TTY refused to resize with "[Errno 22] Invalid argument" about papertty HOT 5 CLOSED

strace shows me this ioctl(8, TIOCSWINSZ, {ws_row=20, ws_col=62, ws_xpixel=0, ws_ypixel=0}) = -1 EINVAL (Invalid argument)

from papertty.

Hi, sorry about late reply.

Both are running the same buster I presume but do they have the same kernel versions? The TTY resize is pretty finicky in general unfortunately.

No they are not running the same kernel.
The working one is 5.10.17+
The not working one is 4.19.118+

After some experimenting I think I have found the culprit.
If anyone else is facing this error, try increasing the tty1 terminal size... it seems the tty doesn't want to be enlarged but only scaled down.

Thanks for the info. Implementing a proper pseudo TTY support would help here, but that's still pending. I'll close the issue for now.
