When you're login is borked

Using lxdm as login manager for entering an openbox desktop environment, I was rather surprised I suddenly experienced a halt halfway starting up.
This was years ago something like that happened.
First I checked if the hard drive by entering another installation on that particular hard drive; that was OK so HD was not damaged.

Another boot into Archbang led to the same failure to get to see lxdm doing, what it is suppose to do.

Using ctl+alt+f2 I was able to start another terminal session, tty2.
Loging  in as user and giving password  I was able to start openbox by using:
startx

I couldn't discover what was wrong with lxdm and decided to check .xinitrc in /user/home/
Was OK with rule

exec openbox-session

Now checking ~/.bash_profile 

making sure following rule was active:

[[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec startx 

As alternative to lxdm I decided to choose to autologin using systemd

Commands:

cp /usr/lib/systemd/system/getty@.service /etc/systemd/system/autologin@.service

Symbolic linking:

ln -s /etc/systemd/system/autologin@.service /etc/systemd/system/getty.target.wants/getty@tty1.service

If the link is already active you can edit getty@tty1.service in /etc/systemd/system/getty.target.wants

by changing

ExecStart=-/sbin/agetty -o '-p -- \\u' --noclear %I $TERM

to in my case

ExecStart=-/sbin/agetty -a paul %I 38400

Reload daemon:

systemctl daemon-reload

And restart service:
systemctl start getty@tty1.service

howto use setup.py file

sudo ./setup.py install

list folder content by only directory names using the terminal

$ ls -d */

is the command that you need in the terminal that is opened in a certain folder to list only the sub-directory names and not the sub-directories content.

I use it for instance to make a text file to list music and ebook folders I have.

Webpush notifications in firefox - howto get rid of them

Visited a site and after that I got small notifications of that site while browsing on others. Never experienced that before; no new extensions that could explain it. This is the explanation :

You can choose whether or not to give permission* for a site to send you notifications by following these instructions:

1. Click the icon to bring up the Control Center.
2. Click the menu next to Permissions and choose a notification option: Always Ask, Allow, or Block. 

*The strange thing that I never gave permission to do this on this site except for accepting cookies. 

You have to visit the site that annoys you and look at the top left next to the email address to find the I icon. Click on the I and then on the right arrow button and then on More Information at the bottom. Then you will see a few tabs and can you choose the permission tab and  change allow to block.
