xrandr changes X's orientation too slowly

Question

I'm changing X's orientation with following command

xrandr -o left xrandr -o normal ...

When orientation is changing screen becomes black for a moment then it switches orientation. So how to get rid of this black screen effect ? Maybe some other options should be added to xrandr ?

Answer 1

A solution could be to use Kernel Mode Settings. It is a new feature of the Linux kernel and it does not work with all video drivers.

With kernel mode setting, blank phase may be reduced. But it may also not.

Answer 2

Actually I found the reason of the problem and posted corresponding bug. For details see in my blog http://levonp.blogspot.com/2010/11/xserver-black-screen-delay-when.html

Answer 3

Sorry, because of the way X and randr works, this is not possible.

Answer 4

Actually the transition from normal mode to inverted is being done very smoothly. But transition from inverted to normal mode is being done with black screen effect. Please provide more info on kernel mode settings concerning this
