Since I installed Ubuntu 18.04, I can not switch to tty3-7 from the login screen. Until Ubuntu 17.10, this worked perfectly using Ctrl+Alt+F3, F4, .. both from login screen and from user sessions. This is a problem, especially if one is installing a fresh installation and is messing around with /etc/fstab
.
I have read that the numbering of tty's changes, e.g. in How do I switch between console mode and GUI in 17.10? but I do now know why changing to terminal does not work from the login screen.
Is there a workaround for that?
Edit When I try to switch, i.e. p.e. hit ctrl+alt+f4, nothing happens (not even a short freeze or so). If I log in and do the same thing, I see the terminal, can login and everything works fine. If I then lock the screen, I can still switch to the terminal.
My graphics card is a RX 480, the mainline drivers are (as far as I know) integrated in Kernel 4.15 and should therefore work. Furthermore, it works with Ubuntu 17.10 with Kernel 4.15 (mainline kernel), so I assume the graphics driver are not the problem.
ctrl+alt+f3
works properly. Also for me what seems to be the problem is that it seems to attempt to switch but the display freezes on what the login screen was showing. If I pressctrl+alt+F1
then I get back to a working login screen. I have been trying to find a related ubuntu bug but was unable to.
