I'm having problems with the behaviour of ubuntu 22.04 desktop. I don't know why, the block button stoped working. I mean the "lock" icon key in the Logitech MX Keys. I think it stoped working after the lattest update of the nvidia drivers. Moreover, now the Ctrl+Alt+(f1 to f6) changed the behaviour too. The default screen of Ubuntu is lost (the all gray with the credentials in the center). Now I see the black screen with the ugly terminal in the upper left corner Ubuntu 22.04.02 cesarkero-pc tty1 etc.
If I press Ctrl+Alt+f7 I go back to normal desktop.
If I block the user pushing here, the user is blocked and you go to a gnome style different from default. With a purpled screen, with the login at the left size and with the icon that allows you to select between different desktop styles.
The main problem with this screen is that, even if I have my pc configured to never put into suspension, if the user is blocked, the pc is suspended anyway. The default blocking screen in Ubuntu didn't behave that way. I was as easy as pushing the lock button in the keyboard and go.
I have reinstall everything (nvidia drivers included) and every starting by default config of desktop like here.
I hope this all makes any sense and somebody can give me a hint.
