Debian Multimedia :: Lightdm Loads Twice After Booting Up
Mar 6, 2016
I have an odd issue -- fairly fresh Debian Testing install, using Lightdm.
After booting up, Lightdm starts, and then a moment or two later restarts. As a result, any keystrokes captured by the first run (e.g. the first few characters of my username) are lost. My lightdm log is:
Code: Select all[+0.00s] DEBUG: Logging to /var/log/lightdm/lightdm.log
[+0.00s] DEBUG: Starting Light Display Manager 1.16.7, UID=0 PID=827
[+0.00s] DEBUG: Loading configuration dirs from /usr/share/lightdm/lightdm.conf.d
[+0.00s] DEBUG: Loading configuration from /usr/share/lightdm/lightdm.conf.d/01_debian.conf
[+0.00s] DEBUG: [SeatDefaults] is now called [Seat:*], please update this configuration
[Code] ....
This log shows me seeing the login screen, waiting for it to restart, and then logging in correctly on the first attempt.

In Jessie the lightdm login screen does not bring up a lightdm-gtk-greeter dialog box but what seems to be some other one. I can increase the font size by modifying the /etc/lightdm/lightdm-gtk-greeter.conf file, but the login dialog box will not grow to accommodate the larger font (old eyes). The lightdm-gtk-greeter dialog box in Wheezy was a rectangle with a glyph of a console centered in its upper portion, and all the files I have examined indicate that this should be the same in Jessie, but instead the login screen in Jessie displays a narrower rectangle with a head-and-shoulder stylization off to the left.

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 installed debian 7 with lightdm and MATE 1.8 (from backports) on a new PC.
Since the first day the mose keeps disappearing. For example when I click on something, the mouse disappears and only comes back when I move it. Sometimes it already disappears when hovering over a button (especially annoying when it happens while you try to resize a window).
That problem did not happen for example in LXDE, which I installed just to test that.
I did install MATE 1.8 on several laptops/PCs so far, never hat that problem. Maybe it's because of quite recent hardware?

I'm using MATE with Lightdm as display manager in Jessie and I've been using a very simple script run from /usr/share/lightdm/lightdm.conf.d/01_debian.conf to slow down the mouse cursor, something like
Code: Select all#!/bin/bash
xinput --set-prop 10 269 -1
xinput --set-prop 10 267 1.100000
the script was placed in my ~ and called from 01_debian.conf , and so far it used to work.
Lately this script wasn't executed properly, most likely because I had unplugged the mouse from its usb port and then plugged again in a different port, and as a result Lightdm wouldn't start at all.
After much trying, because this by coincidence happened after the update to 8.4, I realized that it wasn't a serious failure of the X server as I suspected (the update included a new version of the flgrx driver), but a simple matter of Lightdm failing because of this script: in fact, I could still manually start the session with startx as regular user, although this only gave me access to a LXDE session instead of MATE (I have also the LXDE environment because when I installed Jessie I did use the LXDE version and then added MATE).
What happened was that the mouse properties were scrambled up, so xinput --set-prop 10 269 -1 had now to be something like xinput --set-prop 10 268 -1 and so on - therefore the script failed and in turns Lightdm failed as well.
-is this supposed to happen when you unplug the mouse and then plug it back in a different usb port? It reminds me of some windows-like behavior, where usb peripherals had to be always in the same port to work properly.
-is Ligthdm supposed to fail because of this, or is it kind of a bug? It looks weird to me that instead of simply not executing the script, the whole display manager fails.
In testing, with an identical setup, as a matter of fact the script failed as well (it's on another partition on the same hardware) but Lightdm started as usual.
-when trying to modify the mouse properties in that script, I couldn't get them right again: what looked correct in the booted system, was once again off at the next reboot (i.e. property 269 was 270 again and so on), therefore I ditched the above setup and placed everything in the .xsessionrc file, and it worked again.
-why startx defaulted to the LXDE environment? where is this setting stored? How could I have specified to start a MATE session instead from command line?

I'm trying to login as guest, but this option does not seem to be available even after changing the LightDM configuration file. I'm on Debian Wheezy + XFCE 4.8. My /etc/lightdm/lightdm.conf looks like this:
[SeatDefaults]
#xserver-command=X
#xserver-layout=
#xserver-config=

Ive installed Ubuntu 10.10 from a SD card (yes my laptop supports booting from SD) and it works fine except the grub does not load. Although I know there are many threads about this Im not sure which one to use because my problem is quite strange.
Im not pretending I understand how grub works but I find it strange:
When I boot from Hard Drive, it boots into Windows without loading grub (I installed ubuntu to an empty partition along the windows on the same drive), however, when I force booting from the SD card, I get the grub window with all the options as expected - ubuntu, mem check, windows 7. Now Im not sure if its grub loading from this SD card (containing ubuntu) or the card somehow runs the grub that is on the hard drive.
My guess is that the partition containg windows (sda0) is flagged as boot and thus the system doesnt even look after grub when booting, however, when theres the SD card it somehow forces booting the ubuntu partition (sda6).
Any idea what I should do? I can boot into Ubuntu, I can access grub etc. I just cant make it load without having the SD card in my PC

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'm running Debian 8.4 on a Lenovo W500 laptop and I recently upgraded from kernel version 3.2.0-4 to 3.16.0-4. Since then I encounter issues with lightdm (I suppose) which manifest themselves in two different scenarios:
1) scenario 1: lightdm fails to start.Instead of showing the graphical login screen, the system boots into terminal. Lightdm seems to be running, but I can't enter the X-Session (Alt+Ctrl+F7 doesn't work), nor can I restart the lightdm via
Code: Select all# service lightdm stop
# service lightdm start
dmesg shows the following (I've only pasted the end of dmesg):
Code: Select all[ 240.100071] INFO: task kworker/0:2:39 blocked for more than 120 seconds.
[ 240.106512] Not tainted 3.16.0-4-amd64 #1
[ 240.112956] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
[ 240.119494] kworker/0:2 D ffff880155155a48 0 39 2 0x00000000
[code].....
and /var/log/lightdm/lightdm.log shows errors of type
Code: Select allGtk-CRITICAL: gtk_container_foreach: assertion 'GTK_IS_CONTAINER (container)' failed
when I then try to shutdown via
Code: Select all# shutdown -h now
the OS gets stuck on a message of the form
Code: Select allirq 17: nobody cared
and eventually I have to force a shutdown by holding the poweroff button.scenario 2: lightdm starts, but can't be stopped/In this case I can login and use the system as usual, but when I try to shutdown either via # shutdown -h now, or via the GUI or the power button, the system gets stuck and I have to force a shutdown by holding the poweroff button.It seems that people had similar issues on other distros (see e.g.: URL... but there doesn't seem to be a good fix so far. I can for now solve the issue by downgrading the kernel to 3.2.0-4, but I was wondering if there is a permanent fix.

Just made a strange discovery, visiting the website: [URL] .... with iceweasel within university's network makes my computer almost unusable. htop's output indicates:
USER: 'root' CPU: '98%' Command: '/usr/bin/X :0 -seat seat0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch'
What this meant to be and/or how this could be circumnavigated?

I have Debian 8.4.0 with lightdm. I'm trying to load some command lines at session startup, putting these in ~/.profile but the file is not loaded. The same procedure works well if I switch lightdm to gdm3.
Anyway, there is some idea to load some script lines at the session startup? The file .bash_profile neither works. I don't want to use ~/.bashrc because it would load every time I open a terminal. Neither to use init.d because it would load for all users.

I have recently downloaded and installed Ubuntu 11.04 inside my copy of Windows. When I boot my laptop, I have the option to either boot in Windows or Ubuntu. When I boot in Ubuntu, I get the login screen all OK. But when the screen loads up, it is missing the top and left hand side navigation bars. It then appears to be trying to refresh itself (unsuccessfully) as after about 30 seconds the screen goes black and then the wallpaper image will come back, still without the navigation bars. This keeps on happening until I reboot the machine. The only way I can get the screen to reboot OK is to run the repair option on boot up.
I have notices that after the above has taken place and I have finally got the system to boot all OK by running the repair option, the system will not connect to my mobile broadband via the USB dongle. Not sure if they are related, but at this point they seem to be.

I installed PyLotRO and copied all the files from the Turbine folder on my Windows HDD.I ran the game perfectly fine, it loaded everything as it should; however, when I log-in, the loading screens run then give me a "Connection failure: You do not have the current client version".I've been unable to find any other problems like this on the site.

After entering runlevel 2 and gdm loads, I only get a black screen. I hear a beep that indicates gdm has loaded, but everything stays black. Trying to switch to a console using ctrl-alt-f1 does absolutely nothing.
At one point, I disabled gdm from starting in runlevel 2, and rebooted. I then typed into tty2 "sleep 60 ; reboot" and in tty1 "gdm" and hoped for a reboot if the graphical login didn't appear. No reboot occurred, my black screen remained.
I've issued acpi=off at kernel command line (from grub) and disabled all acpi services. That seemed to work for a few hours but now I get the black screen again every time. There's no option in the BIOS to switch from acpi to apm, so I've done all I can do on the software side of things.

i just installed the Debian on my old laptop. The install went fine but after that, the GRUB menu loads and freezes. I simply can't do anything. I checked menu.lst and the timeout is set to 5 but still nothing happens. It won't load. I then tried to load with the "super GRUB disk"but the same problem - as soon as it loads from the CD, it freezes and I can't do anything. Before I had Xubuntu on the same laptop but there was no Grub menu. It simply loaded. There's only 1 OS on the laptop /currently Debian/ - no windows, no other Linux.

I just downloaded Debian's live CD .iso file. I put it on a USB stick and booted from it. It loads everything then presents me a login screen. I have no idea what the login and password is I've looked all over google and people said it was user: live pass: live or something like that. I've tried a lot of different combinations with no luck. So does anyone know the real username and password for this?

I had (and still do) a working dual-boot XP/Karmic (GRUB version 1.97 beta4). I shrank the Ubuntu partition and set up partitions and installed Debian 5.04. When I got to the point of installing GRUB, I told Debian to install grub to MBR. On rebooting, Ubuntu was not an option on the NEW (looked different) grub menu.Maybe it was GRUB2? Could boot to either XP or Debian though.
Thought easiest thing was to reinstall Ubuntu since it seems to "see" other OS's more reliably. So I did, and installed GRUB again during its install to MBR. Then, all three were in the GRUB menu (version 1.97 beta4 again), but when tried booting to Debian, got an error (forget the wording), but think it was because the partitions got renumbered when installing Ubuntu.
SO, reinstalled Debian, reformatting the partitions but not deleting them first so the numbering stayed the same. When got to the part for installing GRUB, I told it to skip (I got some kind of error that said "Install failed. This is a fatal error. You will have to boot with an external device..."), hoping now the current GRUB would work.
Now, all three were on the GRUB menu, but when I tried to boot Debian, I got "no such device" and a list of numbers/letters after it. And "press any key to continue", which takes you back to the GRUB menu (version 1.97 beta4, by the way).
O.K., did sudo update-grub in ubuntu and rebooted. Now, Debian 5.04 shows as last entry in GRUB, and choosing it starts a boot, which hangs at "Begin: Waiting for root file system....".
Waiting long enough at the "Waiting for root file system..." hang results in a series of notifications:
WARNING bootdevice may be renamed. Try root=dev/hda3
Gave up waiting for root device. Common problems:
-Boot args (cat /proc/cmdline)
-Check rootdelay= (did the system wait long enough?)
-Check root= (did the sytem wait for the right device?)
-Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/sda3 does not exist. Dropping to a shell!
In Gparted, the partition with Debian root is hdc3, although on the GRUB menu it's listed as /dev/sda3. However, in Gparted the Windows partition is hdc1 and on GRUB it's /dev/sda1, and it boots fine.....
Is my Debian install just borked? Did telling it to skip installing a bootloader (I got some kind of error that said "Install failed. This is a fatal error. You will have to boot with an external device..." ruin it?
If skipping the bootloader install did ruin it, how do you install Debian without borking your current GRUB? That's what happened the first time.
