Some time ago I tried to upgrade my ubuntu version from 16.04 lts to 18.04 lts, the PC powered off during the upgrade.
So ubuntu broke making it enter in a log in loop. I follow all the internet tutorials to solve it, even changed from GMD to lightdm, nothing happened, I give up.
Now i start a graphic section opening a terminal (Ctrl + Alt + F6), logging in and using startx.
So I want to disable lightdm because: 1 it doesn't work. 2 to have more resources.
But here is the thing due to the unfinished upgrade of ubuntu I have kinda a "non-ubuntu" version of gnome, when I reboot my pc after the uncompleted upgrade of ubuntu I was surprised due my new desktop had no taskbar, just a little tab that says activities and at the right of it the activity that's running right now.
To be fair it is kinda clean, I accustomed to change between programs running with the keyboard but any ways, any help is appreciated
PD: after I rebooted my pc after the ubuntu upgrade it says that is is ubuntu 18.04
xserver-xorg-core. But beware, there is no easy way to undo this.
