Hi! I have a weird problem that may be connected to nouveau.
If I run SDDM/LXDM as my display manager (on Arch Linux), then switch the TTY to tty2, then switch back to tty7 (DM), I get only a blinking cursor

If I switch tty2 -> tty3 (no x server) -> tty7, on the other hand, the DM does *not* crash.
Whenever I switch tty, I get the following message in dmesg:
