The "Fn" trick did not succeed. The keystrokes with "Fn" did not get recognised, these without Fn (i.e., the standard ones) did as shown below.
More info (after a dist-upgrade so last packages are in place) about behaviour today: 1. Boot until gdm graphical login appears. 2. Hit Ctrl+Alt+F?. Nothing happens. Kept at graphical login on virtual terminal 1. 3. Log in and start a graphical X session on any user. 4. Hit Ctrl+Alt+F?. Consoles show as required. 5. Hit Ctrl+Alt+Fxxx to return to the virtual terminal holding the X session. Log out of the graphical X session. 6. Hit Ctrl+Alt+F3. Screen keeps being that of gdm (now mouse cursor gets frozen), but the keystroke Ctrl+Alt+F3 IS recognised... and also subsequent ones: if I then type username and password, I see nothing but gdm on screen but, ... 7. Come back to tty1's gdm graphical login and log in to an X session as any user. 8. Hit again Ctrl+Alt+F3. Voilà: the invisible login at step 6 did actually succeed... the shell propmt is there, waiting for further input. *For your information, there is also unexpected behaviour on virtual terminal switching in my main computer with 17.10 and Nvidia drivers but, well, this is not the place to report 17.10 bugs and mess up things. So, I wonder if it is a gdm issue or any on graphics drivers/framebuffers... whatever... I'm not a developer so, well, my capabilities to diagnose/debug are limited. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1758512 Title: No virtual terminals (CTRL+ALT+F?) when no user logged in; erratic behaviour when user logged in.
