Please notice the line 'Feb 28 23:17:46 cupcake systemd[1]: Started Getty on tty3.' -> LOGIN on TTY3 is therefore possible, I can't just see it because I see still the GNOME-Shell.
My bad. I didn't figured out, that freedesktop.org is the right place for graphic-driver issues with Intel and this is likely only about Intel. https://bugs.freedesktop.org/attachment.cgi My bad.

Created attachment 254993 [details] installed packages (ignore 'linux-4.9.11') Hello! Since Kernel >= 4.10.1 I cannot switch from a Wayland based GNOME-Shell to an FBDEV based TTY with Ctrl+Alt+Function-Key. This worked till Kernel <= 4.9. The screen freezes and shows the GNOME-Shell as it was exactly during the key-press. I cannot see any error or warning in 'dmesg' nor 'journalctl -rb' but hitting Ctrl+Alt+F2 (in most cases GNOME should be running on TTY2, GDM on TTY1) will bring back the GNOME-Shell. Looking at the output of 'journalctl -rb' I noticed that systemd actually does launch getty on the selected TTY, so I tried a blind login and it worked. So it is only a graphical issue. While using the GNOME-Shell on X11 everything still works as usual, returning back to Kernel 4.9.11 and everything works as usual also with Wayland. I noticed some changes to FBDEV and Intel ('fbdev helper ops') in 4.10, but they sound not massive or Wayland related. I'm using a ThinkPad X220 with a Sandy-Bridge i7, therefore it is using a Intel HD3000. Distribution is Archlinux and I'm currently running a self compiled '4.10.1'. Historicall background: For long times switching from Wayland to an TTY wasn't possible if the FBDEV in the TTY was activley used i.e. by fbi(da) to show a png/jpeg/whatever. But I didn't cared much, because initally nobody opens fbi(da) and I was able first to switch to an other TTY without a running fbi(da) and then to the TTY with a running fbi(da). Thank you
