Should I have received my final order eMail already?


In my case yesterday I installed from synaptic a program for autologin, lightdm auto greeter (because there is no graphic user manager preinstalled), and now the main interface doesn't start anymore... I just have a black display with a flash of a dmesg line that it's too fast to be read ...
But can you then log in at the text console or ssh into it and read the dmesg output ?

I can change terminal with ctrl+alt+F1(F2, etc...) and I can see for some seconds the console, I can login and maybe start write something but then all becomes black, with that line that sometimes appears ... trying changing TTY sometimes makes again things visible, but only for some seconds... I have no time to launch commands ...
 
Well, if your root filesystem is on an SD card, maybe you can just remove it and read files in /var/log from another machine ?
Or boot to runlevel 3 (if that Debian is using System V init) by adding "3" to the kernel command line (in the boot loader, if you can do that). Or if that Debian uses systemd (more likely) you might add "systemd.unit=multi-user.target"
You can maybe add "single" to the kernel command line to bott with fewer services started.
It looks like your display manager fails to start, then it is automatically restarted, fails again... forever.
Sorry I don't know how the Pyra OS is setup exactly. Not sure if it helps.
If you can manage to login as root, maybe you have time to type
systemctl stop display-manager
or
/etc/init.d/lightdm stop

I'm not sure.
 
I'm using the internal memory, I still don't have SD cards for this, anyway after a lot of tries, I was able to type and confirm "systemctl stop display-manager", now the display stopped blinking and I can use the terminal in a normal way.

I'll try to remove the last installed package for now, I hope it will undo everything it did to the display manager...

EDIT:

Ok solved, I did "apt-get remove lightdm-autologin-greeter" and after a reboot the graphic interface was again there :)

Fine, then you might want to make sure you can ssh into the machine and get root before trying again to install it and diagnose it until you fix it. I have no idea whether it's a simple configuration matter or anything more complex.
 
The keys in the initial terminal are all messed up, I didn't even found how to make the character pipe.

Anyway I'll make a stand alone thread with the log of what I'm doing, because I suppose that at the beginning many people will need to do the same things.
