can't switch from X to tty consoles

[maderios]

Hi
Sometimes with F23, after some hours, I can't switch from X to tty 
consoles (ex, with ctrl+alt+f2). Consoles are frozen, I can switch only 
to tty1, from which I started X with startx. All F23 kernel versions are 
concerned, now kernel-4.4.7. Same problem happens with xfce4, fluxbox or 
Enlightenment-0.20.x. I don't use any display manager like lightdm, gdm, 
etc...
Any idea?

No answer... I reply to myself.
Same problem with kernel-4.4.8-300
It doesnt happen with debian testing or sid installed on another 
partition. So, it's not hardware problem.

I am also experiencing this issue on F23 x86_64 on older hardware.

Haven't tried on mine, but I get X lockups (no keyboard or mouse) on
fully updated F23 Xfce periodically. I can get in via ssh and such, so
the machine isn't dead. Didn't see anything blatant in the logs. Kept
thinking it was hardware (PS, cooling, RAM, something) but after these
reports, I'm not so sure....

FWIW, again
I believe this was mentioned early in this thread but....
For a while, 10 minutes or so, after boot up and login the switching to
tty consoles and back works as it should.  I ran and exited Thunderbird,
Firefox, Terminals and such during which I switched to a tty console and
then back.  Now I can get a console login but have no key board.
Switching back is hard because there is no visible mouse but eventually
I can get to highlight the user selection and log back in.
