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?

Other as in Ubuntu 17.10 and later, in Kubuntu 18.04 the default display manager is SDDM, where:
tty1holds the GUI session
get there with Ctrl+Alt+F1 or (sudo)chvt 1tty2totty6hold non-graphical TTY sessions
get there with Ctrl+Alt+F2 to F6 or (sudo)chvt 2tochvt 6tty7and above are unused

@EricDuminil: A remote user or unprivileged daemon account cannot press keys on your keyboard. Pressing something on the keyboard conveys a high level of privilege: you're physically present and thus capable of taking over the machine in any number of physical ways.

(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.
