...making Linux just a little more fun!

Is there a way to switch the VT of a linux box remotely?
Specifically, I have X running on my desktop, and have trained my wife to click the KDE "switch user" to log in herself (and get her email), which allocates another VT for her.
This works really well -- I can leave myself logged in on VT7, and she can use VT8. Unfortunately, she doesn't know how to switch it back to VT7 when she's done (Ctrl-Alt-F7).
I have a VNC server installed as an X module, that allows me to remotely VNC to my X session (on VT7), but due to X quirks, I can only VNC to it if VT7 is "selected" -- ie, if she's left the machine sitting on VT8, I can't VNC in.
So, I would like to know if there is a way for me to switch which VT is "selected" remotely (ie, SSH in, su to root, and do something to switch VTs).
Thanks in advance! ;-)

Thanks!
OK, now I feel pretty stupid -- somehow I managed to miss the (in retrospect) obvious, after using apropos, esearch, and Google...

You should be able to handle that via the 'chvt' command executed via SSH. Something like
ssh your_wifes_username@host 'chvt 7'should do it.

Dave, don't let it throw you; there are more Unix commands out there than are dreamt of in anyone's philosophy.
ben@Tyr:~$ <Tab><Tab> Display all 2664 possibilities? (y or n)Just recently, while teaching an introductory Unix class in Milwaukee, I saw a short presentation done by one of the client's sysadmins; in it, he discussed using the 'groups' command to show which groups your current UID belongs to. [shrug] As obvious a command as it is - and as obvious of a function as it serves - I had never heard of it before (I always just used 'id', myself.)
