Is there a way to force xrandr to re-read current available display modes?

Thanks. I already have a similar script (even invoked in the same way), even 
more automatic. It scans the list of currently available modes and selects 
the highest available. I have it connected with a hot key. And the point is, 
that if the list of modes is invalid, it cannot work properly. I can still 
type manually vga 1280 at work, but it's not how I like it to be.

By the way - although it is not changing anything - I'm not disabling the 
internal screen, I'm just attaching additional external screen.
