I'm unable to return to the GUI with Ctrl+Alt+F7 (or any of the 12 function keys). I have some unsaved work and I don't want to lose them. Are there any other key combinations that will allow me to switch back?
Here is what I did:
- I pressed Ctrl+Alt+F1 and it showed a text-based login screen as usual
- Then I pressed Ctrl+Alt+F7 and it showed a screen full of text (I can't remember what they were)
- Then I pressed Ctrl+Alt+F8 and it showed log messages that resembles
/var/log/messages. Some entries are from
automount, some from
sendmail, and none are errors.
- Pressing any of the Ctrl+Alt+Fn combinations now has no effect. The cap-lock and num-lock LED no longer respond to their corresponding keys. I can use the mouse to highlight the text on the screen, but nothing else.
Any idea what happened?
I can still login to the system via SSH. GUI applications that I was using (e.g.
opera) are still running and consuming tiny amounts of CPU as usual, as reported by
top. Is it possible to switch back to the GUI via the command line? If possible, I don't want to restart X, because doing so will kill all the GUI applications.

Thanks to Shawn I was able to get back using
Further experiments shows that if I go to the 8th virtual terminal (either by Ctrl+Alt+F8 or
chvt 8), I will not be able to switch to any other terminals using Ctrl+Alt+Fx keys. Now sure if this is a bug.
startxreturned to an existing X session. It always starts a new session on a new console (or the same console, depending on the distro). And AFAIK there is no way to translocate a running client from one X session to another.
chvt 8would do this. But if you keep the Ctrl+Alt keys held down, after you get back into the graphical mode (aka. the GUI / X server), and press another F1-F12 function key, it will not work. You have to first release the Ctrl+Alt keys, and try again, to get out of the graphical mode. I assume this is because the graphical mode doesn't recognise that the keys were pushed down because it wasn't activated at that point in time?
