I have an odd issue with VT switches after upgrading to Fedora 26. I'm
in X, and when I switch VT's systemd creates a getty [1] and it
suspends X [2], however the VT never actually switches to a terminal.
It just sits on a "frozen" X display that has no audio, no video, and
no cursor (as one would expect), until I switch back to VT-1.

I *can* also switch back to to VT-1 using Alt-F1 instead of
Ctrl-Alt-F1, which indicates to me that my keyboard input *is* going
to the console VT -- just my display doesn't match.

Is this related to modesetting? I am using the open source radeon /
radeonsi driver with an HD7500 card, with three monitors.

There are no error messages in any of the usual suspects (journalctl,
dmesg, Xorg.0.log).

Any ideas?

[1] agetty processes after attempting Ctlr-Alt-F2 and Ctrl-Alt-F6:

root     11513     1  0 03:47 tty2     00:00:00 /sbin/agetty --noclear
tty2 linux
root     29928     1  0 11:31 tty6     00:00:00 /sbin/agetty --noclear
tty6 linux


[2] Message in Xorg.0.log at the time of the VT switch attempt:

[ 31645.194] (II) AIGLX: Suspending AIGLX clients for VT switch

Message in Xorg.0.log when switching back to VT-1:

[ 31645.798] (II) AIGLX: Resuming AIGLX clients after VT switch

Raman
