LightDM endless loop

[machinebacon]

Recently, lightdm shows strange behavior after a dist-upgrade (users of fresh installations beware!)

Symptom: After dist-upgrade and reboot, LightDM starts and closes repeatedly, the user has no chance to step out of this loop (also changing to ttyX doesn't help)

Remedy: edit as root the /usr/share/xsessions/lightdm-xsession.desktop
An entry should look like this:
[Desktop Entry]
Version=1.0
Name=Default Xsession
Exec=startlxde
Icon=
Type=Application

where startlxde is replaced by your Window Manager/Desktop Environnment session starter (startxfce4, openbox-session, awesome, dwm, ...)

and enable auto-login by editing as root /etc/lightdm/lightdm.conf

autologin-user=bbq

where bbq is replaced by your username.

All this can also be done from a live session. Boot into a live system, mount the drive with your BBQ installation:

sudo blkid

Find the device node where LinuxBBQ is installed (for example /dev/sda3)

sudo mount /dev/sda3 /mnt
sudo nano /mnt/etc/lightdm/lightdm.conf
sudo nano /mnt/usr/share/xsessions/lightdm-xsession.desktop
sudo umount /mnt
reboot
