Ctrl+Alt+F7 doesn't switch back to X session in Kubuntu 18.04 Bionic
After I switch to virtual console using Ctrl+Alt+F6 I could not get back to X session using Ctrl+Alt+F7 - only blinking cursor is shown. Tried chvt
- same result. Have to reboot and lost all my opened apps which is very inconvenient. Kubuntu version is 18.04 Bionic.
Could anybody help?
Solution 1:
Other as in Ubuntu 17.10 and later, in Kubuntu 18.04 the default display manager is SDDM, where:
-
tty1
holds the GUI session
get there with Ctrl+Alt+F1 or (sudo
)chvt 1
-
tty2
totty6
hold non-graphical TTY sessions
get there with Ctrl+Alt+F2 to F6 or (sudo
)chvt 2
tochvt 6
-
tty7
and above are unused

SDDM bug report from 2014 about this, which also contains a workaround to make SDDM start on
tty7
Solution 2:
On a Linux text-mode virtual console / terminal, Alt+left-arrow and Alt+right-arrow cycle through virtual consoles.
(X servers disable that keybind, so switch to a text-mode VC first, with ctrl+alt+f2, or any VC number that doesn't have an X session running on it.
If you're ever not sure which VC something is on, or which VTs exist, use one of those to cycle through and see what you find. If there's an X session running on a VC, you will find it.
