular user can see? Can I just copy the config files over? Which ones? Or is there a better way?

Question 6: Gnome used to start fine. Then I ran Gnome on Wayland once, and now regular Gnome (on X?) no longer runs, but give me a "Oops! Something went wrong" error and Alt-F4 just takes me back to GDM3. Classic Gnome and Gnome on Wayland still runs OK. Should I log a bug report?

i installed oroborus and rox-filer and did not see an entry for either in gdm3's session chooser. i have used these window managers together before and was always able to select the session from gdm. i thought i might have to add an oroborus.desktop file to /usr/share/xsessions, but only found one in /usr/share/kde4/apps/kdm/sessions and it didn't show up when i copied it to /usr/share/xsessions. how can i get oroborus into gdm3's session chooser?

Debian :: Gnome Session Won't Start

Jul 9, 2010

Gnome sessions started hanging during login on a debian lenny box, and I can only think it's related to a recent package update as it was working fine before the last set. It affects all user accounts and hangs before the applications menu or any icons appear on the panels, but after after the top /bottom panels and the desktop background appears.

Debian Multimedia :: Can't Start GUI Session As User

Mar 29, 2016

I recently installed debian 8 stretch with xfce. Since the first time I boot, I have problem starting my X session: from lightdm I always attemped 2 or 3 times before it login (it returned me on lightdm prompt after a short splash screen).

Now it stopped working: the only way I can start xsession is running startx as root. When I try as user it starts the "splash" and return me to the tty with this error message:

Code: Select allServer terminated with error (1). Closing log file(EE)

This is my ~/.local/share/xorg/Xorg.0.log

I try to reconfigure Xorg but the Xorg -configure command result in another segmentation fault.

Debian :: Fglrx And /etc/init.d/gdm3 Start Not Working In Squeeze

Jul 31, 2010

Here is my xorg.conf when I attempt to use fglrx:

Section "Device"

# Driver "ati"
Driver "fglrx"
EndSection

Also, doing /etc/init.d/start/ gdm3 says Starting GNOME display manager: gdm3 but it doesn't do anything. I tried pressing ctrl+f1 all the way to ctrl+f12 and nothing. What does work however is sudo gdm3 (with the "ati"/"radeon" driver --- nothing works at all with fglrx).

I am trying to get fglrx working because I want to fix this compiz issue I've been having here which could be related to the shortcomings of the "ati"/"radeon" driver: viewtopic.php?f=10&t=40991&p=312577#p312577

Ubuntu :: Gdm Will Not Start Gnome Session?

Jul 31, 2010

I'm having issues logging into my system... After authenticating via GDM, the screen goes black with only the mouse showing and remains this way indefinitely. At first the hard disk is active to a similar degree as it was when logins were successful, but then the system (apart from being able to move the mouse) is unresponsive.

If left for long enough so that the screen goes into power-saving mode, moving the mouse brings up the unlock dialogue that you normally get if you set your computer to lock itself after a period of idleness.

I suspect some sort of file corruption, as I have not changed any settings recently. I have forced checks on all of my disks in the hope it would solve this problem. I have also tested logging in on a freshly created user account I created which gives the same result. Also, starting an xterm session from GDM works fine.

Debian Multimedia :: GDM3 Login Screen Orientation

May 23, 2015

I want to set up the GDM login screen in vertical orientation = left = (xrandr -o 1) due to my monitor.

I used Ubuntu and the below method has been working until I switched to Debian8 now.

[URL] ....

Rotate login screen

If you have your monitors setup as you like (orientation, primary and so on) in ~/.config/monitors.xml and want GDM to honor those settings:

Code: Select all# cp ~/.config/monitors.xml /var/lib/gdm/.config/monitors.xml

However,

1 Debian Gnome3 does not create ~/.config/monitors.xml
2 according to dconf editor

the location is

/etc/gnome-settings-daemon/xrandr/monitors.xml

and I tweaked, but no success.

[URL] .... method can be applied to GDM3 directory.

Since I have configured my x rortation only be xrandr command by shell init script, and never had configured by GUI setting, the monitors.xml was not created. When I done with GUI, the file is created as usual.

Then I copied to

/var/lib/gdm3/.config/monitors.xml

Finally works as expected.

Debian Multimedia :: Gdm3 Does Not List Users At Log In Screen

Debian Multimedia :: Gdm3 Hangs After Changing User Name?

Jan 15, 2011

I changed my user name with the following commands:usermod -l $newname $oldnamegroupmod -n $newname $oldname usermod -d /home/$newname -m $newnameAlso replaced every instance of /home/$oldname ith /home/$newname in ~/.config.Now gdm3 hangs with a black screen and wristwatch icon. (I can move the icon with the mouse.) This worked fine with gdm. I've looked for gdm3 files that have /home/$oldname in my home and in /etc and couldn't find anything significant.Anyone have any ideas or suggestions on how to fix this or where to look? For now, I've disabled gdm3, and I'm using startx. This is an installation in virtualbox. I just tried using ctrl-alt-F1, but it dropped me to console in the host system. (Nice rush of adrenaline came with that.)

The only errors in Xorg.0.log are there even with a successful startx. (EE) Failed to load module "xboxvideo" (module does not exist, 0)(EE) open /dev/fb0: No such file or directoryCouple more bits of relevant information - this was a live-build that I installed using refractainstaller. I also changed /etc/inittab to disable auto-login. Here are the changes, original lines commented out, new lines look like the inittab in my regular squeeze install, but I don't think this is the problem (see below.)

#1:2345:respawn:/bin/login -f user </dev/tty1 >/dev/tty1 2>&1

Debian Multimedia :: Gdm3 Black Screen With Cursor After Upgrade

Oct 25, 2015

Yesterday I done an upgrade with apt and since that time whenever I boot up I am presented with only a blank screen and an unresponsive cursor. I cannot switch console using Ctl+Alt+F*. The only thing I can do is Alt+SysRq+(R,E,I,S) which kills gdm3 and gets me back to the console.

* I can get into Xorg fine via the startx command
* As a temporary fix, if I enable automatic login (via /etc/gdm3/daemon.conf) then gdm3 works.

But I can't get the normal authenticated login screen to work.

Output of journalctl for a failed attempt at running gdm3 with verbose debugging enabled:

Code: Select allOct 25 01:24:43 [hostname-removed] systemd[1]: Starting GNOME Display Manager...
Oct 25 01:24:43 [hostname-removed] systemd[1]: Started GNOME Display Manager.

Oct 25 01:24:43 [hostname-removed] gdm3[15863]: Successfully connected to D-Bus

[Code] ....

One other thing worth noting, before upgrading yesterday, I changed mirrors and accidentally pasted in "stable" into /etc/apt/sources.list. So basically I did an initial upgrade, realised my mistake, switched back to testing (which I was on before) and done another upgrade, which is when I noticed this problem.

Debian Multimedia :: No Programs Start In Gnome?

Jul 1, 2010

Linux noob here with a very fresh Debian 5.04 install. Not sure if this is the correct board for this but here goes;*No* programs start in X. Terminal, System Monitor, Epiphany, Gedit, Synaptic Package Manager... They all fail to start.The programs try to start for 15 seconds after which they give up. For example, if I press the Epiphany-icon in the panel I see "Starting Epiphany We..." in the lower-left corner and the mouse cursor changes to the loading animation for 15 seconds but then after that nothing happens and the "Starting Epiphany We..."-icon disappears. I have two users (plus root of course) and the same thing happens with both accounts.

I can start the icons I have on my desktop (Computer, Home folder, Trash and Downloads) and I can Lock the screen/log off/shut down but that's about it. Oh and one more thing; sometimes when I log in everything works just fine, so this whole thing seems a bit random.

Debian Multimedia :: Both KDE And Gnome Won't Start / Change This?

Apr 9, 2011

I'm using Debian 2.6.32-5-amd64 (testing) for several years now. Initial installation was done at least two years ago, without any issues. I do keep my system up-to-date. However, a few months ago, after an apt-get update/upgrade/system-upgrade, I discovered that, if I try to launch KDE or Gnome, I only see a black screen and I actually need to restart my computer. On some cases the system even froze and needed to hardware reset, and run fsck in recovery mode after rebooting. Really very annoying... Since I don't use KDE or Gnome desktops (just a few applications depending on KDE/Gnome libraries), I didn't bother to figure out what is happening. However, others use my computer occasionally, and I would like to get KDE and Gnome working again. I purged and reinstalled everything that had to do with KDE or Gnome, even deleted KDE/Gnome files in my home directory, but the black screens are still there, everytime I try to start any of those desktops. Note that kdm or gdm don't even mention KDE or Gnome as available sessions, although all necessary packages are installed. I have no idea what to do to fix the problem.

Another question: I recently got rid of gdm because it is buggy and tried wdm instead. However, /etc/profile is not read anymore. Apparently, wdm does not use /etc/profile by default. Is there any way to change this?

Debian Multimedia :: Disable Gnome But Start Window Manager

Aug 16, 2011

In the murky world of X11, window managers, session managers and desktop environments I cannot seem to figure out how to achieve the following in Squeeze:

1. Leave Gnome installed, but prevent it from launching when typing startx
2. Have both X11 and my prefered default window manager (blackbox) startup when I type startx (or similar)

My ultimate goal is to leave Gnome installed but "dormant" and when I do a remote ssh -X be able to use X11 forwarding with blackbox.

Debian Multimedia :: Compiz Refuses To Auto Start Properly (with Gnome)

Apr 16, 2011

How to get compiz to auto-start. What seems to be the generally accepted method (from what a few google searches and the debian wiki tell me) of using gconf-editor and changing the window manager from 'gnome-wm' to 'compiz' in desktop > gnome > session > required_components doesn't change anything. The only method I found that did not involve using a terminal and running 'compiz --replace' every time I boot the computer was to add compiz and fusion-icon to the gnome startup apps, but this causes unwanted flickering (it starts metacity and then replaces it with compiz, ie it's simply automating what I would do with the terminal). Autostarting the fusion-icon alone does not start compiz, although it allows me to start it from it's menu if I right click the icon. Note that I sometimes use fluxbox as well, so starting it on boot isn't really an option either.

Perhaps this can be useful :
compiz:
Installed: 0.8.4-4
Candidate: 0.8.4-4
gnome-session:
Installed: 2.30.2-3
Candidate: 2.30.2-3

Debian :: Xfce-session Does Not Start After Boot?

Dec 15, 2010

This morning I did a minimal install of Debian to test out xfce and lxde, purely out of curiosity.I tried LXDE first. For various reasons I wasn't entirely pleased, so I removed it and installed xfce4 in a vanilla openbox session. Upon reboot, I was greeted with the CLI. I generated a new xorg.conf file to see if the transition to xfce had altered it, but was greeted with the CLI again after another reboot. I manually started X with 'startx' and noted that the xfce session manager was installed. The xdm session manager, however, was not.Installing xdm fixed the problem, kind of. I am now greeted with an xdm login screen rather than an xfce session login screen. What can I do to have xfce-session be my default login screen?
