Actually its a bug in stty itself. stty only sets the row or column at a time. So when you do a stty row col it is actually doing TWO mode sets. One to change the number of rows then another to change the number of columns. So to the fbdev driver it looks like this: 640x480 -> 1024x480 -> 1024x768 Now for alot of driver the middle setting doesn't work. So it fails. This bug also effects serial consoles as well. I CC the stty maintain so he can apply the below patch. It is against the latest GNU core utilites. It fixes the issue.
