Can't go back from tty to a graphic session by Ctrl+Alt+Fn

Hi,

since updating the kernel from 6.10.6.arch1-1 to 6.10.7.arch1-1 followed by a restart, I'm unable to get back from Ctrl+Alt+F2 tty2 to the graphic session with Ctrl+Alt+Fn, n = 0 to 9. As long as I don't log in as user or root I can still go back by pushing Ctrl+Alt+F7, but if I log in, then with or without running the exit command first, Ctrl+Alt+F7 doesn't work anymore, I need to restart the machine with Ctrl+Alt+Del.

Regards,

Ralf
