Black screen after updating from Trisquel 9 to Trisquel 10 and/or fresh install to Trisquel 10 (FIXED)

Hello,

after updating from Trisquel mini 9 to 10 and do the latest updates & upgrade I get a black screen after the boot process. The same happens after a fresh Trisquel 10 installation.

I had exactly the same problem with Trisquel 9 (upgrade from Trisquel 8 to 9) in the past with my HP nx7300 32bit laptop.

This time it happens on my Toshiba Satellite L300D 64bit laptop.

I was able to fix it by doing the same as last time.

These are the steps I did and it worked for me:

1. A fresh install of Trisquel 10.
2. Don't run a system upgrade after the installation!
3. Install lightdm-gtk-greeter-settings. sudo apt install lightdm-gtk-greeter-settings. This will change a little bit your login screen.
4. Now run a system update. sudo apt update && sudo apt upgrade
5. Reboot your system.

I hope it will work for you too if you have a black screen after the boot process.
