Hi Storm,
$ sudo cat /dev/vcsa cat: /dev/vcsa1: No such device or address
That error is errno ENXIO, see errno(3). One view of the kernel source code has vcs_open() return that errno under some conditions, but I can't help more than that. https://lxr.linux.no/#linux+v6.0.9/drivers/tty/vt/vc_screen.c#L744 if (currcons && !vc_cons_allocated(currcons - 1)) ret = -ENXIO; -- Cheers, Ralph.
