CTRL-ALT-Fx doesn't work?

[marvin_ita]

Before opening a ticket in bugzilla I want to be sure is not my fault in some configuration: I'm not able to switch vt using the ctrl-alt-Fx keyboard combo (I'm using KDE).
Can anyone confirm the problem or is only my system?
Thank you

No problems here...

Does ps aux | grep tty show you the consoles tty2-6?

Does ls -la /dev/tty* shows you all devices available for consoles?

If you open a console, become root and try to use "chvt 3", does this work?

Regards!

Thank you for the reply. After startup this morning it seems to work also on my system.

I think I have some other deeper problem: sometimes I notice that X requires high CPU loading (25% e.g. one core of my quad CPU), keyboard leds go mad (numlock, capslock, screenlock light up and off themselves)... and in this case ctrl-alt-fx doesn't work.

Next time it happens I will try with commands you suggested.

I think problem is not X server... looking in /var/log/messages I can find these lines when I get problems:

Apr 2 20:03:36 localhost init: tty (/dev/tty4) main process (6371) killed by QUIT signal
Apr 2 20:03:36 localhost init: tty (/dev/tty4) main process ended, respawning
Apr 2 20:03:38 localhost init: tty (/dev/tty4) main process (6376) killed by QUIT signal
Apr 2 20:03:38 localhost init: tty (/dev/tty4) main process ended, respawning

These lines are continuously generated and start just after

Apr 2 18:17:25 localhost /sbin/mingetty[1572]: tty4: invalid character 0x14 in login name

Seems that mingetty is causing some problem and continuously crash a vt. Notice that I don't use strange characters as login name and these crashes continue while logged in.

I already moved my bug (https://bugzilla.redhat.com/show_bug.cgi?id=575907) opened as X component to mingetty component in bugzilla... while waiting some feedback I would glad if someone can give me any suggestion.

I'm having this problem as well. System Monitor has my cpu at over 50% constantly.

I'm having this problem as well.

There's also another bug (https://bugzilla.redhat.com/show_bug.cgi?id=577482) tagged as blocker for final release of F13.
