Maybe I can contribute to a > solution. 😀 It's in the linux kernel source, file drivers/s390/char/raw3270.c, line 580: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/s390/char/raw3270.c?h=v6.1-rc5#n580 As a quick test i changed: } else if (MACHINE_IS_VM) { raw3270_size_device_vm(rp); raw3270_size_device_done(rp); } else raw3270_writesf_readpart(rp); to: } else if (0 && MACHINE_IS_VM) { raw3270_size_device_vm(rp); raw3270_size_device_done(rp); } else raw3270_writesf_readpart(rp); so it always uses WSFQ to get the geometry. > When you changed to code to use “LPAR mode” instead of diag 120, did > the console work properly with different geometries? It did, but i haven't tested whether dynamic resizing works. And it's diag210, the 'diag 120' was a typo from me. > That’s the first problem, when the system first comes up, if the > screen isn’t 24X80 the wheels fall off the wagon. > > But the other problem occurs when the console is > disconnected/reconnected and the geometry is different.

I'm normally running c3270 in tmux, so i'm not disconnecting and reconnecting to my session.
